However, compared with developed countries, the sewage treatment activated carbon industry in Lianyungang, China still has a huge gap, mainly manifested in: small-scale enterprises, outdated production equipment, low labor productivity, and weak market competitiveness. 90% of the wood-based activated carbon factories in China are small enterprises that produce hundreds to thousands of tons per year, and there are almost no factories with annual production capacity of more than 10,000 tons. Most of them are township enterprises, distributed in forested areas, with small scale, outdated production equipment that is difficult to update, and similar main equipment. Labor productivity is generally in the range of tens of tons per person per year or lower. However, in foreign countries, activated carbon production is concentrated in large enterprises with annual production capacity of more than 10,000 tons, such as the United States and Japan. These large enterprises not only have large output, advanced production equipment, but also have fully automated production lines and computer management and control, so labor productivity is very high, reaching hundreds of tons per person per year.

China is a country with few forests, and activated carbon can only be produced using forestry processing by-products as raw materials. Individual enterprise owners seek to maximize profits and ignore forest protection and ecological environment, clear-cutting forests to burn charcoal, causing forest destruction and soil and water loss. In recent years, although some manufacturers have made efforts to combat environmental pollution, they have not yet been fundamentally solved due to reasons such as funds, technology, and equipment.
