Biobased biopolymers offer advantages not only on the raw materials side but also on the disposal side through certain promising end-of-life (EOL) options. Especially waste disposal with energy recovery has an added benefit, which lies in gaining carbon neutral energy while allowing multiple uses after possible recycling. This is a very sensible and conservation-minded approach to resource efficiency and carbon dioxide reduction because it maximizes the benefits while minimizing the environmental impact.
The aim of the project is to develop and implement solutions for making components for the automotive sector including auto racing, by using bioplastic and biocomposite materials. Bioplastics and biocomposites in this context are defined as fully or partially bio-based but non-reinforced materials as well as composites with bio-based matrix or bio-based reinforcements.
KraussMaffei Berstorff GmbH (KMB) has been showing its continued interest in pushing the needs-oriented development of biopolymer materials for long-life technical applications together with the IfBB at the Hochschule Hannover.
The project aims to determine the relevant extrusion parameters for natural-fibre compounding. Another aim is to examine those influential factors which arise as a result of adding the natural fibres (in this case cellulose fibres). Such factors include, for example, L/D ratio, fibre origin, fibre pre-treatment, or width of distribution.
Biopolymer materials are currently used mainly in the packaging industry. In recent years, however, there has been a growing tendency toward bio-based plastics for long-life applications.
