During the wheat harvest season each year, a dedicated person goes to the field to be responsible for baling straw, and at the same time, farmers are given a certain purchase fee for each acre of waste wheat straw. These straws are "swallowed" and compacted by a pick-up and baler, then bundled and "spit out", and then loaded onto a transport truck by a bale grabber, and finally sold to a power plant for secondary use as fuel for power generation. In this way, the wheat straw changed from a disgusting rubbish to a "sweet rice cake".
Through the reuse of discarded wheat straw, not only the ridges of the fields are tidied, but the management of the autumn crops is convenient, and most importantly, the rural environment has become more beautiful and the income of farmers has increased. Zhang Jianlong, director of the State Forestry and Grassland Administration, said during the National Two Sessions this year that it is necessary to vigorously develop agricultural and forestry biomass energy to maintain national energy security. "The development of biomass energy must be regarded as an important strategy, and the conversion of agricultural and forestry wastes into biomass oil is an important part of it, and the cellulose, hemicellulose and lignin in the biomass composition can be used for value-added and efficient use."
