“…al, 2009;Emerhi et al, 2011;Mungale et al, 2016). The extensive diversity uses of briquettes range from household to industrial and for high-pressure briquette, the sawdust, rice husk and woody residues are the most excellent materials (Achebe et al, 2018;Abdulrasheed et al, 2015) for the reason that they have a high percentage of lignin. However, the majority of parched agricultural residues can be utilized if grounded into an uncouth powder (Oladeji, 2012;Onuegbu et al, 2012).…”

“…The significance of sawdust along with rice husk at the same time as a source of fuel cannot be overstated as it is willingly available and economical (Arevalo et al, 2018).In Nigeria, it is most frequently discarded or scalded off at sawmill sites, hence lots of energy is being wasted and unrestrained heat generated (Achebe et al, 2018;Babajide et al, 2018). Sawdust has been utilized over the years in support of the production of heat and power in gasification of plants and for household cooking (Shekhar, 2011;Shyamalee et al, 2015).…”

In this study, investigations were carried out on the energy evaluation, performance analysis and optimization of briquettes produced from biomass wastes (rice-husk and sawdust) and their composites using starch and clay as binders. The proximate compositions of the briquettes were determined following ASTM analytical methods. The moisture content of rice husk and sawdust before briquettes was 20wt.% and 15wt.% respectively. The briquettes produced from bio-waste material of homogeneous particle sizes of 0.5mm and two binders of a percentage of 90:10 which were sun-dried, prepared and moisturized, were reduced to 5wt.% and compressed for the production of briquettes. The energy evaluation of the briquettes was performed using an oxygen bomb calorimeter and the performance test of the briquettes was carried out. Design Expert Central Composite Design Tool was used in the design and Response surface methodology was used to optimize the energy values of rice-husk/sawdust composite briquettes with clay and starch as binders, after which composite briquette made of mahogany sawdust/rice-husk were produced using the optimum condition values of 15% binder starch, 28% rice-husk and 9Mpa compaction pressure. The results showed that composite briquettes of mahogany sawdust and rice-husk produced with starch had a maximum energy value of 5.69kcal/g, while those made with clay had a minimum energy value of 3.35kcal/g. However, the experimental result was less than the predicted optimum value of 2%. This shows that composite briquette made from mahogany sawdust/rice-husk has better energy efficiency than other briquettes considered and it has been observed that starch is a better bonding material than clay. Briquetting technology has great potential to transform waste biomass in affordable, effective and environmentally safe, high-quality solid fuel for households and industry use.

Canewood and palm kernel fibre (PKF) have successfully been used as filler material for producing ceiling boards, with recycled low-density polyethylene (LDPE) as the binder. This work covered three aspects which are the optimization of process and production parameters, chemical, and thermal analysis of the utilized filler material. The production parameters considered are the percentage composition of both the binder and filler material while the process parameters studied are the press temperature, pressure and time. These parameters were optimized over both physical and thermal properties of the developed ceiling board which are thermal resistivity, water absorption and thickness swell. Thermal results for both the cane wood and PKF proved to be thermally stable up to temperatures as high as 325 and 310°C, respectively. The optimized ceiling board showed a thermal resistivity, water absorption and thickness swell of 16.192 W/M.K, 4.669 and 6.594% respectively, for a production and process parameters of 15% cane wood, 10% PKF, 75% LDPE, 6 min press time, 7 bar pressure and 198°C press temperature. The produced ceiling board showed a specific heat capacity, thermal energy and heat flux of 769.23 Jkg−1K−1, 60 W and 23.07 kWm−1 respectively. The findings imply that the LDPE filler materials are appropriate for use in ceiling board applications.

“…The fixed carbon of a fuel is the percentage of carbon available for combustion (Achebe et al, 2018). The highest percentage of fixed carbon content of sawdust briquette might be a good bondage and uniformity of particles size helpful to increase the fixed carbon content and heating value of producing briquette.…”

Renewable energy is one way to deal with the scarcity of fossil energy. Biobriquette is an alternative energy that can be used as a substitute for fuel. This research aims to determine the characteristics of each variation of biobriquettes, namely moisture content, ash content, volatile matter content, bound carbon content, calorific value, and combustion test. The raw material is sawdust of Sungkai wood (Peronema canescens Jack) with carbonization method at 300 o C for 1 hour. This study used an experimental method by varying the sawdust weight of 8.7 g, 17.4 g, 26.1 g, 34.8 g with a ratio of 2:1 for each raw material and adhesive used lubricant oil. In addition, the drying temperature of the briquettes is also varied by 80 o C (A) and 100 o C (B). Biobriquettes 4B had the best moisture content and ash content with the lowest levels of 5.98% and 1.54 %, respectively. The levels of volatile matter and fixed carbon levels are closest to Energy and Mineral Ministry Regulation Number 47 of 2006 (PERMEN ESDM) namely 4A briquettes of 59.44% and 1B briquettes with a content of 31.57%. Almost all samples met the standard for calculating the calorific value of Energy and Mineral Ministry Regulation Number 47 of 2006 (minimum 4400 cal/gr) with a the result of 4512-4850 cal/g. The ignition time of all samples was in the range of 9.67-17.9 seconds, it is faster than the ignition time of coal in the range of 286 seconds. The fastest burning time was sample 3B with a time of 19.83 minutes and the longest was sample 4A with a time of 38.95 minutes. The briquettes that had the best performance in boiling 100 ml of water were 4B briquettes with a burning temperature of 462.3 o C, a burning rate of 0.4501 and a boiling time of 2.48 minutes.
