Cutting NOx emissions: strategies for a cleaner future

The cement industry plays a pivotal role in global infrastructure development; however, it faces increasing scrutiny for its environmental footprint, including greenhouse gas emissions. Nitrogen oxides (NOx) are particularly concerning among the various pollutants they generate due to their role in forming smog and acid rain and contributing to respiratory issues, making their reduction a critical priority for sustainable operations. NOx emissions arise primarily from the hightemperature kilns required in cement production, making them a significant challenge to mitigate. As global regulatory frameworks tighten and stakeholders demand sustainable practices, the industry invests in innovative solutions to reduce emissions. This article explores the technologies, strategies, and challenges in achieving meaningful NOx emissions reduction in the cement industry, paving the way for cleaner efficient production with environmental responsibility.
