Abstract

This study aimed at the synthesis and characterization of briquette from Pinus patula saw dust using different binders. The effects of particle size and type of binder on the fuel qualities of the briquette were investigated. The bulk density of biomass causes handling, storage, and transportation problems that limit its large application. Densification of biomass into briquettes can solve these problems. The experimental results indicate that briquette produced from waste paper, fruit waste, cow dung, and starch flour binders has higher calorific value, higher fixed carbon, and lower ash content. Whereas, molasses and wood ash binders decreased the calorific value and fixed carbon and increased the ash content of the briquette. As a result, a maximum calorific value of 6596 cal/g, fixed carbon content of 62.6%, and ash content of 3.66% are obtained using waste paper.  The calorific value of 6232 cal/g, fixed carbon of 48.74%, and ash content of 3.33% was obtained using fruit waste while the calorific value of 6194 cal/g, fixed carbon content of 59.94 %, and ash content of 5.35% was observed when cow dung is used. When starch flour is used, a calorific value of 6170 cal/g, fixed carbon content of 54.63%, and ash content of 2.63 was obtained. Therefore, waste paper, fruit waste, cow dung, and starch flour are promising binders that improve the fuel qualities of biomass briquettes.

Abstract

This study explored the potential of Cupressus lusitanica Sawdust for the production of pellets from carbonized sawdust using different natural binding agents (molasses, starch flour, fruit waste, and waste paper). The impacts of particle size and the type of binding agent used on the fuel qualities of pellets were investigated. The experimental results highlight that pellets produced from waste paper and starch flour binders exhibit high calorific values, high fixed carbon, and low moisture content. In contrast, molasses and fruit waste binders lower the fixed carbon and calorific value of pellets. As a result, the maximum calorific values were obtained using starch flour and waste paper, with respective values of 7052 and 7046 (cal/g). Maximum fixed carbon contents were 79.5% and 76.67% for waste paper and starch flour bonded pellets. Fruit waste and molasses binders result in lower calorific values, with respective values of 4831 cal/g and 5034 cal/g respectively. Pellets produced from fruit waste and waste paper showed lower ash contents of 1.53% and 1.67% respectively, indicating their environmental advantages. Therefore, starch flour, waste paper, molasses, and fruit waste are effective binders for biomass pellet production with improved quality.
