The production of biodegradable plastics is considered to be a tool to solve plastic pollution, especially a special tool to deal with the ecological and environmental problems of plastic food touching raw materials (such as disposable plastic straw). "It disappears automatically without solution" is his understanding and expectation.

The United Nations Environment Programme released a report entitled "biodegradable plastics and marine garbage: concern and harm to marine resources", calling for clearing up misunderstandings under the logo of "biodegradable plastics". The application of commodities marked as "biodegradable" is not easy to significantly reduce the amount of debris of plastics into the deep sea or reduce the physical and organic chemical risk of plastics to the composition of the deep sea. Food plastic packaging with "biodegradable" or "100% biodegradable" logo is very easy to be misunderstood by customers, which improves the frequency of arbitrary purchase and treatment, and aggravates the problem of plastic pollution.

Some marked biodegradable plastic bags can be used normally even if they are placed under various geographical environment standards for 3 years. The evaluated aerobic or biodegradable plastic bags did not mainly show a stronger dissolution effect than the basic plastic bags. The advanced European bioplastics Research Association in the industry questioned the reasonable characteristics of the scientific research and felt that the scientific research misunderstood the use value of biodegradable and compostable plastics.

Its effectiveness in solving plastic pollution has been debated. The reason is that apart from the hazards of unclear current policies, unhealthy standards and controversial scientific research, the hazards of people and fields to biodegradable plastics are also very important because of unclear definitions and confusion. Misuse, misuse of biodegradable labels, and even false publicity. Some typical misconceptions are: making bio based plastics equivalent to biodegradable plastics. Consider biodegradability as biodegradable. Biodegradation in the case of industrial production of compost is considered to be biodegradable in the environment.
