Biodegradable Plastic Bags Have To "Grab Food" With Humans?
Biodegradable plastic bag raw materials are starches extracted from plants such as corn. Will it cause biodegradable plastic bags and humans to “grab” food?
The starch obtained by the refining of the starch is made into a biodegradable plastic bag. Ordinary plastic bags are made of petroleum as a raw material. Their molecular structure is very stubborn. They are buried in the soil for several hundred years without degradation. The biodegradable plastic bags are eaten by microorganisms in the high temperature and high humidity composting environment for about 6 months. Light turns into organic fertilizer. The organic fertilizer formed by the biodegradable plastic bag has no pollution to the soil.
Starch can be extracted from a variety of plants such as corn, sweet potatoes, and potatoes. The source is very wide. China is also a big corn producer with the second largest output in the world. Compared with the huge supply, the social consumption capacity is insufficient, and the consumption of the environmental protection industry is very limited. In fact, it is not new to use corn, cassava and other foods for industrial production. For example, the paper industry has already used starch as one of the industrial raw materials.
