After an event such as a trade fair or a specific event, immense amounts of waste are generated that cannot be avoided due to the nature of the industry. It is often partitions, floors and decorative materials that end up in the container for mixed waste. Materials that make sense in terms of recycling potential, such as wooden components and reusable aluminum profiles, are disposed of as mixed waste due to their structure without optimized resource utilization. Currently, there is an increasing trend towards sustainable and resource-saving concepts. For the implementation of sustainable resource utilization, the recycling of components of temporary structures must also be considered along with the creation and utilization phases. Locally available materials are required, which are recycled after the utilization phase in a sorted and ideally in existing cycles. The DBU project “ Papierlicht” (“Paper Light”), which was successfully completed in 2020, has shown that stable and recyclable structures can be produced using structural winding technology with paper yarns. In this project, building on these results, recyclable exhibition and presentation systems are to be developed as a modular system including a universal utilization concept based on paper yarns. The other materials used should not have a negative impact on the recycling process and should be natural and renewable.
An environmentally relevant goal is the reduction of mixed waste after trade fairs and events: The paper- or nature-based materials used should enable resource-efficient disposal of the trade fair stand. Another goal is to save weight. In particular, lightweight construction can reduce the emissions that occur during the transport of the individual parts. Structural coil elements offer high potential for exploiting constructive lightweight design principles.
