Implementation of harmonized Extended Producer Responsibility strategies to incentivize recovery of single-use plastic packaging waste in Canada

Authors:

Abstract and Figures

Mil­lions of tonnes of vir­gin (pri­mary) plas­tic are pro­duced an­nu­ally, while re­cov­er­able (sec­ondary) plas­tic rapidly ac­cu­mu­lates as waste in land­fills and the en­vi­ron­ment. Sin­gle-use plas­tics (SUPs) have short lifes­pans, and most of this waste is gen­er­ated by pack­ag­ing from global food in­dus­tries. Food pack­ag­ing waste com­prises ap­prox­i­mately one-third (8 mil­lion tonnes) of all Cana­dian mu­nic­i­pal solid waste, and only 20% is re­cov­ered for reuse or re­cy­cling. Ex­tended pro­ducer re­spon­si­bil­ity (EPR) strate­gies lever­age cor­po­rate re­sources to re­duce SUP waste gen­er­ated by con­sumers. Im­ple­men­ta­tion of EPR strate­gies al­lows lo­cal ju­ris­dic­tions to gain greater con­trol over their waste streams. Al­though Canada has had a na­tional EPR strat­egy since 2009, it is cur­rently only im­ple­mented for pack­ag­ing in five provinces (e.g., British Co­lum­bia, Saskatchewan, Man­i­toba, On­tario and Québec), and is cur­rently un­der de­vel­op­ment in New Brunswick. In this short com­mu­ni­ca­tion, a case ex­am­ple of EPR im­ple­men­ta­tion in Nova Sco­tia is pro­vided which high­lights the po­ten­tial eco­nomic ben­e­fits for mu­nic­i­pal­i­ties ($14–17 M CAD in es­ti­mated sav­ings), for im­proved solid waste man­age­ment and for in­creas­ing re­cy­cling rates. Fur­ther, a re­gional EPR strat­egy is rec­om­mended for all At­lantic Cana­dian provinces (e.g., New­found­land and Labrador, New Brunswick, Prince Ed­ward Is­land and Nova Sco­tia) now that the Cana­dian fed­eral gov­ern­ment has an­nounced a move to­wards zero plas­tic waste un­der the Ocean Plas­tics Char­ter.

... To this effect, in 2019 DEFRA proposed a reformation of the UK Environment Bill to include the Extended Producer Responsibility for Packaging (EPRP) (DEFRA, 2020(DEFRA, , 2021. The objective of the EPRP is to efficiently implement a PPP taxation framework on packaging producers which incentivises organisational responsibility towards a circular economy (Cai and Choi, 2019) through the use of recycled plastics (Diggle and Walker, 2020), alongside smarter and less detrimental packaging design (Lorang et al., 2022;Pires et al., 2015). Of the 74 items included in the index, nearly half (49%) were single-use packaging for food and drink. ...

Litter is a collective noun that encompasses a large variety of items, ranging from organic to synthetic, and from sharp to inert. Despite this, conversations and regulation on litter continue to group these items with little consideration towards the various levels of associated negative consequences. As a result, the Litter Impact Index (LII) was constructed to score individual items within indicators of toxicity, tenacity, threat and transportability (4T). The product of the index provides a clear visualisation of litter impact on a 0–100 point scale. As a result, it is found that litter items have varying degrees of adverse effects and cannot be considered equally impactful. This index is the first of its kind and was developed with the intention to inform sustainable waste practices, litter related policy, and packaging design by decreasing associated negative impacts.
... Several current and future approaches to mitigate plastic and microplastic pollutions include extended producer responsibility programs, initiatives aimed at reducing single-use plastic consumption, and the Plastics Treaty, which will address the entire plastics life cycle. This treaty aims to curb production, promote a circular economy, establish environmental reporting standards, raise consumer awareness, and enhance performance measures (Diggle and Walker, 2020;Bezerra et al., 2021). Prata et al. (2019) has recommended ten crucial ways for reducing plastic pollution such as regulating production and consumption, implementing eco-design principles, boosting demand for recycled plastics, minimizing plastic usage, utilizing renewable energy in recycling processes, establishing extended producer responsibility for waste management, enhancing waste collection systems, prioritizing recycling initiatives, promoting the use of bio-based and biodegradable plastics and improving the recyclability of electronic waste. ...

