Established in Oct. 29, 2015, Jilin Province Kangrunjie Environmental Protection Technology Co., Ltd lies in No. 9, Liangchen Industrial Park, Xinglongshan Town, Economic and Technological Development Zone, Changchun, Jilin Province, China, with the registered capital of 10,000,000 Yuan.It is the wholly-owned subsidiary of Xinjiang Kangrunjie Environment Protection Science-Tech. Co., Ltd. (hereinafter called Kangrunjie or the company), which was established and registered in Nov., 2008. The company is a scientific and technological enterprise engages in research, development, manufacture and sales of high polymer materials, mainly in biodegradable polyester, and the downstream environment-friendly productions. Identified as the national high-tech enterprise, and awarded as one of the "First Batch of Chinese Agricultural Ecological Protection Association&＃39;s Agricultural Plastic Film Pollution Control Branch Members" and "Urumqi Innovative Enterprises", the company was listed on NEEQ (National Equities Exchange and Quotations) in Sept., 2015.The company has built up the patent portfolio with the core of biodegradable polyester material. By 10 years&＃39; efforts, the company has found the formula for making polyester with the main material of polyester (PBAT) and polylactic acid (PLA), by which the company is building the technology strategic layout of "One Generation under Research and Development, Another Generation under Exploitation, the Other Generation under Reserve, and All Patents under Protection". There are 8 patents for invention (3 patents are authorized, 5 patents are accepted), 2 patents for utility models (1 patent is authorized, 1 patent is accepted), and ongoing relevant applied research encompassing many areas like agriculture, medical treatment and public health, daily life, engineering, packaging, military application, etc. The company has finished the full set of technology research in replacement for the petrochemical material by the industrial waste, dramatically reduced the cost of manufacture. Corresponding achievements&＃39; popularization and application will bring about the deep change of environment protection from "Plastic Replacement" to "Petrochemical Disuse", which are very promising.
