LUUUP / RESEARCH & MATERIALS
Textile waste.
New materials.
Research-driven approaches to cellulose recycling, sustainable polymers and textile-based material development.
From scientific concepts to tested material prototypes.
WHAT WE WORKED ON
Research, materials and practical development.
LUUUP was established in St. Gallen, Switzerland, to explore new uses for textile waste. Its work brought together cellulose chemistry, polymer and material research, and the experimental development of textile-based products.
Chemical recycling
Solvent-based approaches to cellulose-rich textile waste and the development of biopolymer materials.
Materials & prototypes
Recycled yarns, fabrics, garments and insulation concepts developed through practical trials.
Collaboration
Joint research, externally funded feasibility work and technical exchange with academic and industrial partners.
01 / TEXTILE MATERIALS
Textile waste into tangible prototypes.
A selection of recycled-fibre materials and demonstrator products developed during LUUUP’s project work. These are research and development prototypes, not items currently offered for sale.
Tote bags from recovered textiles
Two material and product demonstrators made using recycled textile fabrics. The different textures illustrate possible finishes and applications.
Yarns and fabrics
Recovered fibres were processed and explored for use in new textile materials.
Jacket prototype
A garment demonstrator showing the material’s use in tailored clothing.
Hoodie prototype
Experimental outerwear produced during textile-material development.
02 / CHEMISTRY & RESEARCH
Investigating cellulose recycling.
The Innosuisse-funded IonCott feasibility study (58181.1 INNO-EE) was carried out with Empa. It investigated solvent-based processing of cellulose-rich textile waste and potential routes towards biopolymer-based materials.

03 / PROJECTS
Selected research and development work.
IonCott
FUNDED FEASIBILITY STUDY
Research with Empa on chemical processing of cellulose-containing textile waste and potential biopolymer materials.
Textile-based insulation
TESTED PROTOTYPES
Development and testing of insulation material using recovered textile fibres, including thermal and fire-related assessments.
Biopolymer composites
RESEARCH & PROPOSAL DEVELOPMENT
Concepts and project planning for combining textile residues with biobased polymer matrices. Not all proposed projects received funding.
Institutional links: Work and project development involving Empa and scientific contacts with European universities and research organisations. Industrial development partners are not identified here.
04 / ABOUT LUUUP
Where chemistry meets circular materials.
LUUUP was co-founded in St. Gallen in 2020. Its development activities connected academic research, innovation funding and implementation-oriented partners around the challenge of textile waste. The work documented on this site includes projects and prototypes developed over several years; it is not a catalogue of currently available products.
