As organic waste experts, we bring together waste producers and short-circuit plants to recycle waste and benefit the country as a whole.


Progress guarantees performance

Whether you’re looking to modify existing equipment to optimise your plant (to save time or increase productivity), or to increase its power by inputting more feedstock, don’t hesitate to book an appointment with one of our technicians to talk through your options.

Our solutions

Optimise power

Install a cogeneration motor to increase power and generate more energy.

Optimise production

Upgrade or install an agitator to increase efficiency.

Seal the storage pit

Recover more gas, limit gas exchanges and reduce odours.

Protect your equipment

Install a sulphur trap to capture H2S (sulphur) and protect equipment.

Increase the tonnage

Modify the feed system to diversify and increase the amount of feedstock.

Produce more gas

Install a heating system in the tank to increase its digestive power.

Upgrade to standards

Change or update parts so that your plant meets new standards.

Optimise energy use

Install low-energy equipment and photovoltaic panels in self-consumption, add an insulating membrane to the gasometer to avoid heat loss.
