Woodlands Secondary students win award for paint made from egg shells


Woodlands Secondary students have found a way to recycle egg shells and clam shells to create environmentally-friendly paint.

While paint is normally made from calcium carbonate extracted through mining and quarrying, the group of four students has found an alternative method to extract the compound for paint.

The students, who are now in Secondary Two, partnered Nippon Paint, and they crushed and filtered the shells to extract the calcium carbonate. Their paint passed the standard tests and is comparable to normal quality paint.

For their efforts, the group received the top award in the secondary school category of the Green Wave Environmental Care Competition organised by SembCorp Marine's subsidiary, Sembawang Shipyard.
