What is The Theme for This Year? 

Circularity in Hospitality - Transforming Waste into Solutions

Following up on the footsteps of the Green Hackathon 2020 in which the theme revolved around innovative ideas for waste management and segregation within the Hospitality sector.

In 2022 we want to go further in search for innovative ideas on how to recreate products and solutions for the Hospitality industry from waste, in a drive towards a full circular economy within the sector. 


The Tourism & Hospitality sector in Hong Kong needs
your creativity to drive a sustainable future. 



Challenge Anchor

Food Technology

In hotels, a large part of the problem are buffets where dishes are replaced even before they are finished to convey freshness. This causes a large portion of the food displayed going in the bin.

What other things can be created out of food waste? What are the potential products that can be made? 


Use of single-waste plastic is common in hotels, be it water bottles, coffee cups, earbuds, toiletry bottles, snacks, slipper wraps or more recently balloons.


What innovations can be made with packaging waste?


Textile Innovation

Every hotel uses numerous linens and textiles for bedsheets, tablecloths, towels, etc. These textiles must remain in pristine conditions as “spotlessly clean beddings” are a top priority for many hotel guests.

What are some creative ways to repurpose these textiles and give them a new life?
