Effects of binders on the mechanical and physical properties of briquettes

Abstract

In this study, carbonized briquettes were developed from coffee and rice husks as agriculture wastes using cassava starch and banana pulp as organic binders and clay as an inorganic binder. The bio-char after carbonization of wastes were weighed and for every 1000g of char were mixed with the different binder ratios i.e. 35, 45, 55, and 65g cassava starch, 500, 1000, 1500, and 2000g banana pulp and 150, 250, 350 and 450g clay binder ratios. The low pressure technique was used to develop carbonized briquettes. The physical properties of the developed briquettes were determined using Thermo-gravimetric analysis. Density and the drop test method were employed to ascertain the mechanical and storage integrity of the developed briquettes.
