Biomasse refers to organic materials derived from plants and animals that can be used as a source of energy. This includes materials like wood, agricultural crops, and animal waste. Biomass can be converted into biofuels, such as ethanol and biodiesel, which can replace fossil fuels in various applications, including transportation and heating. Using biomass for energy has several benefits, including reducing greenhouse gas emissions and promoting sustainable energy practices. It can help manage waste by repurposing materials that would otherwise be discarded. However, the production of biomass must be managed carefully to avoid negative impacts on food supply and ecosystems.
