Alternative Fuel

As industries worldwide seek sustainable alternatives to traditional fuel sources, cement plants are turning to innovative solutions such as alternative fuels. Shredders play a crucial role in this transition, enabling the efficient processing of diverse waste materials into valuable fuel sources. This article explores the integration of shredders in cement plants for alternative fuel production, highlighting the benefits and advancements in sustainable energy practices.The Need for Alternative FuelsCement production is energy-intensive, relying heavily on fossil fuels such as coal and petroleum coke. However, the environmental impact of fossil fuel combustion, including greenhouse gas emissions and air pollution, necessitates the adoption of alternative fuels. Alternative fuels derived from waste materials offer a sustainable solution, reducing reliance on finite resources and mitigating environmental impact.Role of Shredders Shredders are indispensable equipment in the production of alternative fuels for

In the pulp and paper production process, it will produce a variety of solid waste (i.e., slag), for example, an annual production capacity of 1 million tons of paper mills, the amount of slag accounted for about 10% of the amount of slag, i.e., 100,000 tons / year, which is a huge number, and highly concentrated, such as improper disposal, but also cause significant pollution and endanger the ecological environment. The composition of paper waste is very complex, mainly contains: rope, cotton yarn, cotton cloth, paper residue, wood chips, rubber, plastic, electronic parts, wire, nails, aluminum cans, PE plastic bottles, waxed paper and glass, stone and sand. Paper waste residue can be used to make solid alternative fuels, a utilization that not only reduces waste, but also replaces traditional fossil energy sources and reduces carbon emissions.The plastics in paper waste residue cannot be degraded, and direct stacking seriously affects the ecological environment. At present, there are paper waste separation

Solid alternative fuel RDF/SRF is a solid form of fuel made from industrial solid waste through various processes. By reducing the water content of industrial waste and increasing the calorific value of the product, it replaces traditional energy sources (coal) and reduces pollutant emissions, thus realizing "turning waste into treasure".From the perspective of energy structure, alternative fuels (SRF/RDF), as a renewable energy source with broad prospects, are processed from solid wastes, with combustion efficiencies similar to those of fossil fuels, but with low carbon emissions, and are generally utilized in existing thermal power plants, cogeneration plants, and cement kilns to carry out coupled power generation/blending power generation/mixing power generation/co-disposal in cement kilns with RDF/SRF, which saves costs for enterprises and contributes to the environmental protection. The substitution relationship between fossil fuels and alternative fuels (SRF/RDF) is:- 1.4 tons of alternative fuel = 1

It can provide professional solutions and high-performance equipment for the green transformation of cement enterprises.1. Cement kiln collaborative disposal of solid waste technologyCement kiln collaborative disposal of solid waste technology uses solid waste to replace some raw materials or fuels, enabling cement production enterprises to save on raw material demand, reduce energy consumption, and achieve complete resource utilization. At the same time, the carbon dioxide released by the decomposition of calcium carbonate is reduced, saving on the occupation of waste landfills. It meets the requirements of energy conservation, consumption reduction, and emission reduction, and has significant economic and environmental benefits.2. What are the sources of alternative fuels for cement kilns?Alternative fuels refer to fuels that

When it comes to discarded shoes, many people think about how to properly dispose of them, and one potential solution is to convert old shoes into solid recovered fuel (SRF). Although this may sound surprising, in theory, this approach is possible. Here are some considerations for converting old shoes into solid recovered fuel .Why can old shoes be used as solid recovered fuel ?Discarded shoes contain a variety of materials such as rubber, leather, synthetic fibers and metal trimmings. The processing and utilization of these materials, especially the combustion potential of rubber and synthetic fibers, makes discarded shoes a potential solid recovered fuel .Advantages of using old shoes as solid recovered fuelHigh calorific valueSmall particle sizelow moisture contentManufacturing process of using old shoes as solid recovered fuelPrimary shredding (shred to 30 mm),Screening to remove fine materials (helps reduce moisture content), trommel screen recovery or air density separation to remove heavy components,

Recently, many customers have inquired whether it is possible to convert all MSW (Municipal Solid Waste) into high calorific value RDF? Here, it should be explained that in the field of MSW classification, many countries and regions currently do not reach the level of complete segmentation. MSW is still mixed with a large amount of kitchen waste, as well as low calorific value non combustible materials such as porcelain chips and stones. It is impossible to make such materials into high calorific value alternative fuels. Therefore, before MSW can be converted into alternative fuels, a series of shredding and screening equipment must be used to separate the non combustible materials inside, and the remaining combustible materials can be processed into high calorific alternative fuels RDF/SRF.The specific disposal process is as follows: MSW is transported to the MSW disposal center through specialized transportation vehicles, first dumped into the waste storage pit in the disposal center, and then collected

