Celebrating National Forest Week

The Paper and Paperboard Packaging Environmental Council (PPEC) has enjoyed celebrating National Forest Week, which is taking place this week (September 17-23, 2023), as the sustainable management of Canada’s forests is fundamental to PPEC members and the circular economy of the paper packaging industry.
 
Environmental sustainability is at the core of PPEC member company operations, and using recycled content is an inherent part of the Canadian paper packaging industry’s business model. And yet, misconceptions surrounding forestry and paper packaging persist when it comes to how paper packaging is made. 
 
In Canada, the major paper packaging grades – containerboard (used to make corrugated boxes), boxboard (used to make boxboard cartons, i.e., cereal boxes), and kraft paper (used to make paper bags) – are either made from recycled, virgin, or blended pulp (a mix of the two).  
 
While most paper packaging made in Canada is made primarily with recycled content – over 80% according to PPEC’s recent 2022 Recycled Content Survey – the paper fibres it was originally made from came from a tree.  
However, the Canadian paper packaging industry doesn’t use much in the way of freshly cut trees, and the little that is harvested must be successfully regenerated by Canadian law; while the paper fibres that are used by PPEC member mills are verified to be responsibly sourced by independent, third-party forest certification organizations. 
 
The Canadian government conserves and protects its forests through strict laws and science-based sustainable forest management practices, which stipulate that all areas harvested on public land (about 90% of Canada’s forests are on public land) must be reforested, either by tree replanting or through natural regeneration (which occurs when new seedlings or sprouts are produced by fallen trees). 
 
According to the latest data from Natural Resources Canada’s State of Canada’s Forests Annual Report, in 2020, the total forest harvest for all lumber (which includes market pulp, packaging, tissue, newsprint, and printing and writing paper) represented 0.2% of Canada’s forest land. 
 
There is also an important distinction between harvesting and deforestation. Deforestation is when forest land is permanently cleared, with trees being removed so that the land can be used for another purpose. In 2020, deforestation accounted for 49,352 hectares of area permanently changed, primarily by the agriculture, mining, oil and gas, and built-up (new homes, ski hills, and golf courses) sectors, which together represent 96% of deforestation in Canada. 
 
Insects represented the largest cause of disturbance to Canada’s forests with 17.7 million hectares of area defoliated in 2020. 
As we celebrate National Forest Week, it is important to understand that when we manage Canada’s forests through the lens of conservation and protection, through careful harvesting and replanting, and through the lens of climate change, as trees capture and store carbon acting as either carbon sources or carbon sinks, we are supporting a healthy forest ecosystem. 
 
It is also important to understand that when we use, reuse, and recycle paper-based packaging, we all play a role in protecting and replenishing our renewable resources, supporting the sustainable management of Canada’s forests, and contributing to the circular economy of the paper-based packaging industry.

Pitting Packaging Materials Against Each Other Misses the Bigger Picture

Recent media articles on the potential of paper packaging to replace some of the single-use plastic items being banned in Canada, such as shopping bags and take-out food containers, miss the bigger picture of waste management and consumption in Canada.
 
Some articles have shared concerns raised by some environmentalists about shifting from plastic to paper packaging materials, but they miss providing fact-based information on how paper packaging is made, how forests are managed in Canada, the function of packaging, the rise of consumption, and the role of the consumer.

The major paper packaging grades made in Canada – which include containerboard (used to make corrugated cardboard boxes), boxboard (e.g., cereal or shoe boxes), and Kraft paper (used for bags and sacs) – are made from a highly recyclable and renewable material that is used repeatedly through the process of recycling.

And yet some articles refer to paper packaging as “single-use,” but on average, paper packaging fibres can be recovered and reused at least 5-7 times.
 
Focusing on the term “single-use” can miss the point about the larger issues surrounding waste management and consumption, and divert attention away from the federal government’s overarching goal of reducing plastic pollution.
 
In essence, all packaging materials – be it glass, metal, plastic, or paper – can be considered single-use, but it’s clear that some are more successfully recycled than others. Paper packaging is one of those successful examples. It has an established recycling system and end markets in place to capture used paper packaging so that those materials can be recovered and recycled to make new paper packaging products again and again.

While most paper packaging made in Canada is produced with recycled content, the paper fibres it was originally made from came from a tree. However, the Canadian paper packaging industry doesn’t use much in the way of freshly cut trees, and the little that is harvested must be successfully regenerated by Canadian law.

Some of the articles refer to deforestation without explaining what that means. There is an important distinction between deforestation and harvesting. Deforestation is when forest land is permanently cleared, with trees being removed so that the land can be used for something else. Harvesting, forest fires, and insect infestations do not constitute deforestation, since the affected areas will grow back.
 
