oil
Crude oil.
No. Plastics are mostly made from fossil fuel oil, so they're not renewable and they're not natural either, but man-made.
Polyester is a non-renewable resource. Polyester is made from plastics, plastic is made from oil. Oil is a non-renewable resource, as the world is running out of oil already and there is no more being created.
Yes
Plastics, and has been since 1976
Crude oil>ethane/propane>ethylene/propylene>reacted fluff>formed in to pellets via extrusion process. (short version)
Many plastics are.
it helps conserve more natural resource
mining is Nevada's major resource
Some of the problems are: 1) reduction of non-renewable resources (in the most common case, plastics are a petrochemical product...made from hydrocarbons, which are made from refined crude oil, which is a non-renewable resource); 2) (polution) - when not recycled, plastics create a lot of waste (see large masses of plastic floating around our oceans); 3) (pollution) - some plastics also form toxic substances when they are broken down
The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
A backpack is generally considered a nonrenewable resource because it is made from materials such as synthetic fabrics, plastics, and metals, which are derived from finite natural resources. Once these materials are used and the backpack is discarded, they do not regenerate quickly or easily. However, if the backpack is made from sustainable materials or is designed for longevity and recyclability, it may have a lesser environmental impact.
