The project's objective is to support JRC IPTS in revising the existing Ecolabel and GPP criteria of personal computers and notebook computers. The priority in this revision process is to first analyse which of the existing criteria and the supporting evidence are still valid and to identify the additional research that should be carried out. Potential additional criteria can be developed, if identified as necessary in the course of the study. The study starts with a definition of the scope; the necessarity for new or revised Ecolabel and GPP criteria is based on a market analysis and a technical analysis with research on the most significant environmental impacts during the whole life cycle of the products. This also includes the application of a consistent methodological approach regarding the hazardous substances criteria. Based on these findings, the improvement potential will be derived resulting in a proposal for a revised Ecolabel and GPP criteria set for desktop and notebook computers which will be discussed in a European stakeholder process.

Ziel der Forschungsarbeit ist die Klassifizierung von Boden-Biozönosen in ausgewählten Feldrainen. In drei Naturräumen (Lössböden der Jülicher Börde, Muschelkalkböden in Mainfranken und pleistozäne Sande bei Leipzig) werden typische Lebensgemeinschaften von Collembola und Gamasina (Taxozönosen) beschrieben. Der wesentliche Unterschied zu anderen Klassifikations-Ansätzen liegt in der induktiven Vorgehensweise: Biozönosen werden allein aufgrund der Artenzusammensetzung an den Standorten typisiert. Vegetationskundliche Kriterien dienen als entscheidendes Hilfsmittel zur Vorauswahl von Flächen mit ähnlichen Standortbedingungen. Hierbei wird gleichzeitig die aufgenommene Vegetation als ein weiteres Taxon der zu beschreibenden Biozönose angesehen. Die typische Artenzusammensetzung ist das integrierte Ergebnis aller denkbaren ökologischen Vorgänge. Ein Ziel der Arbeit ist somit die prospektive Formulierung von Erwartungswerten für Collembolen und Raubmilben auf der Basis vegetationskundlicher Daten. Es sollte daher möglich sein, dieses Mehrarten-System mit hoher Sensibilität zur Bioindikation von Standortveränderungen einzusetzen. Die Kenntnis der Artenstruktur wiederkehrender Lebensgemeinschaften kann der funktionellen Ökosystemforschung hilfreiche Hinweise bieten.
Das Projekt ÖkoKauf der Stadt Wien hat es sich zum Ziel gesetzt, durch die Erstellung von ökologischen Kriterien, Pilotprojekte und durch Bewusstseinsarbeit das Beschaffungswesen im Magistrat Wien weiter zu ökologisieren. In diesem Rahmen widmete sich der Arbeitskreis 'Desinfektionsmittel unter der Leitung der Wiener Umweltanwaltschaft (WUA) der Aufgabe, für Hygienefachleute ein Instrument zur Beurteilung der Auswirkungen von Desinfektionsmitteln auf Gesundheit und Umwelt zu erstellen. Das Österreichische Ökologie-Institut führte eine Daten- und Literaturrecherche durch, das Umweltbundesamt nahm ergän-zende ökotoxikologische Tests an Wirkstoffen und -produkten vor und 'die umweltberatung ermittelte stationsbezogene Desinfektionsmittelverbräuche in Wiener Krankenanstalten. Die Recherche- und Testergebnisse zu Desinfektionsmittelwirkstoffen und -produkten wurden in einer vom IFZ konzipierten und von der Magistratsabteilung 14 realisierten Datenbank zusammengefasst. Um die ökotoxikologischen Produkteigenschaften vergleichbar zu machen, wurde vom IFZ ein Bewertungsraster entwickelt und in die Datenbank integriert. Dabei werden nachteilige Wirkungen auf die Gesundheit anhand von vier Wirkungskategorien erfasst: Akute Giftigkeit; Reizwirkung auf die Haut; Sensibilisierung, allergenes Potenzial sowie Erbgutschädigende, krebserzeugende und fruchtschädigende Eigenschaften. Zusammen mit der Berücksichtigung des Verhaltens in Oberflächengewässern (Abbauverhalten, Bioakkumulationspotenzial, Toxizität für Wasserorganismen) sowie dem Verhalten in Kläranlagen werden insgesamt sechs Bewertungszahlen generiert, die auf einer Skala von 1 (vernachlässigbar) bis 5 (sehr hoch) das gesamte Gefährdungsprofil des Stoffes beschreiben sollen. Das Gefährdungsprofil