Topinoja - Extension of the AD plant

The facility, actually treating 75.000 ton/year of dewatered sewage sludge, shall be extended to treat additional 35.000 ton/year of Sludge and/ or Source Segregated Organics (in variable amounts from 0 % to 100 % respectively).

The extension includes separate reception and pre-treatment lines for both waste streams, an anaerobic digestion step with two digesters of 4000 m³ and a sanitation step for the total organic suspension produced both in the old and new facility. Special focus will be given to minimize the heat demand of the facility by heat recovery in the sanitation step as well as comprehensive insulation of the tanks, as the produced biogas will be upgraded and liquified to LBG.
