The first modern plastics were made in the 1930s. Most clear plastic starts out as thick, black oil. That plastic coating inside a pan begins as natural gas. Over the years, hundreds of different plastics have been developed. Some are hard and strong. Some are soft and bendable. Some are...
Plastic does not grow in nature. It is made by mixing certain things together. We call it a produced or manufactured material. Plastic was first made in the 1860s from plants, such as wood and cotton. That plastic was soft and burned easily. The first moder...

The plastic value chain is complex and touches upon several business sectors along its way. The majority of plastics are produced from fossil hydrocarbons, traditionally from naphtha—a by-product from refining crude oil into fuels—or from natural gas condensates such as propane and ethane [17]....
According to Chen Gang, chairman of Polyrocks Chemical, Polye's parent firm, the bag's raw material is modified Polyvinyl Alcohol, or PVA, which comes from natural gas or calcium carbide. "PVA bags dissolve in water in minutes so they won't choke the marine animals. The solution will not...

More than 99% of plastic is made from fossil fuels, like ethane that is a byproduct of the fracking of natural gas. At every stage in its lifestyle, from its extraction, transport, manufacturing into pellets, use in products and eventual disposal, plastic intensively emits carbon dioxide ...
(due to relatively high land availability), low energy prices (due to low natural gas prices), and public opinion. There are also concerns about emissions associated with this process. Countries that have achieved near-total diversion of plastic from landfill send significant quantities of pla...
from an estimated mean of 0.078 [0.058, 0.105] μg C L−1hr−1under the control treatment to 0.178 [0.132, 0.240] μg C L−1hr−1under the plastic treatment. We also found that bacterial growth was more efficient in the presence of plastic leachate than when only natural lake ...