Microplastic pollution has emerged as a significant environmental challenge globally, posing threats to biodiversity, marine life, and human health. Studies indicate that marine organisms, from plankton to larger fish species, and ultimately humans are ingesting microplastics, leading to physiological harm such as inflammation, digestive blockages, tissue injury, hormonal imbalance, reproductive failure and biomagnification through the food chain. Therefore, there arises an urgent need and demand for implementing effective and sustainable remediation solutions. Though, various mitigation technologies are developed, less information is available on the advantages and disadvantages of the technological advancements. The present review highlights the significant information available on the sources, types, transport of microplastics along with the analytical methods to detect the microplastic pollutions. The global perspective of microplastic pollutions with respect to Indian Marine scenario was highlighted. The recent and advanced mitigation technologies and solutions in preventing, reducing and recycling these microplastic pollutions were also addressed. This review further underscores the need for comprehensive strategies to monitor, manage and mitigate microplastic pollution, including policy interventions, public awareness campaigns, and sustainable waste management practices. Addressing this issue is essential for preserving the health of India’s marine ecosystems and safeguarding the livelihoods of mankind.
... Research has shown that, for example, in the case of tyres, EPR has increased resource efficiency through increased recycling; and moved tyre management up the waste hierarchy (Winternitz et al., 2019). And implementing these EPR strategies allows local authorities to partially regain control of their waste streams (Diggle and Walker, 2020). For research purposes it is considered important to approach the topic from the perspective of ecommerce businesses, as e-commerce is growing steadily in many industries, not only among large but also small and medium enterprises (Morganti et al., 2014;Visser et al., 2014). ...

In this research, we employed multivariate statistical methods to investigate the perspectives of small and medium-sized enterprises (SMEs) concerning the Extended Producer Responsibility (EPR) regulation and their apprehensions related to EPR compliance. The EPR regulation, which places the responsibility of waste management on producers, has significant financial and administrative implications, particularly for SMEs. A sample of 114 businesses was randomly selected, and the collected data underwent comprehensive analysis. Our findings highlight that a notable proportion of businesses (44.7%) possess knowledge of the EPR regulation’s provisions, whereas only a marginal fraction (1.8%) lacks sufficient familiarity. We also explored the interplay between opinions on the EPR regulation and concerns regarding its financial and administrative implications. Our results establish a significant correlation between EPR regulation opinions and concerns, with adverse opinions prominently influencing concerns, particularly regarding financial burdens and administrative workloads. These outcomes, derived from the application of multivariate statistical techniques, provide valuable insights for enhancing the synergy between environmental regulations and business practices. EPR regulation significantly affects SMEs in terms of financial, administrative, and legal obligations, thus our study highlights that policymakers may need to consider additional support mechanisms to alleviate the regulatory burden on SMEs, fostering a more effective and sustainable implementation of the EPR regulation.
... EPR policy in the Philippines also represents the Philippines broadening its approaches to plastic pollution through other countries' successes. Thomas Lindqvist, a Swede, first proposed EPR as a policy concept in the 1990s as a way to combat waste and remove the responsibility of waste from consumers [33]. European countries originally popularized EPR concepts, but EPR policies steadily grew around the world. ...
... The widespread production of single-use plastics for food packaging is driven by the demand for convenience by the consumer, low cost for the supplier, and lengthened preservation of the product. The onus should be on plastic producers to create alternatives to single-use plastics for their food packaging, such as recyclables, sustainable substitutes, additive manufacturing products, or reusable materials (Cruz Sanchez et al., 2020;Diggle and Walker, 2020;Gillies, 2020). ...

