I make cardboard furniture

I detect cataracts with a mobile phone

I’m reducing crime with urban planning

I use oyster shells to make paint.

I’m a guerrilla gardener

My restaurant runs on hydroelectric energy

I created the zero waste festival

My third eye translates colours into sounds

I help people save for health care

I converted my city to vegetarianism

Trade your steak for bugs!

I make paper from stone

My invention revolutionises personal mobility

I heat your apartment with computing power

I created a network of solidarity supermarkets

I construct photovoltaic greenhouses to combine green energy with organic farming

La Nuit du Clean Tag

I use bamboo like others use iron

The statues I sculpt weigh only a few grams

Our bank lends buffaloes
