It is good to have many feedstocks.
"Crude oil" is "oil" - petroleum. Plastics such as polyethylene (food containers) and polystyrene(general plastics and styrofoam) are made from fractions of crude oil. Polycarbonate plastics are made indirectly through the production of phosgene and its use to make acetone and bisphenol-A.
the plastics are cheap, durable and easily made into intricate shapes.
Many parapharmaceutical products are made from plastics.
- Some plastics made from starch are biodegradable- Another bio-oxodegradable plastics contain a catalyst ( as iron oxide) which improve the degradation in contact with oxygen.Generally biodegradable plastics are as foils not containers.

All plastics are a by product of crude oil.
Crude oil.
Most plastics are made from crude oil derivatives.
Crude oil.
Only about 15% of the crude oil is made into jp54 but the rest of it usually is made into other things such different types of plastics and such
Plastics can be recycled over and over, whether they are made from crude fossil fuel oil, or renewable vegetable oil. So in this sense they are sustainable. The earth has a limited supply of crude oil, but when that runs out there will still be some fossil fuel plastics to be recycled.

None, because plastics are made from hydrocarbons, which are obtained from the refinement of crude oil. Plastic is not made from trees.

Plastics such as polyethylene (food containers) and polystyrene (general plastics and styrofoam) are made from fractions of crude oil (petroleum). Polycarbonate plastics are made indirectly through the production of phosgene and its use to make acetone and bisphenol-A.
Polymers are not made into crude oil. Crude oil is made into polymers.
