Post-industrial and 

post-consumer 
cotton, polyester 
and polycotton 
blends 
Dissolving pulp that 
can be processed into a 
continuous filament 
fibre with comparable 
characteristics to 
viscose (strength and 
cost). 
Polyester monomers of 
chemical equivalence 
to virgin monomers. 
A hydrothermal treatment process is 
used to separate and recover the 
material streams. Chemicals and dyes 
are separated in aqueous solution. 70% 
of water used in process is recycled, 
and waste water is treated by 
traditional waste water management 
process.

Post-industrial and 
post-consumer 
cotton, polyester, 
and polycotton 
blends (up to 20% 
other fibres and 
contaminants), 
post-consumer 
plastic materials 
(PET bottles, 
packaging) 
Worn Again (WA) 
Circular Cellulosic 
Pulp (competitive in 
quality and price with 
virgin resources)
WA Circular PET 
Pellets (virgin 
equivalent properties). 
A solvent-based recycling technology 
for separating and recovering cellulose 
and PET from waste textiles. The 
process enables contaminant, dye, and 
other polymer material separation.

The emergence of innovative technologies, new and alternative materials (i.e. bio-based) will help 
expand the availability of options in sustainable processing and sourcing. Table 13 features 
developments in new fibre materials (under development/demonstrated and commercialized).
