In its broad meaning, biomass is a kindof organic matter produced by the photosynthesis ofplants, which is not only renewable, but also containsplentiful energy. It is estimated by biologists that thetotal grown biomass every year on Earth is about140～180 billion tons (dry weight), which is 10 timesthe total energy consumption in today's world.Thereis an abundance of biomass energy resources in China.
