Summary: Biorefineries have gained global attention as an alternative to conventional fuel production, but cost competitiveness remains a challenge. Policy actions, such as the Green Deal and the Circular Economy Action Plan, promote the maximization of the biomass-to-products value chain by utilizing valuable compounds in side-streams. Side-streams from corn and rapeseed-based biofuels industries contain bioactive compounds and proteins that are currently underutilized as animal feed, limiting their potential in industries such as food supplements, specialty chemicals, cosmetics, and household products. This research aims to assess the availability and future production rates of side-streams, such as corn oil, thin stillage, rapeseed meal, and other biodiesel and bioethanol production by-products, to facilitate their market penetration and technology upgrading. The findings suggest increasing availability of specified side-streams due to growing biofuel production and regional regulations. Further research could explore the types and regional availability of active compounds in these side-streams to stimulate further developments and investments.

Summary: Microalgae can convert CO2 into carbohydrates, lipids, and proteins, which can be transformed into renewable energy, chemicals, and materials. However, the difficult-to-degrade cell wall and lack of environmentally friendly pretreatment methods hinder the commercialization of microalgal biorefineries. This article discusses the chemical structure and rigidity of microalgae, and summarizes traditional pretreatment methods. Green solvents like ionic liquids, deep eutectic solvents, and natural deep eutectic solvents show promise in selectively extracting components from microalgae. Further research is needed for the deployment of carbon-neutral technologies, including the design of task-specific solvents, understanding their structural activity, and assessing their environmental toxicity and recyclability. Additionally, integrating microalgal industry with biorefineries can improve waste management, sustainability, and revenue.

Summary: The COVID-19 pandemic has caused a significant increase in plastic waste, such as disposable gloves, masks, tissues, and other PPE. Improper management of healthcare waste poses serious health hazards and challenges for solid waste management authorities. The incineration of COVID-19 medical waste generates microplastic particles, dioxins, furans, and toxic metals, which pose a threat to human and animal health. Degradation of microplastics by microorganisms can be a sustainable solution to mitigate the microplastic pollution caused by the pandemic.

Summary: To meet the growing energy needs and address the depletion of fossil resources, there is a need to shift from fossil-based feedstocks to organic waste for a competitive, resource-efficient, and low-carbon sustainable economy. Chemical routes for fuel and chemical production have low production costs, but the use of toxic and expensive catalysts make the process unsustainable. Utilizing renewable resources for bioprocessing with a multi-product approach improves resource utilization and contributes to the green economy.

Summary: Adding magnetite (Fe3O4) can reduce the by-products generated from acid hydrolysis of biomass and enhance hydrogen production. This study extracted sugars from Gelidium amansii through acid hydrolysis and evaluated hydrogen production with magnetite supplementation. The addition of magnetite at a concentration of 1.3 g/L or lower increased hydrogen production by 11.4% on average, especially for the main by-product, 5-hydroxymethylfurfural (5-HMF). This strategy could optimize biohydrogen production using Gelidium amansii and reduce detoxification costs.

Summary: The rapid increase in municipal solid waste in developing countries is causing environmental problems such as contamination of air, water, and soil. The current management of waste faces challenges such as lack of technology, strategic management, social awareness, and public participation. Efforts have been made globally to develop systematic collection and transportation methods using advanced technology, but few studies have addressed this issue in low- and middle-income countries due to a lack of reliable resources and data. This paper discusses the challenges in collection and transportation methods and highlights the application of information communication technology in monitoring and managing waste.