Mixed municipal waste contains a large number of recyclable beverage bottles, metals, cardboard and other renewable resources that can be recycled and reused; the content of perishable waste, mainly food waste, accounts for 40-60%, which can be utilized as a biomass energy source; and the largest proportion is still high-calorific-value combustibles, which can be prepared as "alternative fuels (RDF/SRF)" to reduce the use of coal combustion.AIShred, as a manufacturer of solid waste pre-processing equipment, offers a complete range of proven and reliable systems and equipment for the preparation of alternative fuels (SRF) based on the three main pre-processing objectives of mixed domestic/other waste: "sorting of recyclables", "extraction of organic matter", and "preparation of combustible materials for RDF/SRF".The whole set of domestic garbage alternative fuel (SRF) preparation system adopts the automatic process design of "feeding - bag breaking - screening - recycling - crushing - transportation", which

1. Definition of SRF:SRF is the abbreviation for Solid Recovered Fuel. SRF is usually a refined RDF (Refuse Derived Fuel). SRF is not waste, but a clean, homogeneous, high-quality, and high calorific value fuel that can be used in power plants or cement plants to replace traditional fossil fuels such as coal. Moreover, SRF is a kind of environmentally friendly fuel, with carbon dioxide emissions only one-fourth that of coal, and NOx emissions significantly reduced. 2. Component analysis:SRF is usually composed of papermaking waste, waste wood, biomass fuel, combustible materials in MSW (Municipal Solid Waste), and waste textiles in general industrial solid waste. 3. Process flow:Firstly, the material is transported to a primary double shaft shearing shredder, which shreds the material into smaller sizes of around 100-300mm. Then these materials enter the magnetic separator, through which the ferromagnetic metals inside the materials are recycled. The remaining materials are transported to a secondary single

With the global demand for cement on the rise, the cement industry faces an imperative to adopt sustainable practices that minimize its environmental impact.

GEP ECOTECH's Alternative Fuel System serves as a game-changer in cement

During the production of cement, clinker needs to be calcined at a high temperature of 1300-1450°C, which will consume a large amount of fossil energy, and the carbon dioxide produced by the combustion of fossil fuels accounts for about 30%-35% of the total carbon emissions of cement companies. The application of alternative fuels to reduce the use of coal has received attention in the cement industry and can significantly reduce the carbon emissions from fuel combustion. As a promising renewable energy source, alternative fuels (SRF/RDF) have become the fourth largest energy source after coal, oil and natural gas for various industrial kilns such as cement kilns and fluidized beds. Alternative fuels as a high-quality environmentally friendly renewable resources, itself from solid waste waste treatment, combustion efficiency and fossil fuels similar, but low carbon emissions, to meet the policy requirements of carbon emission reduction, cost savings for enterprises, has an important significance for

In recent years, the popular term "RDF" in the field of solid waste refers to waste derived fuels, and most environmentalists have also turned their attention to the field of household waste. The composition of household waste we usually refer to is a mixture of wet waste and dry waste, while in the preparation of fuel for household waste, it is best to make a distinction based on current incineration needs. Frontend differentiation can reduce the investment cost of pre-treatment production lines while also improving the calorific value of materials. In the field of incineration, calorific value is a sensitive term. In fact, this process flow is not complicated. Our designed process principles have three positioning points: "impurity removal, reusable selection, and combustible compression". These three process points constitute the equipment solutions applicable in the current field of solid waste disposal. The impurity removal we refer to can be understood as the purification of household waste. There will

"Eat" into waste, "vomit" out of fuel, and become a "artifact" that turns waste into treasure in Zhengzhou, Henan. The Industrial Solid Waste Disposal System produced by AIShred can "eat" 20 tons of C&I waste in one hour and produce preparations Popular alternative fuel RDF/SRF. So what craftsmanship does AIShred make "people suspected" and make the waste into the "fragrant" of the fuel industry? Waste is an abandoned item that loses its value and cannot be used. It is the ultimate part of the material cycle. The widely used waste treatment methods today are sanitary landfills, high temperature compost and incineration. However, most of the industrial waste incineration contains considerable heat values, and directly landfills or incineration undoubtedly causes waste of resources. Now, this industrial solid waste disposal system located in Zhengzhou, Henan can effectively use general industrial solid waste such as leather edge, cloth edge corner, waste paper residue, waste fabric, waste plastic, etc., and

