P1000254Today, all communities are confronted with an increase in the volume of waste. Despite campaigns encouraging recycling, waste treatment is still a large burden. And yet, waste transformation industries exist and offer a real financial support to public services for the elimination of waste.


Biomass 

The term "biomass" includes all organic matter that can release energy, either through direct combustion or after a transformation step. These processes are used more and more for the recovery of waste from agriculture (manure, propagation waste, etc.), the food industry (grape pumice, grease, etc.), sylviculture (green waste, palettes, etc.), as well as household waste.

In France, in 2006, heat production from the biomass industry was 8.8 Mtoe (excluding biogas).
Following the Environmental Roundtable, the target set for heat production from biomass is an increase of 6.2 Mtoe by 2020 (source: Ministère de l'Ecologie).

 

 

 

Quadran, through its subsidiary Méthanergy, is active in 3 biomass recovery industries:

• Landfill biogas 
From waste storage sites, biogas is a combustible gas produced during the decomposition of organic materials. Biogas contains 35% to 55% methane (CH4). Recovering it enables the production of electricity and heat without using fossil fuels and significantly reduces greenhouse gas emissions.
Every ton of waste that is buried at a waste storage site naturally releases between 80 and 200 m3 of biogas that can be captured and collected to be transferred to the energy transformation unit. 

 

Biogas from anaerobic digestion 

Anaerobic digestion consists in controlled fermentation of organic waste in watertight tanks called digesters. This process generates:

biogas that can be transformed into electricity and heat, the quantity of which depends on the type of waste used,
a wet product rich in partially stabilized organic material, called digestate, that can be used on agricultural land.

 

Biomass Cogeneration 
Cogeneration consists in burning biomass (wood, agricultural waste, wood waste, etc.) in a boiler to produce electricity and heat or coolness.

Points of Reference

At the end of June 2019, Méthanergy operates 10 biogas recovery units on non-hazardous waste sites, 
totaling 12 MW.

Quadran positions itself on the creation of anaerobic digestion units from organic and agricultural waste and on the recovery of landfill biogas.