The Canadian government conserves and protects its forests through strict laws and science-based sustainable forest management practices, which stipulate that all areas harvested on public land (94% of Canada’s forests are on public land) must be reforested, either by tree replanting or through natural regeneration (which occurs when new seedlings or sprouts are produced by fallen trees).
 
In addition, paper fibres used by PPEC member mills are verified to be responsibly sourced by independent, third-party forest certification organizations such as the Sustainable Forestry Initiative (SFI), Forest Stewardship Council (FSC), and the Canadian Standards Association (CSA Z809).

While the purpose of some of these media articles is to share environmental concerns surrounding various packaging materials, the articles do not provide information about the function of packaging, or the proliferation of packaging, which should be recognized in any story about packaging.

The function of packaging is to protect its contents, keep the product safe, facilitate transportation along the supply chain, and provide information to the consumer. In some cases that includes mandated information (e.g., ingredient and nutrition labelling, storage information, product use, expiration dates, and bilingual requirements).
 
There is also the reality of the world we live in today that didn’t exist 20+ years ago. It is undeniable that the use of packaging has surged as consumer shopping and dining habits have changed rapidly. The rise of e-commerce and online shopping, along with the increased use of food delivery services, meal kits, and prepared meals in grocery stores, have seen an exponential increase in packaging and in waste.

It’s clear that consumers want convenience but there are trade-offs in society’s decisions. We all have choices we make when making purchasing decisions, just as we have choices in managing our waste.

Everyone has a role to play in minimizing waste and diverting recyclable materials from landfill – businesses that make and sell products and packaging, waste management industry (recyclers, haulers, MRFs), and consumers. Ultimately it is the consumer who decides how to treat their waste and they need to do their part of properly cleaning and sorting their recyclables from their waste and organics to ensure everything that can be recycled is recycled.

Yes, the federal government’s plastics ban will see businesses shift to other packaging alternatives, including paper-based packaging, and our industry will look to meet the demand as needed, creating paper packaging products that are responsibly certified, sustainable, and recyclable.

As the national association representing the environmental interests of the Canadian paper packaging industry, we will stand by our industry and work to communicate the facts about how paper packaging is made. Our industry has relied on recycled content as its feedstock for decades, making investments in recycling equipment, and buying back high-quality old corrugated cardboard and used paper packaging to ensure they have a good supply of recycled paper fibres. Using recycled content is an inherent part of the Canadian paper packaging industry’s business model.
 
When media articles narrowly focus on one material over another, they miss the opportunity of educating and informing the public on the bigger picture of how waste is managed, the proliferation of consumption, and how we all have a role to play in minimizing waste.

Paper-based Packaging Leads the Way for Ontario’s Household Blue Box Program

Paper-based packaging continues to be a success story in Ontario’s household Blue Box program, as measured by marketed tonnage, based on new data released by the Resource Productivity and Recovery Authority (RPRA), the regulator mandated by the Government of Ontario to enforce the province’s circular economy laws.

RPRA’s new Datacall Report summarizes information generated by the 246 programs participating in the Ontario Blue Box Program in 2021, and highlights residential waste management statistics and trends.

Overall, the program saw a decline in the provincial diversion rate to 49.1%, a stat the program has mostly hovered at for the past 10 years as shown in Figure 1 (all charts in this blog are from RPRA’s Datacall Report).

Diversion is measured after the collected material has been processed at a material recycling facility (MRF). So that essentially means that nearly half of what is placed in the Blue Box does not get recycled, which could be for a number of different reasons, such as contamination (food soiled materials, such as used yogurt or peanut butter containers, for example), materials that are not readily recyclable (e.g., hangers, toys), or residents not properly separating their waste and incorrectly placing non-recyclables (i.e. organics, waste) in their Blue Boxes.

Of interest to the Paper and Paperboard Packaging Environmental Council (PPEC) and its members is marketed Blue Box tonnage (Figure 3), which represents materials that have been sorted and processed by a MRF, and then baled, sold, and used in place of virgin materials.

These are materials that are actually recycled and paper-based packaging – which includes old corrugated cardboard, old boxboard, and a portion of residential mixed papers and mixed fibres packaging – leads the way in the most marketed materials with 289,689 tonnes marketed in 2021 (up from 271,433 tonnes in 2020), representing 39% of the total Blue Box marketed tonnage (736,379).

Paper-based packaging leads the way in the most marketed materials with 289,689 tonnes marketed in 2021.

