The researchers of the Ecotechnology Laboratory are also involved in optimization of the production of biomass-based solid fuels. Such fuels – in the form of pellets or briquettes – can be obtained from the majority biomass feedstocks. In order to achieve it, a proper preparation of the substrate is necessary. Our laboratory is not only able to supply information on the suitability of various materials (including wastes) but is also capable of producing a pilot batchs of such biofuels. We are especially interested in technologies of production of pellets and briquettes derived from waste biomass or containing wastes as additives that improve the calorific value or the structure of such products. We are also equipped to analyze the most important parameters that characterize solid biofuels – their calorific value, heat of combustion, moisture content and ash residue after combustion.
