Global cement emissions standards

Amid ever-decreasing SO 2 emissions limits, cement plants can employ a number of processing and technical measures to reduce their emissions. Firstly, producers can move to low-sulphur coal sources or move away from using coal as a primary fuel. Some alternative fuels, for example tyres, can also include high levels of sulphur impurities.

In general, there are five stages to completing the cement production process. These are the raw material preparation stage, raw mix and milling stage, clinker forming stage, cement milling stage, and packing and delivering stage. Each stage comprises many parameters that influence the production system.

Carbon Capture in the Cement Industry: Technologies, Progress, …

The cement industry is likely to play a role in reducing greenhouse gas emissions to combat anthropogenic climate change. Many decarbonization pathways suggest that direct specific emission levels of around 350 – 410 kg CO 2 /t cement will be required. However, increasing clinker substitution, alternative fuel use, and thermal energy efficiency can only lead to specific …

New cement technologies

New cements will therefore most certainly first take into account higher amounts of main constituents besides clinker which show pozzolanic or latent hydraulic properties. Artificial materials that originate from natural or industrial resources but require additional thermal treatment and/or activation may also have a role to play.