The second largest material is printed paper – newsprint, household fine paper, telephone books, and catalogues – with 20% of marketed tonnes. However, this category continues to decline year over year as more homes go paperless (when was the last time you saw a telephone book?!).

Printed papers have experienced a nearly 66% decline in tonnage from 2016-2021, as shown in Table 4, while paper-based packaging has increased by 72.5% over the same period.

In analyzing the latest Ontario Blue Box data, it’s clear that paper is a success story. More than two-thirds of all paper that Ontario households generate is not just collected but actually recycled through Ontario’s Blue Box program. And much of the recovered paper fibres are supplied to PPEC member mills who use it to produce new paper packaging products, including boxes and cartons, made primarily of recycled content.

The Ontario Blue Box program begins its transition to a new producer responsibility regulatory framework starting this July, which will see producers take over 100% of the operational and financial management of the program by December 31, 2025.

There is no doubt that paper-based packaging will continue to be an important component of the Ontario Blue Box program – and PPEC expects to see a continued increase in paper packaging as brands shift from other types of packaging to sustainable, renewable, and recyclable paper-based packaging – but we will be watching the transition closely. The hope is that a shift to a producer responsibility will result in improved end markets, better sorting by residents, less contamination, and overall higher diversion and recycling rates in Ontario.

Glossary of Key Recycling Terms

The Facts about Sustainable Forestry and the Canadian Paper-Based Packaging Industry

Sustainable forest management is essential to the Canadian paper-based packaging industry and its circular economy. And yet, misconceptions surrounding forestry and paper packaging persist when it comes to how paper packaging is made.
 
With today’s International Day of Forests, the Paper and Paperboard Packaging Environmental Council (PPEC) would like to clear up some of the misconceptions by providing the facts about what is actually harvested, the causes of deforestation, and how the major paper packaging grades are made in Canada.
 
FACT: The Canadian paper packaging industry does not harvest much of Canada’s forests (and what is harvested must be regenerated)
 
While most paper packaging made in Canada is produced with recycled content, the paper fibres it was originally made from came from a tree. However, the Canadian paper packaging industry doesn’t use much in the way of freshly cut trees, and the little that is harvested must be successfully regenerated by Canadian law.
 
According to the latest data from Natural Resources Canada’s State of Canada’s Forests Annual Report, in 2020, the total forest harvest (for lumber and all paper grades including packaging) represented 0.2% of Canada’s forest land, while 600 million seedlings were planted, up from 440 million in 2018.
FACT: The paper packaging industry is not a major cause of deforestation in Canada
 
Deforestation is when forest land is permanently cleared and converted to make way for new, non-forest land use. And according to Canada’s National Deforestation Monitoring System, Canada’s 347 million hectares of forest area is stable, with less than half of 1% deforested since 1990.
 
In 2020, deforestation accounted for 49,352 hectares of area permanently changed, primarily by the agriculture, mining, oil and gas, and built-up (new homes, ski hills, and golf courses) sectors, which together represent 96% of deforestation in Canada.
FACT: Insects are the number one cause of forests disturbances in Canada
 
Canadian forests are most affected by natural disturbances such as insect infestations, diseases, and fires.
 
In 2020, insects represented the largest cause of disturbance with 17.7 million hectares of area defoliated. The second largest cause was fires with 4.3 million hectares of area burned in 2021 (the largest on record since 1990).
FACT: Most paper-based packaging products made in Canada are made from recycled content
 
Most domestic shipments of the three major paper packaging grades made in Canada – containerboard (used to make corrugated boxes), boxboard (used to make boxboard cartons), and kraft paper (used to make paper bags) – are made from recycled content (81.7%).
 
Mills also use sawmill residues – such as wood chips, shavings and sawdust left over from sawmill operations – and some supplement their pulp with virgin fibres from trees.
 
The mixture of using primarily recycled content, along with some new fibres from sustainably managed forests, is an important component to paper packaging’s circular economy.
Existing research shows that paper can be recycled up to seven times, while corrugated box fibres can be recycled up to ten times, and we believe that number could be even higher in Canada given its recycling infrastructure and long-standing residential and business recycling programs. But over time, recycled fibres do weaken, which means a small amount of new virgin fibre needs to be introduced now and again.
 
It is through that important act of recycling that allows paper packaging to be continually collected so it can be reused and remade into new paper-based packaging products again and again.
FACT: Canadian mills use independent certification to verify their paper fibres are responsibly sourced
 
All paper fibres used are verified to be responsibly sourced by independent, third-party certification bodies. In Canada, there are three internationally recognized forest certification organizations: Sustainable Forestry Initiative (SFI), Forest Stewardship Council (FSC), and the Canadian Standards Association (CSA Z809). These organizations assess forestry operations against standards for sustainable forest management, and complements Canada’s rigorous forest management laws and regulations.
FACT: Paper packaging is made from a renewable resource that is sustainably managed, responsibly sourced, and actively recycled 
 
On International Day of Forests, and every day, it is important to remember that Canada’s forests are stable and sustainably managed.
 
