"I saw the amount of rubber waste from the process of producing bedding toppers at my family's manufacturing business, and I thought to myself that the waste could be used to make something that was needed in the market," said Yosita, who is still a student at Bodindecha (Sing Singhaseni) School in Bangkok.

Inspired to take the idea further, she tested various potential end-uses for the waste rubber over a period of more than three months, and finally decided upon making rubber-foam pillows - as well as cushions - for health.

The waste rubber from the family bedding-topper business is recycled into grain latex foam, by cutting the rubber into small pieces, then mixing them together into a foam.

This results in material for a pillow that is good for one's health, because 100 per cent natural latex foam conforms to the contours of the head, neck and spine for optimal orthopaedic support, she explained.
