Degradable plastics are eco-friendly and serve as a sustainable alternative to traditional petroleum-based plastics. They are classified by degradation type into biodegradable plastics, compostable plastics, photodegradable plastics and thermo-oxidative degradable plastics. Evaluating degradability through biodegradation, composting degradation, photodegradation and thermo-oxidative degradation can directly reflect the degradation performance of plastics under natural conditions. We provide one-stop testing and analysis services for degradable plastics, helping enterprises adapt to industrial changes effectively.

Service Background
Discarded traditional plastic waste causes severe environmental pollution. The resulting "white pollution" is recognized by the United Nations as one of the major global environmental issues. Landfill disposal occupies land resources, while incineration leads to air pollution. The replacement of traditional plastics with degradable plastics is a key solution to these environmental problems.
Europe has issued regulations on packaging and organic waste, together with the standard EN 13432 for compostable plastics. In the United States, relevant institutions have formulated ASTM D6400 for environmentally degradable materials. Meanwhile, countries worldwide including Australia, Japan, Rwanda and Kenya have rolled out relevant regulatory requirements.
In January 2020, China’s authorities issued policies to strengthen plastic pollution control, clarifying timetables for the prohibition and restriction of single-use non-degradable plastics. By the end of 2020, production, sales and usage of non-degradable plastic products were restricted in key regions and industries. This policy greatly impacts the plastics sector and accelerates the large-scale application of degradable materials across industries. We offer one-stop degradable plastic testing solutions to support enterprises in responding to industrial upgrading and regulatory updates.