When we use and recycle paper-based packaging, we all play a part in protecting and replenishing our renewable resources, contributing to the sustainable management of Canada’s forests, and supporting the circular economy of the paper-based packaging industry.

Article Overlooks the Importance of Recycled Content

In the November 28th New York Times Magazine article, Where Does All the Cardboard Come From? I Had to Know, writer Matthew Shaer does a deep dive on what he refers to as the “cardboard economy” – everything from the history of who invented it, how it’s made, and its global marketplace.

Image adapted from The New York Times Magazine

First off, to us at PPEC, while “cardboard” is a commonly used term that we all understand – the box our deliveries come in – the industry terms are a bit different.

A corrugated box is made from strong paper fibres, comprising a top and bottom layer of paper fibre known as linerboard, and a middle layer, called corrugating medium, which is the wavy part that gives the box its strength.

Image of linerboard corrugating medium

While a boxboard or paperboard carton typically only holds a single item – i.e. cereal or shoes – it does not require the same strength properties as a corrugated box, so you won’t see any wavy ripples in those.

But back to the article. While it is mostly focused on the scale and size of the international market for corrugated packaging – which is expected to reach an estimated $205 billion by 2025, according to the article – it does refer to some of the environmental attributes of corrugated packaging, noting that it is “more recyclable than other shipping methods,” and even likens it to a classic fairy tale:

“Corrugated packaging has a Goldilocks quality to it,” says Tim Cooper, a project director for the
market-research and testing firm Smithers. “It’s easy to produce, it’s strong and it’s sustainable,
because unlike plastic, it comes from a renewable resource.”

We agree that it is strong and sustainable, but there is nothing fictional about the environmental sustainability of corrugated packaging. What Goldilocks needs to understand is that not only is it recyclable, it is actually and actively recycled, allowing it to be reused again and again.

Using recycled content is an inherent part of the Canadian paper packaging industry’s operations. PPEC member mills have been using recycled paper fibres for decades. It makes environmental and business sense to recycle and reuse old paper packaging, including Old Corrugated Cardboard, so it can be remade into new paper-based packaging products again and again, keeping valuable raw material out of landfill.

While the New York Times article reports on its high recycling rates in the U.S., it does not discuss the importance of recycled content, making it sound like boxes are made mostly from trees.

In fact, trees are mentioned in the article 16 times, while recycling is mentioned 11 times.

The sustainable management of forests, and what happens after consumers and businesses recycle their boxes is not mentioned, which may perpetuate the myth that paper-based packaging primarily uses trees in the manufacturing process, which is simply untrue.

In Canada, the average recycled content for domestic shipments of containerboard, which is used to make corrugated boxes is 86.5%, and nearly 80% for boxboard, according to PPEC’s Recycled Content Survey.

The remaining materials used in the mix include sawmill residues and some virgin fibres from responsibly sourced forests. But to be clear, the Canadian paper packaging industry doesn’t use much in the way of freshly cut trees, and the little that is harvested must be successfully regenerated by law. In 2019, the total forest harvest (for lumber and all paper grades including packaging) represented 0.2% of Canada’s forest land, according to The State of Canada’s Forests Annual Report.

We don’t take issue with the New York Times article itself, it is a well-researched piece on what has become a preferred packaging choice, and we expect there will be a continued shift towards paper-based packaging, especially as governments consider banning some types of materials, similar to Canada’s ban on single-use plastics.

But, articles like this should also talk about the critical role that recycling plays in the sustainability of the paper packaging industry. That must be part of any story about corrugated and paper-based packaging because it is an inherent part of our industry’s story.

When we use and recycle paper-based packaging, we all play a part in protecting and replenishing our renewable resources, contributing to the sustainable management of Canada’s forests, and supporting the circular economy of the paper-based packaging industry through the important act of recycling.

Statistics Canada’s New Waste Management Survey Results: Paper Represents 35% of Diversion

On November 15, 2022, Statistics Canada released the results of its biennial Waste Management Survey, containing waste diversion data for 2020, broken down by material type and diversion source (residential and non-residential).

The new data shows that Canadian households and businesses diverted 9,903,027 tonnes of waste in 2020, and of the total amount diverted, 3,502,683 tonnes were paper fibres (which includes newsprint, cardboard and boxboard, and mixed paper), representing 35% of the total amount diverted in 2020.

