Two Ngee Ann Polytechnic students from Singapore have designed a solution to reduce plastic waste from dental floss picks.

Lingesh Sachuvanantham and Javen Koh co-founded a company named Kloss to produce biodegradable and reusable floss picks.

In 2022, their concept won second place at a school sustainability challenge by Junior Achievement Singapore.

With a US$3,000 prize, they purchased a US$220 3D printer to start making floss picks from natural materials.
