Das Projekt "D 5.1: Analysis of nutrient flow in resource-limited aquaculture systems in Son La Province, Northern Vietnam" wird vom Umweltbundesamt gefördert und von Universität Hohenheim, Institut für Tierproduktion in den Tropen und Subtropen (480), Fachgebiet Aquakultur-Systeme und Tierernährung in den Tropen und Subtropen (490i) durchgeführt.
Das Projekt "Cycling resources embedded in systems containing Light Emitting Diodes (CYCLED)" wird vom Umweltbundesamt gefördert und von Fraunhofer-Institut für Optronik, Systemtechnik und Bildauswertung durchgeführt. Objective: The project cycLED aims at optimising the flows of resources over all life-cycle phases of Light Emitting Diodes (LED) products. The energy saving potential for LEDs is significant, and the strategic importance of the LED technology is reflected in the current and upcoming market development. However, LED-based product systems contain many resources like indium, gallium or rare earth metals. Some of these substances are classified as critical raw materials at EU level. Therefore, if the current expansion of LED technologies is most welcomed from an economic and energy point of view, it requires optimising resource flows and addressing key societal issues. To strengthen the emerging LED market in Europe, cycLED focuses on improvement of the material flows and policy measures to remove barriers for LED technology dissemination. Innovation is needed to achieve an efficient management of the different materials used in LED systems, so that the growth of the LED-related markets is decoupled from resource depletion. A material flow analysis will first be conducted to obtain an overview of the most relevant materials contained in LED products, their origin and the situation regarding recycling. Further research will focus on the different life-cycle phases (production and manufacturing, assembling, use and material recycling) to provide overall solutions to improve the resource flows. These results will be combined to develop and implement solutions regarding product design for eco-innovation, adaptation of business models and overcoming of barriers to diffusion. Work packages dedicated to the development of indicators measuring the eco-innovation and to the dissemination of the results will accompany the research. The impacts of cycLED relate to resource savings, reduction of production costs, increase of competitiveness, creation of jobs and capacity building.
Das Projekt "National Contact Points for Climate action, Raw materials, Environment and Resource Efficiency (NCPs CaRE)" wird vom Umweltbundesamt gefördert und von Forschungszentrum Jülich GmbH durchgeführt.
Das Projekt "Wechselwirkungen zwischen Hydrodynamik und Biofilmeigenschaften und -funktion in Fliessgewässern" wird vom Umweltbundesamt gefördert und von Rheinland-Pfälzische Technische Universität Kaiserslautern-Landau, Institut für Umweltwissenschaften durchgeführt. Biofilms constitute an integral part of aquatic ecosystems and are controlled by many factors such as light, grazing, resource availability, water chemistry and flow conditions. Natural mountainous streams exhibit a heterogeneous river bed ranging from boulders to small sediment grains like sand and thus provoking high spatio-temporal variability of the flow field. Here, flow hydrodynamics become a dominant factor shaping biofilm morphology such as biomass and architecture and controlling biofilm community composition through drag forces on the one side and supply of resources through mass transfer processes on the other. Current knowledge of the interactions between flow hydrodynamics and biofilm attributes is based on a few idealized case studies and is lacking a link to the consequences for stream ecosystem functioning like, e.g., nitrogen uptake. Previous studies have been restricted to flume experiments where the highly complex flow field of natural streams cannot be reconstructed to the full extent. In a novel approach we are aiming at linking detailed investigations on river bed heterogeneity and associated development of flow fields to biofilm characteristics and the consequences for nitrogen uptake. In order to avoid artifacts of mesocosm studies we will conduct experiments and measurements in both, field and mesocosm environments, thereby providing the advantages of real stream scale results and detailed flume studies on basic processes of mass transfer. Furthermore, we will integrate not only results from the river patch scale but also the role of biofilms on the river reach scale. This highly interdisciplinary research will provide mechanistic understanding of nitrogen uptake of biofilms under varying flow conditions and will thereby extend current knowledge on the regulation of whole stream ecosystems processes in mountainous streams.
Das Projekt "REsource Management in Peri-urban AReas: Going Beyond Urban Metabolism (REPAiR)" wird vom Umweltbundesamt gefördert und von Technische Universiteit Delft durchgeführt. A shift towards a more circular economy is crucial to achieve more sustainable and inclusive growth. Our objective is to provide local and regional authorities with an innovative transdisciplinary open source geodesign decision support environment (GDSE) developed and implemented in living labs in six metropolitan areas. The GDSE allows creating integrated, place-based eco-innovative spatial development strategies aiming at a quantitative reduction of waste flows in the strategic interface of peri-urban areas. These strategies will promote the use of waste as a resource, thus support the on-going initiatives of the EC towards establishing a strong circular economy. The identification of such eco-innovative strategies will be based on the integration of life cycle thinking and geodesign to operationalise urban metabolism. Our approach differs from previous UM as we introduce a reversed material flow accounting to collect data accurate and detailed enough for the design of a variety of solutions to place-based challenges. The developed impact and decision models allow quantification and validation of alternative solution paths and therefore promote sustainable urban development built on near-field synergies between the built and natural environments. This will be achieved by quantifying and tracking essential resource flows, mapping and quantification of negative and positive effects of present and future resource flows, and the determination of a set of indicators to inform decision makers concerning the optimization of (re-)use of resources. The GDSE will be open source. With a budget of €5 million, REPAiR funds a consortium rich in experience in waste and resource management, spatial decision support, territorial governance, spatial planning and urban design, and has deep knowledge of the 6 case study areas. REPAiR is supported by a user board, of key stakeholders for the development of CE as well as local authorities, who are heavily involved in the GDSE testing.
Das Projekt "Safety and quality assurance measures along the pellets supply chain (SAFEPELLETS)" wird vom Umweltbundesamt gefördert und von Bioenergy 2020+ GmbH, Firmensitz Graz durchgeführt. Isolated incidents due to increased, toxic emissions in pellet storages have aroused great relevance and urgency on operational and customer safety in wood pellet supply chains. Reportedly two cases of death have occurred in large size vessels for ocean transportation and in harbour facilities. Another three incidents were reported in end-users storage rooms, the last of which resulted in the death of a German engineer. Furthermore, measurements in pellet storages show significantly increased CO concentrations for a relevant number of storages. Until now a definitive cause for increased CO concentration could not be found. Within this project the different approaches and results on safety in pellet supply chains are linked with each other and integrated to a supranational scope. This is of great importance as pellet markets are no longer isolated, but increasingly grow to international resource flows. In this regard, decisive parameters like the amount of off-gasses and the potential for self-heating related to the time from pellet production to end use as well as the raw material composition of pellets resulting from their origin have to be investigated within international scope. The proposed project aims to answer the question, where and under which conditions off-gassing and self-heating from biomass pellets occurs and what measures can be undertaken to reduce these risks. In turn, this project will end out into a draft for setting an international standard on safety measures and inspection methods along the whole pellets supply chain (e.g. by developing Material Safety Data Sheets for wood pellets). This safety issue is decisive for the further extension of pellets markets and thereby reflects high relevance for all enterprises in the pellet utilisation chain.
