"The one-in-four lifetime cancer risk from breathing the emissions from the Chevron jet fuel is higher even than the lifetime risk of lung cancer for current smokers.

... Throwe said the existing testing and monitoring requirements for refineries couldn’t capture the pollution from these new plastic-based fuels because the rules were written before these chemicals existed.

... In her three decades at the EPA, Doa had never seen a chemical with that high a cancer risk that the agency allowed to be released into a community without restrictions.

“The only requirement seems to be just to use the chemicals as fuel and have the workers wear gloves,” she said.

While companies have made fuels from discarded plastics before, this EPA program gives them the same administrative break that renewable fuels receive: a dedicated EPA team that combines the usual six regulatory assessments into a single report.

The irony is that Congress created the Renewable Fuel Standard Program, which this initiative was meant to support, to reduce greenhouse gas emissions and boost the production of renewable fuels. Truly renewable energy sources can be regenerated in a short period of time, such as plants or algae. While there is significant debate about whether ethanol, which is made from corn, and other plant-based renewable fuels are really better for the environment than fossil fuels, there is no question that plastics are not renewable and that their production and conversion into fuel releases climate-harming pollution.

... The idea of creating fuel from plastic offers the comforting sense that plastics are sustainable. But the release of cancer-causing pollution is just one of several significant problems that have plagued attempts to convert discarded plastic into new things. One recent study by scientists from the Department of Energy found that the economic and environmental costs of turning old plastic into new using a process called pyrolysis were 10 to 100 times higher than those of making new plastics from fossil fuels. The lead author said similar issues plague the use of this process to create fuels from plastics."
