Introduction. This fact sheet summarizes the European Commission (EC) February 2007 By-Products Definition Communication (PDF) (13 pp, 177K, About PDF).The Communication is designed to provide businesses and regulators with guidance in deciding when leftover materials from industrial production processes should be classed as waste and when …
Replacing the clinker in our final cement products with alternative mineral components reduces the carbon intensity. The main reduction will not only come from recycling construction and demolition waste or byproducts from other industries but also by investing in calcined clay facilities and developing novel cements with new binders.
The clinker emission factor is the product of the fraction of lime in the clinker multiplied by the ratio of the mass of CO2 released per unit of lime. This is illustrated below: ... Furthermore, the amount of clinker in other types of cement, such as blended and natural cement, is highly variable and difficult to estimate.
clinker production, the scope will include the generation and subsequent use in the kiln. Only waste streams are considered for alternative fuels. Since the alternative fuel is a by-product or waste, its generation is excluded from the analysis. The end-of-life disposal of these waste streams is considered. In terms of clinker production ...
Incompatible products: Do not use aluminium containers due to incompatibility of the materials. 7.3 Specific end use(s) Clinker is used for the production of common cements or other hydraulic binders. In general such final products have to be low in water soluble Cr(VI). Typically, the final products contain a chromate reducing agent. 8.
While China was the main force behind the global increase, the clinker-to-cement ratio has also risen moderately in a number of other regions. Conversely, the clinker-to-cement ratio falls 0.8% per year to a global average of 0.65 by 2030 in the Net Zero Emissions by 2050 Scenario, owing to greater use of blended cements and clinker substitutes ...
The utilization of waste materials from the palm oil industry provides immense benefit to various sectors of the construction industry. Palm oil clinker is a by-product from the processing stages of palm oil goods. Channelling this …

Other authors (8– 11), reveal satisfactory results on the use of paper sludge as secondary material in clinker production. In this regard, it should be taken into account that in the production of clinker for Portland cement, the extraction of large quantities of raw materials (mainly limestone and clay) is required.
On the other hand, in our previous study on the uptake (Xi et al., 2016), clinker ratio values from the historical literature, including the default value of 0.75 (as the lower bound) recommended by the Intergovernmental Panel on Climate …
Examples of the waste materials commonly used as alternative fuels include used tyres, animal residues, sewage sludges, waste oils and other …
problem of waste management to significant level but also reduce use of fossil fuel. In addition to energy recovery, there is also a corresponding saving relevant to CO2 emissions released into the atmosphere, since waste replaces other fossil fuels producing greater CO2 levels [7]. Fig 1.3: Cement Industry Share in CO2 Emissions [8].
Clinker is quicker to assemble, easier to use and offers better protection than market alternatives. Its flexible nature caters for varying bottle sizes so that one size can fit all. With options to ship 1, 2, 3, 6 and 12 bottles or individual magnums, Clinker offers the versatility and flexibility to use across the drinks industry.
Examples of the waste materials commonly used as alternative fuels include used tyres, animal residues, sewage sludges, waste oils and other types of waste derived from industrial and municipal ...
The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was …
Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln. ...
Waste glass as an aggregate replacement for the use in mortar or concretes. Another viable option for the utilisation of waste glass in cement-based materials is for the replacement of fine and coarse aggregate. The use of natural aggregate promotes the depletion of sources such as beaches and quarries which cannot be sustainable.
residual waste from industrial operations, such as boiler slag, clinker, and fly ash. Hazardous wasteshares the properties of a hazardous material (e.g. ignitability, corrosivity, reactivity, or toxicity), or other physical, chemical, or biological characteristics that may pose a potential risk to human health or the environment
contaminated soil, waste from road cleaning and other iron-, aluminium-, and silica-containing wastes or by-products, such as coal fly ash and blast furnace slag. The chemical suitability of recycled materials is important to ensure that they provide the necessary constituents for the formation of clinker. The use of alternative raw materials ...
Oss, 2017), it is the production of clinker that leads to pro-cess CO2 emissions, and the amount of clinker in cement varies widely. With no available source of clinker produc-tion data for all countries, other options must be considered. The direct use of cement production data without adjust-ment for clinker trade or clinker ratios that vary ...
Energy Use in the Cement Industry in North America: Emissions, Waste Generation and Pollution Control a EXECUTIVE SUMMARY This paper examines issues related to the use of energy inputs in the manufacture of cement clinker and cement in Mexico, Canada and the U.S since 1990 and particularly
The agriculture industry is one of the main industries in the Southeast Asia region due to its favourable conditions for plantations. In fact, Southeast Asia region is the world’s largest producer of palm oil and coconut. Nevertheless, vast plantation of these agriculture products leads to equally large amount of waste materials emanating from these …

in the clinker-to-cement ratio and the use of alternative fuels is growing. As a result, the overall GHG intensity of cement manufacturing in Canada has decreased by 13%. However, the immediate opportunities for further progress on efficiency are limited. Improvements to the clinker-to-cement ratio are largely tied to standards and building codes,
