The implementation of the action expected to take advantage to waste heat from cogeneration engines fueled by biogas from waste depuration sludges to heat through a district heating system the Sant. Jordi's swmming pool, located 1.2 km away and improving efficiency in exchange water-air cooling of the WWTP 1 cogeneration engines through a water-water exchange system, multiplying efficiency x 4.
Through the District Heating system waste heat will be used to heat the swmming pool, reducing fuel consumption and therefore CO2 emissions at the same time increase the efficiency of the cogeneration engines cooling system from the WWTP, as we replace the system water-air into water water.
Nowadays fans of fan heaters consume 27KWh to dissipate 375 KW heat, that are required to cooling the cogeneration engines.
With the installation of water-water heat exchangers, the consumption of the pump needed to dissipate the waste heat is 7kWh, so consumption is reduced by 75%.
Replacing gas boilers to swimming pools heating to biomass boilers. To Install 100 kW of photovoltaic panels power to produce electricity to avoid energy consumption from the conventional electricity grid. And to install solar thermal panels, to supporting the swimming pools heating by biomass boilers. 169 flat thermal solar collectors will be installed. The entire project would amortize between 6-8 years.

Son Reus landfill, which is currently closed, generates biogas from landfill. According to recent studies, has a estimated production of 300 m3 / hour gas flow over the next 30 years. The object of this action is taking advantage of generated biogas through internal combustion engines to generate electricity and heat. The energy generated by this flow is 600 kwh and 600 kwh heat. Currently this flow of gas is burned by a torch, which it generates a lot of greenhouse emissions.
