PJCHEM shoulders the responsibility of protecting environment voluntarily, helps the industrialized development of global biodegradable material field, and actively promotes the exploration and popularization of biodegradable technology and materials. The developed novel biodegradable material PGA can realize full degradation under the condition of sea environment, domestic composting and industrial composting. We are making efforts to apply novel technology and material to medical service, engineering plastics, delivery packing materials, barrier packaging materials, fully-biodegradable plastic bags, farming film and disposable products like straws and meal boxes, contributing to the implementation of national policy of banning plastics.
