Different types of biomass were gathered to create biomass briquettes that were afterwards tested in a room heating stove. The gathered materials are leftovers from different production processes with the exception of the Common reed that is a widespread wild plant specie. During the collection of these materials a study on the availability of herbaceous resources for production of solid biomass fuels in Latvia was carried out, identifying the availability of these materials in Latvia.
