Biogas flaring

After having closed a landfill or a cell exploitation, the biogas, produced by the garbage, can be valorized. Tests on the presence of biogases and simulations of quantities produced are done to determine what is the best solution to put in place. The simple flaring if the quantity is not sufficient for a better valorization (the CO2 produced is about 21 times less harmful in terms of greenhouse effects gas than CH4 methane). The production of electricity or hot water by addition of a gas engine. 6 Consult participated in the flaring plants building on the different sites of Tunisia. The different stages consist in : The wells drilling; The artificial covering if necessary; The gases transportation network; The flaring itself.
