Cogengreen provides sturdy, tried-and-tested methanation units supplied with contractual performance guarantees.

Effluent valorisation

Our units upcycle the effluents (liquid and semi-solid manure, crop waste) and the by-products found on the farm to convert them into electricity, heat and digestate.

Sound experience

Our methanisation stations are the result of 15 years’ experience of methanisation at Cogengreen and its partners..

What is biomethanisation?

A biomethanation unit makes it possible to produce methane from decomposing organic matter: liquid or semi-solid manure, agricultural and agri-foodstuffs waste, crops. This methane is upcycled in a cogeneration unit.

The waste is converted into electricity, heat and digestate. Digestate is the waste material remaining after methanation: water, fibres, mineral elements. It is a high-quality fertiliser.

Schéma Cogeneration


Several types of units

  • Small farm units (20 to 200 kW) that mainly process liquid and semi-solid manure from the farm.
  • Larger units (600 kW and over) that process liquid and semi-solid manure from nearby farms, crops and waste from the agri-foodstuffs industry.

The units that we supply are intended mainly for cattle and pig breeders.
