Quality analysis of briquette made of faecal sludge

The purpose of this study is to convert slack waste into charcoal briquettes. The process for making briquettes was carried out by adding polyacrylamide as adhesives. The results showed that the best briquettes were obtained from 16 (sixteen) briquettes, namely the heating value, moisture content, density, and length of combustion were 7436.55 Cal/g; 7.277%; 1.06 gr/cm 3 ; and 613 seconds respectively with the ratio of raw material: adhesive, pressure scale, and drying time were 5:2 105 kg/cm 2 ; and 120 minutes respectively. The characteristics of the calorific value and water content have accordance with the SNI 01-6235-2000 standards, which were ≥ 5000 Cal/g and 7.75%, and the American standard for the density value was 1.0 gr/cm 3 .
