Agricultural residue biochar bio-composite briquettes as sustainable domestic energy sources
In this study bio-composite briquettes were developed from rice husks, coffee husks and groundnut shells. The briquettes were developed under low pressure (≤ 7 MPa) after carbonization and application of starch binder. Determined calorific values and physical properties, mechanical strength and integrity of the developed briquettes. Results for drop strength for the developed composite briquettes were all above 86 %, indicating satisfactory characteristics. Bio-composite briquettes developed using coffee and rice husks bio-chars took less time to boil water compared to all the
Recycling of Cashew Nut Shells Waste in Asphalt Concrete and Briquettes
The global cashew nut production worldwide has reached about 4 million tons in 2017. West Africa, with about one third of cashew raw nuts worldwide production, is the largest cashew nut production region. This cashew production generates large quantities of cashew nut shells (CNS) waste that must be disposed. This study aims to valorize CNS ashes in asphalt mixtures. Different proportions of ashes were added as partial replacements to the very fine sand element in the asphalt concrete. The physico-mechanical properties of the mixtures were tested using the
Charcoal briquettes from agricultural waste as alternative fuel
Bio charcoal briquettes are one of the fuels that come from biomass. This study aims to know the characteristics of bio charcoal briquettes from maize cob with compaction pressured (22.426 kg/cm2 and 44.80 kg/cm2) and particle size variation (40, 50, and 60) mesh. Analysis the characteristics of briquettes includes: density, moisture content, ash content, volatile matter, fixed carbon, heating value, ignition time and flame rate. The process of making briquettes was making charcoal from