While paper diversion represents the majority of materials diverted from landfill in Canada, paper diversion has been trending slightly downward year over year since 2014, which could be partly attributed to the continued decline of newsprint materials due to the shift from print to digital.

The next leading category of materials diverted in Canada for 2020 was organics with 32% of the total share of diversion.

Digging deeper into the paper diversion data, of the 3.5 million total tonnes diverted in Canada in 2020, about 44% was diverted through residential sources (ie. Blue Box residential municipal recycling programs), while the remaining 56% was diverted through non-residential sources (ie. Industrial Commercial and Institutional (IC&I) collection).

Below is a breakdown of the sources of paper diversion by province, with the two most populous provinces, Ontario and Quebec, diverting the most paper fibre from both residential and non-residential (IC&I) sources.

Of the other 33% of diverted materials, Statistics Canada reported that “diverting plastic waste to avoid its disposal has become a challenge because of the many types of hard-to-recycle plastics being produced for consumption and entering the waste stream.” Of the 9.9 million total tonnes of waste materials diverted in Canada in 2020, 368,343 tonnes of plastics, or about 3.7%, were diverted.

The Government of Canada has been working to address plastic waste as part of its Zero Plastic Waste Agenda. PPEC continues to monitor government and industry activities related to plastics and we recently wrote about how Canada’s new ban on single-use plastics may impact the paper packaging industry. And while the plastics industry is looking to create a circular economy for its materials through various initiatives, including the Canada Plastics Pact, the paper packaging industry has long held a large-scale circular economy for its materials.

Using recycled materials is an inherent part of our members’ operations. For decades PPEC members have used recycled paper materials as its primary feedstock in making the three major paper packaging grades in Canada (containerboard, boxboard, and kraft paper). They use old corrugated cardboard and other paper-based materials, collected from the backs of factories, supermarkets, office buildings, and from residential recycling programs to make new paper-based packaging.

PPEC’s membership represents several different components of our industry’s recycling supply chain, not just as providers of recyclable paper-based packaging, but also as processors of collected paper materials, and as mills who are recycling and reusing the collected materials, which allows them to be remade into new paper packaging products again and again, keeping valuable raw material out of landfill.

Celebrating Circular Economy Month

Earlier this year, the Circular Innovation Council announced that October marks the inaugural Circular Economy Month. As the Council continues to build on the success of their annual #WasteReductionWeek, they are now expanding the focus to circular economy for the entire month.

In their announcement, they shared “For 20 years Waste Reduction Week in Canada has focused on the concepts of waste reduction and recycling as a key component of our transition to a circular economy…Circular Innovation Council is extending Waste Reduction Week in Canada beyond the third week of October into Circular Economy Month to educate and excite Canadians about the opportunities and benefits of the circular economy.”

SourceCircular Innovation Council

As paper-based packaging is one of Canada’s first circular economies, PPEC is excited to support this campaign. We recognize that focusing on the circular economy is a continual, year-round activity, and there is no doubt that drawing additional attention to it and creating a larger discussion throughout October will be beneficial to raising awareness and enhancing education. 

What is a circular economy, and why is it important?

The Ellen Macarthur Foundation states that “a circular economy is a systemic approach to economic development designed to benefit businesses, society, and the environment. In contrast to the ‘take-make-waste’ linear model, a circular economy is regenerative by design and aims to gradually decouple growth from the consumption of finite resources.” 

And according to the report, “Turning Point – The Expert Panel on the Circular Economy in Canada” from the Council of Canadian Academies, “Only 6.1% of materials entering the Canadian economy come from recycled sources…For Canada to maintain its strong economy and global competitiveness, meet its commitments to reducing carbon emissions and maintaining biodiversity, and keep its people prosperous and healthy, it is critical that Canada’s economy to become more circular.” 

We all have a role to play to play in developing and supporting the circular economy – from businesses actively working to reduce their climate footprint, to governments developing evidence-based policies, and to consumers understanding the environmental impacts of their purchases.  

The Stanford Graduate School of Business agrees as their recent white paper, the Road Toward a Circular Value Chain, states, “…businesses alone cannot win this battle. A successful transition to a circular economy requires all stakeholders…to take action, so that we can leave future generations a better world to live in.” 

Paper-Based Packaging: A Canadian Circular Economy Success Story

Our industry’s circular economy starts with PPEC members and the mills that produce the raw material, which is mostly made up of recycled content. 

From there, converters turn it into recyclable paper-based packaging, which is used by businesses, government, institutions, and consumers. Once used, it is recycled, making its way back to the mill to be remade into new paper packaging products. And the process starts all over again.

