Cement is the main ingredient of concrete, which is the most common building material in the world. The cement industry is one of the biggest CO2 emission producers mainly due to the huge production capacities and calcination process, which is an important part of cement production. Cement manufacturers need to monitor these emissions continuously according to local emission regulations. Read about our solutions for the cement industry.

Waste Incineration in Cement Kilns

The cement industry is actively seeking to increase the use of alternative fuels for cement production. Both to decrease energy dependence on conventional fossil fuels and to mitigate negative environmental impact.

One of these alternatives is waste-to-energy. Many cement plants generate energy through the incineration of waste. Hazardous waste can be incinerated at specific waste-to-energy plants but also at plants with permission for co-incineration of waste.

The downside is that waste incineration in cement kilns releases toxic emissions into the air containing mercury, lead, cadmium and thallium, and other heavy metals.

Cement Plants’ Emissions Monitoring

Cement plants in general follow their own emissions monitoring standards. In cement plants, the flue gas generally includes carbon dioxide (CO2), nitrous oxides (NOx), sulphur dioxide (SO2), mercury and dust. SO2 emissions are mostly derived from the raw material, whereas more than half of the CO2 emissions are coming from the limestone calcination process and the rest are related to the used fuel and efficiency of the combustion process.

If a cement plant acts as a co-incineration plant and incinerates waste, it is subject to strict emissions regulations. All waste burning plants have to meet at least the stringent emissions limit, monitoring, waste reception and treatment standards brought in under the Waste Incineration Directive (2000/76/EC), which has been recast into the Industrial Emissions Directive (2010/75/EU).

The Waste Incineration Directive subjects co-incineration plants to the continuous measurement of for example hydrochloric acid (HCl), hydrogen fluoride (HF) and mercury (Hg). Measuring of total organic carbon (TOC) is also mandatory.

Our Solution: Monitoring Systems for Demanding Measurements

Both of our continuous emissions monitoring systems (CEMS) are certified systems designed for demanding emission monitoring measurements.

We also have a sampling system for dioxin and furans:

  • The Dioxin Monitoring system GT90 Dioxin+ MCERTS certified device designed for long-term sampling of dioxin emissions and furans in conformity to the European standard EN1948-1 and EN15267. The system represents the cutting-edge technology for dioxin sampling and fulfills all the requirements of the dioxin measurement standard.
