Important results from the project
The project goal set from the start, to develop a bio-based and biodegradable melt-spun fiber, has been achieved. The project has been able to demonstrate results in the form of a polymer that has been modified to be suitable for melt spinning, with post-treatment and the creation of a demonstrator for cultivation tests. Attempts to scale up the process from laboratory scale to pilot scale have also shown promising results.
Expected long term effects
The long-term effects are expected to primarily lie within the development of the bioeconomy where biobased and biodegradable materials and products can be offered as substitutes for commonly fossil-based products. The focus has been on single-use products which often end up in nature, where good results have been demonstrated in cultivation tests. The result can also serve as a foundation for future projects, where a shift from lab to pilot scale can be made, closer to commercialization.
Approach and implementation
The project has gone from raw material to prototype where virtually the entire value chain has been represented in the consortium. Bio-based and biodegradable polymers have been analyzed and evaluated for melt spinning. In an iterative process materials have been evaluated and spun. Based on the results and in dialogue with the project group a selection of materials has been taken forward. The project result shows a development where a prototype has been evaluated in cultivation tests in Sweden.
