1. Fighting climate change

 Objective met in 2017 (in regard to the objective for 2021)

 

In the wastewater treatment plant of Mataró (Barcelona), biogas that is produced during the water treatment process is transformed into electrical and thermal energy.

The electricity energy that is generated is used for the operation of the plant's machinery, and the thermal energy enables the right temperature to be maintained for the micro-organisms to degrade the organic material.

The four microturbines installed for the transformation of biogas generate 1,934 MWh per year, a figure that covers 37% of the plant's consumption and represents a saving in the purchasing of electricity of 72,000 euros.

 

"The fight against climate change is one of the greatest challenges faced by current society; at SUEZ in Spain, we are clearly committed to this. We work in three core areas to reduce our carbon footprint: purchasing of energy with a certificate of origin, an energy efficiency plan, and generation of renewable energy."
Javier Presas, Energy Manager
