Final answer:
Biodiesel is produced from recycled cooking oil, animal fats, and other sources and is a sustainable biofuel alternative to traditional diesel.
Step-by-step explanation:
The product made from recycled cooking oil, animal fat, and other sources is biodiesel. Biodiesel is a type of biofuel that is designed to be used in standard diesel engines and is thus a sustainable alternative to traditional petroleum diesel. Biodiesel can be manufactured from vegetable oils, animal fats, or recycled greases. It can be used on its own or blended with petroleum diesel. One of the main advantages of biodiesel is that it is environmentally friendly; it typically produces fewer pollutants and greenhouse gases than petroleum-based diesel. The process of making biodiesel involves the chemical reaction known as transesterification, where glycerin is separated from the fat or vegetable oil, leaving behind methyl esters (biodiesel) and glycerin (a byproduct which can be used in other industries).
