On July 31st, under the guidance of Yang Yexin, President of China National Petroleum Corporation (CNPC), the groundbreaking ceremony for the CNPC COâ‚‚ degradable plastics (PPC) project took place at the construction site. This milestone marks a significant step forward in the development of sustainable and eco-friendly materials.
The project, which began in 2004, focused on technology development, equipment research, market analysis, and product innovation. It utilizes world-leading patented technology developed independently by the Changchun Institute of Applied Chemistry, part of the Chinese Academy of Sciences. The facility is designed to have an annual production capacity of 3,000 tons—making it the largest of its kind globally, as the previous record was 1,000 tons. With a total investment of approximately RMB 152.2 million, the project is expected to be completed and start operations by June 2008. It is a joint effort between CNOOC and the Changchun Institute of Applied Chemistry, located within the Dongfang Chemical City, a CNOOC subsidiary. China Oil One Construction Co., Ltd. is responsible for the project's construction and ongoing operational management.
The primary raw materials used in the process are carbon dioxide from industrial exhaust gas and propylene oxide. Under the influence of a catalyst, these two substances undergo copolymerization to produce COâ‚‚-degradable plastic. This innovative material is fully biodegradable, environmentally friendly, and has excellent transparency, degradability, high barrier properties, and biocompatibility. It can be modified for use in injection molding, extrusion, and blow molding, making it suitable for applications in medical, food, and agricultural industries. It has the potential to replace many non-degradable plastic products.
In recent years, CNOOC, in collaboration with Jilin Jinyuan North Science and Technology Development Co., Ltd. and Sun Yat-sen University, has made significant progress in developing medical materials, pharmaceutical packaging, flexible films, foaming materials, and disposable tableware. They have successfully produced medical dressings, capsules, blister packs, and other essential products. These developments demonstrate the practicality and commercial viability of COâ‚‚-based plastics.
By utilizing COâ‚‚ emissions as a raw material, this project not only helps reduce "white pollution" but also decreases the reliance on oil and gas resources in plastic manufacturing. It represents a promising step toward a greener future in the plastics industry.
