Wang Badan, an expert, suggested that burning straw and returning it to the fields should be prohibited. In his view, burning straw not only pollutes the air, but also has many security risks. Professor Zhu Qizhen pointed out that straw can be used as a kind of biomass energy. Biomass energy is a kind of renewable energy, which has the advantages of green, environmental protection and sustainability. Converting straw into biomass energy can not only reduce the generation of waste, but also increase the income source of farmers.
