Book Description
Waste Wood and wood by-products have the potential to become attractive alternative sources of raw materials. Their efficient use is important due to the rising demand and limited supply of forest wood. Cascade utilization is gaining interest as a strategy to bridge the gap between rising wood demand and fresh wood availability. However, the economic and environmental impacts of a cascading system for wood-based products are not fully known. In this work, an investigation is conducted to determine the consequences of cascade utilization for the economic and environmental performance of logistics networks for wood flows. Two case studies in Lower Saxony consider five wood products, including medium density fiber (MDF), oriented strand board (OSB), particleboard, coated paper, and wood pellets. In the first case study, an approach for decision support is developed that consists of a mixed-integer linear programming (MILP) model. In the first case study, the MILP model is used for minimizing the costs of the logistics network for three scenarios. Then the UMBERTO software is applied to determine the quantity of CO2e of the minimized logistics network. In the second case study, the MILP model is enhanced using two objective functions, as cost and global warming potential (GWP) are considered simultaneously. In this case study, it is observed that environmental parameters such as CO2 emissions can also be implemented in the MILP. The utilization of a multi-objective optimization model brings new perspectives (the trade-off between two contradictory objective functions, for instance) in comparison to the first case study, in which CO2 is calculated as an off-line step after logistics costs are minimized. Altholz und Holz-Nebenprodukte besitzen das Potenzial, attraktive, alternative Rohstoffquellen zu werden. Ihre effiziente Nutzung ist von hoher Relevanz, da die Nachfrage nach Holz steigt und die Versorgung mit Holz aus Wäldern begrenzt ist. Um die Lücke zwischen der wachsenden Holznachfrage und - verfügbarkeit zu überbrücken, ist die Kaskadennutzung eine Strategie, welche zunehmendes Interesse erfährt. Allerdings sind die wirtschaftlichen und ökologischen Auswirkungen eines Kaskadensystems für Holzprodukte nicht vollständig bekannt. In dieser Arbeit wird eine Untersuchung durchgeführt, um die Folgen der Kaskadennutzung auf die Wirtschafts - und Umweltleistung von Logistiknetzwerken für Holzströme zu bestimmen. Im Rahmen von zwei Fallstudien in Niedersachsen werden fünf Holzprodukte, einschließlich mitteldichten Fasern (MDF), OSB-Platten (OSB), Spanplatten, beschichtetem Papier und Holz-Pellets betrachtet. In der ersten Fallstudie wird ein Ansatz zur Entscheidungsunterstützung entwickelt, der aus einem Mixed-Integer Linear Programming (MILP)-Modell besteht. Das MILP-Modell wird zuerst in drei verschiedenen Szenarien zur Minimierung der Logistikkosten angewendet. Mithilfe der UMBERTO-Software wird anschließend die Menge von CO2e bestimmt. In der zweiten Fallstudie wird das Modell für zwei Zielfunktionen weiterentwickelt und eingesetzt, bei denen die Kosten und das Treibhausgaspotenzial gleichzeitig betrachtet werden. Diese Fallstudie zeigt, dass auch Umweltparameter wie CO2-Emissionen mit MILP umgesetzt werden können. Die Verwendung eines Mehrzieloptimierungsmodells ermöglicht die Betrachtung neuer Perspektiven (zum Beispiel den Trade-off zwischen zwei widersprüchlichen Zielfunktionen) im Vergleich zur ersten Fallstudie, in welcher CO2-Emissionen in einem Offline-Schritt nach der Minimierung der Logistikkosten minimiert werden.

Book Description
The increasing scarcity of land and the ever-rising amount of waste produced worldwide, coupled with the consequent change of focus by policy makers from waste disposal and recovery to waste prevention is boosting research in the 'economics of waste'. This volume addresses waste-management and waste-disposal issues, embedding them in spatial, systemic and trade-related frameworks. The collection is policy oriented, including socio-economic and political science perspectives in order to provide an understanding of real world phenomena, and thus maximize its value for policy making. The book includes contributions on the linkages between income and waste generation and landfilling (such as the ‘waste Kuznets curve’ conceptual framework), in addition to papers that bring together policy-oriented analysis of instrument effectiveness and the spatial nature of waste phenomena. On top of this, there are pieces of research emphasizing technological spillovers and trade at interregional and intercountry levels. The comparative analysis of policy effectiveness and efficiency at the regional and country levels is also covered, including the assessment of the potential role of illegal management of waste in determining waste performance. To give a spatial and comparative flavour, the book includes work on the evaluation of waste-related externalities, with examples covering household, industrial and special waste. The wide set of methodologies and issues included in this book make it a comprehensive starting point for scholars and policy makers interested in waste-related research.

Book Description
Closed-loop supply chain activities such as remanufacturing, recycling, dismantling for spare parts, and reverse logistics have helped many companies tap into new revenue streams by finding secondary markets for their products, all while reducing their overall carbon footprint. Written by academic experts, in language that is accessible to practitioners, this authoritative resource examines recent research and case studies of companies running profitable reuse/remanufacture operations in various industries. It illustrates profitable practices in returned and recovered products, clearly explaining how to: design a reverse logistics network, conduct production planning, implement effective marketing strategies, and apply closed-loop supply chain strategies in industries besides manufacturing. From product development to materials to assembly and profitability, this complete resource explores the impact of these processes across all aspects of the supply chain.
