The “completely biodegradable” plastic products produced in Hainan, China, are processed from raw materials such as starch granules produced by cassava processing and it reached food grade.

According to reports, Hainan's largest fully degradable plastics project is expected to have an annual output value of more than 50 million yuan, an annual tax revenue of about 6 million yuan, the scale will continue to expand, to achieve biological resources, use pollution-free, pollution reduction. After the cassava starch is turned into a biodegradable plastic project, it can reduce the concentrated emission of carbon dioxide and replace the polluted non-degradable plastics, extending a more reasonable and efficient industrial chain, and the by-product waste gas can also be Utilization has improved economic and social benefits.

According to statistics, Hainan currently uses about 1.5 million plastic bags per day, of which more than 90% are non-degradable plastic products. Non-degradable plastic products are discarded at will, posing serious potential hazards to the ecological environment. Incineration of discarded plastic products produces harmful gas "dioxin", which seriously pollutes the air and harms human health. After the ordinary plastic enters the soil, it takes at least 15 months to decompose, which harms the growth of plants and crops. In order to reduce the plastic waste in Hainan, the Hainan Provincial Ecological Research Institute began to find solutions and technologies in 2011, and finally introduced the production technology project of “cassava starch into biodegradable plastic”.