eines Handelsproduktes errechnet sich aus den Gefährdungsprofilen der darin enthaltenen Wirkstoffe anhand eines Algorithmus: Dabei wird die Annahme getroffen, dass die Produkteigenschaften von der Konzentration der darin enthaltenen Wirkstoffe abhängen. Bei der Bewertung ist außerdem zu gewährleisten, dass ein Wirkstoff mit einem hohen Gefährdungspotenzial angemessen berücksichtigt wird, auch und gerade wenn seine Konzentration im Produkt gering ist. In der Literatur wird dazu eine logarithmische Skalierung vorgeschlagen. Die Bewertung berücksichtigt derzeit die Wirkstoffe sowie Anwendungsverdünnungen. Die Zusammenfassung der Produkte in Verwendungs- bzw. Expositionskategorien ermöglicht letztlich eine vergleichende Bewertung. Da das Bewertungsraster gerade auf eine vergleichende Bewertung von Produkten abzielt, unterliegt er einer ständigen kritischen Diskussion, die auch häufig von den Herstellern geführt wird. Dieser Umstand sowie das Faktum von Produktlebenszyklen erfordern ein ständiges Update der in der Datenbank enthaltenen Informationen und eine Anpassung des Bewertungsmodells an den aktuellen Stand von Forschung sowie Standards der Stoff- und Produktpolitik.
Climate change, population growth, land use changes and urbanisation and so forth forcing future generations to produce more with fewer resources. Hence innovative water harvesting approaches in combination with an integrated water management are urgently needed. In the past water harvesting was manly seen isolated and set into a bigger framework of a river basin. Overexploitation at one side necessarily leads to a shortage at the downstream region. This is especially true for basin closure. It is inevitable that integrated water management has to care about upstream/downstream interactions and between water harvesting and large scale irrigation at the catchment/river basin scale. The objective of this proposal is to set standards for water utilization on a basin (sub basin scale) to ensure food and water security in an equitable manner throughout the whole basin in the context of a range of dynamic global and regional pressures. There are numerous technologies for water harvesting available, but what is missing is an appropriate system design and synergies amongst farmers and other stakeholders. The concept of the project therefore is to links knowledge of water harvesting of different regions and analyse and investigate acceptance of systems. A SWOT analyses should be performed for each selected study region to have a sound base for highest investment benefits and also a risk analyses of investment. This analysis also enables the development of guidelines and criteria to transfer the various water harvesting technologies in different hydrological, biological and socio-economic conditions and to ensure integration of those technologies in the context of local and regional economical environment. The Definition of water harvesting for this project is an Integration/Synergies of/with farming systems and as a wider definition with respect to WHO, measures of conservation farming. The advantage of conservation farming is an easy to implementation, it is practical; and reduces loss of water. The prominent part of water storage with regard to water balance has to be recognized. For each basin a water balance (precipitation, evapotranspiration, surface water run off, surface and ground water interaction, subsurface storage and run off) has to be established. One of the key factors could be the water storage in sub soil. The idea of water banking will be introduced. This supports the awareness that water has a value and optimisation may have cost involved. Cost is not necessarily seen in a monetary sense, but also in providing labour hours and commitment to maintain infrastructures. Taking the above into consideration and ensuring a participatory approach at all levels and between all stakeholders and partners will lead to a sustainable production system. By taking environmental requirements and impacts into account at an early stage environmental services are becoming an appropriate value.
