Herein, the production of 5-hydroxymethylfurural (5-HMF) from fructose in in a liquid-liquidtubular reactor is proposed. In this intensified reactor in-situ extraction of 5-HMF into a disperse phase consisting of the solvent 2- methyltetrahydrofuran (2-MTHF) is performed. The disperse phase is contacted in a countercurrent flow relative to the continuous phase in which 5-HMF is produced. The design of this novel reactor concept follows a model-based approach. Based on a newly parameterized equation of state, the phase equilibrium of the ternary system 2-MTHF/water/5-HMF as a function of composition and temperature is described. Root mean square deviations for the thermodynamic model compared to experimental data are below 0.02 mol mol−1. From this accurate description of phase equilibria, the transport variables density and viscosity are calculated for both liquid phases within the range of experimental error. The acid-catalyzed dehydration of FRC to 5-HMF is described by a newly developed kinetic model. This kinetic model enables calculation of the temporal change in concentration caused by reaction and mass transport into the organic phase. Sedimentation and mass transport into the disperse phase are investigated in single-drop experiments. Based on these experimental data, parameters for the mathematical description of sedimentation and mass transfer are obtained. The results of the models developed in this work allow a calculation of sedimentation velocities with an accuracy greater than 0.015mms−1. Single-drop mass transfer calculations exceed an overall accuracy of 4%. The herein developed rate model for the description of local and temporal concentration profiles in the liquid-liquid tubular reactor allows a quick evaluation of the potential of this design. Due to the efficient extraction in the countercurrent mode of operation, the 5-HMF yield compared to batch results is increased by 16% at full conversion. Additionally, a validation experiment was carried out in a custom-made pilot plant. A comparison of experimental results and results of the reactor modeling for this validation experiment yields an accuracy greater than 80 %. An extrapolation of the model data to the stationary point of operation shows thata 5-HMF selectivity of 93% at 30% fructose conversion is achieved. The performance of the two-phase 5-HMF synthesis in the liquid-liquid tubular reactor developed in this work thus offers clear advantages compared to operation in a batch reactor.

Phenoxypropanols have been used for some time as ingredients in surface and instrument disinfectants. Since the residual solutions of these preparations are discharged into the waste-water, the biodegradability of the ingredients used is of great importance. Tests by means of the Zahn-Wellens test in accordance with OECD guidelines have shown that phenoxypropanols are biodegradable. In further studies it was investigated whether unwanted intermediate products are formed in considerable amounts. Of particular interest was the question of the possible development of phenol outside the bacterial cells. To test the biodegradability of the aromatic alcohols and to ascertain whether there is extracellular formation of phenol, microorganisms were isolated from the municipal sewage plant at Stellinger Moor, Hamburg, and from water from the River Elbe. Phenoxypropanol-containing solutions were then inoculated with the bacteria and incubated at 30 degrees C. At regular intervals both the concentration of the alcohols was determined and the test for phenol was performed by means of liquid chromatography on reverse phase material (RP 18) and detection with a photodiode array detector. The breakdown of the phenoxypropanols was monitored for a period of up to 4 weeks. During this period a clear breakdown of the aromatic alcohols was observed. No phenol was detected.

Climate change will affect the agricultural ecosystem on different levels. It also alters interactions of weeds and crops. Each weed reacts on an individual basis to changes. Weeds can show an increase or decrease in abundance, can invade new areas or can completely vanish. They also can change traits to be more competitive. Overall, this will result in a different abundance and composition of weeds, as well as a different damaging potential. Land-use changes and agricultural adoption strategies to climate change will have dramatic influence on the interactions as well. Based on these interactions, there will be various options for dealing with climate change.

