“…Ash content of T1, T2, T3, and T4 45.93%, 31.69%, 36.83%, and 37.73%, respectively. Ash content of T2 is the lowest than others, but this result is different from the study conducted by Bot et al, (2021), who reported that the ash content in coconut shells was 10.02%, Note: 100% tobacco stem (T1), 80% of tobacco stem + 20% of coconut shell (T2), 80% of tobacco stem + 20% rice husk (T3), 33.33% of tobacco stems + 33.33% of rice husk + 33.33% coconut shell (T4). Means followed by different letters in the same column are significantly different based on Duncan's 5% test.…”

Tobacco stems contain 56.10% cellulose content, 15.11% lignin, 22.44% hemicellulose, and 44.61% total organic carbon, which can be used as a source of energy or fuel. This study aimed to utilize tobacco stems in a briquette form as alternative energy. The materials used in this study were tobacco stem waste, rice husk, wood charcoal, and coconut shell. The treatments used in this study consisted of T1 (100% of tobacco stems), T2 (80% of tobacco stem + 20% of coconut shell), T3 (80% of tobacco stem + 20% rice husk), and T4 (33.33% of tobacco stems + 33.33% of rice husk + 33.33% coconut shell). The fastest combustion rate was found at T3, 0.12 gram/sec, while T1 and T2 had the same combustion rate. T4, a mixture of various materials, had no significant difference compared to T1, T2, and T3. The highest calorific value of tobacco stem briquettes was in T4 (4127 Kcal/kg), and the lowest was in T1 (2343 Kcal/kg). The combustion rate of these tobacco stem briquettes was longer than that of charcoal briquettes, whose average burning rate is 0.234 grams/second. Overall, this study provides an overview of the best combination to create briquettes from agricultural waste.

“…Prior to producing briquettes, the dried banana peels, pineapple peels and water hyacinth were carbonized using slow pyrolysis at temperatures of 400 °C [42,43]. The process was carried out using a locally fabricated carbonizer.…”

“…High compressive values are an indicator of high crush resistance, an aspect that is important during the handling and transportation of the briquettes. Compressive strength was determined by means of a universal testing machine (UTM-Tinius Olsen H50KT, USA), connected to a computer to enable real-time data logging, following a testing procedure according to [43,44]. The briquettes were placed in between the two-machine sample holding plates and a uniform load (50 kN) was applied perpendicularly to the axis of the tested briquette at a rate of 1 mm/s until failure.…”

“…The moisture content was lower in carbonized briquettes than in uncarbonized briquettes, because the hydrophilic hydroxyl group is destructed [47]. The carbonization process helps in reducing absorption of moisture, which is a necessary aspect for increased shelf life and storage of briquettes, preventing rotting and decomposition [42,43]. High moisture content in briquettes results in swelling and disintegration [47], and it interferes with thermo-chemical conversion processes.…”

Background: Uganda's energy needs are heavily reliant on biomass sources. This dependency of Uganda's burgeoning population on biomass for household and commercial purposes is posing pressure on natural resources such as forests. This study was carried out to investigate the utilization of some of the country's highly produced agricultural waste for the creation of biofuels.Methods: Pineapple peels, banana peels and water hyacinth were utilized for generation of both carbonized and uncarbonized briquettes. Physical properties and calorific values for the developed briquettes were determined through thermogravimetric analysis and using a bomb calorimeter.Results and conclusion: Pineapple peel carbonized briquettes had the highest calorific value (25.08 MJ/kg) followed by a composite of banana peels and pineapple peels (22.77 MJ/kg). The moisture content for briquettes ranged between 3.9 to 18.65%. Uncarbonized briquettes had higher volatile matter (ranging between 62.83 and 75.1%) than carbonized briquettes (ranging between 22.01 and 24.74%). Uncarbonized briquettes had shorter boiling time (ranging between 27 and 36 minutes for 2.5 liters) than carbonized briquettes (ranging between 26 and 41 minutes). Water hyacinth alone produced briquettes with low calorific values (16.22 MJ/kg), however, calorific values increased when mixed with banana (20.79 MJ/kg) or pineapple peels (20.55 MJ/kg). The findings reveal crucial information on how agricultural wastes might be used to augment the energy sources pool in order to protect the environment and creating social stability in the community.

“…In the literature, there are some studies regarding the production of briquettes from various waste types, such as cashew nut shells and areca nuts [14,15], sawdust admixture [16], sawdust, rice and coconut husks [17], cassava waste [18], banana peel, corn husk and their combination [19], and maize cobs [20,21]. Bot et al [22] investigated the production process of briquettes from coconut shells, banana peels, sugarcane bagasse, and rattan waste and concluded that from the analyzed waste types, coconut husks had reduced mass loss and good combustion properties. Lubwama et al [23] demonstrated that rice and coffee husks briquettes had superior thermal efficiency compared to groundnut shells.…”

The large amount of biomass waste generated by vineyard pruning causes many environmental concerns. The production of briquettes represents an alternative to obtaining a value-added product. The transformation of vineyard wastes into briquettes could produce a densified product having high energy potential. The study investigates the production and chemical, structural, and thermal characterization of briquettes. The thermogravimetric analysis (TGA) shows that the briquettes have different stages of decomposition depending on temperature, such as drying, heating, devolatilization, and char aggregation. All the briquettes are decomposed around 600 °C. The analysis by X-Ray diffraction (XRD) shows the crystallinity of briquettes. The pollutant emissions resulted from briquettes burning were measured as 444.7 mg N−1m−1 nitrogen oxide (NOX), 157.0 mg N−1m−1 sulphur dioxide (SO2) and 2165.0 mg N−1m−1 carbon monoxide (CO). The flue gases are below the admitted limits, with the exception of carbon monoxide content due to the incomplete combustion and high lignin content. Therefore, it can be concluded that briquettes produced from vineyard wastes have similar properties to briquettes produced from wood. This study demonstrates the potential of the obtained briquettes to replace the wood or charcoal through a desulphurization method.