Objectives: The study links East African and European re-searchers into strategic alliances so as to contribute to resolving conflicts prevailing between the needs of different forest stakeholders and the need to sustain the remaining forest and its biodiversity. The project will develop a scientific basis and directly applicable tools for forest ecosystem restoration and sustainable management. The particular objectives are to: - Establish and validate ecological & socio-economic criteria against which status and pro-cesses of forest and its management can be assessed - Assess indicators that permit inference of the status of a particular criterion and to formulate appropriate verifiers - Design and validate nature-based silvicultural tools to gear operations so as to improve local livelihoods and sustain forest resources - Integrate results into appropriate technology packages and disseminate to target-groups. Activities: Establishment of country-specific tandems of local and European institutions. Identification of locally applicable C&I for sustainable forest management and standardisation of research methods. Together with stakeholders, joint development of a framework in which C&I can be verified locally, based on prevailing information and complementary research. Participating NGOs to facilitate establishment of socio-economic context, research institutions to investigate status and dynamics of forests. In parallel, research will commence on silviculturally relevant ecosystem characteristics. Mid-project evaluation of descriptive-analytical 1st project phase so as to formulate the experimental, predictive 2nd phase of the study. Definition of research approaches to calibrate verifiers for indicators and to test silvicultural tools suited to guide the forest ecosystem into the desired direction or status. Research on the management of invasive species, natural establishment of desirable species and on stand improvement treatments. The continuous input and evaluation through an NGO moderator will help to fine-tune and ensure the client-orientated approach of the silvicultural research. A specific communication module serves to translate scientific findings into technological packages relevant to stakeholders. Expected Outcome: Regional framework to assess sustainability of forest management. Silvicultural tools for forest restoration and sustainable forest management. Research findings translated into formats appropriate to the target group, including extension, policy advice and management guidelines.
Ziel des von der AiF geförderten Projektes ist es, einen Leitfaden zur Entscheidungs- und Planungshilfe für den wirtschaftlichen Einsatz von Mikro-Gasturbinen in kmU zu erstellen. Diese herstellerneutrale Analyse soll den kmU diese neue Technologie nahe bringen und ihnen eine Untersuchung der Einsatz- und Nutzungsmöglichkeiten im eigenen Unternehmen ermöglichen. Im Rahmen des Projektes werden zum einen umfangreiche Messungen an einer Mikro-Gasturbine durchgeführt, um detaillierte Kenntnisse über das Betriebsverhalten zu erhalten. Zu diesem Zweck hat das IUTA eine Mikro-Gasturbine erworben und in ihr eigenes Energieversorgungsnetz integriert. Hier wird die neue Technologie vor allem zur Bereitstellung von Prozesswärme über Thermoöl eingesetzt, womit sie die erste in Deutschland installierte Mikro-Gasturbine zur Prozesswärmeerzeugung ist. Zum anderen wird die Mikro-Gasturbine theoretisch analysiert. Hier werden einerseits Studien durchgeführt, welche möglichen Einsatzbereiche zur Prozesswärmeerzeugung in der Praxis gegeben sind, wobei neben thermodynamischen Untersuchungen insbesondere Wirtschaftlichkeitsanalysen im Vordergrund stehen. Zudem wird bei den theoretischen Untersuchungen die Frage geklärt ob der Einsatz von Mikro-Gastubinen mit variablem Rekuperator-Bypass, zur Anpassung an den Wärmebedarf, gegenüber dem Einsatz mit voller Rekuperation und nachgeschalteter Zufeuerung sinnvoll ist.

Objective: The primary aim of the SIINN ERA-NET is to promote the rapid transfer of the results of nano-science and nanotechnology (N&N) research into industrial application by helping to create reliable conditions. In order to strengthen the European Research Area and to coordinate N&N-related R&D work, the project has the aim of bringing together a broad network of ministries, funding agencies, academic and industrial institutions to create a sustainable transnational programme of joint R&D in N&N. The commercial application of nano-materials (NMs) products is increasing rapidly, but one important question, the safety of NMs, still represents a barrier to their wide innovative use. Therefore the first priority of SIINN is to focus on developing a consolidated framework to address nano-related risks and the management of these risks for humans and the environment by investigating the toxicological behaviour of NMs. European R&D activities in N&N remain largely uncoordinated and fragmented, resulting in the sub-optimal use of available resources, such as human resources, research equipment and funding. Since available data on their toxicological behaviour is often scant, unreliable or contradictory, the SIINN Project will focus on ways of remedying this situation. After defining the criteria important for NM toxicology, the environmental health and safety (EHS) information currently available to Europe will be examined. Liaisons will strategically be established and maintained. They will network with organisations looking into the EHS of NMs within Europe and abroad with the aim of continually exchanging information with these. Available information will be examined for their reliability in respect of the assessment of the risks of NMs towards human health and to the environment and major knowledge gaps identified. At least two joint, transnational calls will be organised during the initial lifetime of SIINN in order to fill these gaps.
