We match people who make compost at home with neighbors who contribute their food scraps and waste.

Keepers are those who have mastered the alchemy of turning food scraps into living soil — or those who are learning to.

Contributors are those who no longer want to be part of the 35 million tons of food waste sent to landfills each year. They bring their food scraps to nearby heaps, which the Compost Keepers shepherd back into nourishing soil. facilitates communication around the heaps so that everyone involved (including the microbes) has a really good time.

This means:

  • making it clear whether the pile is open to new contributors, or whether it's fully subscribed.
  • making it easy to know what matter a heap does and does not accept
  • providing other instructions about how to make deposits to a particular heap
  • broadcasting requests from Keepers to Contributors ("Anyone have sawdust or leaves?" "More coffee grounds please, they heat up the pile and smell nice!")
  • And other tools to help communities to come together to create new, living soil.


Earth has some problems. Sprawling landfills are one. The depletion of topsoil is another.

Landfills turn our beautiful planet into places where no one wants to live, while the topsoil we depend on to grow our food is giving up its nutrients faster than we are giving them back.

Composting solves both.

When we compost our food waste and paper products, we keep valuable organic matter from needlessly filling up landfills while generating new living, nourishing soil.

But today, very little of our food waste is composted. Few cities offer municipal composting services and few people make compost or understand what it really is. With most of the planet's 7.5 billion people sending their food waste to landfills daily, it's a mistake we can no longer afford make.

The good news is that we don't need to wait for governments to change, or for global catastrophe to force us to change. We already know there is a more beautiful way.

Why treat the planet like garbage when we can compost instead?
