The project for capturing and utilizing CO2 to produce biodegradable materials by Hebei Zhongmei Xuyang Energy has commenced. Author/Source: Coal-based New Materials. Date: September 7, 2021. Page views: 24. Recently, the new project aimed at capturing and utilizing carbon dioxide to produce biodegradable materials by Hebei Zhongmei has gotten underway! On the morning of August 27, six projects, including Hebei Zhongmei Xuyang Energy Co., Ltd.’s project for capturing and utilizing carbon dioxide to produce biodegradable materials, were launched simultaneously. The total investment in these projects amounts to 1.406 billion yuan, and they cover areas such as industry and urban renewal. The investment in this project is approximately 150 million yuan, and the construction includes a carbon dioxide capture facility with an annual capacity of 7,500 tons, as well as a facility for producing biodegradable materials (PPC) with an annual capacity of 30,000 tons. Yahua Consulting has learned that this project captures carbon dioxide from coke oven flue gas, using a combined amine chemical absorption method and biological charcoal physical adsorption method to achieve an annual capture volume of 7,500 tons of carbon dioxide (over 98%); the captured carbon dioxide is then used to produce the biodegradable material PPC. Hebei Zhongmei Xuyang Energy Co., Ltd. (formerly Hebei Zhongmei Xuyang Coking Co., Ltd.) was established in November 2003. Covering an area of 1,645 mu, it has now reached a production capacity of 4.52 million tons of coke per year, 200,000 tons of coal tar, 50,000 tons of crude benzene, 40,000 tons of sulfuric acid an, 100,000 tons of synthetic ammonia, 1.2 billion cubic meters of gas for external supply. It also has a power generation capacity of 71 MW based on waste heat and waste gas, as well as the ability to produce 100 million cubic meters of natural gas and 220 million cubic meters of hydrogen. PPC, or polypropylene carbonate, also known as polycarbonate propylene, abbreviated as PPC, is an aliphatic polyester primarily synthesized from carbon dioxide and propylene oxide. Based on molecular weight, they can be divided into PPC resins and PPC polyols, with the molecular weight of PPC polyols generally ranging from 2200 to 2800. Using CO2 as a raw material to produce biodegradable plastics and elastomers offers the advantages of both \"CO2 utilization\" and \"biodegradability.\" Against the backdrop of efforts to achieve carbon peak and carbon neutrality, as well as addressing issues such as \"white pollution\" and \"plastic pollution in the oceans,\" this approach is becoming an increasingly attractive direction for development. At present, the market for carbon dioxide-based biodegradable plastics in China has taken initial shape. It mainly includes carbon dioxide/propane oxide copolymers, carbon dioxide/propane oxide/epichlorohydrin terpolymers, and carbon dioxide/propane oxide/ethylene oxide terpolymers. Among these, polypropylene carbonate (hereinafter referred to as PPC) is the most industrially valuable carbon dioxide-based plastic, thanks to its mature production technology and wide range of application areas.