Natürliche Auengebiete sind durch eine heterogene Habitatstruktur und eine ausgeglichene Verteilung gekennzeichnet, welche eine hohe Bio- und Prozessdiversität ermöglichen. Nehmen die Abflussmenge und -dynamik in einem Fliessgewässer ab und fehlt der Geschiebenachschub, wie es beim Bau eines Staudamms oft der Fall ist, kann auch der ökologische Wert der Aue durch den qualitativen oder quantitativen Verlust von Lebensräumen für Pflanzen und Tiere sinken. In der vorliegenden Bachelorarbeit wurden die raum-zeitlichen Entwicklungen der Habitate an der Restwasserstrecke der Sarine unterhalb des Rossens Staudamms (Kt. FR) ausgehend von ihrem natürlichen Zustand im Jahr 1943 bis 2013 sowie an einer naturnahen Referenzstrecke der Sense (Kt. FR/BE) anhand von historischen Luftbildern rekonstruiert. Diese wurden in GIS digitalisiert und die Habitate einer von acht Klassen zugeordnet. Anschliessend wurden die relativen Habitatanteile, die Habitatänderungsraten (Habitat turnover) sowie ökomorphologische Indikatoren zur Erfassung der Komplexität und Veränderungen des Auensystems bestimmt. Natural floodplains are characterized by a heterogeneous habitat structure and a balanced distribution, which enable a high bio- and process diversity. If the flow rate and dynamics are decreasing in a river, and bed load is lacking, the ecological value of the floodplain can be reduced by the qualitative or quantitative loss of habitats for plants and animals. In this bachelor thesis, the spatial and temporal developments of the habitats on the Sarine watercourse below the Rossens dam (Kt. FR) were examined from their natural state in 1943 until 2013 as well as on a near-natural reference stretch of the Sense (Kt. FR/BE) based on historical aerial images. They were digitized in GIS and the habitats were assigned to one of eight classes. Subsequently, the relative habitat portions, habitat turnover and ecomorphological indicators were used to determine the complexity and changes of the floodplain system.

Der Klimawandel erfordert den Ausbau urbaner blau-grüner Infrastrukturen, was jedoch mit einem erheblichen Mehrbedarf an Wasser einhergeht. Zentrale Abwasserinfrastrukturen genügen nicht den Ansprüchen der Ressourceneffizienz und Nachhaltigkeit. Daher ist ein neuer Umgang mit Wasser im städtischen Kontext notwendig. Die getrennte Erfassung von schwach belastetem Grauwasser aus Duschen und Handwaschbecken bietet eine nahezu kontinuierliche, wenig verschmutzte Wasserressource zur Wiederverwendung. Naturnahe Verfahren wie Bodenfilter können zur Grauwasseraufbereitung eingesetzt werden; der hohe Flächenbedarf beschränkte jedoch bisher den Einsatz in dicht besiedelten Gebieten. In dieser Arbeit werden technologiebasierte und konzeptionelle Ansätze vorgestellt. Dabei wurden acht vertikal durchströmte Bodenfilter zur nutzungsorientierten Grauwasseraufbereitung im kleintechnischen und Pilotmaßstab untersucht und zusätzlich ein Excel-basiertes Instrument entwickelt, das die Auswirkungen der Grauwasserseparation auf konventionelle zentrale Kläranlagen bewertet. Die Ergebnisse zeigen schwankende Zusammensetzungen und Mengen von Grauwasser. Aufgrund begrenzter Datenverfügbarkeit in der Fachliteratur wird empfohlen, die hier ermittelten 85-Perzentilwerte von 13 g CSB (chemischer Sauerstoffbedarf) pro Einwohner (E) und Tag sowie 55 L/(E·d) für die Bemessung von Anlagen zur Behandlung von gesiebtem, schwach belastetem Grauwasser heranzuziehen. Die ermittelten Stickstofffrachten und -konzentrationen waren aufgrund von Urinkontamination um 60 – 130 % höher als bisher angenommen, während die Phosphorkonzentrationen gesetzlich bedingt um ca. 60 % niedriger lagen. Alle Vertikalfilter wiesen im Ablauf meist < 2,0 mg/l abfiltrierbare Stoffe (AFS) bzw. < 10 mg/l CSB auf (also Eliminationen von überwiegend > 98 % AFS bzw. > 97 % CSB). Der aufgeständerte Rheinsandfilter zeigte bei < 12°C eine eingeschränkte Nitrifikation, während der Lavasandfilter bei > 5°C vollständig nitrifizierte. Die Vertikalfilter entfernten bis zu 50 – 70 % Stickstoff bei Drainageeinstau und Nitratrückführung. Der Lavasandfilter hielt Phosphor weitestgehend zurück. Die Reduktion von Escherichia coli, Enterokokken und Gesamtcoliformen betrug > 3 log-Stufen, während organische Spurenstoffe meist zu > 85 % entfernt wurden. Durch gezielte Anpassungen im Aufbau und Betrieb wurden für verschiedene Nutzungszwecke (Bewässerung, Versickerung und Toilettenspülung) geeignete Qualitäten erreicht. Der erforderliche Flächenbedarf für Bodenfilter zur Behandlung von schwach belastetem Grauwasser wurde zu 0,4 m2/E bestimmt (bezogen auf 85-Perzentilwerte). Dem liegen eine CSB-Flächenbelastung von 32 g/(m2·d) und eine hydraulische Flächenbelastung von 130 L/(m2·d) zugrunde. Die Anwendung von Lavasandfiltern in aufgeständerter Bauweise erwies sich als praxistauglich. Damit wird die Ausweitung des Bodenfilterverfahrens auf den urbanen Raum gefördert. Die Bilanzierungen zeigen, dass die Abtrennung von bis zu 17 % des an die Kläranlage angeschlossenen Grauwassers förderlich für den Kläranlagenbetrieb ist. Bei höheren Abtrennungsraten könnte jedoch eine Stickstoffrückgewinnung/-entfernung aus stickstoffreichen Schlammströmen erforderlich werden. Die Trennung bzw. dezentrale Aufbereitung von Grauwasser hat Vorteile wie Verdunstungskühlung und Wasserwiederverwendung und unterstützt zentral die Transition zu ressourcenorientierten Sanitärsystemen. Insgesamt können betrieblich und baulich angepasste Bodenfilter eine wichtige Rolle in dieser Umstellung spielen und einen deutlichen Beitrag zum nachhaltigen Umgang mit Wasser im städtischen Bereich leisten. Climate change requires the strengthening of urban blue-green infrastructure, which, however, is associated with a significant increase in water demand. Concurrently, centralized wastewater infrastructures are inadequate to meet the criteria for resource efficiency and sustainability, as mixed wastewater discharge persists. Therefore, a new approach to water management is imperative in urban contexts. Source-separation of light greywater, such as from showers and hand wash basins, provides a nearly permanent, low-polluted water resource for reuse. Nature-based solutions like constructed wetlands can be employed for greywater treatment; however, the substantial area requirements have so far limited their implementation in highly urbanized areas. This study presents technology-based and conceptual approaches, involving the investigation of eight vertical-flow constructed wetlands for on-demand greywater treatment at small and pilot scales. Additionally, an Excel-based tool was developed to assess the impact of greywater separation on the operation of conventional wastewater treatment plants (WWTP). The findings reveal varying compositions and volumes of the investigated greywater. Due to limited data availability in existing literature, it is recommended to utilize the 85th percentiles derived from this study for the design of constructed wetlands treating light greywater, amounting to 13 g COD (chemical oxygen demand) per person (P) and day and 55 L/(P·d). Total nitrogen loads and concentrations were 60 – 130% higher than previously assumed due to urine contamination, while total phosphorus concentrations were about 60% lower due to legal regulations. In all wetland systems investigated, the effluent showed < 2.0 mg/L of total suspended solids and < 10 mg/L of COD, corresponding to eliminations mostly > 98% and > 97%, respectively. The elevated Rhine sand wetland showed limited nitrification at < 12°C, while the lava sand wetland showed complete nitrification at > 5°C. The investigated wetlands removed up to 50 – 70% of nitrogen by impounding the drainage layer and returning nitrate-rich effluent to the wetland surface. The lava sand wetland retained phosphorus extensively. Reduction of Escherichia coli, Enterococci, and total coliforms exceeded > 3 log levels, while organic micropollutants were predominantly removed by > 85%. Through adjustments in design and operation, suitable qualities were achieved for different reuses (irrigation, infiltration, and toilet flushing). The necessary surface area requirement for constructed wetlands treating light greywater was determined to be 0.4 m²/P (based on 85th percentile values). This value is derived from a COD surface load of 32 g/(m²·d) and a hydraulic surface load of 130 L/(m²·d). The deployment of elevated lava sand wetlands proved to be viable in practice. Overall, these findings promote the expansion of constructed wetlands to urbanized areas. Mass and volume flow balances indicate that the separation of up to 17% of the greywater connected to the WWTP benefits its operation. However, at higher separation rates, TN recovery/removal from nitrogen-rich sludge streams may be required. The separation/decentralized treatment of greywater offers manifold advantages such as evaporation cooling and water reuse, and significantly supports the transition towards resource-oriented sanitation systems. Adapted constructed wetlands can play an important role in this transformation process and can significantly contribute to a more sustainable water management in urban areas.

