Cement is a traditional industry with high energy consumption. Fuel and power cost account for more than 50% of cement production costs. Because coal prices have nearly tripled since 2021, the fuel costs for cement plants have also increased, forcing the industry to raise cement prices to maintain profits.

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.

As one of the most critical industries in the world, paper mills supply a variety of products to five billion people, while also producing a large amount of waste. Statistics show that an annual output of 1.5 million tons of recycled paper production factory has more than 180,000 tons of paper mill waste per year. How should paper mills deal with this paper mill waste in the face of such a large number of paper mill waste?

Recently, one of the industrial waste recycling treatment system built by Harden has been put into operation.

With the rapid development of the industrial economy, a large amount of industrial solid waste has hindered the sustainable development of urban and rural construction. How to treat this industrial solid waste harmlessly has become the urgent demand of most waste producing enterprises.

In the past, the general industrial solid waste was mainly processed by incineration, landfill and other treatment methods. Still, these two methods not only cause material waste, and do not conform to the national environmental protection policy and the concept of the circular economy.

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.

Harden will be participating in the 2022 India International Environmental Expo at the Mumbai Exhibition Centre from Sept 28 to 30.

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.

Re-Tech, an annual environmental fair in Seoul, South Korea, was held by GENTA, the organizing committee of the International Resource Recycling Industry, from August 31 to September 2.

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.

In the past three years, all cities in China have been actively building Waste-Free City. The waste-free city project has been promoted from the 13th Five-Year Plan to the 14th Five-Year Plan, and from 11+5 pilot cities to more than 100 cities at present. Obviously, the construction of a waste-free city has developed in the right direction.

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.

IFAT India – India’s leading environmental technology trade fair provides an ideal platform to network with key industry players, innovators and business partners from across the globe. Addressing sewage systems, adequate waste-water treatment, sustainable ways for water supply, holistic solid waste management and recycling, amongst others, - IFAT India showcases solutions to resolve the environmental concerns of the hour.

ASEAN Sustainable Energy Week 2022 (ASEW) is the most comprehensive energy event in the region. The event has over three decades of service in presenting unbeatable regional business platforms and meeting points for manufacturers to showcase their cutting-edge energy technology for trade visitors, entrepreneurs and policy-makers and professionals in the energy industry in the region.

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.

The system is mainly aimed at the shredding treatment and incineration of tons of drums, 200L iron drums or plastic drums (empty drums or containing semi-solid, solid material sludge block, resin, paint residue, drugs, packaging bags, woven bags, waste cloth, and other bulk hazardous waste)，and other materials.

With the development of urbanization, the production of bulky waste and garden waste increases sharply, and its resource treatment has become an important theme of urban waste management. The disposal of traditional bulky waste and landscaping garbage is mainly simple landfill, and even random stacking, which not only wastes land, affects the urban environment, but also may cause fire accidents, and is also a serious waste of resources.

As one of the key objects of the Ministry of Environmental Protection, how to reduce, recycle and harmless treatment of paper mill waste (light reject and pulper rope) generated in the production process has become the main challenge of every papermaking enterprise.

Under the guidance of Zhejiang Province Waste-Free City Construction Work Plan, Harden assists Zhejiang environmental protection enterprises to achieve the resource treatment of general industrial waste, creating a comprehensive industrial chain of industrial solid waste resource utilization, waste reduction, and harmless treatment, helping Zhejiang to achieve a new model of green development.

The country mentioned in the 14th Five-Year Plan to increase the proportion of clean energy consumption. The application of alternative energy such as hydrogen energy, biofuel, and waste-derived fuel in the steel, cement, and chemical industries will be encouraged. Recently, a regulation pointed out that alternative fuel technology should be promoted to replace coal with domestic waste, solid waste, and biomass fuel, reducing fossil fuel consumption.
