The Importance of Alternative Fuel Preparation for the Cement Industry

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.

Moreover, due to the increase in coal prices in recent years, the price has increased by two to three times compared to the same period. Since this is the main fuel used in cement production, it increases the production cost of enterprises to some extent.

Therefore, one of the most important things in carbon dioxide emission in the cement industry is to reduce fossil fuel or even not use fossil fuel.  

The solid recovered fuel (SRF)/refuse-derived fuel (RDF) preparation system developed by Harden is based on the fuel perspective in the cement industry, which extracts the high calorific value of combustible solid waste from the waste, and then processes it to produce green energy. Not only the waste reduction, harmless, resource, but also reduce the clinker production of fossil energy consumption, so as to achieve carbon reduction and economic win-win.

As one of the drafting units of the alternative fuel standard, Harden has been deeply engaged in the solid waste treatment industry for more than ten years. We have rich practical experience in the comprehensive reuse and treatment of harmless, reductive and resource-based in municipal solid waste (MSW), general industrial solid waste, bulky waste, paper mill waste, legacy waste, biomass straw, waste rubber tires and other aspects.

Through shredding, sorting, screening and granulation, Harden provides each industry the reliable solid recovered fuel (SRF) Preparation system and equipment, turning high calorific value solid waste into SRF/Refuse-derived fuel (RDF).

Under the situation of carbon emission reduction, the implementation of green and low-carbon circular economy recycles the combustible solid waste generated in daily life and produces it into RDF/SRF, which can be used to replace coal, oil, natural gas and other fossil fuels. It is an innovative development road of energy conservation, emission reduction, green and low-carbon development in the future of the world.
