Many cities face a long-term surplus of grass cuttings. Its management is usually financially demanding once many of the up to date technologies require high acquisition as well as variable costs. It was verified in a commercial scale if the newly proposed concept of anaerobic fermentation followed by continuous pyrolysis is technically and economically feasible to manage macerated cutting of urban green in a commercial scale. Design of the concept is thoroughly described, documented in figures, and biochemically analyzed in detail. Assessment of the concept shows that subsequent pyrolysis of the anaerobically fermented residue allows among biogas to produce also high-quality charcoal. It was proved that the proposed solution improves the overall economy. In addition, it may be assumed that this applied research is consistent with previous theoretical assumptions stating that any kind of aerobic or anaerobic fermentation increases the heating value of the charcoal obtained.