Land-based sources are the greatest contributors of plastic pollution found in aquatic environments. Although plastic debris items spilling into natural watercourses from stormwater outflow sites have been investigated, this study provides details of the plastic items that can be trapped within stormwater drains prior to release. We examined macroplastic (>5 mm) and large microplastic (1–5 mm) debris that accumulated in LittaTrapTM devices at six drains over four seasonal periods in London, Ontario, Canada. Flotation, visual identification, microscopy and Fourier transform infrared spectroscopy (FTIR) were used to determine the drivers of plastic debris deposition. Macroplastics (MaPs) and microplastics (MPs) were identified in all 36 samples, and the totals ranged from 5–158 MaPs and 18–359 MPs per trap. Out of the 118 different MaPs found, the most common items were cigarette butts, wrappers, and expanded polystyrene. The main MPs were fragments, foams, and fibres. The most common macroplastic applications were “smoking”, “food/beverage packaging”, “household”, and non-food or beverage “packaging”. Microplastic particle compositions were mainly polyethylene and polypropylene, but other polymer types fall within the applications of construction (paints and resins), automotive/transportation, and electronics. The summer samples contained the greatest averages of plastic debris, and the drains located in busy pedestrian areas were associated with the highest debris counts. The results support pedestrian traffic as the main driver of plastic debris accumulation in urban London stormwater drains, which is controlled by seasonal weather conditions.

Scope and approach This review evaluates the environmental aspects of SUP in the food packaging industry, considering challenges, impacts and global policies. The focus is on biodegradable packaging alternatives, certification standards, consumer behavior, and the critical role of R&D and patents in moving towards a circular economy. This report integrates discussions on bans and taxes on SUP globally and proposes comprehensive strategies, including extended producer responsibility and consumer education. The technological status and trends in biodegradable plastics are addressed. The impact of certification standards and patents are examined. Consumer demand for eco- friendly packaging is explored, highlighting the complexity of purchasing behavior influenced by demographic and economic factors as well as marketing strategies. The phenomenon of greenwashing and the importance of transparent environmental labeling are also addressed. Key findings and conclusions Global efforts to curb SUP have led to a 68% reduction in polyethylene bags in some regions. Legislative action against SUP is essential, especially for packaging, which accounts for 53% of SUP. Biodegradable plastics currently account for 0.5% of the 400 million tons of plastics produced annually. 44% of patents filed worldwide for biodegradable polymers relate to packaging. Their growth depends on strict standards, transparent certifications and the priority of environmental integrity over the market. The growing demand for biodegradable packaging based on sugar cane, cassava and corn starch reflects consumer awareness. Real progress is hampered by the mismatch between consumer intentions and behavior, economic constraints and greenwashing. A solid legal framework, eco-labels and environmental education are essential.

Corporations are major contributors to the triple planetary crisis. In response to these challenges, the United Nations Global Compact, launched in 2000, encouraged corporations to align their business practices with principles of sustainability and sustainable development. The 2015 Paris Agreement further reinforced corporate commitments to environmental sustainability, recognizing that corporations possess substantial resources and expertise that can be effectively mobilized to address global environmental crises. Corporate environmental leadership has become increasingly critical as businesses face growing pressure from stakeholders to demonstrate environmental responsibility. This chapter examines the interconnected concepts of environmental leadership and corporate environmentalism, exploring their distinct yet complementary aspects in advancing an organization’s commitment to sustainability. Corporate environmentalism operationalizes the environmental leadership vision of corporations through specific policies, practices, and initiatives aimed at minimizing environmental impact, such as environmental management systems, the circular economy, and the integration of the environmental, social, and governance (ESG) framework into corporate strategies. ESG has evolved into a critical set of criteria for evaluating a corporation’s operations, offering a comprehensive sustainability framework. This chapter also discusses strategic solutions to environmental leadership challenges within organizations, as well as the global impact of environmental leadership initiatives across various industries, demonstrating environmental, economic, and social benefits.

