“…The fuel briquettes underwent the water boiling test (WBT) through the process of boiling 500 mL of tap water on a household updraft biomass gas stove (Mainkaew, Pattiya, & Jansri 2023;Kole et al 2022). Two piles of longan branches, each weighing 100 g, were used to ignite the stove, which was then left to burn for 2 min.…”

Elephant dung is the camp's undigested fiber waste. For more effective waste management, the conversion of dung to torrefied solid and the formation of solid torrefied into fuel briquettes, as well as their properties, were investigated. The dung was improved through torrefaction at 280ºC for 150 sec in a pilot-scale reactor with a feeding rate of 600 g/h. The torrefied elephant dung had 17 MJ/kg of HHV, a solid yield of 79%, and a fixed carbon content of 20%. A mixture of torrefied dung, binder, and water was compressed at 40 bars to a density of 860 kg/m3, or 12 GJ/m3. Their H/C and O/C atomic ratios were in the range of typical biomass. However, due to their moisture content of over 7%, the HHV of the fuel briquettes was below 17 MJ/kg. Moreover, their thermal efficiency was less than 7% due to durability issues, despite having a great fuel ratio and thermal stability. The combustion of these briquettes resulted in less than 850 ppm of CO. To improve the combustibility of this solid biofuel, it is recommended to develop a production process and a suitable stove specifically for these briquettes.

“…To address these challenges, there is an urgent need to shift towards renewable energy sources [5][6][7] or implement effective strategies for managing energy through techniques such as energy recovery [8][9][10][11][12][13][14]. Renewable resources like wind power [15][16], solar thermal technologies [17][18][19][20][21][22][23][24], biomass utilization [25,26], and geothermal options [27,28] have emerged as promising alternatives that can mitigate reliance on fossil fuels. Additionally, reducing waste in existing systems by implementing measures to capture lost or dissipated energies are also gaining attention.…”

The increasing global demand for renewable energy sources underscores the significance of Solar Water Heating Systems (SWHS), emphasizing the need for thorough research and analysis in this domain. SWHS play a pivotal role in addressing energy efficiency and environmental sustainability, making it imperative to conduct in-depth studies on their utilization. Hence, this paper aims to provide a comprehensive overview of SWHS. It starts by explaining the principles behind these systems, including their components and classification. Moreover, this review consolidates various studies that have been conducted on SWHS to highlight both their advantages and disadvantages. Additionally, a case study is conducted in which it takes into consideration important economic and environmental factors. In particular, it focuses on several scenarios present in Lebanon such as family homes, schools, restaurants hotels and gyms to estimate potential cost savings achieved through implementing SWHS as opposed to relying solely on electric heaters. Furthermore, this investigation also examines the corresponding payback period associated with adopting SWHS along with assessing the significant reduction in carbon dioxide emissions possible if these systems were widely implemented. The findings of the study demonstrate that there is a direct correlation between the extent to which SWHS are utilized and both the payback period and reduction in CO2 emissions. It was observed that when SWHS are used more frequently, with a high percentage of time (Pr=0.9), significant advantages can be achieved. For instance, for different types of establishments such as family homes, schools, restaurants, hotels, and gyms, it was estimated that average payback periods would be 14.2 years, 4.6 years, 9.2 years, 4.4 years, and 5.3 years, respectively. These results indicate that adopting a greater dependency on SWHSs not only leads to quicker cost recovery but also significantly contributes towards reducing carbon dioxide emissions. The analysis reveals that the yearly decrease in carbon dioxide emissions per individual is 0.16 t within a household, 0.016 t per student in an educational institution, 0.04 t per customer within a dining establishment, 0.37 t for each occupied bed in a hotel accommodation, and 0.11 t per individual at a gym. This paper serves as guidelines to SWH community. Additionally, it adds a practical insights into economic and environmental issues relevant to both Lebanon and countries with similar climates.
