Glossary and abbreviations

Energy mainly produced from biomass and which can be used as a fuel or heat.

Gas resulting from the biological degradation of organic matter in the absence of oxygen. This gas contains a high proportion of methane (50%) and so has a high calorific and energy potential. In our activities, it is produced at landfills (landfill gas), in anaerobic digesters and in wastewater treatment plant digesters. It has to be collected to prevent odor problems and its contribution to greenhouse gas emissions. Once collected, it can be used as a source of energy to replace fossil fuels.

All plant and animal matter along with the associated organic waste.
