Biomass Energy： An Indispensab Link in the Circular Economy

BIOMASS energy is currently the fourth largest energy source in the world, exceeded only by coal, petroleumand natural gas. It can be obtained from plants, animal and human excrement, garbage and organic wastewater. The importance of developing green energy, particularly its development from waste materials, is ever more widely recognized, so in China, projects involving self-contained, consumer-producer energy loops are encouraged.