Recycling is a critical component of the Canadian paper packaging industry’s circular economy. Recycled content keeps raw materials flowing longer, reducing the need to extract virgin materials. And the average recycled content for domestic shipments of the three major paper packaging grades – containerboard, boxboard, and kraft paper – is close to 82%, based on PPEC’s 2020 Recycled Content Survey

And while research shows that paper can be recycled up to seven times, and corrugated box fibres up to ten times, a recent study from Graz University of Technology in Austria found that fibre-based packaging material can be recycled at least 25 times without losing mechanical or structural integrity. While this new research suggests that paper and board fibres are even more durable than previously thought, we know that we still have work to do to try to better understand how many times paper fibres can be recycled in Canadian recycling systems.  

That circularity only comes with each player playing their part – from the businesses like PPEC members making it a priority to use recycled content in their operations, to consumers actively and responsibly recycling their paper-based packaging.

Using less and making less – just makes sense all around. Paper packaging is a circular economy that utilizes renewable resources that are regenerated, promotes the use of recycled content, and minimizes waste.

Sustainable Forest Management and Canada’s Paper Packaging Industry 

With today’s International Day of Forests, the Paper and Paperboard Packaging Environmental Council (PPEC) would like to explain how sustainable forest management is critical to the circular economy of Canada’s paper packaging industry, and share the latest developments related to how forests can help mitigate climate change.

Environmental sustainability is at the core of PPEC member company operations and the Canadian paper packaging industry, including the sustainable management of Canada’s forests. And yet, misconceptions surrounding forestry and paper packaging persist when it comes to how paper packaging is made.

How Paper Packaging is Made

In Canada, paper packaging is made from virgin, recycled, or blended pulp (a mix of the two); with all paper fibre sources verified to be responsibly sourced by independent, third-party certification bodies.

Most domestic shipments of the three major paper packaging grades made in Canada – containerboard (used to make corrugated boxes), boxboard (used to make boxboard cartons), and kraft paper (used to make paper bags) – are made from recycled content (81.7%).

Mills also use sawmill residues – such as wood chips, shavings and sawdust left over from sawmill operations – and some supplement their pulp with virgin fibres from trees, which represents about 12% of the average paper-based box, carton, or bag.

Canada's Major Paper Packaging Grades Made Primarily from Recycled Content

The mixture of using recycled content – old boxes and other paper materials collected from residential and business recycling programs – along with some new fibres from sustainably managed forests, is an important component to paper packaging’s circular economy.

First, by law, every hectare of commercial forest that is harvested in Canada must be successfully regenerated, so any trees that are harvested are replanted.

And second, through the important act of recycling, paper packaging is continually collected from Canadian residents and businesses, so it can be remade into new paper-based packaging products again and again.

Paper Packaging: One of Canada's Original Circular Economies

And while stats show that paper can be recycled up to seven times, and corrugated box fibres up to ten times, a recent study from Graz University of Technology in Austria found that fibre-based packaging material can be recycled at least 25 times without losing mechanical or structural integrity.

While this new research suggests that paper and board fibres are even more durable than previously thought, we know that over time fibres weaken, which means a small amount of new virgin fibre needs to be introduced now and again, which leads to a second common misconception regarding deforestation.

The Causes of Deforestation and the Role of Regeneration in Sustainable Forest Management

According to Natural Resources Canada’s State of Canada’s Forests 2020 Annual Report, Canada’s 347 million hectares of forest area is stable, with less than half of 1% deforested since 1990.

But there is often a lot of confusion about deforestation, which is when forest land is permanently cleared and converted to make way for new, non-forest land use.

Canada’s annual deforestation rate has been declining since 1990, when it was 64,000 hectares, down to about 34,300 hectares in 2018. During that time, less than half of one per cent of Canada’s total forest area was converted to other land uses.

The major causes of deforestation are due to agriculture, mining, oil and gas projects, new homes, and the development of ski hills and golf courses, which together represent over 90% of deforestation in Canada.

The Major Causes of Deforestation in Canada (2018)

The forestry sector’s (which includes pulp and paper manufacturing and the wood product manufacturing subsectors) share of deforestation represents 1,494 hectares, or approximately 0.0004% of total deforestation in Canada.

And given that the Canadian paper packaging industry doesn’t use much in the way of freshly cut trees, the little that is harvested (0.2% in 2018) must be successfully regenerated (427 million seedlings were planted across Canada in 2018), making packaging’s share of deforestation zero.

