“…After that, the amount of water displaced inside the burette was recorded daily for 15 days and was corrected to standard temperature and pressure of 0 ℃ and 1 atm. In theory, methane gas production accounted for 70% of total production of biogas, and about 30% is in the form of carbon dioxide and other traces number of gases [14].…”

Biogas is an environmentally friendly, clean, and low-cost renewable energy source. This alternate sustainable source can be used for heat, power, or fuel and making it a good alternative for renewable energy. Biogas can be produced through anaerobic digestion of biodegradable organic materials without oxygen and can be improved by performing thermal treatment. In this study, biogas was recovered using treated and untreated food waste. The characterisation of food waste for its suitability for an anaerobic digestion process was studied by its total solids, volatile solids, pH value, and C/N ratio, following the APHA standard. The anaerobic digestion was treated in a water bath at a temperature of 70 °C for 45 minutes. The Biochemical Methane Potential method was conducted to determine the biogas production from treated and untreated anaerobic digestion. The treated and untreated anaerobic digestion were anaerobically digested at a mesophilic temperature of 37 °C and at a speed of 100 rpm for 15 days. The biogas produced was measured daily by using water displacement method. The total production of biogas for treated anaerobic digestion was 198.70 mL, meanwhile for untreated anaerobic digestion was 185.50 mL. Treated anaerobic digestion showed a slightly higher production of biogas in 15 days by 13.2 mL. The biogas yield obtained for treated and untreated anaerobic digestion was 51.21 mL/g and 47.80 mL/g for every 1 g of total wet sample. This study found that thermal treatment of anaerobic digestion helps in the degradation of organic content in food waste for anaerobic digestion, which leads to higher biogas recovery.

“…Anaerobic digestion (AD), as detailed by Kumar and Ankaram (2019), is a method that transforms organic substances in an environment devoid of oxygen [48]. This process leads to the production of methane-rich biogas and involves a sequence of interrelated stages, including hydrolysis, fermentation, acetogenesis, and methanogenesis, as outlined by Sangeetha et al (2020) [49]. During AD, microbes break down the organic components of waste to produce biogas that is composed of 40-65% methane (CH 4 ), 35-55% CO 2 , and other trace gases like hydrogen (H 2 ) and H 2 S. Additionally, the process yields a nutrientrich residue known as digestate, which can be used as a soil conditioner or source of C, N, and P, as reported by Ghosh et al ( 2020) and Wang and Lee (2021) [50,51].…”

With the global population continuing to increase, the demand for food and energy has escalated, resulting in severe environmental pressures. Traditional methods of food and energy production have left a significant footprint on the environment, primarily due to the emission of greenhouse gases and a notable surge in waste production. Nevertheless, scientists have recently focused on developing sustainable solutions by managing biomass waste and converting it into useful products. Various biomass conversion technologies, including pyrolysis, gasification, and fermentation, have emerged to transform waste materials into valuable commodities like biofuels, fertilizers, and chemicals. These technologies present an alternative to conventional energy production methods and decrease reliance on non-renewable resources. Furthermore, the by-products generated through biomass conversion, such as biochar, possess utility as valuable soil amendments. This review emphasizes the potential of biomass conversion technologies in providing sustainable solutions for waste management, food and energy production, and reducing negative environmental impacts while providing valuable by-products for agricultural use. The focus is on Lebanon, which is facing a waste and energy crisis, with an aim to encourage and promote sustainable practices by highlighting different green waste management technologies. Focusing on the application of biochar in soil, our goal is to provide cost-effective and eco-friendly solutions to various agricultural and environmental challenges in Lebanon. This includes using biochar from biomass waste as a soil amendment to boost crop yields, remediate soil pollution, reduce soil drought stress, and address other related issues.

“…The waste materials will be transformed into methane and carbon dioxide in anaerobic digestion and it can be enhanced by special pathways ( Li et al., 2019 ). General steps of anaerobic digestion include hydrolysis, fermentation, acetogenesis, and methanogenesis ( Sangeetha et al., 2020 ; Wang et al., 2018 ). For Food waste (FQ) various stages of anaerobic digestion ( Wang et al., 2018 ) are there, initially, in aerobic digestion process, the collected biomass of animal waste, plant waste, slurry and manure, food and amenity wastes were transferred into the sealed container (absence of oxygen) or biogas reactor.…”
