Gasification of Waste Materials: Technologies for Generating Energy, Gas and Chemicals from MSW, Biomass, Non-recycled Plastics, Sludges and Wet Solid Wastes explores the most recent gasification technologies developing worldwide to convert waste solids to energy and synthesis gas and chemical products. The authors examine the thermodynamic aspects, accepted reaction mechanisms and kinetic constraints of using municipal solid waste (MSW), biomass, non-recycled plastics (NRP), sludges and wet solid wastes as feedstock. They identify the distinctions between pyrolysis, gasification, plasma, hydrothermal gasification, and supercritical systems. A comprehensive summary of laboratory and demonstration activities is presented, as well as field scale systems that have been in operation using solid waste streams as input, highlighting their areas of disconnect and alignment. The book also provides a summary of information on emissions from the stack, comparing them with other thermal conversion systems using similar feedstock. It then goes on to assess the areas that must be improved to ensure gasification systems become as successful as combustion systems operating on waste streams, ranging from feedstock processing to gasifier output gas clean-up, downstream system requirements and corrosion. The economics and future projections for waste gasification systems are also discussed. For its consolidation of the current technical knowledge, this text is recommended for engineering researchers, graduate students, industry professionals, municipal engineers and decision makers when planning, designing and deploying waste to energy projects, especially those using MSW as feedstock. Provides field demonstrations of large scale systems, their results and the challenges that need to be overcome when developing commercial applications and possible solutions Presents the most recent technologies in lab and demonstration scale Examines the critical development needs and real life challenges for the deployment of waste to energy technologies Provides information on the economics and sustainability of these technologies, as well as their future perspectives

This book provides a detailed overview of aspects related to the overall provision chain for biokerosene as part of the global civil aviation business. Starting with a review of the current market situation for aviation fuels and airplanes and their demands, it then presents in-depth descriptions of classical and especially new types of non-edible biomass feedstock suitable for biokerosene provision. Subsequent chapters discuss those fuel provision processes that are already available and those still under development based on various biomass feedstock materials, and present e.g. an overview of the current state of the art in the production of a liquid biomass-based fuel fulfilling the specifications for kerosene. Further, given the growing interest of the aviation industry and airlines in biofuels for aviation, the experiences of an air-carrier are presented. In closing, the book provides a market outlook for biokerosene. Addressing a broad range of aspects related to the pros and cons of biokerosene as a renewable fuel for aviation, the book offers a unique resource.

Die Offshore-Windenergie wird in der zukünftigen Stromversorgung eine entscheidende Rolle spielen. Diese Entwicklung steht aber gerade erst an ihrem Anfang. Ein großes Team aus Forschung, Industrie, Verwaltung und Politik hat sich deshalb zum Ziel gesetzt, die aktuellen und grundlegenden Fragen der Offshore-Windenergienutzung zu bearbeiten. Über 100 Forscher der RAVE-Initiative (Research at alpha ventus) arbeiteten in interdisziplinären Forschungsprojekten daran, unser Wissen zu erweitern und anwendungsorientierte Lösungen für die Offshore-Windenergie zu finden. Damit tragen sie dazu bei, die Offshore-Windenergie als eine zuverlässige, nachhaltige und kostengünstige Energiequelle auf Dauer zu etablieren. Im Testfeld alpha ventus, Deutschlands erstem Offshore-Windpark, wurden die Voraussetzungen für diese Forschung geschaffen. Der Windpark wurde mit umfangreicher Messtechnik ausgestattet: Über 1200 Messgrößen werden aufgezeichnet und sind über ein zentrales Forschungsarchiv zugänglich. Die Forscher der RAVE-Initiative haben somit die weltweit einmalige Möglichkeit, eine Vielzahl von Messdaten aus einem operativen Windpark zu nutzen. Die Auswertungen erfolgen dezentral an Forschungseinrichtungen im gesamten Bundesgebiet. Über Ziele, Methoden und Schwierigkeiten der RAVE-Forschungsprojekte wird in allgemeinverständlicher Form berichtet und die Ergebnisse sowie ihre Bedeutung für die weitere Nutzung der Offshore-Windenergie dargestellt. Der Leser erhält somit einen Überblick über den aktuellen Stand der Offshore-Windenergieforschung und die Ergebnisse der Forschungsarbeiten.
