Councillor for the Environment of the City of Lorca, Melchor Morales, has introduced a new system of power generation degassing and pouring vessels of the Waste Management Centre of Lorca would allow the installation of generator sets up to 875 kilowatts of electric power through conversion of biogas (methane 50%) in renewable energy.
With this initiative, Lorca leads the energy use of waste beyond the burning of the least self-brand the existing legislation, with an investment of 1.76 billion euros, equivalent to providing electricity to supply between 1,900 and 2,000 housing.
To reach the estimate of 875 kW, HERA Ener · g, company awarded the tender for an initial period of 15 years, provides for the installation of two motor generators Perkins.
The first year will install a 500 kW and the second year another 375 kW.
At full capacity, the Waste Management Centre create (project data) cubic 3,773,900 meters of biogas.
The existence of raw material is ensured by the constant input of waste treatment plant in Lorca.
The forecast is an increase of approximately 70,000 tons per year until 2015.
Currently, Lorca receives waste collected by Limusa and some municipalities of the region, with the volume of waste discharged from 1999 to 2008 of 624,920 tonnes.
Be mentioned that the potential will depend not only on the amount of waste deposited and percent organic matter, but also depends on other conditions such as weather, efficiency of the collection system, impurities in the biogas, and so on.
The characterization of waste landfilled in Barranco Hondo plant reflects a majority composition of mixed MSW and others (42.83%), ie household waste and assimilated, and rejection (41.45%), followed by industrial comparable to RSU (13.89%) and plastics (1.83%).
European legislation obliges all EU Member States must have systems that eliminate and / or recovery of landfill gas emanating from landfills.
In Spain as in many states, one of the systems is by burning torches, thus preventing its escape into the atmosphere.
Methane is a highly polluting gas having a global warming potential 21 times greater than CO2, but the Waste Management Centre of Lorca go beyond current technologies by converting landfill gas into electricity, renewable energy that is transferred to Murcia grid.