Plastics have surpassed traditional materials across numerous industries due to their versatility, durability, and cost-effectiveness. However, their persistence in ecosystems, particularly in soil, presents serious environmental challenges. This narrative review builds on previous work by analysing over 300 studies on plastics in soil, with a focus on degradation and potential reuse. Special attention is given to research published since 2019. The review classifies plastics by resin type and examines their degradation processes under various soil conditions, covering both conventional and biodegradable polymers. Polyethylene emerges as the most extensively studied polymer, while interest in biodegradable alternatives like polylactic acid (PLA) and polybutylene adipate-co-terephthalate (PBAT) is increasing. Additionally, the review highlights advancements in microplastics research, particularly their interactions with co-contaminants and effects on soil organisms. Despite significant progress, challenges remain in standardizing methods for measuring plastic degradation in soil. The review emphasizes the need for further research to establish consistent methods and reliable indicators for degradation, while also exploring innovative recycling technologies for use in agricultural soil management. It stresses the importance of advancing a circular economy for plastics, integrating policy and practical solutions to reduce environmental impacts.

Single-use plastics, or SUPs (plastic bags, microbeads, cutlery, straws and polystyrene) are substantial sources of plastic marine pollution, yet preventable via legislative and non-legislative interventions. Various international legislative strategies have been reported to address plastic marine pollution from plastic bags and microbeads, but these have since been accompanied by recent increasing public awareness triggered by international agencies and organizations. The Sixth International Marine Debris Conference highlighted increasing intervention strategies to mitigate SUP pollution. This study presents new multi-jurisdictional legislative interventions to reduce SUPs since 2017 and incorporates emergence of new non-legislative interventions to mitigate other types of SUPs at individual and private-sector levels that complement or influence legislative interventions. Further, effectiveness of SUP bag interventions (e.g., bans vs. levies) to help reduce SUP marine pollution are presented and range between 33-96% reduction in bag use.

CE has benefitted the global economy for years, including China. For example, developed countries benefitted from cost savings associated with exporting waste to China where there were less stringent Chinese environmental laws, but developed countries failed to incorporate true environmental costs. China also benefitted by importing recyclable waste to supplement its domestic manufacturing industries, yet imported plastic waste was considered inferior, and often unusable (i.e., generating more waste), compared to domestic waste by China's manufacturing industries. In future, the key will be to establish fair-trading systems for waste reutilization across countries globally to reduce waste generation. Firstly, we argue that to reduce waste generation in developed countries, reduced consumption is imperative, since current per capita waste generation in developed countries is much higher than in developing countries. Developed countries, like Canada, need to adopt zero plastic waste strategies by reducing and recycling single-use plastics (Walker and Xanthos, 2018). Secondly, developed countries need to help developing countries deal with their environmental issues, caused by waste reutilization, by transferring waste management and recycling technologies, investing in R&D and training local employees to mitigate potential environmental risks. Thirdly, from a global perspective, implementing extended producer responsibility (EPR) systems across developed and developing countries to help reshape and rebalance the global CE should be undertaken.

