Textile Innovation

The Green Machine

The Green Machine is a project by HKRITA. It is an efficient hydrothermal treatment method to decompose cotton into cellulose powders, hence enabling the separation of the polyester fibres from the blends for easier recycling. Once separated, the polyester fibres and cellulose powder can both be respun.


About HKRITA: Established in 2006, HKRITA is funded by the Innovation and Technology Commission of the HKSAR Government and is hosted by The Hong Kong Polytechnic University. HKRITA contributes to the competitiveness of the textile and apparel industry by providing one-stop services in applied research, technology transfer and commercialisation. HKRITA also plays a vital and expanding role in driving sustainable improvements in the industry and thus bringing benefits to society as a whole.

Conversion of Food Waste into Polylactic Acid Fibre

This is another project by HKRITA. HKRITA aims to study novel bioprocesses using food wastes for the sustainable production of polylactic acid fibre in textile application. The outcomes of the proposed project are expected to contribute in sustainable production of polylactic acid fibre production, and novel approaches of food waste treatment.

This is another project initiated by HKRITA located at the Mills. Set up in 2018, the Garment-to-Garment Recycle System is the mini-scale production line set up in a retail shop recycling post-consumer garments to a new one. It is an environmentally friendly process without using any water and chemicals.

Packaging Innovation


Planeteers’ mission is to cultivate sustainable and healthy eating habits in Hong Kong. They envision replacing disposable cutlery with incrEDIBLE! - our 100% vegan, delicious, and crunchy edible cutlery.

If one is too full to eat it, it can biodegrade completely, enabling an end-to-end closed life cycle loop. Their beneficiaries include our partner restaurants, local bakeries, and diners, who are all part of the green revolution to fight the harmful health and environmental effects of plastic and wooden cutlery.

By 2023, they aim to replace 9 tonnes of disposable cutlery, which is equivalent to planting 11,000 trees in Hong Kong!

So, bon appetite!
