EPA Approved a Fuel Ingredient Even Though It Could Cause Cancer in Every Person
- PaulHoule 3y agoI have seen this story repeated in many media outlets but no mention of what this ingredient actually is.
- ano-ther 3y agoAgree it’s odd. Must be one of these, which don’t really have a name (link from the article): https://www.documentcloud.org/documents/23886219-integrated-risk-assessment-for-chevron-waste-plastic-fuels https://www.documentcloud.org/documents/23886219-integrated-... > SUMMARY 1.1 Background Chevron Corporation submitted premanufacture notices (PMN) for eighteen waste plastic fuel streams, P-21-0144 through 0150, P-21-0152 through, and P-21-0160 through 0163). These new chemical substances (NCSs) are complex mixtures. They are manufactured concurrently with petroleum streams and have identical composition; the only difference is that the feedstocks are waste plastic-based sources rather than petroleum-based sources. The intended uses are as fuels, fuel components, and chemical intermediates or refinery feedstocks
- PaulHoule 3y ago... most the interesting stuff in that document is redacted! It seems the substance is a mixture of pyrolysis compounds and they're assuming the worst case cancer risk is if 100% of the material is the most carcinogenic constitutent possible, which might be something like https://en.wikipedia.org/wiki/Benzo(a)pyrene https://en.wikipedia.org/wiki/Benzo(a)pyrene which is definitely worse than it really is.
