Hackathon 2022 v4-06.png

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.

Who Are We Targeting?

1. University Students  

2. Hospitality Employees 

3. Innovators 

The World Needs Your Creativity to Drive A Sustainable Future! 


Food Technology

The amount of food waste produced daily in Hong Kong is 20 times than the amount of food produced locally. As for food waste from hotels and restaurants,
it is 6 times the volume of local food production.

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

Sustainable Packaging

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.
It does not stop there, back of houses use single plastic packaging in the form of cling film, wipes, gloves, masks, etc.

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.

Other than new technologies to remove stains more effectively, dyeing to cover stains is also an option chosen by some.

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