Auenlandschaften gehören zu den weltweit am meisten gefährdeten Ökosystemen. In der Schweiz sind bis heute schätzungsweise mehr als 70% aller Auenlandschaften verschwunden und von den noch vorhandenen befinden sich nur noch wenige in naturnahem Zustand. Mehr als die Hälfte des in der Schweiz produzierten Stromes stammt aus der Wasserkraft und wiederum ca. 57% dieses Stromes stammt aus Speicherkraftwerken, bei welchen in Zeiten der erhöhten Stromproduktion Pegel- und Abflussschwankungen auftreten können, die als Schwall-Sunk bezeichnet werden. Durch das veränderte Abfluss- und Geschieberegime können zeitlich und räumlich instabile Lebensräume entstehen und wichtige Auenhabitate vom Fliessgewässer abgetrennt werden. Im Rahmen dieser Bachelorarbeit wurde die morphologischen Veränderungen der wichtigsten Auenhabitate in der Schwall-Sunk-Strecke der Sarine/Saane nach dem Bau des Rossens-Staudamms (Kt. FR) mittels einer Auswertung von historischen Luftbildern untersucht. Als naturnahe Referenz diente die Senseaue bei Plaffeien (Kt. FR). Floodplains are among the world’s most vulnerable ecosystems. In Switzerland, it is estimated that more than 70% of all floodplains have disappeared, and only a few are left in the natural state. More than half of the electricity produced in Switzerland comes from hydroelectric power, and again about 57% of this electricity comes from storage power plants, where fluctuations in the level occur in times of increased power generation. Due to the altered run-off regime, very unstable habitats are created in time and space, and lateral cross-linking decreases, which means that important floodplain habitats are seperated from the river. Within the scope of this Bachelor thesis, the morphological changes of most important floddplain sites in the hydropeaking stretch of the Sarine/Saane were investigated by means of an evaluation of historical aerial images after the construction of the Rossens dam (Kt. FR). The Sense floodplain served as a near-natural reference at Plaffeien (Kt. FR).

Plant protection products are a significant component of conventional arable farming in Germany. They have helped increase land productivity and reduce yield losses, thereby providing a significant contribution to food security. However, plant protection products have negative impacts on biodi-versity. Moreover, their degradation products can be found in ground and surface waters, and they are associated with negative effects on human health. Against this background, the aim of policy is to reduce the use of plant protection products and the associated risks. By contrast, the questions of whether and how farms can adapt their production systems and the resulting costs remain largely unanswered. Similarly, although the advantages and disadvantages of different policy implementation strategies for reducing plant protection products are discussed at both the European and national levels, the scientific publications are aimed primarily at intro-ducing a tax model. A concrete comparison of different policy measures and an assessment of the adaptation reactions as well as the associated consequences, taking agricultural expertise into ac-count, usually is not carried out. Against this background, based on a typical farm in the soil-climate region “Südhannover” and us-ing a focus group approach with farmers and advisors, the present dissertation investigated which farm adaptation measures can reduce the risks to humans and the environment associated with the use of plant protection products by 25 % or 50 % and what adaptation costs result from such measures. The risks posed by pesticides were determined with the help of the Pesticide Load Indi-cator (PLI). In order to be able to quantify the yield effects as a result of reduced pesticide use, regional and national trial evaluations were consulted. In addition, the expected yield effects were differentiated between a best and worst case and a “normal year”. In order to reduce the PLI by 25 %, farmers first will substitute less toxic active substances for those with a higher PLI. Similarly, weeds are increasingly regulated mechanically and non-selective herb-icides are replaced by mechanical tillage before summer crops. If no crop-specific PLI reduction is required and alternative crops are available, farmers will substitute crops with a low net margin per PLI unit used (e.g. rape with grain maize). If the PLI is halved, reduced fungicide and insecticide use across crops or later sowing dates in cereals also are suitable for reducing the risks from plant protection products. With a crop-specific PLI reduction of 25 %, changes in the net margin range from + 25 €/ha for sugar beet to – 60 €/ha for stubble wheat can be expected. If the PLI has to be reduced by 50 % for each individual crop, the range of adjustment costs among the crops increases further. While the PLI can be halved for oilseed rape with costs of about 50 €/ha, the net margin for stubble wheat or winter wheat after silage maize decreases by about 150 €/ha. At farm level, the results show that the more adaptation flexibility farmers are granted, the lower the adaptation costs. With a 25 % reduction of the PLI and taking into account the active ingredient substitution, manageable adaptation costs of between about 10 €/ha and 20 €/ha can be expected, depending on the adaptation flexibility granted. The change in grain units (GU) produced varies between + 4 % and – 5 %. On the other hand, the adjustment costs increase disproportionately strongly with a PLI reduction of 50 %, so that an operational net margin reduction of between about 