At the beginning of the 21st century, awareness of the impact of human activities on the environment has never been so rapid: greenhouse gas emissions into the atmosphere, soil depletion, water and air pollution are now well documented.


Anaerobic digestion, a process that transforms organic matter into biogas to be used as energy, is a convergence of several environmental issues. First of all, it is the first lever for greening the fossil fuel gas currently circulating in the networks. Responsible for 20% of greenhouse gas emissions in France, this fossil fuel gas will have to be 100% replaced by green gas coming in particular from anaerobic digestion in the next 3 decades. Biomethane produced from anaerobic digestion also plays an increasingly important role in reducing polluting emissions from the heavy vehicles and ship transport sector in the form of bio-NGV.


Beyond the energy dimension, anaerobic digestion is a key tool in the agro-ecological transition: it reduces spontaneous methane emissions from livestock manure and reduces the use of synthetic fertilisers by replacing them with digestates from fermentation. In combination with intermediate crops, it can be used to reduce water pollution and also as an additional means of storing organic carbon in soils.


Convinced of the services that anaerobic digestion must provide to society, and aware of its limitations, the KEON group has set itself the task of contributing to the development of virtuous anaerobic digestion projects in the service of French territories and internationally. By selecting the projects it supports, and ensuring their proper implementation over their entire lifespan, KEON teams are committed to making a positive contribution to the transition of our energy and agricultural model.
