Chemical recycling
Chemical recycling uses chemical processes to convert plastic waste into monomers, feedstocks, fuels, or other chemical products. Applying Chemical recycling requires a stated material pathway, lifecycle stage, retained function, waste status, and end-of-life route. Those choices determine how Chemical recycling can be compared or acted upon.
In simple terms
In practical use, Chemical recycling uses chemical processes to convert plastic waste into monomers, feedstocks, fuels, or other chemical products. For Chemical recycling, its suitability depends on local conditions, implementation quality, assigned responsibility, and monitored outcomes within a declared material pathway, lifecycle stage, retained function, waste status, and end-of-life route. Chemical recycling connects with Recycling and Waste hierarchy; each can affect its application without sharing its definition. The candidate link between Chemical recycling and Closed-loop supply chain remains a separate expansion question supported here by Organisation for Economic Co-operation and Development.
Why it matters
Chemical recycling matters because decisions about it determine which lifecycle route is preferred, how much function or material value is retained, and where responsibility ends. A defensible use of Chemical recycling therefore exposes its boundary, method, evidence, responsible actor, and uncertainty before a conclusion is accepted. That discipline keeps Recycling and Waste hierarchy from being treated as proof of Chemical recycling when their criteria, scope, or results differ.
Example
A product and materials team evaluates Chemical recycling for a defined decision and records the relevant material pathway, lifecycle stage, retained function, waste status, and end-of-life route. For Chemical recycling, the team uses cited material from Organisation for Economic Co-operation and Development to plan the intervention, assign responsibility, and monitor outcomes, documenting the period, data, assumptions, and comparison with Recycling. It treats Waste hierarchy and Closed-loop supply chain as separate questions rather than proxies for Chemical recycling.
How it differs
Recycling
Chemical recycling is a practice or intervention; Recycling has a different function. Evidence for Recycling does not establish Chemical recycling unless both sets of applicable criteria are met.