Deforestation Facts

The Role of Forests in Mitigating Climate Change

Sustainably managed forests have an important role to play in helping to mitigate climate change, as trees capture and store carbon, acting as carbon sources or carbon sinks: a forest is considered a carbon source if it releases more carbon than it absorbs, and a carbon sink if it absorbs more carbon from the atmosphere than it releases.

The Canadian government knows this and has committed to plant two billion additional trees by 2030, which would represent a 40% annual increase in the number of trees already being planted, and would lower emissions by up to 12 megatonnes annually by 2050 by removing carbon from the atmosphere.

Considering the carbon storage by forests is just one of the many recommendations from a new report by the United Nations’ Food and Agriculture Organization (FAO), Forest Products in the Global Bioeconomy: Enabling substitution by wood-based products and contributing to the Sustainable Development Goals; which speaks to the role renewable forest products have in helping to combat climate change, and explores how wood-based products could help replace fossil-based and GHG-intensive products:

“There is strong evidence at product level that wood products are associated with lower GHG emissions over their entire life cycle when compared to products made from non-renewable or emissions-intensive materials. A review of 488 substitution factors obtained from 64 published studies indicates that the use of wood and wood-based products is generally associated with lower fossil and process-based emissions when compared to non-wood, functionally equivalent products. However, over three-quarters of studies in the literature focus on the construction sector and significantly less information exists for other traditional forest products such as paper for printing, writing, and packaging, or emerging forest products.”

“The document left open for later study the extent to which paper and paper-based packaging may serve as substitutes for non-wood products in the search for those that contribute to the net reduction of greenhouse gases, but there’s little doubt that any product sourced from materials that are grown and regrown are better for combating climate change than the non-paper alternatives.”

In addition to the FAO’s new report, the Forest Products Association of Canada recently released the documentary, Capturing Carbon, highlighting the role of sustainable forest management and wood products in helping to mitigate climate change; and the World Business Council for Sustainable Development released its Forest Sector Net-Zero Roadmap, about the forest sector’s role in enabling the transition to a net-zero economy. These are just a few of the developments related to forestry’s role in addressing climate change, which PPEC is monitoring.

When we use and recycle paper-based packaging, we all play a part in protecting and replenishing our renewable resources, contributing to the sustainable management of Canada’s forests, and supporting the circular economy of the paper-based packaging industry.

On International Day of Forests, it is important to remember that Canada’s forests are stable and sustainably managed.

The Latest Ontario Blue Box Recycling Data for Paper-based Packaging

Paper-based packaging continues to be the largest captured material in Ontario’s household Blue Box program, based on new data released by the Resource Productivity and Recovery Authority (RPRA).

Each year, municipalities, recycling associations, and First Nation communities in Ontario report on their residential waste diversion programs to RPRA, through the annual Datacall. The most recent Datacall Report summarizes information generated by the 250 programs participating in the Blue Box Program in 2020, and highlights residential waste management trends.

Overall, the Blue Box recovery rate – the amount of designated packaging and printed materials recovered as a per cent of the amount generated – increased to 59.9% in 2020, up from 57.3% in 2019.

Of interest to the Paper and Paperboard Packaging Environmental Council (PPPEC) and its members, is Figure 3 from the report, which shows Marketed Blue Box Materials in tonnes. Paper-based Packaging has the largest component with 271,433 tonnes, representing 35.9% of the total Blue Box marketed tonnage (756,984).

Marketed Blue Box tonnes represent the tonnage sorted and processed by a Material Recycling Facility, which are then baled, sold, and used in place of virgin materials.

The second largest material is Printed Paper with 23% of marketed tonnes. However, this category – which includes newsprint, household fine paper, telephone books, and catalogues – continues to decline year over year.

Table 4 of the Datacall Report shows Marketed Blue Box Tonnes from 2015 to 2020, with Printed Papers showing a nearly 62% decline in tonnage over the five-year period.

Meanwhile, paper-based packaging – which includes old corrugated cardboard, old boxboard, and a portion of residential mixed papers and mixed fibres packaging – shows a nearly 73% increase in tonnage over the same period. The most recent year shows a 13.1% increase, which may be attributed to the rise in e-commerce shipments due to the pandemic.

RPRA’s Datacall Report states that 99.8% of Ontario households have access to recycling corrugated and boxboard paper-based packaging. And not only do they have access, Ontario households are actively doing their part to recycle these materials.

The Ontario household recovery rate for Corrugated Cardboard is 98%, and 47% for Boxboard, according to Stewardship Ontario’s 2022 Blue Box Fee Calculation Model.

