Study / Decarbonisation of cooking and drying processes

Companies are seeking to reduce their environmental impact, in particular by cutting their greenhouse gas (GHG) emissions. This drive is supported by the objectives
set by France as part of the National Low Carbon Strategy (SNBC), of -81% of GHG emissions for the industrial sector. One of the main levers for action is work on manufacturing processes.

This study focuses on the decarbonisation of drying and baking processes, for which three types of solution are being studied: energy efficiency, electrification and renewable and recovered energy.

The aim of the study is to examine the application of these different decarbonisation solutions in three application cases and to compare the results up to 2050 from an energy, economic and environmental point of view.

The applications studied are the drying and firing of roof tiles, the drying and polymerisation of a powder paint line, and the kilning of barley malt.

The study shows that all these solutions offer significant reductions in greenhouse gas emissions. To go further in reducing GHG emissions linked to certain processes or in certain specific cases, CCUS (Carbon Capture, Utilisation and Storage) solutions may prove necessary.
