| In Uganda, agro-processing of fruits produces large volumes of agricultural wastes much of which are not utilized but disposed in the landfill. This study explored the possibility of producing biomass briquettes from mango waste (seed covers) that could be used for energy supply in small factories and for domestic cooking. Dried mango seed covers were crushed to particles of size 2 mm and bonded with three different binders; starch, starch-clay soil, and starch-red soil. The best mixing ratios for briquettes were; 4:1 (seed-cover: starch), 9:2:1 (seed cover: starch: clay soil), and 16:4:1 (seed-cover: starch: red soil). The formed briquettes were subjected to several standard methods to verify their suitability as fuels. The briquette properties tested... |

| De acordo com a definição da Convenção de combate à desertificação e mitigação dos efeitos da seca (CCD), realizada em 1994, desertificação é a degradação da terra nas zonas áridas, semiáridas e subúmidas secas. É um processo que resulta de vários fatores, incluindo as variações climáticas e as atividades humana. No caso do Semiárido brasileiro, o mais populoso do mundo, com 23 milhões de habitante, a principal causa desse fenômeno é o desmatamento da Caatinga, seja para ampliar as áreas de plantio e pastagem, seja para fornecer madeira para os fornos das indústrias locais. Esta obra parte do estudo da realidade da região do Baixo-Açu potiguar, uma das áreas com os piores índices de desenvolvimento humano do País, a qual se encontra em franco processo de... |

| This research aimed to evaluate briquettes made from coffee husk, eucalyptus sawdust and maize harvesting residues, and the influence of post compaction interval on some properties of the briquettes. After oven drying of the biomass, the briquettes were produced in a laboratory briquetting machine at 120 ºC and 15 MPa. Bulk density and heating value of the fresh biomass were analyzed. After compaction, influence of time on moisture content, volumetric expansion an bulk density of the briquettes was analyzed. From the results, it was observed that milled coffee husk had the highest mean value of bulk density. There was no statistical difference for higher heating value among the biomass analyzed. The effect of pos compaction interval was significant on... |
