ACCIONA designed and built Spain's La Rioja mechanical biological treatment ecopark facilities.
The La Rioja Ecopark complex was built by ACCIONA as a benchmark for Urban Solid Waste Mechanical Biological Treatment facilities. Located in La Rioja, the plant uses the organic elements obtained from USW to produce biogas and compost. The biogas is then converted into energy using cogeneration engines, and the compost is matured and refined to be used as fertiliser.
10,000 tonnes of refuse per year from selective collection
