This new infrastructure will guarantee treatment of all organic matter from selective collection, which began on November 1, 2017 in the municipality of Madrid. The selective collection service will be implemented in all districts of the city from December 1, with the exception of the Central district, where selective collection will commence in 2020. The initiative will also contribute to achieving the EU 50% recycling target for municipal waste as well as the target of reducing landfilling to 35% set out in the Spanish State Waste Management Plan.
Through the implementation of a versatile, modular and highly automated process, the new Valdemingómez plant will be capable of composting 102,490 tonnes of organic waste per annum, thus closing the organic matter management cycle.
The technological solution chosen for the construction of this new plant will ensure that the quality of the end product obtained in the recycling process (compost) is sufficient to enable its use as a soil improver or fertiliser. Segregated organic matter recovery also prevents greenhouse gas emissions and foul odours, whilst facilitating improved selective collection of other recyclable wastes.
Separation of organic waste
Organic waste is made up of leftovers from: fruit, vegetables, meat, fish and seafood, nuts, tea and coffee dregs, eggshells, other foods, sawdust, used kitchen roll and paper napkins, paper and cardboard soiled by oil or food, as well as the remains of plants, leaves and flowers.
In order to recycle organic waste, it must be separated from the unrecyclable rest fraction (the refuse deposited in the container with the orange lid in Madrid) and deposited in the grey containers with the brown top deployed by the City Council in the streets, and the bins of the same colour issued to apartment blocks and communities of property owners. Collection from all these containers is carried out on a daily basis (including public holidays) by ECO-class refuse collection and compactor trucks, and the organic waste is not mixed with other fractions.
