“…This value is within the acceptable limit of 5-4 wt% for solid biomass [27][28]. It is also in line with 3.4% -4.9% from non-woody biomass by Babajide et al [24], and lower than the value from Jirijor et al [19] which recorded 4.53% -10.12% for nonwoody biomass. High ash content is detrimental to combustion and leads to fire management problems, such as regularly removing ash from the stove.…”

“…The results of testing of the equipment revealed that the highest binder concentration ratios of 30% and 40% produced the best result. Yirijor et al [19] assessed the physical and mechanical properties of briquettes produced from dry coconut husk tagged "CNH" and cocoa pod tagged "CCP" Ghana. The agro-waste was gathered, carbonised at 450 o C carbonizing temperature.…”

This study investigated the quality of biomass fuel briquettes; a Refuse Derived Fuel (RDF) made from bio-wastes generated from a local farm produce market in Nekede, Owerri, Nigeria, known as Umuokomoche daily market. The wastes were mainly waste groceries; vegetable stems, leaves, fruits, plantain peels and stems, yam and potato peels, corn hob and all sorts of discarded food / agro materials which constitute over 70% of the total Municipal Solid Wastes (MSW) generated by the community. The study involved the design, fabrication and installation of a piston-type, hydraulic powered pedal operated Biomass Briquetting Machine. The briquettes produced were tested, in order to ascertain their quality as Refuse Derived Fuels (RDF). The biomass wastes generated were initially gathered, sun dried and carbonized through pyrolysis in a kiln. The biochar was then crushed and mixed with a 20% starch bond and finally fed to the machine as feedstock. The products (briquettes) recorded satisfactory combustion outcomes when tested. The preliminary results showed a calorific value of 4900Kcal/Kg which is adequate as a reliable and alternative energy source for domestic and industrial applications. Other parameters tested are; fixed carbon at 32%, Volatile matter at 44%, Moisture at 5% and are Ash content at 5.02%. A bulk density of 580 kg/m3 and a Compressive ratio of 1:2.5 were also recorded. Both results confirm the handling ability and ease of transportation of the briquettes. Therefore the briquettes are of good quality and reliable as an alternative energy source for domestic and industrial applications.

“…Sample A generated a better calorific value at 18704.1 Kj/Kg while sample B had a calorific value of 18901.3 Kj/Kg. Although both results are a bit lower than the reported value for wood fuels in Iyer et al [14], but they are far better than minimum heating value for briquette production [19,20,21]. Sample B has a higher calorific value when compared to sample A as well as a better combustion characteristics.…”

The combustion characteristics of two carbonized biomass briquettes fuels samples (sample A and B) from two bio-wastes have been presented. Sample A is comprised of Agro-waste (residues) mainly rice husk, groundnut shell, corn cob, bagasse, rice straw, coconut coir, branches, wheat straw, maize husk, grass from the field, cassava stem while Sample B comprised of decaying domestic wastes material from wastes disposal/collection points mainly garbage, vegetables/fruits, protein, groundnut shell, maize cob, waste papers, all sorts of discarded foods etc. Analysis of briquettes fuels samples in terms of proximate analysis, ultimate analysis and calorific values were necessary to determine suitability of such material as reliable and sustainable energy sources. These parameters analyzed are unique fundamental code that characterizes and determines the properties, quality, potential applications and environmental problems related to any fuel. The result of the analysis placed sample B above sample A in terms of heating value. The proximate analysis indicated that the sample B had a better ignition characteristic at 77% volatile matter against 44% of sample A. Also, sample B have better heating value with fixed carbon 32% against 21% of sample A. This was also confirmed by ultimate analysis where sample B recorded a higher value of percentage Carbon and percentage Oxygen at 47.04% and 41.6% respectively. The bulk densities were in the range of 499kg/m2 to 502kg/m2 which is very good in terms of handling and transportation of the fuels. Moreso, calorific value of both samples were appreciably high at 18704 KJ/Kg for sample A and 18901.3 Kj/Kg by sample B. The ratio FC:VM for sample A is 0.477 which is higher than that of sample B, indicating that sample A will have a better yield and formation of biochar. Therefore the carbonised biomass briquettes are of good quality and exhibited good combustion properties as an alternative energy feedstock for domestic and industrial applications. It is a better source of energy for cooking, replacing fuel wood (firewood) and it is eco friendly.

“…Combustion refers to the conversion of biomass to heat and power by directly burning it, as occurs in boilers. Gasification is the process of converting solid biomass with a limited quantity of air into producer gas, while pyrolysis is the thermal decomposition of biomass in the absence of oxygen" [1][2].…”

Pyrolysis is a thermo-chemical process of biomass conversion to a carbon neutral or better fuels and materials from biomass. It is a thermal decomposition of organic material in a controlled (insufficient) oxygen at a high temperature thereby producing solid (biochar), liquid (oil) and gaseous products. Biochar produced during this process is a very valuable material that can be utilized as soil additive and in carbon sequestration, where the carbon can be stored (locked) in the soil. The result is improved soil structure, pH, water and nutrient retention and the mitigation of climate change. Biochar can also be utilized as biofuel in energy generation directly or converted to biomass briquettes thereby, improving its energy and economic value. Therefore, the present study, involved the production of biochar from an improvised 100 litres volume pilot carbonization kiln and experimentally studied the biochar yield. The result showed a yield of 2505g at average charring ratio of 33.9 % from 7396g of composite wastes, comprising of 1844g of mixture of Maize cob and coconut husk, 1030g of mixed vegetable stem and discarded fruits (sundried watermelon and fruits, 3321g of peeled yam, cassava peels, potatoes peels and discarded food materials, and 1201g of plantain bunches and peels. This results is an indication of good performance outcome of the carbonization kiln in biochar production for soil nutrient improvement and (or) for energy supply applications as refuse derived fuels (RDF).
