“…The use of fossil fuels for energy purposes leads to a constant increase in the concentration of pollutants (CO 2 , CO, SO x , NO x , and other harmful oxides in the atmosphere) which cause global warming and have other negative impacts, such as acid rain and photochemical smog [18]. The last century was predominantly marked by the use of fossil fuels in energy production [19], but the beginning of the twenty-first century saw enormous efforts made in order to mitigate the effects of global warming caused by CO 2 emissions in the atmosphere [20]. Those were the exact endeavors in which sustainable development was grounded, a development that implies keeping a balance between the use, saving, and renewal of all resources [21], and not their uncontrolled expenditure to the detriment of future generations [22].…”

This research analyzed the degree of utilization of the agricultural biomass for energy purposes (combustion), in order to indicate the reasons that limit its use. The biomass potential was studied by means of the methodology of the biomass potential, whereas the factors suggesting a low degree of biomass utilization were identified by means of factor analysis. The research results reveal that there is an enormous potential of the unused agricultural biomass. This dissertation research significantly contributes to the establishment of a genuine mathematical model based on multiple linear regression. The solution obtained by this analysis, in both a mathematical and a scientific manner, conveys the primary reasons for an insufficient utilization of the biomass for energy purposes. Moreover, the paper suggests the measures to be applied for a more substantial use of this renewable source of energy and presents the expected benefits to be gained.

“…As for the phenomenon of GHG emissions as a result of energy consumption, both [22,23] indicated that the use of fossil fuel sources for energy purposes leads to an increase in pollutants with different GHG emissions, such as CO 2 , CO, SO x , NO x , etc., that cause global warming and have other negative impacts. Therefore, in the last century, the use of fossil fuels in energy production was predominantly marked, as mentioned by [24]. In this regard, at the beginning of the 21st century, many efforts were taken to mitigate the CO 2 emissions in the atmosphere that contribute to the global warming phenomenon [25].…”

Facing severe climate change, preserving the environment, and promoting sustainable development necessitate innovative global solutions such as waste recycling, extracting value-added by-products, and transitioning from traditional to renewable energy sources. Accordingly, this study aims to repurpose fish waste into valuable, nutritionally rich products and extract essential chemical compounds such as proteins and oils using a newly developed hybrid solar dryer (HSD). This proposed HSD aims to produce thermal energy for drying fish waste through the combined use of solar collectors and solar panels. The HSD, primarily composed of a solar collector, drying chamber, auxiliary heating system, solar panels, battery, pump, heating tank, control panel, and charging unit, has been designed for the effective drying of fish waste. We subjected the fish waste samples to controlled drying at three distinct temperatures: 45, 50, and 55 °C. The results indicated a reduction in moisture content from 75.2% to 24.8% within drying times of 10, 7, and 5 h, respectively, at these temperatures. Moreover, maximum drying rates of 1.10, 1.22, and 1.41 kgH2O/kg dry material/h were recorded at 45, 50, and 55 °C, respectively. Remarkable energy efficiency was also observed in the HSD’s operation, with savings of 79.2%, 75.8%, and 62.2% at each respective temperature. Notably, with an increase in drying temperature, the microbial load, crude lipid, and moisture content decreased, while the crude protein and ash content increased. The outcomes of this study indicate that the practical, solar-powered HSD can recycle fish waste, enhance its value, and reduce the carbon footprint of processing operations. This sustainable approach, underpinned by renewable energy, offers significant environmental preservation and a reduction in fossil fuel reliance for industrial operations.

“…When the temperatures are high enough (depending on the alkali metal content), the alkali metal compounds form slags in the form of aluminosilicates (Paneru et al, 2016). Besides alkali metal, silica, alkaline earth metal, and other elements are the significant ash forming elements for biomass (Lateef et al, 2020;Tabish et al, 2021;Zafar et al, 2020); the combination of biomass inorganic and organic ash can be as high as 20.1% (Vassilev et al, 2010). Another study reported that the ranges are 1 to 15%, depending on the type of biomass.…”

“…This condition will incur more costs for the commercial operation. It is reported that acid leaching has reduced the fuel's calorific value (Tabish et al, 2021;Zafar et al, 2020), making biomass more acidic, overreacting with biomass, taking a long time, and requiring a dedicated facility to do so. The fuel and wastewater will be acidic after the process.…”

“…Water leaching also has the same problem with its wastewater disposal; however, it is less harmful to the environment since this wastewater can be treated in a typical effluent pond after the process. The calorific value of the biomass becomes lower after certain types and concentrations of acid leaching may be due to the chemical reaction of biomass with acid, dissolving and reducing the biomass fibrous components (Zafar et al, 2020).…”

This study highlights the leaching process of biomass and food waste (FW), which reduces potassium and sodium content to more than 80% and improves its quality to be used as fuel. Alternative fuels with high water content, especially from FW and the palm oil industry, represent the majority of alternative resources in Malaysia. However, the combustion of these fuels often causes more ash-related problems such as fouling, slagging, and higher particle emissions compared to other fuel types. Water leaching is a pre-treatment process that has a great potential to alleviate the deposition problems caused by the thermal and chemical reactions of the biomass and FW elements during its combustion and thus increase their value. This study compared the fuel characteristics and water leaching effect to the selected fuels with specific water ratios for 5 minutes. Energy-dispersive X-ray spectroscopy (EDX) was used to determine water leaching effectiveness to compare the relative fuel composition after leaching. Leaching results were simulated using FactSage software to predict slag formation in treated and untreated samples during combustion at 650, 800, and 950°C. Simulated results show significant slagging formation reduction following the water leaching process onto the samples. Simulating the particulate and ash compositions paves the path to formulating strategic assessment techniques to reduce their emissions and slagging tendencies.
