i dont know what plastic is made of and will we ever run out.
plastic is made of a **** load of cellulose fibers. They use petroleum one of the main materials needed to make plastic.
. Petroleum is drilled and transported to a refinery. 2. Crude oil and natural gas are refined into ethane, propane, hundreds of other petrochemical products and, of course, fuel for your car. 3. Ethane and propane are cracked into ethylene and propylene, using high-temperature furnaces. 4. Catalyst is combined with ethylene or propylene in a reactor, resulting in fluff, a powdered material (polymer) resembling laundry detergent. 5. Fluff is combined with additives in a continuous blender. 6. Polymer is fed to an extruder where it is melted. 7. Melted plastic is cooled then fed to a pelletizer that cuts the product into small pellets. 8. Pellets are shipped to customers.
till those days plastics have been created from Petroleum. Then a pair of years in the past Dow chemical presented a clean plastic created from corn. that's a bioplastic. there's a great form of experimentation happening interior the study of such techniques. you would be listening to plenty approximately bioplastics as they are seen green techniques. you will see them on packaging and such! Bioplastics are created from plant sources inclusive of hemp oil, soy bean oil, corn starch, and now corn. How? The petrochemical resin is replaced by potential of a vegetable or animal resin.
Plastics are made out of water-resistant polymers. Most of them are made of petroleum derivatives, and some are made out of plant by-products. It's not that we will eventually run out of oil, it's that oil will be too expensive to obtain and therefore petroleum-derived plastics will cease to be cheap. Many of the plant-derived ones don't work as well for certain applications (bottles of liquid, industrial applications), but they will be improved as time goes on and may eventually be suitable for these purposes. The biggest issue is that plastics are not particularly recyclable. Some of them are, but many of them aren't. And since plastics tend to absorb some of the stuff they're in contact with (cola, chemicals, whatever), manufacturers are often reluctant to use recycled plastic for most applications and they can't be used for food storage. Recycling won't be able to solve the problem of petroleum getting prohibitively expensive over the next decades. Of course, we may always discover some other really good cheap source of oil and not have to worry about this for another seventy years.
Mostly oil, secondly coal and thirdly trees!
