of the material from which it is made. Indeed, the sustainability benefits of drop-in biobased plastics occur at the beginning of the material life cycle, but still, when manufactured, their structure is identical to their fossil-based counterparts. Therefore, these plastics, known as 'drop-ins', are not biodegradable, and should be recycled in existing recycling systems.

In this regard, biodegradability does not support circularity unless biodegradable materials
