Present Utilization Conditions of Waste Agricultural and Forestry Fiber in China

Abstract

In 2016, the amount of waste agricultural and forestry fibers is 2.02 billion tons in China. Among them, 1.078 billion tons belong to waste agricultural fibers and 0.924 billion tons belong to waste forestry fibers. Moreover, there is a big developing potential of agricultural and forestry fibers in China since the area of forest are quite big. There are 44.03 million hectares of suitable forest and 7.1 million hectares of non-stumpage forest. If 20% of these lands is used to grow energy plants, the production of biomass can reach 0.1 billion tons with the expectation that one hectare of land can produce 10 tons energy plants. Energy storage of these plants is equal to that of 50 million tons of standard coal. There are also 76.49 million hectares of marginal land resources. If 20% of these lands is used to grow energy plants, the production of biomass can reach 0.152 billion tons with the expectation that one hectare of land can produce 10 tons energy plants. Energy storage of these plants is equal to that of 76 million tons of standard coal [1-3].
