Home composting diverts organic waste from landfills and produces nutrient-rich soil amendment for gardens. The EPA estimates that food scraps and yard waste make up over 30% of household trash. However, not everything organic belongs in a compost bin—some materials attract pests, introduce disease, or simply will not break down in a home system.
Successful composting requires a balance of "greens" (nitrogen-rich materials like fruit scraps and grass clippings) and "browns" (carbon-rich materials like dried leaves and cardboard). Our composting guides cover specific items, explain the science behind decomposition, and help you avoid common mistakes like adding meat, dairy, or treated wood.
