    Waste to Energy Management
    (Elsevier, 2025) Yagmur Goren, A.Y.; Kalinci, Y.; Dincer, I.
    Today, the world faces growing challenges with waste problems since people have moved the problems from past to future. The key question is: is waste a problem or a resource? The correct response to this question can be found by investigating, in more detail, the types of waste and implemented waste management methods. The chapter consists of six main sections. The first section is focused on classification, which explains what waste is and categorizes it according to the producer (e.g., municipal, industrial, and hazardous) and chemical composition (for instance, organic, inorganic, and microbiological). The second section presents legislative trends. It is seen that the waste management legislations are changing from country to country. Also, it can change over time because every technological development emerges its waste. The third section covers waste management methods such as recycling, refuse-derived fuel, landfill, and thermal methods. The landfill method is the oldest and the cheapest one. It is seen that the method will continue in the near future, too, though a lot of legal regulations have been made to reduce its usage. Thermal methods are commonly used in the industrial sector. Hence, thermal methods such as incineration, pyrolysis, and gasification are examined in detail. Considering environmental issues, thermal technology moves toward gasification systems to reduce greenhouse gas emissions and the formation of by-products. The fourth section presents illustrative examples related to using waste management methods or their combinations. Further, a case study, which consists of a circulated fluidized bed gasification system, is investigated from the exergy and exergoeconomic points of view. The chapter presents exergy and exergoeconomic analyses in detail. The analyses show that it can produce 1.17 MWe power and 0.521kg/s hydrogen with 3.33 $/kg cost from 8.5kg/s biomass waste. Finally, future scenarios for waste management are investigated. Also, to achieve zero waste targets in the future, circular economy and industrial symbiosis concepts are examined, and some successful examples from around the world are presented. © 2025 Elsevier Inc.

    Biomass-Based Polygeneration Systems With Hydrogen Production: a Concise Review and Case Study
    (Springer Science and Business Media Deutschland GmbH, 2024) Hajimohammadi Tabriz,Z.; Mohammadpourfard,M.; Gökçen Akkurt,G.; Çağlar,B.
    This chapter discusses the importance of biomass-based polygeneration systems in producing hydrogen as a clean and safe energy carrier. The benefits of polygeneration systems, which can produce multiple products and minimize waste, are highlighted, and the need for clean and efficient hydrogen production is emphasized. This study gives a brief overview of hydrogen production from biomass-based polygeneration systems, which examines the systems in two main classifications: systems that use biomass as a potential and rich source of hydrogen and systems that exploit the energy content of biomass to run hydrogen production units. Furthermore, a new multigeneration system with hydrogen production has been introduced and thermodynamically evaluated. Also, its results have been obtained in a real situation. Overall, this chapter offers insights into the potential of biomass-based polygeneration systems in meeting energy demands while reducing environmental impact. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
