Hainan’s new client, Nanhai Net, Nanguo Metropolis Daily News on December 4 (reporter Huang Ting and intern Wang Chunying) Hainan will ban plastics from December 1. Biodegradable plastic products will gradually replace traditional plastic products and improve biodegradable plastics. The ability to inspect products is critical to the source. The reporter learned from the Hainan Provincial Product Quality Supervision and Inspection Institute that in September this year, the institute successfully passed the qualification accreditation extension review of the provincial inspection and testing agency and obtained the qualification of biodegradability test, filling the gap in Hainan related testing technology.

The laboratory has carried out inspections and tests such as biodegradable plastic shopping bags.
Fully biodegradable plastics are caused by the action of microorganisms existing in nature under natural conditions such as soil and / or sand, or under specific conditions (such as composting conditions or anaerobic digestion conditions or in water-soluble media) . They degrade and eventually degrade into carbon dioxide or methane, water and mineralized inorganic salts of the elements it contains, and a new type of plastic. Fully biodegradable plastics do not contain non-biodegradable components and can be completely decomposed by microorganisms without leaving residues, making them more environmentally friendly.
A complete ban on plastics requires the support of standards and testing technologies for all biodegradable plastics. To do a good job banning plastics, our province planned ahead. On September 26, 2019, the Hainan Provincial Institute of Quality Inspection requested the establishment of the Hainan Provincial Technical Committee for Standardization of Biomaterials and Degradable Products, which is primarily responsible for the standardization of biological materials and degradable products. . At the same time, the Standards Committee formulated the framework for the complete biodegradable standards system and determined a three-year plan for standards development.
In 2020, the Hainan Provincial Quality Supervision and Inspection Institute issued the “Research Report on the Standard System for Fully Biodegradable Plastics Industry in Hainan”, and the “General Technical Requirements for Fully Biodegradable Plastic Products” were implemented the Hainan provincial local standards on July 1 this year. Two local standards, including the Rapid Detection Method for Degradable Components in Fully Biodegradable Plastic Products and the Rapid Detection Method for Fully Biodegradable Plastic Products Based on Electronic Monitoring, Spectral Fingerprints, have also passed expert review to form a draft for its approval, which will be used for the rapid detection of total biodegradability throughout the country. Leader in setting standards.
In September 2020, Hainan Provincial Quality Supervision and Inspection Institute successfully passed the provincial inspection and testing agency’s qualification accreditation extension review and obtained the qualification for biodegradability testing. At present, the laboratory has the capacity to detect heavy metals in biodegradable plastic products, discoloration experiments, potassium permanganate consumption, total migration, physical properties, biodegradability and other elements, it has already made biodegradable plastic bags and biodegradable garbage. Inspection and testing of bags and other fully biodegradable materials and products.
“Previously, to perform biodegradability tests, samples have to be sent to Beijing, Shanghai, Guangdong and other places.” According to Zhao Hongliang, Deputy Director of the Chemical Inspection Office of the Hainan Product Quality Supervision and Inspection Institute, the Hainan Quality Inspection Institute carried out biodegradability tests Fills the technical gap in the detection of biodegradable materials in our province, and it is of great importance to improve the detection capacity and quality of biodegradable plastic products.
Fully biodegradable plastic products must request an electronic supervision code for their commercialization.
Zhao Hongliang introduced that the biodegradability test cycle of fully biodegradable plastic products is long. It usually takes 45-180 days to test a sample. Currently, more than 20 manufacturers’ products are being tested.
For biodegradable plastic products whose biodegradability meets the requirements of the standard, producers and operators reportedly request an electronic supervision code through the Hainan Province Biodegradable Plastic Products Information Platform, and print it on the finished product, so that it can be put on the market. Consumers just need to scan the code with a key to query the regulatory code, check the plastic product manufacturer’s name, production batch, product composition, certificate test information, etc.
“Our province’s research on the detection of biodegradable materials has just started and there is a need to increase research on the biodegradability of biodegradable materials. At the same time, further enhance the detection capabilities of biodegradable materials,” said Zhao Hongliang, with regarding the detection of biodegradability of biodegradable materials. Regarding the evaluation system, it is urgent to establish a complete evaluation system that covers all types of biodegradable materials. Therefore, the Provincial Institute of Quality Inspection will continue to strengthen and improve the comprehensive capacity building of biodegradable plastic product inspection technology, standards and evaluation systems.