80 €/ha and a maximum of 125 €/ha can be expected. With a PLI reduction of 50 %, the change in GU produced is between 0 and a maximum of -7 %. As farmers are in competition with their colleagues on the land and tenancy markets, they usually cannot afford to voluntarily switch to production systems that cause lower yields or cost increases and thus put them at a competitive disadvantage vis-à-vis neighbouring farms. Policymakers there-fore must change the framework conditions for all farms in such a way that the adaptation of pro-duction systems is either mandatory or economically viable. A wide range of policy measures are available for this purpose. Following on from the results of the adaptation costs, it therefore was examined how policymakers can use the "PLI" starting point to achieve their reduction target. In order to expose the selected policy measures and impact assessments to the critical judgement of the focus group, four concrete policy measures were developed that can achieve PLI reduction while addressing different secondary objectives. The measures examined include an individual farm PLI ceiling, a licensing system with tradable use rights, a state subsidy for low PLI hectare values and an increase in crop protection product prices depending on PLI. It was assumed that the policy measures would be introduced throughout the European Union. The effects that can be ex-pected on production, farm incomes and the administrative and control costs for farmers and the state were worked out in an impact assessment. The following results emerged: In the case of a PLI ceiling for individual farms and at the same time for individual crops, every farm must, in principle, reduce its PLI use if it does not yet meet the targets in the initial situation. This leads to an area-wide risk reduction without shifting the production of individual crops to third countries. However, the adjustment flexibility for farmers is comparatively low compared with other policy options. The control is carried out with the help of an online database. In contrast, an increase in plant protection prices depending on the PLI has the advantage of not having to control all farms, but only "bottlenecks" such as traders and manufacturers of plant pro-tection products. A disadvantage is the high negative income effect for the farms (> 220 €/ha) if the PLI is halved. In addition, readjustments of the levy level are to be expected in order to ap-proach the reduction target. If the PLI use rights are distributed in a licensing system depending on acreage, it can be expected that crops with a high net margin per PLI unit used will be cultivated preferentially. On the other hand, crops with a low net margin per PLI unit used will increasingly be pushed out of cultivation. Farm managers can decide on the basis of the market price for the tradable PLI use rights whether to use them themselves on the farm or sell them on the market. As a result, it is to be expected that PLI units will be saved, especially on marginal arable sites where this saving causes only low costs. The PLI units freed up there move primarily to regions where an above-average net margin per PLI unit can be produced. These are classically favourable locations for arable farming. The comparatively high administrative costs required for tradability must be viewed critically. For the state, this additional effort goes hand in hand with the advantage that the reduction target can be targeted precisely. If the state decides to promote low PLI hectare values with a premium, a negative income effect at farm level can be prevented, as the farm only participates if its costs are lower than the premium payment. The acceptance of the policy measure by farmers is high. A major challenge, however, is the controllability, as there are high incentives to undermine the system. DOI:10.3220/REP1678173967000

Increasing maize cultivation and changed cropping practices promote the selection of typical maize weeds that may also profit strongly from climate change. Predicting potential weed problems is of high interest for plant production. Within the project KLIFF, experiments were combined with species distribution modelling for this task in the region of Lower Saxony, Germany. For our study, we modelled ecological and damage niches of nine weed species that are significant and wide spread in maize cropping in a number of European countries. Species distribution models describe the ecological niche of a species, these are the environmental conditions under which a species can maintain a vital population. It is also possible to estimate a damage niche, i.e. the conditions under which a species causes damage in agricultural crops. For this, we combined occurrence data of European national data bases with high resolution climate, soil and land use data. Models were also projected to simulated climate conditions for the time horizon 2070 - 2100 in order to estimate climate change effects. Modelling results indicate favourable conditions for typical maize weed occurrence virtually all over the study region, but only a few species are important in maize cropping. This is in good accordance with the findings of an earlier maize weed monitoring. Reaction to changing climate conditions is species-specific, for some species neutral (E. crus-galli), other species may gain (Polygonum persicaria) or loose (Viola arvensis) large areas of suitable habitats. All species with damage potential under present conditions will remain important in maize cropping, some more species will gain regional importance (Calystegia sepium, Setara viridis).

