Waste Co-processing

Waste co-processing means that waste is used as an alternative fuel or raw material for certain applications, and at the same time, destroying waste. Waste co-processing is usually carried out at high temperatures (over 1000 degrees Celsius) in boilers or kilns in cement plants, power plants, steel plants, etc. AIShred offers pre-preocessing machines for waste co-processing like shredders, screens and other machines. We also provide support for technical retrofits

Waste Tire as an Alternative Fuel of Cement Production Process

Conventional fuels like hard coal and lignite that are commonly used fuels in cement production have high specific CO2 emission values (Hard coal: ~95 kg CO2/GJ; Lignite: ~98 kg CO2/GJ). Consequently, substituting these with other fuels having lower specific emssion values (e.g. fuel oil or natural gas) or with other sources that can satisfy the thermal demand of the processes is an effective way of reducing CO2 emissons. Principally, in cement kilns conventional fossil fuels can be substituted…

Co-processing Waste in Cement Industry

The problem of waste is one of the most urgent on the world agenda, According to the World Bank, the world generates 2.01 billion tonnes of waste every year, with at least 33 percent of that—extremely conservatively—not managed in an environmentally safe manner.Therefore, the most important task is to clear the waste and create a system that will allow separating waste, competently managing its flows, processing it and without harm to nature. Turning the so-called “tailings” into cement, which…

Alternative Fuel Technologies for the Cement Industry

Due to the continuing energy cost fluctuations and the discussions on the sustainable protection of resources the cement industry has hardly enabled to reduce its entire energy and power demand as a result of technical optimisation of its cement production.With the rising energy prices, people have successively used petroleum and coal as the main fuel for cement production. Later, people began to explore the use of waste oil and tires. Nowadays, as people pay more and more attention to reducing…

Industrial Shredder for Cement Industry

Cement production is an extremely energy-intensive process that emits approx. 8% of the world’s CO2. There are huge economic and environmental benefits to be made by replacing fossil fuels with alternative fuels made from waste.Cement producers utilizing alternative fuels such as refuse-derived fuel (RDF) and solid recovered fuel (SRF) can gain a substantial competitive edge. In many cases, however, input waste streams contain diverse materials not suitable for co-processing in the cement kiln…

Shredder for Pre-processing and Co-processing MSW in the Cement Industry

Many processes of co-processing municipal solid waste in cement kilns mostly adopt the method of shredding the waste and then incinerating it in the kiln. Since the municipal solid waste is mixed waste, in order not to affect the cement clinker calcination process and product quality, improve the acceptance ability and control ability of the cement kiln system, shredder machine must be set up. So what kind of shredder is used for pre-processing and co-processing MSW in the cement industry?…
