Summary: Food waste is a major emitter of greenhouse gases, causing environmental devastation. A significant amount of food, almost one-third, is wasted during the supply chain and harvesting process, resulting in a loss of $1 trillion annually. Various industries, such as beverage, dairy, fruit and vegetable, and cereal, contribute to the generation of different types of food waste, which can be used as feedstock in biorefineries to reduce environmental impacts and produce value-added products. Food waste biorefineries have the potential to support circular bioeconomy and address sustainability challenges.

Summary: Biofuels are sustainable, eco-friendly, and bio-economic alternatives to fossil fuels. They are classified into different generations based on production methods, cost-effective technology, and substrate used. While first and second-generation biofuels have limitations, third-generation biofuels show promise as environmentally friendly alternatives. Challenges still remain for commercialization, leading to the development of fourth-generation biofuels using innovative techniques. Further research and development are needed to overcome these challenges and pave the way for a sustainable bioeconomic pathway in the fuel industry.

Summary: The presence of emerging impurities in food waste, such as plastic, chopsticks, eggshell, and bones, has hindered the sustainable treatment and utilization of food waste. This study investigated the conversion of food waste into pyrolysis oil and evaluated the effect of different impurities. It was found that certain impurities, like polypropylene, improved the organic fraction of the pyrolysis oil, while others reduced the selectivity of hydrocarbons. The addition of treated eggshells and activated biochar as catalysts increased the production of aromatic and aliphatic hydrocarbons with higher heating values.

Summary: This paper compares the effects of two different chemical pretreatments on the characteristics of OPEFBs, methane production, digestate characteristics, and kinetic modelling. The results show that alkaline-treated OPEFBs have higher methane yields compared to acid-treated OPEFBs. The best treatment is the alkaline pre-treatment of P2N3, which leads to a 1.2-fold increase in methane yield. SEM-EDX analysis reveals that acid-treated OPEFBs have cell wall disruption and mineral loss, while alkaline-treated OPEFBs have more pores due to the release of silica and other chemicals. Both experimental data and models confirm P2N3 (3.8% NaOH) as the best results in terms of lignin reduction and methane production. Further investigations with a focus on sustainability and circular economy perspectives are needed.

Summary: This study compared the anaerobic digestion remediation of two marine algal biomass species, Tetraselmis suecica and Nannochloropsis oceanica, and found that Tetraselmis suecica had better methane production potential. Ultrasound treatment had a slight impact on the methane production potential of both Nannochloropsis oceanica and Tetraselmis suecica biomass, but ultrasound techniques can still be recommended for effective bioenergy production.
