Humans waste a lot of food.

That food waste piles up in landfills faster than it can decompose, releasing methane, a greenhouse gas that’s 28 times more potent than carbon dioxide and becomes acidic enough to release potentially harmful chemicals from plastics, metals, and other trash that’s piling up alongside it.

If we just disposed of food waste in a more effective manner, it could instead be a good thing, which is the entire principle behind composting. Composted food waste has the potential to be utilized as fertilizer while also not contributing to landfill overflow.

Enter: Worm composting.

Composting typically requires outdoor space to allow your food waste to decompose — something that not everyone has. That's where vermicomposting, or worm composting, comes in. Vermicomposting can be done indoors or outdoors, in a relatively small bin that can fit in a modest home or apartment. You'll just need some earthworm roommates who will take care of the waste for you.
