BIOGAS AND ELECTRICAL GENERATION
Any controlled waste deposit, in which there is an important disposition of organic matter, generates a volume of emission of gases that come mainly from the anaerobic digestion of the deposited materials.
This is what is known as Biogas, esentially composed of methane (CH4) and carbon dioxide (CO2); although its composition also depends on several factors such as: amount of waste deposited, technical characteristics of the deposit, exploitation system used, geographical location, etc. These gases contribute significantly to the "Greenhouse Effect" in the atmosphere.
The combustion of biogas implies a significant reduction of emissions of these greenhouse gases. A methane molecule is 21 times more dangerous than one of CO2, and its release into the atmosphere causes different environmental impacts, as well as serious risks to public health.
Energies of the Future
This has prompted TECMED to find an effective way to contribute to the control and reduction of greenhouse gases, taking as an example one of the projects, by site, the largest in the world, the Loma los Colorados Sanitary landfill in the city of Santiago of Chile, an immense site where an average of 6,500 tons of urban garbage is received in daily operation.
The selected strategy, as the optimal solution, consists in the capture, treatment and combustion of the gases emitted to neutralize them in the form of electric and heat energy.
