The Possibility of Using Composted Biowaste with the Addition of Biochar for Energy Purposes

Original language description

After the biowaste composting process, not only is wholesome compost or a substance for increasing soil fertility, but also non-composted waste. Non-composted waste is returned to the composting process or is utilized in the recovery process, e.g. in degraded land reclamation. The purpose of the study was to determine the energy potential of composted biowaste. The research was carried out in Composting Plant in Brno on biowaste samples from households supplemented with biochar in the share of 1.5%, 3%, 5% and without the addition of biochar (the control). The analyses included biowaste and the 3 weeks of intensive phase of the composing process. Sampling for analyzes was performed every week for the first three weeks of the process. The samples were divided into those from which it was possible to obtain compost (with granulation below 20 mm) and the process residue that did not meet the requirements for composts (fraction with a particle size of over 20 mm, containing impurities). The study included: moisture content, ash content, carbon content as well as the heat of combustion and calorific value. The research results revealed that the heat of combustion and the calorific value for samples with grains below 20 mm decreased very quickly during the intensive phase of the composting process. Samples with a particle size above 20 mm can be a source of energy for the power industry, due to the heat of combustion above 9 MJ.kgMINUS SIGN 1 (and with the addition of biochar above 10 MJ.kgMINUS SIGN 1), but after prior drying of the waste.
