El Dorado of Chemical Recycling, State of play and policy challenges
Over the last few years the concept of chemical recycling has been promoted by industry as a potential solution to help curb plastic pollution and waste management as a whole. This Zero Waste Europe report looks into the knowledge available as well as the state of implementation of such technologies in the European context.
Mechanical recycling is a mature industrial process, well established and expanding in Europe. Plastics cannot however be endlessly recycled mechanically without reducing their properties and quality. Besides, not all plastic types can be mechanically recycled. These limits set challenges for plastics recycling and show the need for significant improvements in the end-of-life management of plastics.
Since decades, innovators test gasification and pyrolysis for alternatives to waste to energy incineration with very limited results due to the energy balance and the environmental impact. In general, more information is needed about the environmental performance of chemical recycling technologies, as this industry is in its infancy and most plants are mere pilots. The roll-out of such technologies at industrial scale can only be expected from 2025-2030, an important factor when planning the transition to a Circular Economy and wider decarbonisation.
The right policy framework must accommodate chemical recycling as complementary to mechanical recycling while ensuring that carbon stays in the plastic, thus not being released into the environment. Therefore, allowing plastic to fuels to be considered chemical recycling risks creating a loophole in EU Climate and Circular Economy legislation.
