Zero Waste for Clean & Green Hackathon

Zero Waste for Clean & Green Hackathon

A Clean & Green Hackathon is a fun and collaborative event where people volunteer their time to work on ideas to solve challenges. Singapore’s National Environment Agency is sponsoring the latest from 16-21 June – two years after the country’s first Clean and Green Hackathon – with the emphasis this time on how to change people’s mindset and behaviours towards a cleaner and zero-waste city state.  People from diverse backgrounds –  from coders, designers, students and business executives -   are called on to bring their skills and knowledge into play. But this is serious! Read More


19 to 21 June 2015!

An active and gracious community respects the environment and one another by caring about their neighbourhoods and shared spaces. These shared spaces may be the void decks in our HDB estates, the park connectors, the surrounds of our sporting and entertainment facilities, and everywhere in between.

Everyone in the community has an active role to play. We invite you to come and explore new ideas to help strengthen ownership of the environment.

Challenge: Reduce Littering

Sporting and Leisure Events

Singapore is a hub for international events – sporting events like SEA Games, and concerts etc. that attract many attendees. How can we galvanise everyone to help keep our public spaces like stadiums, sports venues, event locations etc. clean? How can we encourage and remind event-goers to bin their litter properly?


Public cleanliness is important not only during events, but at all times, as litter creates an eyesore and clogs up our drains. It affects public health and our quality of life. Through the years, we have come to rely on cleaners to pick up after us. As we collectively impact the cleanliness of our neighbourhoods and share the use of our public spaces, we all need to play a part in maintaining them. How can we get our neighbours to take action in keeping our shared spaces clean?

Challenge: Reduce and Recycle Waste

Singapore’s overall recycling rate was 60% in 2014 and only 19% of the waste generated by households is recycled. A significant increase is needed in order to achieve the target of 70% overall recycling rate by 2030. At the same time, a large number of litter left behind at public events were single-use disposables such as drink bottles, cans and ponchos, while waste generated at home typically include recyclables, such as paper / plastic packaging, drink bottles and biscuit / milk tins. How can we educate and remind event-goers and residents alike to reduce the use of disposables, reuse and / or recycle their waste responsibly?

Have you got an idea on how to change people’s mindset and behaviours towards a cleaner and zero-waste Singapore? Or are you keen on joining the discussion, brainstorm and work with like-minded people on new ideas? This hackathon is for you!

You’ll get a wonderful opportunity to work alongside passionate citizens wanting to make a positive change in our community. We will also be joined by specialists in sustainability and green technologies, experts in behavioural change, user experience designers, etc.
