Integration of Bio-based Insulation Materials as a Contribution to the Biological Transformation of Production Technology

Abstract

In the context of a circular economy, the adoption of biological principles and materials play a decisive role in the transformation to a more sustainable production technology. Ecologically harmful materials such as polystyrene (so-called Styrofoam), for example, has properties for thermal and acoustic isolation. This material has therefore been used in production machinery to control thermal issues and improve product quality. Here, the use of renewable and biodegradable materials can ensure these measures have a minimal environmental footprint while maintaining the intended functionality.This paper serves to open-up opportunities and define requirements for the integration of bio-based isolation materials in production machines. For both thermal and acoustic issues, the place of implementation and the choice of insulation material, as well as its shape and composition, determine the ability to isolate over the required temperature range. In addition, coatings and surface functionalization offer possibilities for using bio-based materials even under demanding process conditions. Concluding, the experimental approach on the effectiveness of bio-based insulation materials within a machine tool is presented. The technologies presented in this work have been developed by the participating Fraunhofer institutes.
