Methanisation plant reduces CO2 production

Together with agricultural neighbours, Prestia has formed an association called Energiculteurs de l’Oust, which exploits a methanisation plant. This ‘shit factory’ transforms agricultural waste into gas that is used to produce electricity, which is delivered to the grid, and heat, which is used to heat the pre-treatment baths of Prestia SBG’s galvanisation plant, leading to a CO2 reduction of 274 tonnes.

Switching to electric company cars

In our company car policy for the Netherlands, we have already switched to fully electric, and Belgium followed in 2022. Depending on the infrastructure for charging electric vehicles in the different countries, our other Business Units will follow as soon as possible or switch to hybrid as an intermediate step.

Green hot-dip galvanising

Rotocoat stopped adding lead to its zinc baths, and Rezinal developed a low-lead alloy. As the importance of green production increases, Rotocoat is collaborating with Zinkinfo Benelux (ZIB) on developing a blueprint for the 2035 galvanisation plant using green hydrogen. In collaboration with the Dutch employers’ organisation FME, Rotocoat joined the sixth cluster, which encompasses a wide range of industries with unique characteristics that want to cooperate on themes regarding the process and chain efficiency related to sustainability goals.

Electric zinc furnace

Prestia has the largest zinc kettle in France, which is equipped with an electric furnace.
