[QUOTE="user 4386, post: 653625, member: 4386"] Although it presently comes mostly from petroleum refining, there are large deposits that are already bitumen. It is not readily biodegradeable, so goes to landfill or is recycled. I doubt that it is considered a significant part of the carbon footprint. What about plastics? I think the dominant feed is natural gas (and because of heavy EV batteries, EVs contain up to 250 kg of plastic to keep them light). Some is made from coal and petroleum derivatives and a small amount from plants. They also don't figure much in any carbon footprint, but an estimated one third is used in packaging and the immense volume annually creates other problems. Life wasn't meant to be easy.... [/QUOTE]
