The circular economy industry chain in chemical industrial parks

The Nanjing Chemical Industrial Park seems to be like that

　　Typical representatives of chemical industrial parks in our country include the Shanghai Chemical Industrial Park, the Nanjing Chemical Industrial Park, and the Huizhou Industrial Park. These parks are led by oil refining and ethylene production facilities on a world-class scale; they are connected to each other through product chains, and integrated utility systems are established to ensure centralized supply of water, electricity, heat, and gas. They operate under an open management model. Such an integrated development model facilitates the optimal allocation of resources, enables the extended processing of products across upstream, midstream, and downstream stages, and fosters closely linked industrial clusters. The cyclic organic chains drive the energy-consuming industry toward a transformation aimed at resource efficiency and environmental sustainability.

The planning project for the Yinglitening East Industrial Park is based on coal-based combined production. It takes the three major product chains of acetylene-related products, methanol-related products, and chlorine-related products as its core, features acetylene chemistry, and follows a process route that integrates C1 chemistry with C2 chemistry. By making full use of its resource advantages and adhering to the three R principles of circular economy—reduction, resource utilization, and reuse—as well as sustainable development, the park will be developed into a model industrial park characterized by large-scale equipment, combined production facilities, and integrated industries.

The industrial planning of Hainan Dongfang Industrial Zone in Dongfang City, Hainan Province is reasonably structured

The Shenyang Chemical Industrial Park is under construction and it looks pretty good!

In Tangshan, there is Sanyou Chemical, which does well in this area. Starting with caustic soda, it moves on to producing fibers and methanol, etc., by using the waste from one production process as raw material for another

There needs to be a leading enterprise, with supporting companies to form a complete industrial chain; the availability of hydroelectric, thermal, and gas power is essential.

The Shanghai Chemical Industrial Park is also nice

A biomass thermal power plant can be established in industrial parks at the county level. Comprehensive utilization of biomass – electricity – heat – ash. It can be considered a form of circular economy as well. For enterprises with high steam consumption, it is advisable to have their own biomass thermal power plant. It not only aligns with **green energy policies but also saves a significant amount of money on electricity and heating costs. It can also employ the surplus labor force in rural areas and increase farmers’ incomes. Personally, I think it’s a pretty good format.
