Establishment of Urban Bio Spaces
Research Field II | Urban Bio Spaces
Based on the scenarios that in the future neither a sufficient food supply can be guaranteed by global trade ("No Trade") nor sufficient arable and grazing land is available for the conventional cultivation of plants and animals for food production ("No Land"), alternatives must be created which allow food to be produced in sufficient quantities irrespective of these factors. One possibility here is the development of urban bio spaces which offer the various organisms optimum conditions for growth and reproduction and thus enable high productivity in a small area. They can be a combination of a large number of different, self-contained individual cells (so-called compartments) which allows them to be adapted to changing basic conditions such as available space, food demand or type of organism. Due to this modular construction, the integration of the bio spaces into an urban environment is possible, in this way previously unused space in public places or on roofs can be effectively used for food production.
Very high demands are put on the properties of the compartments. On the one hand, they must have sufficient mechanical strength (e.g. to enable machine harvesting) and on the other hand, the weight of the units should be as low as possible to simplify handling and not affect the static strength of buildings. Other important properties of the construction materials can be UV stability or transparency, so that sunlight can penetrate into the interior. For this purpose, the Research Division Polymeric Materials and Composites PYCO of the Fraunhofer Institute for Applied Polymer Research IAP in cooperation with their project partners is developing suitable fiber-reinforced materials that offer the potential to combine the required properties. They consist of fibrous materials (such as glass fibers), which ensure high mechanical strength, and plastics (reactive resins), which shape the composites and make them highly resistant to environmental influences. The chemical and physical properties of the reactive resins can be adjusted by the PYCO research division according to the specific requirements.
In order to create ideal growing conditions for the various organisms inside the compartments, it is also necessary to integrate suitable heat and light sources. The optimal conditions are determined by the project partners within the research field Organisms. Appropriate technical devices such as LED modules or heating elements will be integrated into the fiber-reinforced plastics by the PYCO research division.
During the course of food4future, the developed materials and methods will be used to create several of these compartments as demonstrators to investigate the possibilities of cultivation of food-producing organisms in urban environments.
