Biofuels

Biofuels, also known as eco-fuels, refer generally to fuels made up of or made of organic matter, such as ethanol car fuel made from corn, or biodiesel made from recycled cooking oil. There are many types of substances that can be extracted from biofuels, such as corn, soybeans, flaxseed, rapeseed, sugarcane, coconut oil, kitchen cooking oil, etc. It is different from traditional fuels such as petroleum and belongs to renewable fuels. Although biofuels are renewable energy sources, there are many problems with crops that produce biofuels, such as pollution and food security, which have not yet been widely used globally.
