Combustion characteristics of rice husk and coconut shell briquettes have been investigated with a view establishing its suitability as an energy source. The were collected carbonized in furnace charcoal (RHC) (CSC). These further down sized sieved to 2.5 mm particle size. RHC CSC mixed proportions 50:45, 60:35, 70:25, 80:15, 90:5% by weight respectively, 5% cassava starch used binder for all t...

The increased demand for infrastructure due to global population growth has resulted in the depletion of natural aggregate sources and escalation cost building materials. There is also problem environmental pollution as a result wastes generated from agricultural activities. This led various studies aimed at investigating use waste materials substitutes aggregates concrete. In this research, sa...

The adsorption of the fungicide Carbendazim (CBZ) on granular activated carbon (GAC) coconut shell was investigated through batch tests in deionized water. most favorable conditions for CBZ were examined variation mass GAC, temperature, and contact time. Response Surface Methodology (RSM) applied, seeking best condition to optimize future tests. A thermodynamic analysis carried out using Van't ...

The manufacture and characterization of coconut shell briquettes using tapioca as adhesive were conducted. sample is created different flour concentrations: 1%, 3%, 5%, 7%, 9%. All briquette samples dried for 30, 60, 90 minutes. Coconut characterized scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX), Fourier transforms infrared (FTIR), compression tests, burn rate test...
