The mobile granulator for agricultural waste

The granulateur mobile h-énergieis the farming equivalent of the Batmobile, designed to fight the enemy – waste – in the field. But the vehicle isn’t the result of a comic-book writer’s imagination: it was created by three award-winning craftsmen, specialists in heating, electricity and metalwork, from the Alsace region of northern France. Its efficiency, too, is very real. The big white lorry is a mobile convertor of agricultural waste: residue straw from maize, rape and spelt, vine shoots and even branches lying around in fields. The h-énergie granulator travels to a site and turns the waste, which would otherwise have been destined for the bin, directly into pellets to fuel stoves and boilers. And it does its job in record time, producing around a tonne of pellets per hour depending on the type of waste.The h-énergie granulator travels to a site and turns the waste, which would otherwise have been destined for the bin, directly into pellets to fuel stoves and boilers
“The idea is to recover raw materials and turn them into pellets on site, so that owners can use the raw material for heating and reduce their energy bills,” explains Xavier Rémond, co-inventor of the special lorry. Inside the big white vehicle, the agricultural waste passes through a shredder, two grinders, and another machine that shapes it into small, compact pellets.
Award-winning
The mobile granulator’s appeal lies in the fact that it is both cost-efficient and eco-friendly. The way it produces fuel costs half the price of using gas or oil. Moreover, the lorry is a means of decreasing the amount of waste farmers throw away, using renewable energy instead of fossil fuels, and reducing transportation and CO2 emissions as a result. The invention was awarded the “President of the Republic” prize in the latest Lépine competition. The mobile granulator is already up and running with one unit in service, and countries such as Australia and Canada have shown interest in it. This white lorry could certainly go a long way from the fields of Alsace.
