Classification of chemical industry, what are

The chemical industry is the general term for enterprises and units engaged in the production and development of the chemical industry. The chemical industry penetrates all aspects and is an indispensable and important part of the national economy. Its development is to take the road of sustainable development and has important practical significance for human economic and social development.

Overview

The chemical industry occupies an important position in the national economy of various countries, and is the basic industry and pillar industry of many countries. The development speed and scale of the chemical industry have a direct impact on all sectors of the social economy. The annual output value of chemical products in the world has exceeded US$1.5 trillion. The chemical industry is a major polluter due to its diverse categories, complex processes, and diverse products, as well as many types, large quantities, and high toxicity of pollutants emitted during production. At the same time, chemical products may produce large amounts of toxic substances in various links such as processing, storage, use and waste disposal, which affect the ecological environment and endanger human health. The sustainable development of the chemical industry has important practical significance for human economic and social development.
