I am afraid that the most popular word nowadays is the number of circular economy.
In theory, the circular economy is based on the principle of efficient use and recycling of resources, with the principle of reduction, reuse, and recycling. It is characterized by low consumption, low emissions, and high efficiency, and is consistent with sustainability. The economic growth model of the development concept is a fundamental change to the traditional growth model of 'mass production, mass consumption, and mass disposal'. The circular economy is also called closed-loop resource-based economy. While maintaining the expansion of production and economic growth, a clean and closed-loop flow model of 'resources-production-products-consumption-recycling' is established, and resources composed of ecological industrial chains are established. Recycling type. Taking the large-scale eco-industrial chain of 'Sulfuric Acid Plant-Phosphate Fertilizer Plant-Cement Plant' that has been successfully developed in China as an example, the sulfuric acid plant's sulfuric acid is used as a phosphate fertilizer plant for the production of phosphate fertilizers. The by-product gypsum is decomposed by heat into sulfur dioxide and quicklime. Cement is produced at a cement plant, and sulfur dioxide is sent to a sulfuric acid plant to produce sulfuric acid. This will not only solve the pollution problem of large amounts of gypsum, but also make the sulfur element recycled. This model truly achieves material recycling.
However, some chemical companies regard the circular economy as a kind of economy. The upstream and downstream products together seem to be circulating this way. The result is that the cycle is cyclical, but it is not economical. A coking enterprise that had been very successful in a county in Shanxi Province, made coal mines upwards and made steel downwards, thinking that it was a major cycle, and the result was indigestion and a lack of energy. The lesson of this enterprise is that if a company closes its doors and engages in a circular economy, from the surface it seems that the company 'takes all' of the entire industry chain and the resources are exhausted. It seems that the external transaction costs have been reduced, but maybe Because there is no sufficient market competition, the internal transaction costs will be higher than the outside. From the theory of market economy division of labor, the development of enterprises should also engage in division of labor and collaboration. The principle of division of labor is that each company concentrates on producing products with advantages and then uses its own products to exchange the products it needs. This can greatly increase labor productivity and increase their respective benefits.
Therefore, engaging in circular economy should be based on local conditions.
