Mass Balance Attribution Carries Most Reported Bio Content
A steam cracker cannot segregate a modest renewable feedstock stream through equipment designed for continuous operation, so the renewable content gets allocated to specific output volumes under chain of custody certification instead. Roughly 58% of automotive bio content moves this way, and the polymer arriving at the moulder is chemically identical to the fossil grade. For an OEM this is enormously convenient: renewable content gets reported without requalifying a material, retooling a part, or telling the supplier anything has changed at all. The claim rests on the audit rather than on the component.
