How about Lang Jing Huiming Biotechnology Co., Ltd.

After eight years of painstaking research and development, the PLA technical team of Beijing Lang Jing Huiming Biotechnology Co., Ltd. has overcome the technical barrier of PLA localization, and formed a set of industrialized "two-step method" to produce PLA with high optical purity, which has the international advanced level and the production cost can be further reduced by more than 20%. This industrial chain linking trillions of markets has settled in Zibo, and Zibo has thus become one of the production bases of new degradable materials in China. After overcoming the most difficult core technology of lactide, Lang Jing Huiming became one of the few leading enterprises in the industry to master the industrial chain of lactic acid, lactide and polylactic acid as well as the research and development and industrialization of stereoscopic lactic acid technology. This is a good company.
