Circular fashion: textile collection & sorting

Collection, automated sorting and fiber-to-fiber recycling of post-consumer textile waste — the infrastructure layer turning Europe's 12+ million tonnes of annual clothing waste back into new fibers under the EU Circular Textiles strategy, led by Circulose, Infinna and automated sorters, alongside honest commercial scale-up retrenchments.

1 · What it gives

Circular fashion is the infrastructure layer that closes the textile loop: collecting post-consumer clothing, sorting it automatically by fiber, and recycling it back into new fibers. Europe generates more than 12 million tonnes of textile waste a year, yet under one percent is recycled into new fiber — the gap the EU Strategy for Sustainable and Circular Textiles and national Extended Producer Responsibility (EPR) schemes now force the industry to close. The stack has three layers: automated sorting (Tomra, Refiberd hyperspectral AI), mechanical and chemical fiber-to-fiber recycling (Renewcell’s Circulose cotton pulp, Infinited Fiber’s Infinna), and polycotton separation (Circ’s hydrothermal process, Worn Again). The field is also commercially honest: Renewcell entered restructuring in late 2023 after its 60,000-tonne Sundsvall Circulose plant struggled with offtake, and is restarting under new ownership as brand partners sign on — a clear signal that the technology works but the offtake economics are still maturing.

The key directions of circular fashion are:

Automated textile sorting (Automated Textile Sorting): hyperspectral and AI sorting that classifies post-consumer garments by fiber composition at industrial throughput — Tomra Textiles Autosort, Refiberd Fiberhook.
Mechanical cotton recycling (Mechanical Cotton Recycling): chemically pulping cotton waste into a dissolving-pulp feedstock for virgin-grade viscose and lyocell — Renewcell Circulose.
Cellulose-carbon fiber regeneration (Cellulose Regeneration): turning cellulose-rich textile waste into regenerated fiber (Infinited Fiber Infinna, carbamate process).
Polycotton separation (Polycotton Separation): hydrothermal or solvent processes that separate the polyester from the cotton in blended fabrics so each stream can be recycled — Circ, Worn Again Technologies.

United States

The United States is building a textile-recycling base driven by emerging state EPR laws and AI-sorting start-ups, with capital flowing into both sorting and chemical recycling.

AI sorting, polycotton chemical recycling, EPR drivers#

Refiberd: an AI textile-sorting company whose Fiberhook platform uses hyperspectral imaging to classify post-consumer textiles by fiber at commercial throughput as US textile recycling matures alongside EPR.
Circ: a polycotton hydrothermal recycling company building a roughly 500-million-dollar facility in France to scale its polyester-from-polycotton process with fashion-brand offtake.
EPR emergence: emerging US state extended-producer-responsibility schemes are creating the feedstock and funding that automated sorting and recycling plants need to scale.

European Union

Europe authored the circular-fashion policy framework (EU Strategy for Sustainable and Circular Textiles, EPR, digital product passport) and hosts the densest cluster of fibre-to-fibre recyclers.

Circulose (Renewcell), Infinna (Infinited Fiber), Tomra sorting#

Renewcell (Sweden): the Circulose dissolving-pulp process turns cotton waste into virgin-grade feedstock; after the 60,000-tonne Sundsvall plant entered restructuring in 2023, the plant is restarting under new ownership as brand partners sign offtake.
Infinited Fiber Company (Finland): the Infinna regenerated-fiber process turns cellulose-rich textile (and agricultural) waste into a cotton-like fiber used by global fashion brands.
Tomra Textiles (Norway): automated hyperspectral sorting systems that classify post-consumer garments by fiber composition at industrial throughput, the entry point of the whole recycling chain.
Worn Again Technologies (United Kingdom): the Accelerator polycotton separation process recycles polyester-cellulose blends into both polyester and cellulose outputs.

China

China is the world’s largest textile manufacturer and a growing recycler, integrating mechanical and chemical recycling into its domestic fiber supply.

domestic rPET fiber, manufacturer-led recycling, scale#

Domestic rPET fiber: China is the largest producer of recycled-polyester (rPET) fiber from bottle and textile feedstock, integrated into the world’s biggest textile manufacturing base.
Manufacturer-led recycling: large Chinese fiber and chemical-fiber producers integrate recycled-content lines, driven by brand sustainability commitments and domestic policy.
Collection infrastructure: formalised textile recycling chains are expanding under national circular-economy policy, though collection rates still trail the European EPR-driven model.

7 · Tech stack & innovations

The circular-fashion stack rests on sensing, separation chemistry and offtake economics, each layer hardened by a decade of pilot-scale learning.

Hyperspectral/AI sorting (Hyperspectral/AI Sorting):
- near-infrared and hyperspectral cameras classify each garment’s fiber composition in milliseconds on a conveyor, enabling one-item-per-second industrial sorting.
- the sorted fractions (cotton, polyester, polycotton, wool) then route to the matching recycling process.
Mechanical cotton-to-pulp recycling (Mechanical Cotton Recycling):
- cotton waste is chemically pulped into dissolving pulp (Circulose) that feeds virgin-grade viscose and lyocell spinning.
- Renewcell’s 60,000-tonne Sundsvall plant is the scale reference, now restarting under new ownership.
Polycotton hydrothermal separation (Polycotton Separation):
- hydrothermal or solvent processes selectively dissolve the polyester from polycotton blends, leaving a clean cellulose stream so both components recycle.
- Circ’s process underpins its roughly 500-million-dollar France facility with brand offtake.
