INSIGHT by Zero Waste Europe
In a new study launched this afternoon, Zero Waste Europe (ZWE) assesses the consequences of different approaches to allocating recycled content in plastic. The study proves that proportional allocation has the lowest impact on the level-playing field and the largest potential environmental benefits.
Officially launched and presented during a Zero Waste Live! Webinar instalment, the “Impacts of allocation rules chemical recycling – impact on environment and maximum circularity of plastics” study calculated the impact of the different allocation rules regarding the environment, material circularity and level playing field in the recycling landscape.
〉Proportional allocation leads to greater transparency in the plastic recycling market, as it reduces ambiguity about recycled content in plastic outputs.
〉A larger share of thermo-chemical technologies results in lower environmental benefits and reduced maximum recycling rates.
〉Proportional allocation reduces the risk of scenarios where long-loop chemical recycling dominates. In such a scenario, the CO2 benefits of plastics recycling could be up to 9 Mtonnes lower than in a scenario with more mechanical recycling.
〉If the European Commission chooses polymers-only or fuel-exempt allocation, a cap on chemical recycling may be necessary to prevent it from outcompeting mechanical recycling. The study suggests that a cap of 12,5 to 25% on chemical recovery, as proposed in the Dutch Transition Agenda, could be a suitable option.
“Using the mass-balance chain of custody for recycled content claims must always be a last resort and based on proportional allocation. Otherwise, these claims will promote greenwashing, and undermine the circular economy and climate agenda. Chemical recovery technologies, i.e. pyrolysis and gasification, should be limited to the bare minimum to avoid a lock-in effect similar to incineration”.
-Lauriane Veillard, ZWE’s Chemical Recycling and Plastic-to-Fuel Policy Officer
ZWE urges the European Commission to take into account the study’s findings on allocation rules and recycled content targets for plastics in their upcoming files:
〉Use ‘batch level’ mass balance to determine recycled content, so that it is clear how much recycled material is in the final product.
〉Use proportional allocation to evenly allocate the recycled content to output products when using mass balance (instead of allocating it arbitrarily).
〉Consider capping chemical recovery to avoid it overtaking mechanical recycling if polymers-only or fuel-exempt models are used.
〉Implement regulation to ensure that mechanical remains the primary recycling option for maximum CO2 reduction and circularity score.
