The aim of the project was to utilise the potential energy of the treated wastewater between the sewage water reservoir and the outflow pit by installing a micro scale hydro turbine between them. The treated wastewater used to flow into the Danube while its potential energy was unused. The machine itself is really simple, consisting of a vacuum start-up system, a nonadjustable guide vane row, a simple four propelled impeller and an induction motor as a generator.

Green Fund is part of the MOL Group’s 2020 SD Action Plan, which shows that sustainable development plays an important role in our future.

The goal is to increase the number of green-focused solutions with significant environmental benefits. The Green Fund has an annual budget of 1 million USD, distributed among the winners of an internal competition. Since 2016, more than 20 projects have been implemented.

Even though the geographical location of the refinery was a crucial factor of the realization of this project, the approach that led to its success can be applied MOL Group wide.