In 2017, Prime Minister Trudeau announced five themes for Canada's G7 presidency which began in January 2018. Under the "Working together on climate change, oceans and clean energy" theme, Canada is hosting domestic and international discussions to advance priorities specifically focusing on oceans. These discussions will bring together experts to discuss challenges and opportunities both domestically and internationally, to move toward zero plastic waste and mitigating marine plastic litter, including microplastics (Government of Canada, 2017). Global marine litter is now recognized as one of the most widespread sources of pollution facing the world's oceans. While plastic is a vital material in our economy, there is now a growing international momentum to rethink all stages of the plastics life-cycle from design, manufacture, use, re-use, end-of-life management, and entry and removal from the environment and to take positive steps towards mitigating marine plastic litter. The current life-cycle approach to plastics is economically wasteful, harms ecosystems, threatens livelihoods and vulnerable communities. Plastic is polluting our oceans, and as much as 80% of all plastic in the oceans is land-based. Plastic in our oceans is having a negative impact on all levels of the food-chain, including humans. In 2010, an estimated 4.8-12.7 Mt of plastics entered the world's oceans (Jambeck et al., 2015). Plastic pollution in the oceans comprises of microplastics (<5 mm diameter) and macroplastics (>5 mm). Microplastics comprise: primary microplastics (microbeads), and secondary microplastics, from degraded macroplastics (plastic bags). Recent studies indicate that microplastics (including degraded macroplastics, microbeads and microplastic fibres) in the marine environment may pose more of a risk than macroplastics. Marine debris and microplastics in our oceans, therefore poses a serious global threat to our environment, economy, navigation and now recognized as a potential threat to human health (Pettipas et al., 2016). Yet marine debris is preventable. Like many countries around the world, Canada needs to act swiftly to curb the vast amounts of plastic waste produced. The urgency of this matter has intensified since China stopped importing recycled film plastic from developed countries (Walker, 2018). Many countries around the world, especially across Europe, have already successfully implemented bans of single-use plastic bags (Xanthos and Walker, 2017). Other policies to reduce single-use plastics include banning plastic drinking straws, deposit and return schemes for plastic bottles and extended producer responsibility (EPR), which makes producers responsible for the entire product life-cycle. Following China's ban on importing recycled film plastic, developed countries, including Canada, now need to develop domestic strategies to move towards zero plastic waste by developing reduction and recycling programs to fill this void in the global circular economy. International governments have struggled for decades to reduce marine plastic debris (Xanthos and Walker, 2017). Signed in 1973, the International Convention for the Prevention of Pollution From Ships (MARPOL 73/78) was designed, among other things, to prevent the disposal of plastics at sea, but the problem of marine debris has worsened, likely because the marine debris problem is related to poor waste management on land (Jambeck et al., 2015). More recently, international tools to reduce plastic waste were developed using the Honolulu Strategy, which is a comprehensive and global management framework to help reduce impacts of marine debris. The strategy has been adapted across the globe to meet specific needs of different countries, such as Canada (Pettipas et al., 2016). Strategies include market-based instruments (e.g., levies on single-use plastic bags) for reducing waste and legislation to reduce marine debris (e.g., imposing bans on single-use plastic microbeads and/or plastic bags). Strategies to reduce use of single-use plastic bags vary in range and scope. International governments have strategies to ban sale of lightweight bags, charge customers for lightweight bags and/or generate taxes from stores who sell them. For example, bans, partial bans, and fees have been enacted by some local jurisdictions in North America, but in most cases, national approaches have been undertaken (e.g., across many European countries) (Xanthos and Walker, 2017). Similarly, federal bans for single-use microbeads have been implemented successfully in other countries and the Canadian federal government classified plastic microbeads as a toxin under the Canadian Environmental Protection Act. On January 1, 2018, the Canadian federal government banned wash-off toiletries and cosmetics containing microbeads from stores in Canada (Pettipas et al., 2016). Initial studies on the efficacy of bans or levies of single-use plastic bags have been encouraging. For example, following the introduction of the five pence levy in England, plastic bag use at major supermarkets dropped by 85%; equivalent to approximately six billion fewer bags issued during the first year of implementation (Xanthos and Walker, 2017). Although plastic waste management in Canada is the purview of municipalities, we recommend that the Canadian government seriously consider a federal ban of single-use plastics (including single-use plastic bags and other items such as, plastic drinking straws, plastic cutlery, and plastic packaging). Whilst several municipalities across Canada have successfully implemented bans for plastic bags, other municipalities are still debating the issue (see, for example http://www.cbc.ca/news/canada/nova-scotia/plastic-debate-bags-the-question-what-to-do-with-all-our-junk-1.4496435). We argue that a federal ban will be much more effective than ad hoc bans across different municipalities. Canada's G7 presidency provides a unique opportunity to accelerate domestic action and demonstrate international leadership to reduce use and recycling of single-use plastics and ameliorate marine pollution caused by plastic litter. Therefore, we urge the Canadian federal government to ban as many single-use plastics as is practical and develop strategies to recycle domestic single-use plastic items, where alternatives cannot be sourced, as soon as possible.

