A new project will use wastewater to reduce water consumption at the Mataró plant

The aim is to save 50% in the consumption of drinking water

Mataró, April 1, 2024.

Valoriza Servicios Medioambientales is participating in a project to take advantage of the wastewater from the Mataró Wastewater Treatment Plant (WWTP) and use it in the processes of the Maresme Integrated Waste Valorization Center, with the aim of saving 50% in the consumption of drinking water.

In the first phase, the aim is to use the wastewater in the air treatment, biomethanization and ultrafiltered water production processes of the mechanical-biological treatment plant. This is responsible for the stabilization of organic matter and the recovery of recyclable materials from the residual fraction, the gray container.

These three processes have an annual consumption of 20,000 m3 of water and this proposal will reduce the consumption of drinking water by 20%.

On the other hand, the intention is to use the wastewater in the Center's energy recovery plant, estimating a reduction in water consumption of 30,000 m3 per year, i.e., a reduction of an additional 30%.

The Integrated Waste Recovery Center, which belongs to the Maresme Waste Consortium and is managed in a joint venture by Valoriza, treats more than 190,000 tons per year of residual waste from Maresme and Vallès Oriental, prioritizing the recovery of materials from all recyclable products, including organic matter - in 2023 it recovered 20,300 tons of materials - and then optimizing energy recovery.

It also treats bulky waste - 14,700 tons in 2023 - and transfers the waste from the selective collection of the packaging, organic and glass fractions collected in the 28 consortium municipalities in the region.
