Webinar on Best Available Techniques (BAT): Insights from the Cement Production and Waste Incineration Sectors - Georgios Chronopoulos

This webinar is the third in a series on industrial pollution prevention and control. It explores how Best Available Techniques (BAT) are used to reduce industrial emissions in the cement production and waste incineration sectors. Drawing on cross-country insights from OECD reports, Activity 6: Cross-Country analysis of selected sectors for comparison and Activity 7: Cross-Country Analysis of selected BREFs for Iron-Steel, Paper-Pulp and Waste incineration sectors, the webinar sheds light on significant environmental challenges, highlights shared and sector-specific emission control techniques and discusses the potential for harmonising BAT implementation globally. The findings are based on reviews of BREFs from the European Union, the United States, China, India, Korea and the World Bank.

BAT conclusions for the cement industry (1/3)
General BAT conclusions:
-EMS (Environmental Management System)
-Noise
BAT conclusions for the cement industry
•General primary techniques (process control optimisation, gravimetric solid fuel feeding system,
selection and control of all substances entering the kiln)
•Monitoring (of process parameters and pollutants, continuous or periodic)
•Energy consumption
•Use of waste (waste quality control, waste feeding into the kiln, safety management for use of
hazardous wastes)
•Dust emissions (diffuse emissions, from dusty operations*, from kiln firing processes*, from
cooling and milling processes*)
•Gaseous compounds: NO
X*, SO
X*, CO and CO trips minimisation, TOC, HCl*, HF*
•PCDD/F*, metals (Hg*, Σ(Cd, Tl)*, Σ(As, Sb, Pb, Cr, Co, Cu, Mn, Ni, V)*)
•Process losses/waste generation
*: BAT-AEL established

INCITE
October 2025: 2
nd
sectoral workshop (Cement, lime and
magnesium oxide production)
INCITE sectoral workshops will review and help to fast-
track the uptake of innovative techniques with the
potential to accelerate the transition towards a greener
and more competitive industry, starting with energy-
intensive sectors.
For 2 days (30-31 October) participants will review key
European and global industrial projects aiming to achieve
zero pollution, climate neutrality, increased resource
efficiency and circularity in the cement, lime and
magnesium oxide sector.
