Raw Material Substitution Cembureau

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.

Home Cembureau

Over the past decades, the cement industry has invested heavily in four main levers to reduce direct CO 2 emissions: Thermal Efficiency, Fuel Substitution, clinker substitutes and novel clinkers and carbon capture.. Breakthrough technologies further contribute to lowering clinker related emissions.

The story of cement manufacture Cembureau

CEMENT MANUFACTURE. The cement-making process can be divided into two basic steps: Clinker (the main constituent of cement) is first made in a kiln with gas up to 2000°C, which heats raw materials such as limestone (calcium carbonate) with small quantities of other materials (e.g. clay) to 1,450°C.

Green Deal CEMBUREAU

The cement industry is a leader in the circular economy, through the use of a variety of waste streams as alternative fuel and raw materials in our production processes and down the value chain, where concrete is a fully recyclable product. Read more about our role within a circular economy here.

Raw Materials Substitution an overview ScienceDirect

Raw material substitution or elimination is the replacement of existing raw materials with other materials that produce less waste, or act as a non-toxic waste. Using high-solids coatings: Traditional sealers and topcoats are 20% solids or less, meaning that 80% or more of the coating evaporates and is wasted even if the transfer efficiency (TE

MERCURY IN THE CEMENT INDUSTRY

Mercury enters in the cement manufacturing process as a trace element with the raw materials and the fuels. The mercury content of natural raw materials varies between individual raw material deposits and even within the same deposit. In fuels, the amount of mercury can vary in a similar way, depending on the fuel type and the fuel source.

Critical raw material substitutes Circular Economy Guide

Critical raw materials are minerals that: Have high supply risk due to high concentrations in specific countries; Are vital for key sectors in the economy; Do not have economically viable substitutes; These elements are not “critical” due to low supply available in nature. Because of supply restrictions and demand pressures, dependence on

The potential for co-processing. A recent study conducted by CEMBUREAU / Ecofys shows that co-processing of waste in cement kilns is already being widely employed across the EU, but that the potential for further uptake remains large.. Increased co-processing rates across the member states can further contribute to overcoming challenges such as climate change, waste

CEMBUREAU & ETRMA call for support of combined waste

The co-processing solution provided by our sector is somewhat unique in that both material recycling and energy recovery take place at the same time. The mineral content of waste serves as a raw material for the production of clinker (recycling), while the energy content provides part of the energy needed for clinker production (energy recovery).

The cement industry is also adapted for a circular economy through the application of alternative raw materials and clinker substitution. For instance, clinker can be easily replaced with materials generated as by-products of other industries such as fly ash from thermal power plants and blastfurnace slag.