Industrial waste realizes its final value in factory production and is hidden in the corners of factories because there is no way to be discarded directly, plus the high price of disposal. In the "double carbon" target, high coal prices, cement companies increasingly hot competition and other comprehensive background, alternative fuels and co-disposal has received more and more attention, the wave of industrial solid waste preparation of alternative fuels was born. AI Shred environmental protection alternative fuel preparation technology can turn industrial solid waste into reusable "coal" energy, industrial waste disposal is no longer a problem!What are the categories of industrial waste?Industrial waste is divided into cloth and leather trimmings from garment factories and shoe factories, waste residue from paper mills and twisted rope braid material, fiberglass trimmings, waste rubber and plastic, etc. From the perspective of resource recycling, these wood materials to leather trimmings, they can all be

Derived fuel has the characteristics of high calorific value, stable combustion, easy transportation, easy storage and low secondary pollution, which is widely used in drying engineering, cement manufacturing, heating engineering and power generation engineering. RDF raw materials mainly come from domestic waste, industrial waste, organic waste, etc. It contains waste paper, hard plastic, metal, glass, wood, rubber and other substances. The coarse shredder and fine shredder meet the crushing requirements of RDF, greatly simplifying the RDF treatment process and realizing high economic and ecological value. Equipment Configuration The crushing of this high mixture of materials places high demands on the crushing technology. The stable operation of the shredder requires high performance alloys and high reliability of the whole machine. This type of crushing requires a machine capable of handling hard materials such as metals and plastics. To obtain a high quality RDF, the following steps need to be performed:

With the development of the economy, the number of waste textiles eliminated by residents has gradually increased, sporadic treatment cannot meet the production requirements, and a sustainable industrial waste system is urgently needed to help us explore together. Today, let's talk about the energy recovery of waste textiles. Because of the addition of comprehensive materials, the thermal value of the waste textiles is very good and the combustion is good. Therefore, it has great potential for incineration power generation and cement kiln. As the energy recovery of waste textiles, we must use industrial waste shredding to deal with the production line. Only through the disposal of this production line can we meet the energy recovery of waste textiles. So what is this industrial waste system? First of all, the core equipment of this system is shredding+sorting, and the connection system is conveying. The purpose of broken is to fully shatter, shear and crushed materials. First, ensure that the material can be

Internationally, Refuse Derived Fuel (hereinafter referred to as "RDF") is regarded as a new way of waste harmless, recycling and reduction. It has been widely used in cement, power generation and other industries. It is green, environmentally friendly, high quality and low price Alternative fuels (SRF/RDF) are the new trend of the future. The preparation of waste-derived fuel RDF is not limited by site and scale. It is suitable for small and medium-sized waste treatment plants to be scattered and manufactured, and then collected for power generation, which is conducive to improving the scale and efficiency of waste-to-energy power generation. Converting waste to waste-derived fuel (RDF) serves two purposes: it can reduce the amount of waste sent to landfills, thereby solving problems in the waste field, and it can supply large coal-fired power plants, waste incineration plants, cement plants Provides a large number of alternative fuel RDF. AIShred RDF&SRF Alternative Fuel Achievement PathAIShred has

Engineered fuel is a kind of alternative fuel produced by processing and blending construction and demolition material, and/or select industrial and/or commercial byproduct material streams including: plastic, paper, paper mill contraries, paper fiber, cardboard, textiles, carpet, and rubber.Waste to Engineered Fuel Processingpre-screening of potential customers' material before it is received;feedstock acceptance practices to ensure a primarily wood-based product and removal of materials that may have high contaminant levels;removal of metals and fines;manual sorting to remove residual contaminated material;shredding to improve the fuel characteristics of the material;final screening to ensure consistency and low ash levels and improved combustion in the fuel.AIShre Shredding Solution in Waste-to-Fuel ApplicationShredding is the most important stage in Waste-to-Fuel applications, as it imporve the fuel characteristics. AIShred offers two kind of shredders for waste to engineered fuel application: the

