Introduction

Landfill sites are an icon of our wasteful society and the harm we cause to Planet Earth.

But around the world, people are trying to make these filthy places a little bit better.

We visit the human-built island in Singapore made of burned waste that has become a thriving ecosystem.

And in France, we hear how gas leaking from landfill sites is being collected as a source of energy.
