Moving beyond 100% recyclable goals Scott Breen Thu, 01/28/2021 – 01:15 Numerous companies have set 100 percent recyclable, reusable or compostable packaging goals such as Colgate-Palmolive and Kellogg. Virtually all these companies, though, are not tracking whether their packaging is actually recycled and what new products their packaging becomes. Without this end-of-life tracking, they cannot determine the extent of the economic and environmental impact from how their packaging was recycled. Technical recyclability is only the first step of many questions to determine if your packaging works in today’s recycling system. Other questions include: Is the packaging collected in the vast majority of recycling programs? Can the packaging be easily separated from the rest of the single stream recyclables? Once baled with like materials, does the material the packaging was made of sell for an amount that pays for the cost to collect and separate it and, ideally, provide additional needed revenue to the material recovery facilities (MRF) that separate single stream recyclables? Is the packaging downcycled into a product unlikely to be recycled at its end-of-life?  These questions are harder to answer. Further, some companies may not want to look under the recycling hood. They might fear uncovering negative characteristics for a packaging type that they want to continue using because they’ve invested in it, it provides higher margins than other packaging, or consumers find it attractive. If companies are serious about fixing the U.S. recycling system, they need to go beyond a new willingness to fee-setting and long-term recyclability goals . They need to consider what inputs they are pumping into the recycling system. Material flows One way to answer some of the above questions is to use material flow analyses (MFA). MFAs show visually how materials flow through the waste management system. They make it easier to identify where material is being lost and whether there is downcycling or ” real recycling .” While the whopping 82% of plastic going to landfill is jarring, it is important to look at the end-products that this MFA identifies and what percent actually gets recycled once entering the recycling system. Metabolic’s ” Recycling Unpacked: Assessing the Circular Potential of Beverage Containers in the U.S. ” has a beverage container MFA. One can see that a third of PET is lost during the mechanical recycling process and 40 percent of the glass material collected from single-stream recycling systems is used as landfill cover. The MFA also shows the best performer. It is aluminum cans with 82 percent of used beverage cans entering the U.S. recycling system able to be recovered for high-quality closed-loop recycling into another can, which easily can be recycled at the end of its useful life. Closed Loop Partners (CLP) also has conducted a detailed MFA for a variety of plastic resins. While the whopping 82 percent of plastic going to landfill is jarring, it is important to look at the end-products that this MFA identifies and what percent actually gets recycled once entering the recycling system. End uses vary by resin. One of the top end-uses noted in the MFA is synthetic fiber, which typically is used for clothing. Most new clothing , regardless of if it is made with recycled material, will go to landfill unless nascent solutions are scaled. One extra revolution is far from true circularity. Also consider plastic polyethylene (PE) film in CLP’s MFA. The only PE film that is recycled is the small percent that goes to retail store drop-off and commercial direct bales. So, PE film is technically recyclable . Thus, some companies may count it towards their 100 percent recyclable goal, but it is far from being truly recycled in today’s system. It may be difficult for a company to do an MFA of just its products. Still, companies should look to MFAs of material types and packaging generally to get a sense of if there is ” real recycling ” with their packaging. Revenue source or cost for recyclers The more than 350 residential MRFs in the U.S. are struggling with incessant contamination and often pay more to separate recyclables than they earn selling them.  Companies should consider whether the packaging they put into the marketplace will help recyclers on the back end with added revenue. The consistent, relatively high revenue sources for MRFs are certain kinds of paper ( cardboard ), aluminum beverage cans and certain kinds of plastic ( HDPE ). In fact, one recent study by Gershman, Brickner & Bratton determined that without the revenue from used beverage cans, most MRFs wouldn’t be able to operate . Typically low or even negative value materials for MRFs include glass , mixed paper and cartons .  They also should consider if the material is easy to separate and bale to sell for the needed revenue. For example, steel cans are easy to remove from the rest of the single stream recyclables via a magnet . Artificial Intelligence , robotics and optical scanners help address materials being missorted . Nonetheless, many MRFs do not have this kind of technology, nor the capital to purchase it . Environmental impact of recycling In addition to the economic impact of recycling, companies should consider the environmental impact that comes with how their packaging is recycled. The amount of energy saved from making a product with recycled material versus virgin material differs. With plastic and glass, it’s about a third . In contrast, aluminum cans and steel cans save 90 percent and 75 percent , respectively. A company making sure all its packaging is technically recyclable does little to address this problem of too much packaging that the U.S. recycling system cannot process economically and efficiently. Recycled content goals are certainly a step in the right direction toward building up domestic recycling markets and achieving the above environmental impact with greater displacement of virgin material. However, companies still should consider whether the materials in their packaging can loop numerous times. Plastic can be recycled only two or three times . Alternatively, glass and metal can recycle many more times as there is no loss in quality when they are recycled. When multiple loops from the same piece of material are considered , the environmental and economic impacts stack up . Packaging choice is critical to recycling system health The key to a thriving recycling system is either investing in the technology and infrastructure necessary such that all recyclable materials can be economically and efficiently recycled at scale or having more consumer goods companies choose packaging that recycles economically and efficiently in the current system. Neither is happening right now. Too much packaging dumped into the marketplace does not work in today’s recycling system. It’s worthless, multi-material, hard to separate and/or not easy to recycle into anything useful/recyclable. No wonder there are now calls for the chasing arrows symbol to be taken off all plastic packaging, and Greenpeace is suing Walmart for misleading recyclability labels on its plastic products and packaging. A company making sure all its packaging is technically recyclable does little to address this problem of too much packaging that the U.S. recycling system cannot process economically and efficiently. Companies need to go beyond technically “recyclable” in the sustainability metrics they use to choose their packaging . Potential alternative metrics include some percent of all the company’s packaging is above a certain value per ton, some percent of all the company’s packaging is primarily made of material that does not degrade during the recycling process and some percent of all the company’s packaging is primarily recycled into the same kind of packaging or other useful, easy to recycle products. There’s an opportunity for a company to be the first mover in next level recycling metrics and packaging choice. Once many companies make the shift, the recycling system will thrive and the economic and environmental impact from recycling will multiply.
