Vilanova de Arousa (Pontevedra) to have new biowaste treatment plant by end of year

Vilanova de Arousa (Pontevedra) contará para finales de año con una nueva planta de biorresiduos

PreZero España, together with other local companies (Arias Infraestruturas, SA – Petrolam Infraestruturas, SL – Prace, Servicios y Obras, SA), has been awarded the contract for the construction and commissioning of a biowaste treatment plant in the municipality of Vilanova de Arousa (Pontevedra). The contract is valued at €15,109,215 euros (including VAT). The facility, which is expected to enter into operation at the end of the year, will serve 26 municipalities and will have the capacity to treat up to 15,000 tonnes of organic matter per year, and another 7,000 tons of pruning and wood waste.

This facility will be integrated into the infrastructure network designed by the Galician Regional Government to ensure that most of the municipalities served by Sogama, the publicly-owned company that acted as the contracting authority in this tender procedure, can recover organic matter by converting it into compost.

According to current regulations, separate collection of organic matter must be implemented through the brown container by December 31, 2023. Although this is an area of municipal competence, the Regional Government will make available to local authorities the necessary means to achieve due compliance with current waste legislation, thus making decisive progress towards compliance with European recycling targets for the year 2025.

Characteristics

The facility, which is expected to start operating at the end of the year, will serve 26 municipalities with a totl population of 326,846 and will have the capacity to treat up to 15,000 tons/year of organic material and another 7,000 tons of pruning and wood waste. It is also estimated that it will produce around 6,000 tons/annum of compost, which will be used in the agricultural sector as a natural fertiliser to replace artificial fertilisers.

The plant will integrate the entire process of composting the waste received. This process will be carried out in enclosed buildings and will include all composting stages – pretreatment, fermentation, maturation and storage – as well as associated air and water treatments. The best available technologies will be implemented at all times for the composting process as well as for odor and noise control. The industrial processes will be powered by renewable energy, mainly provided by solar panels.

The Vilanova plant, along with those of Cervo (Lugo), Verín (Ourense) and Cerceda (A Coruña) -the latter already in operation-, will be supported by 13 transfer plants equipped with hoppers specifically designed for the transfer of organic matter. A total of 17 facilities will cover practically the entire Galician territory, enabling municipalities to have a biowaste or transfer plant within a radius of 50 km.

Due to its positive impact on environmental protection and, consequently, on quality of life, this action is co-funded by the ERDF as part of the European Union’s response to the COVID-19 pandemic.