In spite of a variety of efforts, tropical forests are still threatened by exploitation and conversion to agricultural land-use. Besides legal protection, sustainable management concepts are essential for stable conservation of these ecosystems. This project aims at identifying and optimizing the potentials for forest management for three different ecosystems (Dry Forest, Tropical Mountain Rain Forest, Paramo) along a height- and climate gradient in Southern Ecuador. Therefore, multiple and locally differentiated aspects of forest management have to be considered: the direct provision of goods (timber and non-timber forest products) as well as ecosystem services (carbon sequestration, water regulation), which are of increasing importance; moreover, the effects of forest management on biodiversity and the impacts of climate change on resilience indicators and the potential distribution of selected species with high potential for sustainable management or conservation should be investigated. First of all, the most important forest structure types and possible improvements of management alternatives have to be identified at the three sites for the assessment of different management concepts. The alternatives will be tested on experimental field plots and consequently monitored for their impacts on the locally most important criteria of forest management. A sound decision support tool will be developed, taking into account uncertainties with regard to input parameters and the relevance of different criteria of forest management. Therefore, Multi Criteria Decision Analysis will be used to generate locally adapted management concepts for the different ecosystems. Those concepts should be able to consider the multiple functions of forest management and will represent the forestry component in sustainable land-use models. The comprehensive studies will be carried out in close cooperation with other scientific teams from Germany and Ecuador as well as local institutions of relevance for forest management. The direct involvement of Ecuadorian students and young academics and the integration of the investigations in educational concepts will contribute to capacity building and local efforts for the enhancement of environmental competencies. Moreover, the experimental field plots will serve in parts as demonstration objects for the implementation of sustainable forest management concepts.
Due to ecological reasons and because of the need to remain independent from foreign energy suppliers, the power generation in offshore wind parks becomes more and more important in Germany. It is therefore planned to build up approximately 1,300 new offshore wind power plants with a capacity of 6,500 MW near the German coastline until 2020. The structures are installed on the ground of the sea in a water depth that might in some cases reach 50 m. The mechanical loading situation for these structures is characterised by an enormous weight combined with high cyclic stresses resulting from the service loads and the tide. Hence, hot rolled steels with a yield strength of 355 MPa are employed in a maximum thickness of 100 mm. Until now, the required toughness properties for these structural steels and their welds are 40 J at -20 C. However, in a plate thickness of 100 mm, only the submerged arc welding (SAW) process can be used to guarantee such toughness properties, but especially in these heavy plates, submerged arc welding is rather time consuming and consequently more uneconomic compared to other welding techniques. Due to these disadvantages, it can even be expected that only part of the planned power plants will be built up in time as the high welding time of several hours per m causes too many delays. From the point of structural integrity, it can be argued wether a Charpy impact toughness of 40 J is really required, as this criterion is only set based on experiences of mechanical and civil engineers. Thus, it can be concluded that different welding techniques should be regarded as alternatives to SAW in case that the 'real' toughness requirements are less than 40 J at -20 C. Electron beam welding would be a favourable welding process for such heavy plates as even 100 m thick plates can be welded in one single step, but until now the toughness requirements of 40 J have not yet been met. It is therefore the aim of the research project to reinforce the electron beam welding process for the application to heavy plates in offshore wind power plants. To reach this aim, the following tasks are be carried out: - improvement of the electron beam welding process in order to achieve better toughness properties of the welds, - application of reliable fracture mechanics concepts in order to calculate realisitc toughness requirements. With regard to the process, already a this stage of the project an enormous improvement of the toughness properties of EB weld seams could be demonstrated based on optimisation of the welding process. Furthermore, it could be shown that by establishing the leakage before breakage criterion combined with regular inspections, the toughness requirements can be significantly reduced. Thus, the EB welding can be applied to offshore wind energy installations even if steels of higher yield strength (e.g. S460Q) are selected.
