Degassification and environmental improvement
|
Locally: - Minimising smells, since the biogas is captured and treated by means of controlled combustion at a high temperature in the engines.
Globally: - Minimising the contribution to the emission of greenhouse gases generated during the biodegradation of municipal waste in the controlled disposal site. Treatment of around 50 million m3/year of methane is equal to a reduction of around 600,000 t/year of CO2.
- Generating around 100 million kWh/year reduces emissions of carbon dioxide from consumption of fossil fuel in power plants by between 50,000 and 110,000 tons/year.
Both these effects combined are equivalent to planting around 17,000 hectares of forests. Garraf natural park has 12,820 hectares of forests.
