Biodegradable materials: through respiration or biochemistry, degradation of natural microorganisms such as bacteria, and ultimately decomposition into carbon dioxide and water;
 

Environmentally-decomposed substances: substances decomposed under natural conditions, such as light, heat, water, contaminant compounds, microorganisms, insects, mechanical forces, etc.
 

The potential advantage of developing biodegradable plastics is that starch is biodegradable in a variety of environments; The starch molecules in the plastic are degraded or ash, which produces carbon dioxide gas without polluting the soil and air. The mechanical properties of plastic materials can be achieved by using proper process to make starch thermoplastic. Starch is a kind of renewable resources, sustainable development, development of starch is beneficial to rural economic development.
 

It is worth mentioning that most domestic production of starch plastics are filled with starch plastics, or adding a certain proportion of starch to the biodegradable polymer materials, starch biodegradable leads to overall collapse, the physical properties of the material of the base exposure cause oxidative decomposition, PE, PVC and other residues cannot decompose, residues in the soil, Accrual over a long period of time causes pollution naturally, because this product is listed as the elimination of products abroad.