Alternative fuel RDF(refuse derived fuel) or solid secondary fuel is a fuel obtained from waste. RDF contains high-calorie waste components such as plastic, paper, cardboard, textiles, rubber, leather, wood, etc.RDF can be used as main or supplementary fuel in furnaces of cement plants, thermal power plants, metallurgical furnaces. The calculations performed showed the expediency of replacing gas or coal with RDF in the production of cement.The production of cement requires significant energy costs due to the need to maintain the temperature in cement kilns above 2000°C. For each ton of cement produced, typically 60-130 kg of fuel oil, or its equivalent (natural gas, coal), and about 105 kWh of electricity are required. On average, energy, fuel and electricity costs account for up to 40 percent of cement manufacturing costs. Therefore, it is advisable to use alternative fuels obtained from waste in production processes in order to reduce the use of traditional fuels and raw materials by replacing them with

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 up to 100% by alternative fuels. Nevertheless, there are certain technical limitations like the calorific value, the moisture content, and the content of side products like trace elements or chlorine. The calorific value of most organic material is comparatively low (10 – 18 GJ/t). For the main firing of the cement kiln an average calorific value of at least 20-22 GJ/t is required, meaning that high calorific alternative fuels are mostly used in the main firing. Waste tyres can be used as a fuel in cement kilns. Waste

Since the beginning of the 21st century, more and more waste has been generated. In order to cope with the threat to the environment caused by the increase in waste, people have begun to use waste as fuel that can be burned in boilers for power generation or heating. We divide the fuel from waste into RDF, TDF, SRF according to different components and processing method of the waste. RDF(Refuse-derived fuel) is a fuel produced by sorting and shredding combustible materials contained in municipal solid waste (MSW) and industrial waste. Compared to fossil fuels, RDF is more affordable, abundant, and environmentally friendly. SRF(Solid Recovered Fuel) is a fuel produced by drying, filtering, and shredding solid waste, It is usually produced to meet the standards in Europe. The EN 15359 document gives the specifications for classifying SRF. Unlike RDF, SRF is a more refined material that is slightly more efficient than RDF, though it takes a more advanced process to make the fuel. TDF(Tire-derived fuel) is a

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 remain at the waste sorting complexes after the extraction of all useful recyclable materials, is one of the most environmentally friendly and effective solutions to this problem. The use of alternative fuels from municipal solid waste (MSW) in cement production will help global achieve environmental goals.Waste Disposal in the Production of CementLimestone, clay and thermal energy are needed to make cement. The cost of the latter is 30% of all production costs. The cement industry uses a variety of fossil fuels to

Floating marine debris pollutes the ocean, causing the death of marine life, coral reefs, etc. The "garbage islands" formed by the gathering of them not only block the air route, but also have a huge impact on the tourist country. Now is the time to have to deal with marine waste. The good news is that most of the floating ocean debris is combustible and can be shredded to make alternative fuels, this is a carbon-reducing fuel that can be used in waste-to-energy plants or cement kilns. What Kind of Shredder is suitable for Process Marine Waste? We recommend the use of dual-shaft shredder and single-shaft shredder to deal with marine garbage. The dual-shaft shredder can process the garbage into about 50mm to 200mm in size, and the single-shaft shredder can reduce the garbage to about 10mm. AIShred Lightweight Waste Special Shredder AIShred has developed a shredder specially used for processing light waste. It has excellent energy consumption ratio and high wear resistance, especially suitable for processing

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 carbon emissions, the waste-to-fuel technology has become more and more mature, and many cement kilns have begun to use municipal solid waste or industrial and commercial waste as alternative fuels.Substituting Coal and Petcoke with Alternative fuelsCoal and petcoke, two of the most carbon-intensive fuels, are typically used to heat cement kilns. The substituting coal with lower-carbon fuels offers the greatest short-term potential to reduce CO2 emissions in the industry. Most alternative fuels have a lower carbon

Waste-to-Energy (WtE) plants treated around 420 million tons of waste per year worldwide1. Thanks to the production of energy through waste incineration, WtE plants allow materials to be recovered and recycled. decrease the amount of waste sent to landfills and reduce the proportion of fossil fuels used as a source of energy production.Waste to RDFWaste shredding plant processes overproduction, bulky waste fractions, large packaging and unsorted commercial waste by transforming them into waste-derived fuels (RDF) in various qualities. These fuels can be sent to waste incineration plants, cement plants, steel plants, etc., to obtain certain economic benefits.Waste to Fuel PelletBy pelletization we mean the process of transforming waste, generally into pellets, to make it usable for other applications. To be transformed into pellets, the waste must first be shredded, crushed or pulverized. The materials thus obtained are then processed in a rotary drum or disc pellet machine with the aid of a binding agent,
