Description
Spółka Wodna “Łeba" (“Łeba” Water Company) was established in 1981 in the coastal town of Łeba at the initiative of municipal authorities. Its main activities are sewage disposal and treatment. The expansion of our town and a neighbouring municipality necessitates further development of the area''s sanitary sewage system and modernisation of the sewage treatment plant. Therefore the aim of our project is to implement innovation in the processing of sewage sludge, and to reduce the negative environmental impact resulting from the touristy character of Łeba and the resulting high seasonality of sewage inflow.
The key benefits to our company and its environment will be: the recovery of electricity and heat by cogeneration through the production of biogas from sewage sludge by methane fermentation (increased energy efficiency of our company), a reduction in the amount and improved properties of sewage sludge sent for composting, and a reduction of odour nuisance (better waste management). Specifically, the innovations will bring about a reduction of CO2 emissions by 161.25%, a reduction of odour nuisance for 70% of the annual mass of excessive sludge, and a reduction of the emissions of other greenhouse gases (CO, CH4), pollutants and odours, such as H2S and NH3, to the atmosphere.
We will establish cooperation with the Norwegian partner, Aquateam COWI AS, to benefit from knowledge transfer, and the partner’s experience in waste co-digestion. The partner will gain knowledge in the area of seasonal operation of small-scale sewage treatment/microbiogas plants.
