Water, energy and resources play a role in almost every company - either in the products and services offered and/or in the operation of the company. As part of this project, projects were carried out with small and medium-sized enterprises (SMEs) - tailored to the needs of the respective company and ideally with networking - both professionally, technologically and entrepreneurially. The aim was primarily to develop and transfer green technologies.
The aim was to enable the companies to strengthen and expand their market position with the knowledge and expertise they had acquired. Depending on the area, it was both a challenge and an opportunity for the companies to continue to develop unique selling points and increase efficiency and flexibility in order to maintain and expand their competitiveness. The promotion of technology transfer between universities and SMEs was intended to achieve the application-orientated implementation of research results and better networking between science and industry.
Information on the individual projects can be found on the respective project pages.
As part of the "Green Technology Workshop Hof", this project worked on a solution to tackle the increasing scarcity of water in large parts of the world. Wastewater disinfection for subsequent reuse as process water played a key role in this. Together with Hydrotec GmbH, iwe investigated possibilities for wastewater treatment using UV LEDs.
Due to a lack of exhaust air purification in the past, flame lamination increasingly fell into disrepute and was replaced by supposedly cleaner processes, such as lamination using an engraving roller or flatbed press lamination. As part of this project - as part of the "Green Technology Workshop Hof" - the CO2 balances for all three lamination processes were drawn up together with the company Hofer Textilveredelungs GmbH, compared with each other and optimisation potential was determined.
The aim of this project, with the support of Genes Kältetechnik GmbH, was to develop an ice battery concept for cooling applications that stores surplus energy from solar PV during the day and uses it at night to cover cooling requirements when solar PV electricity is not available. A laboratory test rig with a water storage tank and heat exchangers was set up at the Münchberg campus in order to work in operating scenarios that are as close to the application as possible.
In co-operation with Völkl Motorentechnik GmbH, the EEuropean Fonds for regional EIn a project funded by the European Regional Development Fund (ERDF), a gas treatment option was developed to utilise heavily contaminated pyrolysis gases from biochar production for energy generation.
The partner company InnoQuer and the Institute for Water and Energy Management (iwe) jointly developed a refrigerator that works without electricity. The aim was to produce a low-cost, environmentally friendly, low-energy refrigerator from regionally available materials. The target group was private households in Cape Verde. However, the model can be further adapted so that it can also be used in other off-grid regions.
As part of the "Green Technology Workshop Hof", the Institute for Information Systems at Hof University of Applied Sciences (iisys) developed a monitoring app for smart homes together with Gemeinhardt AG as a project partner. For owners of a photovoltaic system, it was not possible to monitor the energy flows of the system in a meaningful way if the individual components came from different manufacturers. The aim of the project was to create an app that can display manufacturer-independent energy data and visualise energy flows.
A professional energy management system was developed in a co-operation project as part of the "Green Technology Workshop Hof" in order to improve the existing operating concept of the Stadtsteinach outdoor pool. The basic structure of the newly planned concept was a combined system of photovoltaics and air-water heat pumps. Existing components were integrated into the new energy concept and new elements were planned for optimisation. The aim was to make the outdoor pool, including all associated buildings, as energy self-sufficient as possible.
The aim of the project was to develop a technical option to enable additional added value for traditional, regional fish farming. Until now, the process water used in fish farming was generally untreated or returned to the ecosystem after passing through a sedimentation tank. Substances contained in the process water, such as nitrogen and phosphorus compounds, remained unutilised. Opportunities for interaction with other aquaculture systems were not utilised. As part of the "Green Technology Workshop Hof", new approaches were created to utilise the residual materials and coupling possibilities efficiently.
As part of the "Green Technology Workshop Hof" project, existing filter technology was optimised to enable the reuse of purified wastewater as process water. The project was realised together with utp GmbH.
As part of the "Green Technology Workshop Hof", expert interviews were conducted in this research project to determine the requirements for a digital platform for sewage sludge disposal and utilisation in Bavaria in order for it to be used by Bavarian municipalities.
The waters from Nuremberg to Munich are the most heavily used surface waters in the whole of Bavaria. In order to bring about a long-term positive development in terms of environmental protection, strategic goals should be implemented on the basis of the Water Framework Directive 2020. This research project was carried out as part of the "Green Technology Workshop Hof" together with AIR Rietzler GmbH.
The almost complete elimination of microplastics from wastewater is one of the most crucial challenges facing wastewater treatment plant operations today. In this project, as part of the "Green Technology Workshop Hof", the iwe, together with TSH GmbH, focussed on the efficiency of biodegradable flocculants in sewage sludge dewatering plants.
The aim of the project, as part of the "Green Technology Workshop Hof", was to develop an optimised injection-moulded plastic carrier plate for pneumatic tube systems to save fossil raw materials and thus reduce costs. Hof University of Applied Sciences worked together with Hörtig Rohrpost GmbH on this project. The company provided the necessary data and carried out a series of tests, while the university offered design proposals and optimisation approaches based on numerical calculations.
As part of the "Green Technology Workshop Hof", the university worked together with the company Ahlborn on a system for transferring physical, electrical or chemical measurement data to the LabView system development software. Previously, it was not possible to transfer data between the systems. The interface generation enabled measured values to be displayed, mathematically processed, saved, printed and exported for further processing. In addition, the combination of the Ahlborn measuring system and the LabView software opened up a new user group for Ahlborn.
The energy management of a brewing process is complex, as different forms of energy are required. The economic operation of such plants requires an optimised design and adjustment of the process. In collaboration with Familienbrauerei Georg Meinel GmbH, the potential for optimising the energy efficiency of the production processes involved was investigated. The aim was to combine the individual processes efficiently.
In this project, which was implemented as part of the "Green Technology Workshop Hof", the iwe dealt with the optimisation of thermal storage. Specifically, data on stratified storage systems was collected and evaluated using simulation techniques and optimisation potential was identified. This project was carried out together with the company Juratherm.
As part of the "Green Technology Workshop Hof", the Institute for Biopolymers at Hof University of Applied Sciences (ibp) investigated ways of recycling industrial waste products - in this case glass panes from cars - in this research project. The aim was to feed the glass panes into a recycling process through special treatment and further processing techniques.
Every year, Europe produces many tonnes of unused residual and waste materials from agriculture.
The extent to which these materials have the potential to be used for further processing into paper, cardboard or composites was determined in this project. This project was realised as part of the "Green Technology Workshop Hof".
The project was realised as part of the "Green Technology Workshop Hof" by the EEuropean Fonds for regional Edevelopment programme (ERDF). The development prospects of an old industrial site, the Winterling site in Schwarzenbach an der Saale, were determined. Among other things, a new energy concept was developed that provides for the use of renewable raw materials. The aim of the co-operation between the Fickenscher architects' office and the university was to convert the building's basement rooms into heat storage units and to identify further possibilities for the use of storage systems.
This "Green Technology Workshop Hof" project was looking for a practicable solution for local authority water managers to document proof of control in the drinking water supply. Until now, there was virtually no simple and uncomplicated solution. Together with Mösslein GmbH, an app was developed that can be used as a digital maintenance and management tool.
Wood gas is already being used to efficiently generate electricity and heat from wood. As part of the "Green Technology Workshop Hof", the research work in this project focused on tapping into new fuel potential for this process and developing ways to optimise the process. The iwe was supported by ReGaWatt GmbH in carrying out the tests.
The research here is tough.
