Heading sustainability


Emissions reduction

The main emissions related to the production of clinker, other than CO2, are those of dust, NOx and SO2.

of specific dust emissions from 2017

Dust emissions from the kiln system has been reduced thanks to the installation of new filtration systems.
Nitrogen oxides (NOx), deriving from combustion in the clinker kiln system, have been reduced with abatement systems using urea or ammonia solutions and new-generation Low-NOx burners.


of specific NOx emissions from 2017


of specific SO2 emissions from 2017

Sulfur dioxide (SO2) emissions, coming from sulfur contents of natural resources and fuels, are controlled imposing strict limits to sulfur content for purchased raw materials and fuels.
