“…9 cal/g) and had a closer calorific value to the TCPS standard of wood charcoal briquettes. Many works showed that the colorific value of fuel briquettes increased as the temperature increased due to volatile matter and moisture content were removed from the briquette while the fixed carbon concentration had increased [8], [9]. The ratio of wastewater sludge and water hyacinth at 1:3 showed the highest compressive strength value (4,545 N).…”

Abstract-This research aimed to study the quality of the fuel briquettes made from sewage sludge mixed with water hyacinth and sewage sludge mixed with sedge. Sewage sludge were mixed with water hyacinth and sedge at the ratios of 1:1, 1:2, 1:3, 2:1 and 3:1 then compressed these mixtures with hydraulic pressure to obtain fuel briquettes and finalized them by analyzing fuel briquettes properties including moisture content, calorific value and compressive strength, then comparing them to the properties of the wood charcoal standard. The result showed that the ratio of wastewater sludge and sedge at 1:3 provided the highest calorific value (3,362.9 cal/g) but still lower than the standard (5,000 cal/g) and the ratio of wastewater sludge and water hyacinth at 1:3 gave the highest compressive strength value (4,545 N). And the moisture content of them was between 4.78% and 7.86%.

“…But biomass has some weaknesses such as scattered resources, low energy density, and inconvenient storage and transportation compared with fossil fuel, seriously limiting its large-scale application. 3 Biomass briquetting technology converts loose biomass such as agricultural and forestry residues into high-density and high-value solid fuels, which improves the characteristics of these residues. [4][5][6] It has become a popular means of using biomass for power generation and residential heating due to the ease of handling both for transportation and for feeders in treatment units, as well as improved conversion and storage possibilities.…”

Biomass such as agricultural and forestry residues is an important resource for energy. Biomass can be converted into densified solid biofuel by briquetting fuel technology to increase the number of applications and enhance its utilization efficiency. In this study, a flat die press machine was designed and studied to realize characteristics of a broad range of feedstock, variable briquetting diameter and length, high briquetting efficiency, easy process control, low processing noise, and low energy consumption. Different experiments were conducted to ensure suitability for large-scale operations while reducing energy consumption, enhancing yield, and lowering product costs. The biomass briquetting fuel system equipment was integrated, and the system could adjust its overall running conditions automatically according to the feed rate, chopping rate, heat supply, output, and feedstock moisture content, allowing for continuous integrated operation. In addition, a biomass hot-blast furnace was used as a drying machine and burned biomass material rather than fossil fuels. This study of biomass briquetting technology supports the large-scale production of densified solid biofuel through the use of biomass resources. V C 2013 American Institute of Physics. [http://dx.

“…It pursuits many manufacturers attempt to tackle this problem with the major reasons for reducing disposal costs and social responsibility [4]. Spent Bleaching Earth (SBE) is solid waste which generated from refining palm oil process [5]. Bleaching earth is used to remove colour, phospholipids, oxidized products, metals and residual gums from the oil.…”

“…In the other aspects, SBE has been used as briquette material. It can be summarized that the SBE waste is feasible for feedstock in briquetting [5]. In addition, valorization of SBE has been performed for using as feedstock in lubricant and biodiesel industries [5], [6].…”
