Abstract: | The reuse of waste and by-products from industrial activity is a real necessity for the sustainability of activities in this sector. The aim of this work was to evaluate the quality of briquettes produced from the reuse of charcoal fines and lignin from the Kraft process, in different formulations. The immediate chemistry, bulk density, calorific value and compressive strength of the briquettes were determined. Based on the results obtained, we found an inversely proportional behavior between fixed carbon and volatile materials, where the variation in Kraft lignin content in the briquettes was the determining factor for this behavior. It was also observed that the Kraft lignin content had no influence on the mechanical strength, bulk density or calorific value of the briquettes. In general, the briquettes produced from charcoal grindings and Kraft lignin showed interesting characteristics for bioenergy use, but qualitative and quantitative studies of combustion gases are recommended when the aim is to use them for cooking food. |
