a Chinese company conducted an experiment of SRF alternative fuel used in industrial kilns, exploring "How much coal can be saved by the use of alternative fuel?" in the process data and practical results.

Har Der alternative fuel preparation technology can easily solve more than 100,000 tons of paper waste.

Solid waste is used, and the final discharge is SRF alternative fuel.

So what should be done?
Solid waste composition complex, low calorific value problems?

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.

The management and disposal of solid waste are one of the major challenges facing the world. How to protect public health and the environment through effective treatment methods, technologies and concepts is the top priority.

Solid waste shredder is widely used in all kinds of solid waste applications, and with the actual demand for different situation, single shaft shredder, double shaft shredder, four shaft shredder, primary shredder, and mobile shredder have been continuously developed.

Biomass raw materials are rich and diverse enough. Because it is pollution-free to the environment, it is supported by national policies and technologies. Therefore, it can be seen that biomass energy has broad development prospects in the future energy field.

RDF is a solid waste-derived fuel that is reprocessed from raw waste through complex processes such as primary shredding, sorting, magnetic separation, secondary shredding, drying, and granulation.

It’s important for us to distinguish between solid waste and industrial solid waste because of the different treatment methods. Today, we will show you the difference and the most recycling method for your own waste.

Recently, Harden was invited to attend the Two networks integration of recyclable System Construction Conference sponsored by China Renewable Resources Recycling and Utilization Association and undertaken by the Two networks integration Professional Committee of China Renewable Resources Recycling and Utilization Association.

Combined with the centralized bulky waste processing system provided by HARDEN, the bulky waste disposal enterprise achieves 100% resource utilization rate of bulky waste through fine disposal processes such as automatic shredding, pulse dust removal, automatic air separation, automatic magnetic separation, and RDF granulation, finally reuses bulky waste.

The double shaft shredder is especially used for wood, waste plastic, waste rubber tires, bulky waste, municipal solid waste, medical waste shredding.

The recycling system for waste rubber tires ensures small size discharge and promises high throughput of TDF.

75% of the hydraulic system failures are caused by these three problems: pollution, overheating and air intake. So how to keep the hydraulic system away from these three problems, the secret is scientific and effective maintenance operations.
