Cost and environmental footprint analysis of scaled bicomponent fibre production using suspensions
The goal of this thesis is to assess the production costs and environmental footprint of a scaled bicomponent fibre production scenario using aqueous polymeric suspensions.
tructures to exploit more efficient processes by providing affordable and sustainable high-quality preforms made from hybrid fibres - even at large scale.
**Motivation**
Antefil is developing a scaled pilot plant using the bicomponent fibre production method established at CMASLab. This process dissolves the polymer for coating of the individual glass filaments, while they are spun. Scaling this solution route involves challenges related to the use and recovery of the solvent to ensure a closed process at scale and limits the selection of polymers which can be processed. To circumvent these issues, CMASLab is developing an alternative coating method based on aqueous suspensions and is interested in investigating its scalability and economic viability.

The goal of this thesis is to assess the production costs and environmental footprint of a scaled bicomponent fibre production scenario using aqueous polymeric suspensions. This work includes modelling of critical cost- and energy-flows within that process itself as well as for the preparation of the suspension. This may include the modelling of physical phenomena present in these processes. For the environmental footprint assessment, common life cycle analysis tools shall be employed. In addition, the process(es) to be modelled shall also be benchmarked against the state-of-the-art of Antefil’s planned fibre production method.