Extended Producer Responsibility (EPR) regulations require that producers organize and pay for treatment and recycling of waste arising from their products at end of life. EPR has been effective in implementing some aspects of circular economy. In Europe, 35% of e-waste and 65% of packaging waste have already been recycled (or reused in some cases). This article analyzes the challenges of implementing EPR and provides useful insights for what has worked well and what challenges remain. Identifying and addressing these challenges will be crucial for framing legislation that will move industry and society toward a more circular economy.

China’s ban on imports of recycled plastic from developed countries takes effect this month. It could be a game changer if it weans us off plastic and forces us to seek sustainable alternatives. With no suitable strategies in place for dealing with this extra unexpected plastic, countries must quickly devise and implement alternative waste-management solutions (see also C. M. Rochman et al. Nature 494, 169–171; 2013). Many jurisdictions have legislation that prohibits dumping of plastic waste into landfill. And stockpiling plastic refuse is ill-advised, given the fire risk at storage sites (see, for example, go.nature.com/2dh3mbg). Moves to change consumer behaviour and implement strategies to cut plastic usage are gaining momentum. International policies and financial disincentives to curb the proliferation of single-use plastics (plastic bags and microbeads) are already showing positive results (D. Xanthos and T. R. Walker Mar. Pollut. Bull. 118, 17–26; 2017). These should be extended to include a ban on other items such as plastic drinking straws, and by widely introducing deposit-and-return schemes for plastic bottles.

Plastics have outgrown most man-made materials and have long been under environmental scrutiny. However, robust global information, particularly about their end-of-life fate, is lacking. By identifying and synthesizing dispersed data on production, use, and end-of-life management of polymer resins, synthetic fibers, and additives, we present the first global analysis of all mass-produced plastics ever manufactured. We estimate that 8300 million metric tons (Mt) as of virgin plastics have been produced to date. As of 2015, approximately 6300 Mt of plastic waste had been generated, around 9% of which had been recycled, 12% was incinerated, and 79% was accumulated in landfills or the natural environment. If current production and waste management trends continue, roughly 12,000 Mt of plastic waste will be in landfills or in the natural environment by 2050.

Marine plastic pollution has been a growing concern for decades. Single-use plastics (plastic bags and microbeads) are a significant source of this pollution. Although research outlining environmental, social, and economic impacts of marine plastic pollution is growing, few studies have examined policy and legislative tools to reduce plastic pollution, particularly single-use plastics (plastic bags and microbeads). This paper reviews current international market-based strategies and policies to reduce plastic bags and microbeads. While policies to reduce microbeads began in 2014, interventions for plastic bags began much earlier in 1991. However, few studies have documented or measured the effectiveness of these reduction strategies. Recommendations to further reduce single-use plastic marine pollution include: (i) research to evaluate effectiveness of bans and levies to ensure policies are having positive impacts on marine environments; and (ii) education and outreach to reduce consumption of plastic bags and microbeads at source.

Plastic debris in the marine environment is widely documented, but the quantity of plastic entering the ocean from waste generated on land is unknown. By linking worldwide data on solid waste, population density, and economic status, we estimated the mass of land-based plastic waste entering the ocean. We calculate that 275 million metric tons (MT) of plastic waste was generated in 192 coastal countries in 2010, with 4.8 to 12.7 million MT entering the ocean. Population size and the quality of waste management systems largely determine which countries contribute the greatest mass of uncaptured waste available to become plastic marine debris. Without waste management infrastructure improvements, the cumulative quantity of plastic waste available to enter the ocean from land is predicted to increase by an order of magnitude by 2025.
