SUSTAINABILITY• Reduce

Material RecycleChemical RecycleThermal Recycle

REUSE• The garments are composed of many parts made of various fibers, which are sewn together.

• By taking off sewn threads, each part of a garment is separated into respective pieces.

• Some pieces could be reused.

• Sewing thread which will be dissolved in hot water (over 130C) could be available.

RECYCLE• Most of the fabrics for garments are composed of various sources of fibers, but cotton and polyester share over 80 % of

fabric resources.

• A priority is thus given to recycle cotton and polyester.

• No fiber-to-fiber recycling process is available.

• A hydrothermal process is capable of separating cotton/PET blends and recovering PET fiber without deterioration.

• This new hydrothermal process is considered as the intermediate between reuse and material recycling. No further chemical process is needed for recovered PET.

HOW TO LOOP• Designers’ challenge for easy recycling by standardizing each element composing a garment.

• A new design could be made by a variety of combination of elements.

• Sewing could be made by hot-water (over 130C) soluble thread.

• Collected old clothes are separated to respective elements, some of which could be reused for a new design.

• The rest could be recycled by a hydrothermal process and recovered PET be processed into yarn.
