On July 14, 2020, the website of the Ministry of Industry and Information Technology published an article "China's polyglycolic acid (PGA) biodegradable plastics industry has accelerated the pace"
With the strengthening of global environmental protection, "plastic restriction" has been implemented in many countries
In recent years, developed countries such as Japan and the United States have actively developed new petroleum-based degradable plastics such as polyglycolic acid (PGA) and aliphatic polyester (PCL)
In recent years, China's PGA technology research and development has made positive progress
The above is the full text of the article "China's Polyglycolic Acid (PGA) Biodegradable Plastics Industry Accelerates" on the website of the Ministry of Industry and Information Technology
Glycolic acid is the main synthetic raw material for the biodegradable polyglycolic acid (PGA).
The traditional glycolic acid production process is the hydroxyacetonitrile acid hydrolysis method, which has high toxicity and high cost, and other processes cannot be produced on a large scale due to their insurmountable shortcomings
By replacing the hydrogenation catalyst of DMO, it is possible to switch from the production of ethylene glycol to the production of methyl glycolate (MG) or glycolic acid (GA), and then to produce PGA
