What are the dangers of non-biodegradable plastics?
Non-biodegradable plastic bags buried in the ground, which take about 200 years to decay, can have an adverse effect on the pH of the soil, degrading the soil environment and thus the quality of the crops.
Non-biodegradable plastic bags are mainly made of polyethylene and polyvinyl chloride, and when people are exposed to vinyl chloride they will have symptoms such as swollen wrists and fingers, sclerosis of the skin, and in severe cases, spleen enlargement and liver damage.
Toxins produced by non-biodegradable plastic bags when heated above 60° are very harmful to humans.
Plastic bags discarded on the ground and water, easily swallowed by animals as food, plastic bags in the gut of animals can not digest, easy to cause animal muscle damage and death.
Do the materials you produce comply with the provisions of the "Opinions on Further Strengthening Plastic Pollution Control" issued by the National Development and Reform Commission and the Ministry of Ecology and Environment in January 2020?
Do the materials you purchase violate the requirements of the "Notice on Solidly Promoting Plastic Pollution Control" jointly issued by nine departments in July 2020?
Can your discarded unused materials comply with the Guangdong Provincial Development and Reform Commission and Guangdong Provincial Department of Ecology and Environment issued in September 2020 "on further strengthening the implementation of plastic pollution control" the spirit of the notice?
The materials involved in your production activities in the Guangdong Provincial Development and Reform Commission, the Guangdong Provincial Department of Ecology and Environment in September 2020 on the issuance of the "Guangdong Province, the prohibition of production, sales and use of plastic products directory"?
Walter Inspection Group Hongcai testing company will check your plastic bags, film bags, express packaging, disposable catering utensils, biodegradable resin, all kinds of plastic products, all kinds of plastic appliances and so on!
Standardized composting conditions
Biodegradable test equipment
Although the Chinese national standard GB/T 19277.1, the International Organization for Standardization standard ISO 14855.1, and the American Society for Testing and Materials standard ASTM D5388 are all about aerobic biodegradation under controlled composting conditions, none of them describe what kind of equipment can be used to achieve such composting conditions, in other words, none of them depict In other words, there is no standard that depicts what a standardized composting condition biodegradable test equipment would look like.
With the concept of standardization, we have developed a standardized composting condition biodegradable test equipment 3C36G58, which is the most standardized composting condition biodegradable test equipment in the world.
As soon as the "standardized compost biodegradable test equipment" 3C36G58 was developed by Hongcai Testing of Wote Group, five institutions, including famous microbial research institutions, microbial academic authority colleges and universities, and peers who have been immersed in the microbial field for many years, were invited to conduct inter-laboratory comparison of valuable samples, and the results were very satisfactory. The results were very satisfactory; Walter Group Hongcai testing and non-stop GB/T 19277.1, ISO14855.1 and ASTM D5388 method validation, and immediately after the verification to apply for CMA accreditation, thanks to the deep accumulation of the previous, Walter Group Hongcai testing one-time through the audit to obtain CMA accreditation; so far, Walter Group Hongcai testing has been for more than twenty To date, Hongcai Testing has provided standardized composting biodegradability testing services to more than twenty manufacturers and users of plastic bags, film bags, courier packaging, disposable food and beverage utensils, biodegradable resins, various plastic products and various plastic appliances, and has been widely recognized in the industry. The recognition of our customers is the direction that Walter Group Hongcai Testing strives for!
Biodegradable testing process
The material under test and the compost inoculum are mixed and introduced into the composting vessel. Under oxygenated composting conditions, the organic compounds of the material under test are decomposed by microorganisms into carbon dioxide (CO2), water (H2O) and mineralized inorganic salts and newborn substances of the elements they contain, and then carbon dioxide (CO2) is collected by traditional classical chemical means, and the amount of carbon dioxide (CO2) is measured by an advanced TOC meter to determine the final biodegradability of the material under test.
