Client


Tersa
, a Waste-to-Energy plant located in Barcelona.

The Sant Adrià de Besòs Waste-to-Energy Plant (PVE – Planta de Valorización Energética) is a facility that carries out the process of minimising the volume of waste via an incineration process. Energy produced from this incineration is used to generate steam and electricity. The material that these processes create then receive different treatment depending on their characteristics.
