Biocellfilt2

Project start: January 2023

End of project: December 2024.

The main objective of this project is the development of high-performance, biosourced ((ligno)cellulose fibers) air filtration systems with multiple circularity possibilities. The strategies implemented to increase the performance of these cellulose filters will have the additional advantage of providing antimicrobial properties to them.

The targeted applications will range from indoor air filtration systems (homes, Horeca, hospitals, industries, etc.) to facial masks and
surgical where the recyclable and biodegradable side of the proposed solution will make it possible to considerably reduce the impressive volumes of waste destined for incinerators or unfortunately ending up in nature in the long term.

Optimizations/modifications of the properties of these air filters will be carried out both by chemical means and by plasma

At the end of the project, the feasibility of the recycling route will be assessed and will include in particular the production of insulation panels based on
cellulose where the molecules added to provide antimicrobial properties during the first life will serve as antifungal agents during this second life.

The final deliverable of the research is a biosourced filter media, based on modified (ligno)cellulosic fibers, biodegradable, efficient, less sensitive to changes in humidity level, possessing antimicrobial properties and multiple circularity possibilities. This filter media can be integrated into indoor air filtration systems (homes, Horeca, hospitals, industries, etc.) and into facial and surgical masks.
