On 11 March 2024, another study visit took place as part of the project ‘Green transformation in practice: demonstration and dissemination of the benefits of biogas production from bio-waste’, implemented by the Institute of Environmental Protection-National Research Institute (IOŚ-PIB) and Vista Analyse. This time, representatives of IOŚ-PIB and the Water and Sewage Management Plant in Tomaszów Mazowiecki visited the Water and Sewage Company in Jarocin.
During the visit, representatives of the Water and Sewage Company in Jarocin and KREVOX, which was responsible for the design of the modernisation of the sewage treatment plant, discussed the entire process from the design to the implementation of the investment. The modernisation included installations for biogas production and the generation of energy (electricity and heat) for the plant’s needs, as well as a phosphorus recovery installation; recovered phosphorus can be used for the production of fertilisers. As a result of these investments, the sewage treatment plant, which has a capacity of over 90,000 person equivalents, can cover its thermal energy needs entirely and, in the case of electricity, approximately 60%.
Modernising of the wastewater treatment plant in Jarocin sets an example for other municipal sewage treatment plants in the country regarding the direction of investments in green transformation.
