Biomass energy from plant waste is important for renewable energy in China. The country has a lot of biomass waste that can be used for energy, but it's not being fully utilized. Different technologies like burning, fermentation, and gasification can turn this waste into useful energy sources like power, fuel, and fertilizer. By developing these technologies, China can reduce its reliance on non-renewable energy and help the environment. The future of biomass energy in China looks promising with the potential for more efficient and widespread use of these technologies.
