Renault Tangier plant: successfully meeting the “zero carbon emission” challenge

Tangier (Morocco)

Olive cake: the biomass solution

Interview: three questions for Christophe Doublet, Director of Veolia Industries Global Solutions in Morocco

What does the “Biomass” solution implemented in the paint workshop involve?

The process implemented in this workshop requires hot water at a certain temperature and a moisture content that must be scrupulously respected. The hot and superheated water (120°C) are produced by three boiler rooms, each with a power of 6 MW. They consume local biomass in the form of olive cake. Each year, 20,000 metric tons of this residue from the olive industry supply the plant’s three boilers.

Why was olive cake chosen?

We used to use olive stones and argan husks but olive cake has something of an economic advantage, because it is made up of the skins, residue of the flesh, and stone fragments. What’s more, as it is an abundant resource, we are guaranteed not to run out of fuel in the long term.

How does it offer better calorific performance?

The oil content must remain under 1% to ensure that the boilers continue to run smoothly, hence the need to turn to industrial oil mills that guarantee the stability of the moisture and oil content.
