BBCA currently reserves the technology to use straws to produce polylactic acid. About 4 tons of straws produce 1 ton of polylactic acid and 1 ton of wood plastic materials. Wood plastic materials produced by using polylactic acid as a binder do not contain bisphenol A and formaldehyde (urea-formaldehyde resins, phenolic resins), and are widely used in indoor and outdoor decoration, furniture manufacturing, office furniture, etc.

   BBCA also reserves the technology to use straw cellulose to produce PLA. As early as 2010, BBCA Group built an industrial demonstration project that used corn straw as raw materials to produce 5000 tons/year of fuel ethanol and 1000 tons/year of lactic acid, and passed the acceptance of the Department of Science and Technology of Anhui Province.

   After the PLA industry has developed to a large scale, in response to market competition and raw material supply pressure, BBCA Biochemical plans to use crop straws as raw materials to produce PLA series products after 2025, to ensure the sustainable and rapid development of the new bio-based material PLA industry.
