So, why compost?

Healthy crops: Bay Area farmers use City compost as nutritious fertilizer to grow world-class produce.

Fight climate change: Food that goes to landfill creates methane gas, which is 25 times more potent than carbon dioxide and worsens the climate crisis. When you compost in SF, it’s processed at a special facility where methane gas is captured and used to power Recology trucks and facilities.

Breathe easier: Plants grown in compost-rich soil naturally absorb carbon dioxide, another potent gas that contributes to climate change. More plants means more oxygen and less carbon dioxide in the atmosphere.

Create jobs: Composting creates three times more jobs than landfilling.

Fight food waste: Nearly 40% of food in the US is wasted every year, yet 1 in 8 Americans experience food insecurity. Give discarded food scraps a second life—eat up and compost the rest.

Save water: Applying compost to topsoil helps it retain water and slows down soil erosion, which may even reduce the risk of forest fires.
