Finc is a modernized agricultural factory, obtaining the Green Food certificate. During our whole production of mushrooms, we do not add any chemistry materials, fertilizer. The only thing that we add during the growth of mushrooms is just a little clear water in the process of Fungi Scratching The raw materials that we use are the leftovers from surrounding enterprises, such as sawdust, which are the waste after the production of other enterprises. After being purchased by our company, their waste disposal problem are solve by us . At the same time, the straw used in our production of raw materials also eliminates the procedure that local people have to burn the straw after harvesting grain. When the mushroom becomes mature, the remaining culture medium after harvest can also be used to process and produce organic fertilizer, feeds and biogas. It can promote the reuse of agricultural waste, forming a circular agriculture that turns waste into treasure in the edible fungus industry. In this way it also realizes diversified value-added and purifies the environment.
