It is made of starch raw materials proposed by renewable plant resources (such as corn, cassava, etc.). PLA is recycled in daily life. The biodegradable soup bowl is suitable for family meals, restaurant utensils, etc. Composting can be degraded into carbon dioxide and water in 30 days, which plays an important role in environmental protection.
