BestBioPLA: project completion with trade fair appearance

The materials made from renewable raw materials developed in the BestBioPLA project were successfully processed into an automotive component and presented to a wide audience of experts at the K plastics trade fair in Düsseldorf.

Bio-based and biodegradable, this challenge was taken up by the project team with partners from Germany and Brazil under the direction of Fraunhofer IFAM. Regional resources should be processed in such a way that closed material cycles are created. At the end of the project, the results were shown to a large number of trade fair visitors in the form of a manufactured demonstrator component from automotive engineering at the world's largest plastic trade fair, K, in Düsseldorf (GER) from 19 to 26 October 2022. What is special about the results achieved in the project is the completely new development of a bio-based unsaturated polyester plastic, which, in addition to a very high biogenic content, also enables biodegradability under defined conditions at the end of the product's life. Especially in combination with natural fibre reinforcement, e.g. with flax fibres from Europe or sisal fibres from Brazil, promising lightweight materials with exciting properties can be produced efficiently.

In July 2022, the German partners Fraunhofer IFAM and INVENT travelled to Brazil for the final project meeting at  the Universidade Federal da Paraíba in João Pessoa and discussed the results together with the local partners. The visit of the coordinator of the Brazilian sub-project, Prof. Renate Wellen, to the Fraunhofer booth at the K trade fair was a rounding off. After all meetings had to take place virtually in the previous two years due to the COVID-19 pandemic, the exchange on site was all the more valuable and led to many new ideas.
