Project

The integrated alternative fuel preparation system of industrial waste and bulky waste provided by Harden has been put into operation, which is designed to deal with 100,000 tons of industrial waste and 40,000 tons of bulky waste annually. It adopts solid recovered fuel (SRF) and refuse-derived fuel (RDF) preparation technology to effectively recycle and process industrial waste and the bulky waste generated from local light industrial areas, and prepare SRF or RDF to reduce carbon emissions

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.

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.

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.

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.

Under the guidance of Construction Work Plan for Waste-free City in Zhejiang Province, Harden is committed to assisting environmental protection enterprises to realize the resource disposal of industrial waste, and to create a comprehensive industrial chain of industrial solid waste recovery, volume reduction and harmless treatment, so as to minimize the environmental impact.

At 16:50 PM on November 23, 2021, the 8 x 1MW agricultural and forestry biomass cogeneration project from DR (WuChang) Biomass Development Limited produced 41000m³/d gas, which meant that the dry straw for biogas power generation project successfully reached production target in China.

With the help of the technological means of Internet of things, the bulky waste treatment project has established its own recycling system, combined with the new core technology scheme of bulky waste resource disposal, so that the resource utilization rate of bulky waste can reach 100%, and the bulky waste can be truly turned into treasure.

The whole paper mill waste recycling system contains robust double shaft shredder, magnetic separator, eddy current separator, wind shifter to turn the paper mill waste into alternative fuel.

One of the hazardous waste shredding systems based on Harden's shredding technology was running on-site as a solid waste demonstration project.

Harden® provides a one-stop (Lifting Machine + Shredder + Conveyor) medical waste pretreatment solution, greatly improving the efficiency of medical waste crushing.

So far, Harden has been supplying 2 sets of equipments for hazardous waste shredding disposal and have been operating stably for more than 500 days, and the cumulative handling capacity of hazardous waste over 30,000 tons.

Material: Hazardous waste including hazardous solid waste, medical waste, dead animal
Requirement: to meet the treatment capacity of 45,000 tons of industrial waste in HUZHOU and surrounding areas

The project covers an area of about 70,000 ㎡with a construction area reaching 16,000 ㎡, the average daily capacity is about 160 tons.

Capacity: 15 ton/day
Material: domestic waste
Output: ≤30mm
Project Description: Using shredded domestic waste as fuel to support the production line of new dry process cement.

With Harden sequence of bulky waste management system, Quanzhou Beifeng Domestic Waste Transfer Station have been put into operation and operated well for over a year. This is the first bulky waste treatment project in Fujian Province, China.

Organic materials come from living plants and animals, like fruit and vegetables waste, kitchen waste, supermarket waste, expired food waste, etc. Organic waste are best managed as a resource rather than a waste. Organic waste are part of our life, how to manage organic waste and turn them into valuable and clean resource is a high priority of the organic waste management center.

Recently, Harden leather scrap shredding system (two shaft shredder model TDH1216 and TD912) was successfully passed the inspection and now is working for the Wenzhou Hongze Thermal Power Plant. This kind of leather scrap industrial shredder has the largest leather scrap disposal capacity of similar projects in China at present. The production capacity of waste leather scrap is up to 20T / hour.

As the largest city excelling at chemical industry province in China, Shandong province has a hazardous waste disposal center which is located in Circular Economy Demonstration Park in Dezhou City. It is the only comprehensive solid hazardous waste disposal site in Dezhou city. This disposal center can realize the hazardous waste resource recycling, hazardous waste reduction and harmless disposal of hazardous wastes.
