Assessment of Quality Characteristics of Briquettes Produced From Selected Wood Waste
MetadataShow full item record
The paper presents evaluation of the quality characteristics of briquettes produced from selected wood waste, whose use is part of a sustainable farming policy. The following types of wood waste were used in the study: poplar sawdust, poplar bark, oak shavings and oak bark. In order to crush the poplar and oak bark, a beater shredder was used. Briquettes were made using hydraulic piston briquetting machine. During the briquetting process, the working pressure was 8 MPa. Depending on the type of waste used, the briquettes produced differed in their qualities. Based on the analysis of the obtained results, it was found that the characteristics of produced briquettes were influenced by such factors as the type of raw material, its humidity and fragmentation. The best quality features characterized briquettes made of oak bark and the least advantageous of oak shavings.
