New technologies for the production of bio-based material polylactic acid can completely solve the "white pollution" problem

[China Packaging Network News] A bio-based biodegradable new material with completely independent intellectual property rights for the production of new polylactic acid, will be produced in Henan Licheng Jindan Lactic Acid Technology Co., Ltd.. The advent of this disruptive technology perfectly solved the construction of an industrial chain for the production of lactic acid from corn, the synthesis of polylactic acid from lactic acid, and the production of fully biodegradable products from polylactic acid, which can completely solve the problem of “white pollution” that plagues countries around the world. It will play an important role in promoting environmental protection and social development. At the same time, it can stimulate the rapid development of industries such as agriculture, industry, food, medicine, and new materials, and it may trigger the rise of a series of independent industries.

For many years, plastics, fibers, and medical materials used by people are petroleum derivatives, which are non-degradable and consume a huge amount. At present, China consumes 60,000 tons of tons per year, which is only used for bags and plastic bags. About 7 million tons. The mass market of plastics brings great convenience to people, but its non-degradability also brings serious environmental pollution. At present, the secondary pollution caused by plastic garbage, plastic incineration and soil damage caused by agricultural film have become global problems. At the same time, the non-renewability of oil also makes it imperative to look for alternatives to petroleum-based plastics.

Technical research and development team Academician of the Chinese Academy of Engineering, Zhang Quanxing, professor of the School of Environment of Nanjing University, and professor Li Hong of the Nanjing University professor and doctoral supervisor think: Bio-based material polylactic acid has non-toxic, non-irritating, high heat resistance, plasticity and good machinability Characteristics are the most promising new materials to replace petroleum-based plastics. Henan Jindan Lactate Science and Technology Co., Ltd., located in Luancheng, has established a strategic cooperation alliance with “Nanjing University, Nanjing University of Technology” to combine “production, learning, research, and application”. The “Biomass Organic Gallium-catalyzed Green Technology to Synthesize Lactide, Polylactic Acid and New Technology” developed by the National Center for Organic Toxicological Substances Pollution Control and Recycling Engineering Technology at Nanjing University solves the problem of the current production of polylactic acid materials compared with traditional plastic materials. High cost, poor processability and other shortcomings; the use of environmentally friendly organic antimony catalyst, completely solved the current production of poly lactic acid using stannous catalyst (stannous octoate, stannous chloride) caused by secondary pollution problems, is The world's first to fill the gaps in the world, with the international leading level, known as a green revolution in the field of new materials, has received great attention and competing pursuits in the international industry.
