Biomass is a term for materials that come from plants and animals. An example of biomass is wood. Biomass is commonly used to produce energy.
Biomass such as wood chips, particular types of garbage, corn and even animal fats, can all be converted into energy. For example, burning a biomass releases energy as heat, which then can be stored. Biomass is also used to create biodiesel using vegetable oil and animal fats; whereas, ethanol is produced through the fermentation of corn and sugarcane. Using biomass as an energy source is a step to reduce the carbon footprint and build a more eco-friendly world.
