Polyesters are primarily made from petrochemical sources, specifically derived from fossil fuels like crude oil. The most common type of polyester, polyethylene terephthalate (PET), is produced through a reaction between ethylene glycol and terephthalic acid, both of which are synthesized from petroleum. Additionally, bio-based polyesters can be produced from renewable resources, such as plant-derived sugars, but traditional polyesters heavily rely on chemical processes involving fossil fuels.

Is polyster sustainable?
Did you mean POLYESTER, I suppose.It depends of the way it is made, of the production methods used by the factory.So there are sustainable polyester tissues and other non sustainable.From Wikipedia we get:Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polycarbonate and polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.
Is polyesters thermoplastic?
Polyesters are a group of organic polymers that contain the ester functional group in their main chain. Polyesters can be either thermoplastic or thermoset, depending on the rest of their structure, but the most common polyesters are thermoplastic.
What is polyester used to make?
Polyester is a category of polymers which contain the ester functional group in their main chain.

Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.Depending on the chemical structure, polyester can be a thermoplastic or thermoset; however, the most common polyesters are thermoplastics.

Medicine is mostly made out of plants, and plants are living organisms. There are few medicine containg glucose which is C6H12O6, there is also weed, marijuanna, these are a few chemicals which is quite famous used.
The cytoplasm of cells is made mostly of what?
The cytoplasm of cells is mostly made up of water, along with various salts, ions, and organic molecules such as proteins, carbohydrates, and lipids. It also contains cellular organelles, such as mitochondria, ribosomes, and the endoplasmic reticulum.

Pheromones, mostly.
It is safe to smoke filtered cigarettes?
No... filters are mostly made up of fiberglass and nylons. Although it catches a percent of the chemicals you maybe adding another substance or chemicals from the filter itself.
