Never Too Young to Make an Impact
Never Too Young to Make an Impact
Three teams of students emerged victorious from the Young Technopreneurs for a Sustainable 2030 challenge in October 2019. They will now be making a visit to Japan to learn how to develop their products further.
The sweetness of an ice-cold milk tea coupled with the chewy sensation of tapioca balls not only quenches one’s thirst from the heat, but also creates a bursting, refreshing mix of flavours in the mouth! Widely popular in the region, bubble tea has become a mainstay of the local cultures today. However, this beverage also generates enormous amount of plastic waste.
While reusable straws have emerged as sustainable solutions, there is still no alternative to plastic cups. But a trio of environmentally-savvy students from Tanjong Katong Girls School found ways to recycle these items more easily.
Andrhea San Gabriel, Faith Tan and Kitiara Ong devised a machine that washes single-use bottles and cups, allowing them to be cleaned for recycling.
Their project was one of the winining sustainable solutions from the Young Technopreneurs for a Sustainable 2030, a nationwide challenge open to students between 13 and 18 years of age. The challenge is presented by Temasek Foundation and organised by Science Centre Singapore.
The competition, which culminated with a showcase at the Singapore Maker Extravaganza in October 2019, aims to encourage students to develop sustainable solutions in line with the United Nations Sustainable Development Goals. Through the competition, Temasek Foundation seeks to inspire and empower more people, especially the young, to develop their passion and capability, as well as to build a vibrant community to address critical sustainable development issues.
Along with two Junior category winning teams, the girls behind Washing Recyclable Bottles topped 15 finalists shortlisted from 70 teams comprising over 200 participants from 41 schools. The three winning teams will head to Japan in March 2020 to explore tech start-ups and fabrication spaces.
Washing Up for Recycling
Recyclables are typically dumped into recycling bins without being cleaned first, which contaminates and makes them unfit for recycling.
The Washing Recyclable Bottles team realised that people were unlikely to rinse their plastic bottles and cups outside, so they built an automated bottle washer to encourage the public to go green.
“We decided to create a machine that could be implemented in public areas for convenience,” explained Faith, 16.
Users attach a bottle or cup to tubes fitted inside a glass box and watch the recyclables get rinsed before being dropped into a recycling bin.
“We made it convenient and entertaining so that kids would be interested to pick up recycling,” added Kitiara, 16, whose team had to juggle their O-Levels preparation with the competition that included an online start-up boot camp and a hackathon.
They also received public and peer feedback on possible improvements such as keeping their wires neat and making the lid less heavy for children.
“It made us think about how to overcome constraints and make our product more applicable to people,” said Andrhea, 18.
From Fruit Peels to Paper
Naga Sai sat in his room for weeks trying to figure out the electronics for his team’s Fiper project to make paper from fruit peels.
His nine-volt batteries frequently short-circuited the contraption, which consists of two flat pieces of wood supporting a third above. A brick suspended on top would then be released to crush blended fruit peels soaked with soda ash into paper peels on a board below.
“It’s frustrating when the batteries don’t work, and there’s always the smell of burnt plastic in my room,” noted Sai, whose School of Science and Technology team was joint winner of the Junior category.
Typically, it takes five hours to make paper. But the process could be shortened to just two hours using Fiper.
While Sai experimented, his teammates Chua Wen En and Brian Yeo refined their business pitch and figured out how to best build their project.
The 14-year-olds were determined to do it themselves, even though their mentors at the Sustainable Living Lab – a social enterprise promoting sustainability – were able to help.
“We learnt how to drill and attach the parts, and usually stayed in school until the security guard chased us out,” said Wen En, who made four prototypes with his team.
They aim to market their product in the food industry. In particular, they are targeting drink stalls, which have an abundance of fruit peels. Now, they hope to learn from Japanese experts on how to improve their prototype.
Delivering Food in an EcoBox
A casual remark by their teacher over lunch led to a eureka moment for Kamalini Chelladurai and Kyi Thanthar, co-winners in the Junior category.
“He talked about his army days when he used a lunch box without cutlery,” recalled Kamalini, 15. “We then started brainstorming if we could make a convenient and eco-friendly box.”
The duo from Queensway Secondary School eventually invented EcoBox, a lunchbox made from biodegradable plastarch that comes with perforated cutlery. They engaged a box manufacturer to create the product.
The EcoBox will be paired with an app called ECOworld – developed by coding company Spritle Software – that would allow users to redeem food delivery vouchers by scanning a QR code found in the box.
They also have several plans to push out their product. One is to work with companies such as FoodPanda and Deliveroo, where an option to use an EcoBox will be made available.
The other is to partner the National Environment Agency to collect used boxes for recycling.
While it is still early days for these enterprising youths, the competition has provided them a platform to flourish. Their work towards a sustainable future begins now.