RPRA’s Datacall Report also offers insights into 10-year trends, including declining newsprint and rising program costs. Overall, Blue Box marketed tonnage decreased by 14.7% from 2010 to 2020, largely due to the continued decline of printed paper in Ontario, which has seen a 64% decrease over the last 10 years. Meanwhile, Net Blue Box costs have increased 35.2% from $203 million in 2010, to $349.8 million in 2020, while revenue received by programs is declining.

The Ontario Blue Box program is currently undergoing transition to a full producer responsibility framework, which will see producers take over 100% operational and financial management of the program by December 31, 2025.

Paper-based packaging is collected for recycling at both the household level, and from the backs of factories, supermarkets, and office buildings (also known as the Industrial, Commercial and Institutional sector). And as recycling plays an important role in the sustainability of Canada’s paper-based packaging industry – allowing PPEC member mills to maintain high levels of recycled content – PPEC closely monitors recycling and waste diversion statistics published by provincial stewardship organizations, Statistics Canada, and other organizations.

PPEC is proud of our industry’s circular economy approach to managing paper packaging products, which are continually collected and recycled through residential and business recycling programs across Canada, allowing them to be remade into new paper-based packaging products again and again.

This National Pizza Day Don’t Forget that Pizza Boxes are Recyclable in Canada

It is National Pizza Day on February 9, 2022, and the Paper and Paperboard Packaging Environmental Council (PPEC) wants to celebrate by reminding you that pizza boxes are recyclable in Canada! You thought we were going to say eat pizza, right? You can do that, too, but don’t forget to recycle that box once you’re done!

Pizza boxes are normally made from corrugated board, and in Canada, corrugated board is made mostly from recycled content. So, once that empty and clean pizza box is placed in the recycling bin – where it is then collected, sent for processing, baled, and sold – that recycled material then makes its way back to our members’ paper packaging mills, where it will get remade into a new pizza box, or another type of paper-based packaging.

That recycled pizza box represents an important slice of the Canadian paper packaging industry’s circular economy. Recycled content keeps raw materials flowing longer, reducing the need to extract virgin materials. And the average recycled content for domestic shipments of containerboard – which is used to make corrugated board – is close to 87%, based on PPEC’s 2020 Recycled Content Survey.

In general, paper can be recycled up to seven times, while corrugated box fibres can be used up to ten times, to make new boxes and other paper-based packaging products. We already thought those numbers were quite good, but a new study from Graz University of Technology in Austria found that fibre-based packaging material can be recycled at least 25 times, without losing mechanical or structural integrity, suggesting that paper and board fibres are even more durable than previously thought.

Thanks to the important act of recycling, it’s likely that your pizza box has had multiple lives, and we want that to continue. But unfortunately, there has been some confusion over the years when it comes to their recyclability.

In the past, it has been suggested that pizza boxes should not be placed in blue box recycling bins because of the grease and cheese scraps. But that’s not true. If you remove the food scraps (eat those crusts!) and any plastic (like that three-pronged pizza saver which is meant to prevent the box top from sagging), that corrugated pizza box is recyclable in Canada.

And when it gets to the recycling mill, the empty pizza box goes into a pulper – which is like a big washing machine – where any non-paper materials are removed through a series of cleaning and screening processes. The paper fibres are then pumped onto a fast-moving screen to form paper or board. The rest of the process involves removing the moisture out of the paper or board so that it can be wound onto big rolls or cut into sheets, which are then shipped to a converter or a box plant, where it is remade into new paper-based packaging.

But what about the greasy residue you sometimes see on a pizza box? Well, in a typical mill’s recycling process, the temperature of the paper sheet reaches up to 240 degrees Fahrenheit – well above 100 degrees Celsius, the boiling point of water and the temperature required for sterilisation – which gets rid of the grease. Though there is not much grease to begin with, as the average grease content of a pizza box found in the recycling stream is approximately 1-2% by weight level, according to WestRock’s Incorporation of Post-Consumer Pizza Boxes in the Recovered Fiber Stream Study.

Paper-packaging is a successful recycling story in Canada and pizza boxes are no exception.

Not only do 96% of Canadians have access to recycling for corrugated boxes, determined through an independent third-party study commissioned by PPEC, but Canadians actively do their part by recycling. PPEC has estimated a national recovery rate for corrugated boxes of at least 85%, with recycling even higher in certain provinces, such as Ontario’s Blue Box program, which has a 98% recovery rate for corrugated.

However, it should be noted that for some Canadian communities, composting paper packaging (including pizza boxes) may be more convenient, such as in Nova Scotia and Prince Edward Island, who are hundreds of kilometres from the nearest packaging recycling mill.

Happy National Pizza Day from PPEC, and don’t forget to recycle your empty pizza boxes so they can be recycled into new pizza boxes!
