This Thünen Working Paper presents the results of the research project "Joint Project: Expansion of a systematic monitoring of the bioeconomy - consolidation phase." The project aimed to further develop the monitoring concept for the German bioeconomy and to update initial monitoring results....

Sustainability management requires differentiated information on the environmental and economic consequences of material demand's increasing and decreasing factors. Material flow cost accounting fails to provide this information due to the common undifferentiated determination of realized costs...

Batang Regency encountered persistent waste management challenges, requiring effective mitigation strategies. This study evaluated residential waste management utilizing life cycle assessment (LCA) and material flow analysis (MFA) to propose sustainable plans. Three scenarios were compared: the...

Background: This study addresses optimising fleet size in a system with a heterogeneous truck fleet, aiming to minimise transportation costs in interfacility material transfer operations. Methods: The material transfer process is modelled using a closed queueing network (CQN) that considers...

Background: This review addresses the emerging field of automated packing cells, which lies at the intersection of robotics and packing problems. Integrating these two fields is critical for optimizing logistics and e-commerce operations. The current literature focuses on packing problems or...

At present, anthropogenic systems are synonymous with linear economies that cause wide-spread resource waste and environmental degradation. Urban areas are hotspots for this behaviour due to their high population density and resource consumption. Changing this situation is limited by the lack of...

A circular economy requires managing and reducing the environmental and social impacts of products and materials across their lifecycle from production to end-of-life, including clean energy technologies. The unprecedented growth in wind turbine (WT) deployment in Australia as a clean energy...

Current levels of resource use and pollution emissions are responsible for the trespassing of most planetary boundaries. As such, operational and contextual analysis is needed to provide mitigation strategies and policies. This article aims to streamline Economy-Wide Material Flow Accounts...

Material Flow Analysis (MFA) has been widely used to understand the physical economy of the country and its implication on the economic and environmental issues. By subscribing to the data on Global Material Flow Database released by United Nations Environment Programme (UNEP) International...

Countries are responding to unsustainable resource extraction, rising emissions, and increasing waste streams by implementing national bioeconomy strategies. Assuming that the purpose of a bioeconomy is to replace fossil use by biogenic resource use, we estimate biomass and fossil raw material...

Materials handling is essentially related with production and manufacturing flow. Thus, it has direct impact on transit time, resource usage, and service levels. The logistics industry is identified to be a competitive environment, connected to the globalization phenomena, requires from...

Extremal materials are elastic metamaterials with rank-deficient elasticity tensor. Due to this novel property of the elasticity tensor, extremal materials (especially pentamode materials) show outstanding performance in various wave manipulation applications. However, until now there is still a...

The Nd doped LaB6 and La doped NdB6 was successfully synthesized from La2O3–B2O3–Mg blends by mechanochemical method. The Nd doped affects on crystal structure and electronic features were studied employing DFT. The high-energy ball milling carried out the synthesis reaction. The process...

A novel structure of Li/Na hybrid-ion batteries is proposed, using nonstoichiometric Li 2.7 V 2 .1 (PO 4 ) 3 /C nanocomposites as cathode and Na foil as anode with lithium-ion electrolyte (NSLVP-L). The discharge specific capacity of 132.99 mAh·g -1 is delivered at a current density of 100...

Die derzeitige Nutzung natürlicher Ressourcen überschreitet die planetaren Grenzen und gefährdet so die Widerstandsfähigkeit des Ökosystems Erde. Der wachsende Rohstoffverbrauch und die daraus resultierenden ebenfalls wachsenden Abfallmengen und Emissionen bedrohen die Umwelt und somit die...

Purpose: Through increasing individualization, volatile market demands or shorter product and innovation cycles, existing assembly systems in the automotive industry reach their limits. Different approaches are designed to address the need for adaptable systems. The Fluid Manufacturing System...

Purpose: This technical note provides the mathematical demonstration for obtaining the optimal aspect ratio for a rectangular storage area with a lateral receive/ship dock, representing the standard configuration of modern distribution centers and logistic warehouses. The proposed aspect ratio...

Material handling systems (MHS) are integral to logistics functions by providing various supports such as handling, moving, and storing materials in manufacturing and service organisations. This study considers determining the optimal size of a homogeneous fleet of trucks to be outsourced (or...

At a time when it is critically important to preserve natural resources and reduce the amount of man-made pollution, this article explores other potentials for materialism in today’s market economies. Based on a two-year ethnography in Poland, we learn from simplifiers who denounce current...

Steel is of extraordinary importance for the European economy as well as society, but is responsible for enormous energy consumption and greenhouse gas emissions. Therefore, steel flows are an obvious subject for the European climate protection. The quantification of steel stocks and flows is...

Thailand, like many countries around the world, is in the midst of a significant plastic waste crisis. In 2019, the government of Thailand released the Roadmap for Plastic Waste Management 2018-2030 and is developing the National action plan on Marine plastic debris to alleviate the current...
