Food production and the production of energy and recyclables are increasingly competing (plate or tank problems). One of the major challenges for the future is therefore to sustainably meet the growing demand for food, energy and recyclable materials with low consumption of agricultural land, energy and water resources. The sustainable production of proteins (proteins), lipids (fats) and carbohydrates (sugars and polysaccharides) by cyanobacteria, microalgae or plants is of central importance.

Cyanobacteria, for example, harbor an enormous pool of renewable biopharmaceuticals and fine chemicals. However, this potential is hardly tapped since existing production processes are too energy- and resource-intensive.

In contrast, the research project for the first time uses photosynthesizing, drying tolerant biofilms (terrestrial cyanobacteria) for the fog-controlled production of bacterial polysaccharides and dyes. A resource- and energy-efficient process technology is used, which is realized by means of a novel emersen photobioreactor generation (ePBR). The new system solution combines the advantages of green biotechnology with those of white / industrial biotechnology to optimize a more cost-efficient, environmentally friendly production process for biopharmaceuticals and fine chemicals.

The main task of the Environmental Campus Birkenfeld at Trier University of Applied Sciences was the constructive further development of the emersen bioreactors.

Requirements required for the growth of cyanobacteria were systematically investigated by the project group and implemented in the reactor construction for the reactor construction at the Environmental Campus. These include, for example, flow simulations for uniform distribution of the liquid mist in the reactors.

The growth of cyanobacteria is directly dependent on the aerosol supply. In areas with insufficient aerosol supply, growth is not possible or only possible to a limited extent. In order to be able to assess the suitability of different concept variants, knowledge about the behaviour of the aerosol inside the reactor is an essential criterion. The simulation methods were first examined on a simple model and the simulation results were compared with real test results and in a next step transferred to more complex designs.

In further development steps, several concept variants were worked out, converted into prototypes and tested. Additive manufacturing was used in particular to manufacture the prototypes. In cooperation with the project partners, cyanobacteria were tested in various reactor forms and, for example, harvesting processes were investigated.

Remanufacturing (2014-2019)

Resource-efficient production of mechatronic systems through remanufacturing using assistance robots

Remanufacturing

The research project, carried out in cooperation between the Environmental Campus Birkenfeld, SEW-EURODRIVE GmbH & Co KG and the University of Luxembourg, deals with the development of recycling concepts and remanufacturing processes for economical and ecological production using the example of mechatronic drives. When investigating the problem, the processes for non-destructive dismantling in particular turned out to be uneconomical. Attempts to automate the dismantling process failed due to the variance of the product shape or the unpredictable condition of the product. Only non-destructive dismantling offers the advantage of higher-quality product recycling and thus the possibility of economic and ecological remanufacturing

The use of robot assistants is intended to reduce manual work per piece, improve workplace ergonomics and thus reduce dismantling costs. Higher or non-automated activities of added value are left to the worker. With the human-robot cooperation approach, even sub-processes of dismantling that are difficult or impossible to automate can be implemented economically and reliably. The development of the robot assistant focuses on the development of an agent-based control system for human-robot interaction. For this purpose, semantic models of the product structure are developed which describe the structure of the mechatronic drives. The models allow the disassembly to be roughly planned and used by the assistance system as a process flow program. Based on the formal sequence, the assistance system has a context to the situation or task in the current dismantling step and can offer different forms of assistance for this purpose. The human being decides on the type of assistance to be provided on the basis of the product condition and according to his wishes. In order for the cooperation to function effectively, the assistance system must act largely autonomously by independently selecting, parameterizing and executing predefined program modules for the execution of the assistance. For this purpose, the system requires a variety of information, which can also be found in the semantic models.

The work comprises the identification, representation and processing of information in the area (domain) of dismantling as well as the development of software agents that control robot behaviour (i.e. assistance) in a targeted manner on the basis of the information collected. The goal is the development of more powerful robot assistance systems.
