“…From the plot, it could be observed that as the binder proportion increases, the burning rate also increases, which indicates that clay and waste paper binder has significant effects on burning rate. This is contrary to the findings of Hassan et al, (2017) where they reported that a carbonized material blended with waste paper increases the burning rate and thermal conductivity of the briquettes.…”

Demand for green environments has stimulated research on the migration from conventional to renewable energy sources. In the case of combustible energy for domestic applications, briquettes produced from biomass have proven to be a good replacement for wood fuel. In this study, investigation on the performance analysis and optimization of mix ratio of briquettes produced from sugarcane bagasse using composite binders (waste paper and clay) was carried out. Box-Behnken Design feature of the Design Expert software was employed for the optimization of the briquettes mix ratio. Briquettes were produced from sugarcane bagasse based on the optimum conditions of 9.12% clay, 12.57% waste paper, 78.31% proportion of sugarcane bagasse and 5 KN compaction pressure. The produced briquette was found to have a compressive strength of 6.4715 MPa and 0.857 g/min burning rate. The results of the study shows that the experimental values were close to the predicted values with a percentage error of 3.11% for compressive strength and1.79% for burning rate which confirms the validity and adequacy of the predicted models.

“…The burning rate (vcomb) of the samples ranged from 188 to 288 g/h ( Figure 4b); that of charcoal is 333 g/h (Figure 4b). Our findings were almost the same as those found by Hassan et al (2017) for briquettes produced from carbonized Martynia annua woody shells and wood charcoal: 3.68 g/min to 4.76 g/min (equivalent with 220 g/h to 285 g/h). The PG1 and PG2 briquettes sprayed higher amounts of water (Figure 4a).…”

“…The energy content of our briquettes can be evaluated by exploiting the temperature variation curves of the heated water. The briquette samples BB1, PG2 and PG1 had approximately the same rate of combustion (0.5kg) and ensured the boiling of water (100°C) during 40-80 minutes ( Figure 5); this time was slightly higher than that found by Hassan et al (2017) from 12 to 15 minutes, during the combustion of 225 g to 275 g of briquettes. Their curves representing the temperature variation evolved linearly.…”

Towards the Promotion of Fuel Briquettes Using Municipal Solid Waste and Residual Biomass in Burundi

The issue of domestic energy is still a major concern in developing countries. A sound knowledge of fuel characteristics is a major asset for their acceptability and their distribution. Samples of briquettes made partially with Municipal Solid Waste (MSW) were collected in several companies with unknown characterization. This study intended first to characterize them for physical and chemical properties. Subsequently, energy content of the briquettes and the energy price are presented and compared to those of charcoal and peat, which is typically used by the local population as fuel. To classify the different briquettes according to their quality in terms of rate as well as their level in fire resistance, cooking tests and heating curves have been made. The calorific value of the studied briquettes varied from 12.3 to 18.6 MJ/kg compared to 32.5 MJ/kg for charcoal and 14.7 MJ/kg for peat. Consequently, their value as viable substitutes for charcoal or peat is apparent. However, some samples burn very quickly and do not provide prolonged heating while other samples have a slow rate of combustion and release little energy. Finally, the briquettes using MSW have a low price between $0.16 and $0.19/kg compared to the price of $0.53/kg for charcoal and $0.20/kg for peat. The promotion of these briquettes as a valuable substitution fuel is proved and contribute to sustainable development by reusing MSW and avoiding deforestation.

“…Low volatile matter makes the briquettes to burn slowly and the opposite is true (Ige et al, 2020). This is similar to the findings by Hassan et al (2017), the improvement of fuel ignition time and the burning rate with the increase in binder ratio is due to a higher volatile content (Hassan et al, 2017).…”

Fabrication of Sawdust Briquettes Using Local Banana Pulp as a Binder

et al. 2022

Sawdust is generated in large quantities in sawmills in Manicaland province in Zimbabwe, posing an environmental threat if incinerated or left to accumulate. This presents an opportunity for valorising the waste into briquettes. To make the briquettes cost effective, a cheap and locally available binder is needed. Hence, the use of banana waste pulp (green banana, ripe banana, pseudo-stem pith and fruit-bunch-stem) as a sawdust briquettes binder was investigated in this study. The quality of fabricated briquettes was evaluated based on relative density, shatter index, ignition time, burning rate, and time taken to boil a constant amount of water. The briquettes showed improved qualities with the increase in binder ratios. The sawdust-binder ratio of 1:4 showed the best briquettes qualities. Factor rating method was done in order to obtain the best scored (scale 0-100) briquettes reflecting weightier factors (scale 0-1). The weightiest factors were time taken to boil water (0.25) and shatter index (0.25), with three other factors weighing 0.5. The best five binder formulations in their order were; banana-pseudo stem-pith (pith) and ripe banana (RB) in the ratio of 3:1 respectively (score weight of 68.75), fruit-bunch-stem, banana-pseudo-stem-pith (pith), green banana (GB) and ripe banana (RB) in the ratio of 2:2:1:1 respectively (score weight of 68.3), banana-pseudo-stem-pith (pith), ripe banana (RB) and green banana (GB) 2:1:1 respectively (score weight of 66.95), banana-pseudo-stem-pith, ripe banana and green banana in the ratios of 2,5:1,5:1 respectively (score weight of 66.05) and banana-pseudo-stem-pith and ripe banana in the ratios of 1:1 (score weight 65.55).
