Territorial methanization to the help of communities
Territorial methanization can be a powerful ally for communities in the management of bio-waste. Major subject since Grenelle 2 of the environment, the time for concrete action has come. The energy transition law for green growth establishes new obligations in reducing waste.
Methanization, an innovative process for recovering organic waste from territories:
Today, we can produce green energy from organic materials such as livestock effluents or household waste, thanks to methanization, a proven technological solution in the field. Advanced sorting techniques isolate organic matter from the rest of the waste, it is then sent to a digester to be methanised. In the absence of oxygen, organic matter decomposes and simultaneously produces gas, convertible into electricity by combustion, and a digestate which can be used as compost.
So the methanization is the most successful process for recovering organic waste. It allows a complete transformation of waste for the benefit of the whole community. From an economic and ecological point of view, the installation of an anaerobic digestion unit on the territory of a community presents a very positive outcome.
First, it allows a close outlet for collection, the waste will be treated and recovered as close as possible to the place of production. This is already good for the carbon footprint. Next, biomethane is a renewable energy that can be used directly by users of gas networks. The recovery of the biomethane thus produced is twofold: use as fuel in public transport and the surplus is reinjected into the gas network for other uses. Finally, the methanization process produces an organic amendment, the digestate, which allows organic matter to return to the soil, thus promoting the regeneration of the quality and fertility of agricultural land.
This process generates around 3.5 million m3 of biogas per year. 25,000 tonnes of treated waste allows the production of 8,000 MWh of electricity, equivalent to the annual consumption of 2,700 homes. The biomass thus recovered makes it possible to avoid the emission of 2,000 tonnes of CO2 equivalent per year. Organic materials not degraded during anaerobic digestion, which represent 7,000 tonnes per year, are reused as compost by local agriculture.
Reducing greenhouse gas emissions, saving energy, creating jobs… There are many reasons why communities are embarking on methanization. So, almost everywhere on the territory, methanizers are pushing and creating a virtuous economy.
