Chemical and mechanical recyclers must work together to achieve circularity for the plastics supply chain, according to Martyn Tickner, chief advisor/circular solutions at the European Alliance to End Plastic Waste, in a speech Oct. 15 at the 2024 Recycling Expo in London, as per Chemweek.
Tickner reflected in his speech on themes and pressures that have driven conditions in mechanically and chemically recycled markets throughout 2024, reflecting broader market player concerns, but also consensus within the industry about the path toward increased adoption and commoditization.
Tickner noted that “mechanical recycling remains the preferred option” for recyclers and industry players due to a “lower carbon footprint” and “lower cost” than its chemical counterpart.
Despite this preference, Tickner emphasized that chemical recycling was still necessary and stressed that “the gap is going to close” between the divergence in utility between both segments due to a need to meet the EU food industry’s plastic waste targets.
To handle plastic waste, including food packaging, chemical recycling methods such as pyrolysis, where waste plastic is converted into pyoil, or depolymerization, where polymers are liquified back into their monomer building blocks. According to sources, chemical recycling is more effective in this application, offering less variance in output quality than its mechanical counterpart.
For traditional technologies, Tickner explained that advanced mechanical recycling would be required to keep up with EU mandates and ensuring effectiveness in providing the minimum amount of material needed to meet inclusion targets. Under advanced mechanical recycling methods, material undergoes a more stringent sorting and processing procedure than in simple mechanical processes, allowing for higher and more consistent output quality.
Tickner said that products converted through this method had 35% more post-consumer recycled material, in line with European Packaging and Packaging Waste Regulation inclusion requirements for non-polyethylene terephthalate (PET) recycled materials. He added that, through this process, mechanical recycling could yield higher-quality products, which by the start of such EU requirements in 2030 will “command much higher pricing,” increasing incentives for some recyclers.
Tickner’s bottom line was that mechanical and chemical recycling technologies complement each other and both are necessary to create a closed loop on plastics in Europe.
Competitiveness concerns hamper wider conditions
In the wider market, traders have said that brands have been slowing down the amount of recycled material they use ahead of EU regulations due to a lack of affordability and generally weak macroeconomic conditions that have hampered consumption of polymers in 2024.
This has led to consumer cost competitiveness in favor of virgin materials, which Tickner also addressed during his speech, saying that “virgin polymer is very cheap,” which has counteracted the short-term impact of “regulations [which are] not there yet.”
Such dynamics have been a critical force in undercutting the commoditization of recycled and sustainable materials in the European market in 2024, with consumers favoring the use of cost-competitive virgin material against a weak macroeconomic backdrop.
Attendees at the event echoed these concerns, with a recycler saying that higher prices for recycled material continued to clip buyer appetite.
Natural recycled polypropylene (PP) pellet pricing has averaged a €636.67 per metric ton premium to virgin homopolymer spot values in the fourth quarter to date, up 12% on the quarter, Platts data showed, as both import and domestic supply have lengthened in the latter market.
Looking ahead, Tickner was optimistic in his expectations for the development of European circularity, noting that “end market demand is addressed by PPWR.” He noted a road map for broader commoditization from the recycled PET segment, saying that the sector “is an example of how a recycled market can look ... we are not there yet with most other polymers.”
Another conference attendee said that r-PET saw better purchasing demand than adjacent materials, such as recycled high-density polyethylene (HDPE), for packaging due to legislative packaging requirements, which is an end-user industry that PET is strongly utilized in.
A lack of industry-adopted specifications for most recycled materials was also highlighted as a critical hurdle for commoditization, with Tickner saying that “it is necessary to establish quality specifications ... starting with the end product rather than the feedstock.”
A broker expressed similar sentiment, attributing large variations in price for recycled materials to the lack of standardization between grades. They argued that this makes trading conditions more difficult for both buyers and sellers.
“Buyers are unsure of if they are being given a reasonable price, and the recyclers/bale producers are not sure where to price their products,” the broker said.
