DRY ANAEROBIC DIGESTION OF BIOWASTE FROM MAINTENANCE OF URBAN GREENERY IN NOVEL ROTARY BIOREACTOR
Original language description
Biowaste from the maintenance of urban greenery from Havířov and Karviná cities in the Moravian-Silesian Region, Czech Republic was anaerobically stabilized by a high-solids process in a rotating bioreactor of innovative construction without leachate recirculation. An innovative lab-scale reactor had a square cross-section reaction chamber for easy filling. The total reactor volume was 0.14 m3. The initial inoculation was carried out by adding 40% digestate from an operational high-solids biogas plant processing exclusively the type of urban greenery waste. Four cycles of the batch experiment with a step-up temperature and a shortened residence time were performed. At an average initial batch total solids content of 36.52% the biogas production intensity calculated based on the total reactor volume averaged on 0.732 mN3 m-3 d-1. The average specific production of biogas and methane from the batch, batch solids and batch volatile solids was 0.039 mN3 kg-1, 0.106 mN3 kgTS-1 and 0.161 mN3 kgVS-1 respectively. The biowaste solids itself produced 0.099-0.206 mN3 kgTS-1 of biogas and 0.052-0.118 mN3 kgTS-1 of methane.
