Under the environment of global carbon emission reduction, cement production with low carbon emission is an important direction of cement industry development.

According to different material properties and shredding requirements, different types of shredders will be selected, such as single shaft shredder, double shaft shredder, primary shredder, and four shaft shredder. Each shredder has its own suitable application field. As a representative of high production capacity and small discharge size, single shaft shredder is well recognized by customers.

With the continuous development of the comprehensive strength of various countries, various industries have been better promoted, among which industry promotes social progress and has a bearing on the national economy. The industrial industry itself has specific particularity, the production process to form a large number of economic benefits, but also brings great damage to the environment.

In the whole cement production process, the clinker production stage has the largest carbon dioxide emission, accounting for about 95% of the total production process, most of which comes from the calcination of limestone, a small amount from the fuel used in the process.

Encouraging the application of alternative energy sources such as hydrogen, biofuels and waste-derived fuels in the steel, cement, chemical and other industries will help reduce carbon dioxide emissions. The preparation of solid recovered fuel (SRF)/refused-derived fuel (RDF) from general industrial solid waste is an important step in the process of alternative fuel.

We can often see all kinds of bulky waste such as sofas, mattresses, and furniture being discarded next to the garbage station in our daily life. It will cause difficulties for residents and fire hazards. There is no doubt that a reliable bulky waste recycling system plays an important role in solid waste management for urban area.

MSW is collected, transported and processed by the sanitation department in various residential areas or public places, and then sent to the landfill site and waste incineration plant according to different needs. This treatment method is simple and easy to operate, and has low requirements for facilities and management, which is widely adopted by most cities.

Recycled paper waste can be divided into two categories: coarse material and fine material. Coarse materials mainly come from pulping and slag removal stages, most of which are rope; The fine material mainly comes from the cleaning and screening stage, and the fine material can be divided into light slag and heavy slag. These paper waste residues contain plastics, metals, and other mixtures, which are very difficult to produce in a renewable manner.

Waste mattresses, sofas, furniture and other bulky waste can be seen everywhere, which significantly affects residents’ travel and the beauty of the city. So how to handle this kind of bulky waste is a challenge for all of us.

Receive the delivery, take out the goods, and then casually throw the packing case into the garbage... But few people are concerned about where the waste ends up and how it is disposed of.

China has carried out comprehensive garbage classification since 2019. By the end of 2021, the harmless treatment capacity of national MSW (municipal solid waste) has reached 994,900 tons/day, and the harmless treatment rate is 99.7%. Among them, refined treatment such as size reduction, harmless treatment and resource recovery has become an important direction for the future development of the municipal solid waste industry.

Waste-Free city adopts new development concepts of innovation, harmony, environmentally friendly and sharing, by promoting green development mode and lifestyle, continuously promoting solid waste reduction and minimizing landfill places. It is regarded as an advanced concept of urban management.

According to statistics, China's raw coal output reached 4.13 billion tons, and coal consumption accounted for 56% of the total energy consumption in 2021. There is no doubt that China's energy security has always been inseparable from coal. However, coal prices have continued to rise in recent years, with prices in September 2021 already 1.9 times higher than the same period in 2020.

Most of the landfill waste comes from the solid waste generated in the daily life of the city or the activities providing services for the daily life of the city. However, the number and scale of existing landfills are far from enough to meet the growing demand for urban waste, especially at a time when every city is trying to build a "green" livable city. Therefore, recycling landfill waste is an inevitable trend.
