The treatment process of organic waste will reduce 1,000 kilos to 11 kilos of waste ash, as well as reduce emissions and generate electricity and heat

The Minister of Agriculture and Water, Antonio Cerdá, and the mayor of Lorca, Francisco Jodar Lorca presented today at the pilot plant project for energy recovery from different waste materials and by local farmers.

This project is part of the Life Program of the European Union and its results "will be extrapolated" to other EU regions, according to Cerda said.

The owner of Agriculture and Water stressed that this project, "which is a challenge in the investigation" will develop "an innovative system" of collective treatment of waste generated in both the urban and livestock activities, mainly in the pig, which will also help to "generate the energy that these organic materials contained in the form of biogas and biomass," said the counselor.

Agriculture responsible for regional government explained that the Community annually generates more than four million cubic meters of pig slurry and more than 136,800 tonnes of other waste from sewage sludge, pig slaughterhouses, Natural bodies of pigs remains pruning and timber gardens and useless.

This treatment is expected to reduce the volume of waste to 1.1 percent, which means that for every 1,000 kilos of waste receive 11 kilos of ash that can be reused in cement or asphalt road.

All this, "producing more energy than is consumed in the process," noted Cerdá.

Project Benefits

The objectives of this plant "are many and positive," said the adviser, who emphasized that in addition to "recover waste generated every day, earning power" is reduced between 77 and 89 percent carbon emissions compared with classical systems of incineration and generates both electric and heat energy.

According to forecasts, with the waste produced in the municipality of Lorca could get 4,600 tons of "optimal mix", which would be treated after production of electricity for 2,700 homes, thermal energy production of almost 3,500 megawatts, free more than three million liters of water, and reducing the initial volume of organic matter and 50 tons of ash.

Initially, this pilot treatment system has the capacity to manage a total of 36,400 kilos of waste and by-products annually, which represents 0.002 percent of the total mass estimated to be generated annually in the town of Lorca.

The director hoped that the results obtained from the project serve as a model for other research groups "in the study of renewable energy production from anaerobic digestion of organic residues and biomass burning.
