Cement production emits environmental pollutants, mainly in the form of atmospheric emissions such as particulate matter (PM), nitrogen oxides, and sulfur compounds, which are subject to national legislation and local regulations. There are also low levels of dioxins and furans, volatile organic compounds, and other heavy metals.

For this reason, CEMEX is committed to ensuring compliance with air quality regulations through comprehensive, continuous, and discontinuous systems that monitor our generation of primary and secondary emissions.

CEMEX Air Emissions Management

Air Emissions: Major emissions, particulate matter (PM), nitrogen oxides (NO_x), and sulfur compounds (SO_x), are released as part of the cement productions process. Minor emissions -including dioxins and furans, volatile organic compounds, and other heavy metals- are released in very small or negligible quantities.

Continuous Emissions Monitoring System (CEMS): Allow our operations to control and ensure compliance with air quality regulations.

Online Visualization Tool: In 2020, we launched a new industry-benchmark online tool that allows operators and management teams to closely analyze major emissions, improve monitoring abilities from kilns with CEMS installed, and strengthen emissions performance.
