Subject objective

+ Creating basis for receiving, deploying, researching the technology of manufacturing Polylactic acid as material for manufacturing types of materials such as blend materials, biological self-decaying composite materials and other products friendly to the environment.

+ On science: Building the scientific cadre team having scientific and technological knowledge about biological polymer materials, having ability to receive, deploy, research, and manufacture new materials, materials friendly to the environment.

+ On technology: Building the technology of treating agricultural and forestry waste to become material for green chemistry technology including:

• Enzyme technology for hydrolyzing agricultural waste (straw, thatch, bamboo, neohouzeaua) to form dissolved intermediate product with high efficiency.
• Technology of fermenting general acid-L-lactic microorganism
• Technology of polymerizing acid L-(+)-lactic to become Polylactic acid.
• Technology of manufacturing types of blend materials, biological self-decaying composite materials and other products friendly to the environment.
