I make cardboard furniture

My third eye translates colours into sounds

I use dogs to sniff out prostate cancer

I’m a guerrilla gardener

I transform unsold newspapers into eco-bags.

These wood bricks don't need nails, screws, or glue

I’ve pioneered diaper recycling

I’ve helped a million Filipinos out of extreme poverty

My radiator is inspired by the sun

I converted my city to vegetarianism

We're bringing light where the sun doesn't shine

I make soap from used cooking oil

My invention could save your skin

I bring light slums with our old plastic bottles

I created a new kind of citizen action

I recycle plastic bags in New Delhi

I rediscover the beauty of small meadow flowers through my camera lens.

Our students pump fresh water on the playground

I created Clean Up Day

My technology reduces shipping emissions
