1. Composting degradation: Under composting degradation condition, PLA products could be 100% biodegradable within 180 days, and the final products of degradation were carbon dioxide and water. Composting condition is as follows:- Temperature 58+/-2 degree Celsius- Humidity 98% 3)With the action of micro-organism/p>
2. Landfill degradation: Landfill conditions are different from composting conditions, so the degradation rate of PLA products is relatively slow, which generally takes 2-5 years. However, the degradation products do not pollute groundwater, damage plant growth, or waste cultivated land.
3. Incineration: The combustion value of PLA products is small, and the complete combustion products are carbon dioxide and water, which do not pollute the air.