Die vorliegende Diplomarbeit befasst sich mit dem Thema ein nachhaltiges, ökologisches und ökonomisches Hotel in Antalya zu entwerfen. Das Klima in Antalya tritt im Allgemeinen in das mediterrane Klima ein. Die Sommer sind heiß und trocken, die Winter regnerisch und stürmisch. Da Antalya eine Touristenstadt ist, gibt es hier Unmengen an Hotels, die vorwiegend für Großfamilien mit Kindern sind. Dieser Entwurf ist anders als die „herkömmlichen“ Hotelprojekte, die es in Antalya schon gibt. Das Ziel des Entwurfes ist ein Treibhaus- und/oder Gewächshaushotel mit all seinen nachhaltigen Nutzen entlang der Küste zu schaffen. Neben der nachhaltigen Gebäudestruktur des Öko-Hotels werden viele energiesparenden Maßnahmen eingesetzt. Im Fokus stehen hierbei die Verwendung von natürlichen Baumaterialien in monolithischer Bauweise, unterirdische monolithische Betonzisterne für Trink- oder Nutzwasser zur Bewässerung des Innengartens und ebenso eine Meerwassersolaranlage, die als zusätzliches Trinkwasser fungieren soll. Durch Gebäudeintegrierte Photovoltaik-Module (GiPV) an der Fassade und auf dem Dach des Atriums wird die Sonnenenergie genutzt und in Strom zur Erwärmung des Duschwassers umgewandelt. Ein Gebäude, dass nicht nur nimmt, sondern auch gibt! Gegen die Monotonie im Alltag soll das Öko-Hotel eine abwechslungsreiche und beruhigende Entspannung fördern. Als therapeutische Zwecke wird die Thalasso- und Kneipp-Therapie angewendet. Thalasso ist einfach eine Heilbehandlung am und mit dem Meer, aber mit allem, was dazugehört: Wasser, Algen, Schlick, Wind, Salz und frischer, daher schadstoff- und pollenfreier Meeresluft. Einzigartige, heilende Kräfte für Körper und Seele! This diploma thesis describes the idea of designing a sustainable, ecological and economical hotel in Antalya. The climate in Antalya generally enters the Mediterranean climate. Summers are hot and dry, winters are rainy and stormy. Antalya is a tourist city, there are tons of hotels here, which are mainly for large families with children. This design is different from the „conventional“ hotel projects that already exist in Antalya. The aim of the design is to create a greenhouse and/or glasshouse hotel with all its sustainable benefits along the coast. In addition to the sustainable building structure of the eco hotel, many energy-saving measures are used. The focus here is on the use of natural building materials in monolithic construction, underground monolithic concrete cisterns for drinking water or water for other purposes to irrigate the inner garden and also a seawater solar system, which is intended to serve as additional drinking water. Building-integrated photovoltaic modules (BiPV) on the facade and on the roof of the atrium use solar energy and convert it into electricity to heat the shower water. A building that not only takes, but also gives! Against the monotony of everyday life, the eco-hotel is intended to promote varied and soothing relaxation. Thalasso and Kneipp therapy are used for therapeutic purposes. Thalasso is simply a healing treatment by and with the sea, but with everything that goes with it: water, algae, mud, wind, salt and fresh sea air, which is therefore free of pollutants and pollen. Unique, healing powers for body and soul!
