The necessity of using renewable energy sources and limiting the current consumption of fossil fuels was emphasized, among others by changes in production technology. The approach of sustainable development in current energy systems is extremely important, especially in the case of plant-based fuels (biofuels). Poland is a country, where the share of renewable energy sources is still relatively small, and there are ongoing discussions on abandoning coal-based energy and the final shape of energy policy. In addition, the use of biomass from agricultural areas is not too large, although there is a potential for them in the sustainable biomass production plant and this would enable the development of the underdeveloped regions of the country. The most commonly used solid biofuel are briquettes made of vegetable waste, which, with the appropriate production technology, allow to obtain heat with a combustion value similar to that of hard coal. The article presents the preliminary results of laboratory tests of physical properties of fuel briquettes made of wood waste. The research was carried out on three types of wood shavings: pine, oak and hornbeam measuring their density depending on the type of wood and the size of the chip fraction in the pressing process. It has been shown that the size of the raw material fraction has an influence on the obtained density of fuel briquettes. The aim of the research was to determine the suitability of the studied waste wood materials for energy purposes for the production of briquettes. Attention was drawn to the fact that biomass for energy purposes is one of the steps to sustainable energy production and reduction of fossil fuel yield.
