Synthetic Materials: 8B by Lindsay Stewart https://padlet.com/lstewart15/4sqe8iyg28w4 Made with joy en-us 2016-10-25 18:07:43 UTC 2026-03-21 14:10:30 UTC hello@padlet.com Rayon https://padlet.com/lstewart15/4sqe8iyg28w4/wish/133385422 How it's made:
Rayon is made by purified cellulose which are put into sodium hydroxide. The sheets are dried and turned into crumbs. they are then turned into a liquid carbon disulfide. They are then put into a viscose solution which turns into a string of fibers. They finally bathe it in acid and turn it into yarn.
Impact on society:
It's made from wood pulp, however, for the wood pulp to become a fabric, it's treated with hazardous chemicals.

In this reaction, two or more molecules combine to make a large molecule whose structure repeats throughout its length. Polyester fibers can form very long molecules that are very stable and strong.

Polyester is used to make PET bottles and nylon rope because of its strength. In the 1970, polyester suits were in strong demand because it was appreciated for its strength and comfortness.

Impact on society: It is non-biodegradable and and its manufacture create Nitrous Oxide with is 310 times more potent than carbon dioxide.  It also needs a lot of water to manufacture and as well as a terrible lubricant.

-It made life easier and safer but it has a bad impact on the environment and human health

Petroleum fuels airplanes, cars, and trucks, as well as heats homes and makes medicines and plastics. It's also used in plastic. Society has come to rely on petroleum for a lot of things. However,  drilling for oil can disturb land and marine ecosystems.

*Note* This video explains how oil and gas is extracted, however fossil fuels have a fairly similar process]]> 2016-10-26 16:24:15 UTC https://padlet.com/lstewart15/4sqe8iyg28w4/wish/133387502 Biofuel https://padlet.com/lstewart15/4sqe8iyg28w4/wish/133387590 How is it made?
The solar energy is captured by the crops using photosynthesis and it is stored in the plants cells .It is used for biofuel production and then is is used as feedstock.

Effect on society: 
Biofuel is the natural version of previous fuel and is used to power cars and other vehicles.

The soda reduces the sand's melting point, which helps to save energy during manufacture, but it has an unfortunate drawback: it produces a kind of glass that would dissolve in water! The limestone is added to stop that happening. The end-product is called soda-lime-silica glass.
Effect on Society:
The major environmental impact of glass production is caused by atmospheric emissions from melting activities:
