Casein plastic is biodegradable. It is cheaper to produce than plastics derived from petroleum. The diagram shows how the ingredients of casein plastic (cow's milk and vinegar) are obtained. Some of the trade-offs involved in the production of each ingredient are also shown. Information
A diagram. Short description, A diagram.,Long description,
The diagram shows that processing cow's milk and vinegar produces casein plastic.

To produce the cow's milk, cows are raised on farms. Some trade-offs of this are it requires equipment to raise and house cows, it requires energy to feed cows, and the farm waste can pollute the environment.
To produce the vinegar, corn is grown and harvested. Some trade-offs of this are its growth requires water, the farm runoff and harvesting can cause pollution, and harvesting requires equipment and energy.
Vinegar is made from fermentation of corn. Some trade-offs of this are processing can cause pollution, the process produces waste, and the process requires energy.
