Table 9: Cotton - Chemical Recycling Stakeholders Company Feedstock/Input, Requirements Product/Output Processes Evrnu 102-104 (USA)
Post-consumer
cotton textile waste
Regenerated
cotton/cellulosic fibre
Properties: can be
dyed efficiently with
ability to add
moisture-wicking or
anti-microbial
properties.
103
Solvent used for cellulose dissolution,
polymerization, and extrusion into
regenerated cellulosic fibre. Evrnu
proprietary technology can strip down
cellulose to a pure carbon chain that is
three times stronger than steel. The
technology can also simulate other
fibres (end-products) such as rayon,
polyester.

Ioncell 105 (Finland)
Dissolving pulp,
paper grade pulp
from Kraft pulping
process, waste
paper and
cardboard, waste
cotton
Ioncell-F
Cellulosic fibre
Properties: moisture
absorbing,
biodegradable, high
lustre, can be dyed
with same processes as
cotton and viscose
Ionic liquid used for cellulose
dissolution. Fibre filaments produced
through dry-jet wet spinning. Ionic
liquid is recovered as aqueous
solution, and separated from water, to
be re-circulated in the process.

Refibra™
Respinning of cotton with cellulosic
reinforcement (classified as MMCs).
Re:newcell 106 (Sweden)
Post-consumer
cellulose-based
textile waste, high
cellulosic content
(cellulose and
viscose)
re:newcell cellulosic
pulp for use in
recycled fibre
production (lyocell
process)
Cellulosic waste sorted and shredded.
Decolorization is performed, turning
waste into a slurry. Slurry is dried,
producing pure, natural re:newcell
pulp, used for textile production.
re:newcell pulp found to have higher
mechanical properties than wood-
based dissolving pulps, as well as
better dyestuff absorption.
