It would be an understatement to say that plastic pollution has become top of mind. Images of sea turtles tangled in plastic rings, ocean plastic trash heaps, and the idea that tiny plastic particles reside in fish, our water supply, and even people, have collectively heightened concerns. Here’s something to chew on: according to research, the average American may be consuming more than 70,000 micro-plastic particles a year.
Recycling is an insufficient solution to plastic pollution
To date, market forces and the existing recycling infrastructure have failed to keep consumer plastic waste out of the environment. As a result, people are increasingly looking for government action to help curb the leakage of disposable plastic waste. They aspire to a more systematic approach than the patchwork quilt of local and state responses currently seen across the United States.
The result of the existing system speaks for itself: plastic recycling has been an underachiever. The U.S. recycling rate for plastic was just over 8% in 2017 – roughly the same as in 2010. By comparison, an estimated 42% of plastic packaging waste was recycled in the European Union in 2017, up from 32.5% in 2010. So why are rates in the EU higher than in the U.S. and climbing more rapidly? According to the European Environment Agency, European gains have been at least partly driven by initiatives that take a systematic or circular approach to recycling and resource preservation. Let’s take a closer look.
EU regulations seek to close the loop
Chief among EU initiatives to promote recycling were EU targets introduced in 1994 and 2008 and later by the circular economy packages (2015). Current EU policy calls for:
– A minimum of 65 % by weight of all packaging waste must be recycled by no later than December 31, 2025
– A minimum of 70 % by weight of all packaging waste must be recycled by no later than December 31, 2030,
– A minimum of 50% of plastic by December 31, 2025
– A minimum of 55% of plastic by 2030.
An essential step for the European Commission has been the Circular Economy Package, aimed at “closing the loop.” As articulated by the Ellen MacArthur Foundation, “A circular economy is based on the principles of designing out waste and pollution, keeping products and materials in use, and regenerating natural systems.”
One point of significance from the circular economy perspective is that the goal is to keep materials at their highest state of utility. As such, recycling, even when achieved at a high rate, is still sub-optimal to reduction, reuse, and refurbishment alternatives. The EU Action Plan for the Circular Economy has established an ambitious program of action, with measures covering the entire cycle from production and consumption to waste management and the market for secondary raw materials.
U.S. regulations are a complex patchwork
While we see a systematic approach to plastic waste management in the EU, the United States, by comparison, has a complicated landscape of local and state initiatives. Jurisdictions scattered across the country have established bans or fees for commonly littered plastic items such as bags, carryout containers, and straws. To further muddy the waters, some states have put restrictions in place to prevent future plastic bag bans at the local level, essentially legislation aimed at banning bans.
At the federal level, there is a ban on the use of plastic microbeads (small plastic particles found in personal care products, cosmetics, and detergents), which followed state-level prohibitions already in place. Some experts cite the microbead approach as an example of how the federal government could make use of practical state-level solutions and expand them to provide effective national policies to curb plastic pollution. They say that a federal response to plastic pollution is required to help stop it at the source.
Is federal regulation on the horizon?
One recent development in Washington DC has been the circulation of a discussion draft of legislation aimed at reducing plastic waste. The initial comment period generated more than 150 responses, which bill proponents will consider before introducing the bill in Congress. News reports have referred to the ambitious proposal as “radical” and “sweeping.”
Highlights of the bill, proposed by U.S. Senator Tom Udall (D-N.M.) and U.S. Representative Alan Lowenthal (D-Calif), include extended producer responsibility, a national container deposit program (regardless of container material), and a ban of some plastic items.
The prohibition would encompass lightweight plastic carryout bags, cups and lids, cotton buds, cutlery, plates, straws, snack packaging, and drink stirrers, which would have to be made exclusively from reusable or more sustainable materials instead. There would be a carryout bag fee for paper or other non-reusable bags, with fees to be utilized by a federal fund to support pollution reduction, remediation programs, and innovation research.
Plastic pollution is a critical issue and requires an urgent response. While market-driven solutions have proven to be extraordinarily successful in eliminating waste in some applications, such as reusable packaging systems in B2B supply chains, consumer plastic supply chains are diverse and collectively, very complicated. They will require an innovative and systematic solution on the scale of the EU Circular Economy Package if the U.S hopes to turn the tide on plastic pollution.
PMMI, the association for packaging and processing, recently released its position on sustainability. PMMI believes:
--Packaging plays a critical role in our world. It safeguards our food, protects our medicines, shields our purchases and allows for the transportation of goods; protecting what keeps us healthy and happy.
--The packaging industry has a responsibility to limit its environmental impact. We are driving innovation across all packaging types, throughout the supply chain, to increase the use of recycled materials and reduce the amount of packaging being used.
--Making packaging as sustainable as possible is not about eliminating any single material, but rather making smart, eco-friendly choices that help packaging meet the needs of consumers, and the environment.
--The solution requires a combination of many things, from infrastructure to education to innovation. Everyone has an important role, including consumers,
--The move toward sustainable practices, products and materials is ever-present and a priority in the packaging industry. Sustainable solutions are being thought about and innovated every day so that packaging can continue to play an important role in our lives.
We need packaging to safeguard our food, protect our medicines, shield our purchases and transport our goods; packaging protects what keeps us happy and healthy. Because of its essential place in our world, we have a responsibility to limit its environmental impact.
The solution requires a combination of infrastructure development, education and engagement, innovation, and clean-up efforts. Everyone has an important role, including consumers who must play an active part and be willing to share in the cost of innovation. Our industry is driving innovation; and we see this in the ongoing push to improve sustainability across all packaging types, throughout the supply chain.
This is true for a variety of packaging formats; from the plastic used on bottle caps, to polyethylene terephthalate (PET) bottles, to recycled corrugated card used in cartons and cases and recycled, high-density polyethylene (rHDPE) or recycled polyethylene terephthalate (rPET) film.
Sustainability initiatives in packaging have advanced considerably, leading to an increased use of recycled materials, as well as a reduction in the amount of packaging being used. This is being addressed by redesigns to reduce the footprint of the packaging, careful monitoring of the amount of packaging used to reduce wastage, increased use of biodegradable materials like BioFilms and production of thinner packaging, be that thinner carton walls or thinner film on a wrapping machine. And to facilitate this, OEMs are developing machines with improved functionality to minimize waste and maximize productivity speeds with innovative and environmentally friendly materials.
These are just some of the examples of what the packaging industry is doing – the speed of innovation is rapid. PMMI reports on sustainability issues and innovations regularly, published daily via our Media Group’s digital platforms, monthly in Packaging World magazine and annually in our Innovations Report – a roundup of technologies seen at PACK EXPO, where there is an emphasis on education, ideas and technologies advancing sustainability efforts.
