The company also keeps close cooperation with the experts of the University of Debrecen in form of regular local meetings. The University has gathered information in Békés county, in Budapest and at Kunhegyes about the availability of the raw materials required for the biofuel types and the technical conditions and development plans and directions.

Expected results

* the converted CNG will be used in the inner city centre to contribute to the improvement of emission impacts
