Environmental conservation and respect are present in all business decisions. Firmly following our company policy, which focuses on preserving the environment, it has been deemed right to comprehensively certify our processes.
100% of the sludge generated in 2020 has been appraised, and its journey’s end was as follows: compost (69.06%) and elaboration of artificial soils (30,94%).
The evolution of sludge generation in recent years has been as follows:
2016 > 14.727,36 t
2017 > 17.770,13 t
2018 > 17.017,68 t
2019 > 16.805,93 t
2020 > 19.011,11 t
An average increase of 2% of dry matter has been achieved over the total amount of fresh sludge generated, which has led to a reduction in waste (water present in the sludge) of approximately 38 t. This has resulted in a reduction of CO2 and fuel linked to transport, as well as a logical saving in costs. This reduction has resulted in a reduction of CO2 and fuel linked to transport, as well as a logical saving in costs.
This has been possible thanks to a number of factors:
1º.- WWTP personnel who are in charge of the tasks of drying and dehydrating the sludge enjoying greater involvement and the streamlining of the equipment for the treatment of sludge in the plant.
2º.- Laboratory level tests followed up by on-site tests on the new ranges of state-of-the-art coagulants, mainly of “reticulated” polymers, in the WWTP.
3º.- Monitoring of the measures taken and analysis of the results obtained by the plant’s Operation Technicians.
