I created a universal language for the deaf community

I created a deodorising fabric with coffee grounds

Our students pump fresh water on the playground

I cross oceans in a boat made of jute

I pay you back for recycling

I fly with migrating birds

I doubled green space by building a hotel

I make 100% biodegradable chewing gum

I’ve pioneered diaper recycling

I’ve helped a million Filipinos out of extreme poverty

I created the first medical Facebook

I rent out my goats to mow your lawn

I use bamboo like others use iron

I created the Ethical Fashion Show

I co-created the world’s first chain of eco-hotels

I created an open-source machine to make natural dyes. 

I created the world's simplest toilets

I wash cars without water

My radiator is inspired by the sun

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