Composting kitchen scraps at home is an eco-friendly way to reduce waste, enrich your garden soil, and promote sustainable living. This step-by-step guide will help you start composting your kitchen leftovers easily and efficiently.

What Kitchen Scraps Can You Compost?

Compostable kitchen scraps fall into two main categories, often called greens (nitrogen-rich materials) and browns (carbon-rich materials).

Greens (Nitrogen-Rich)

  • Fruit and vegetable peels and scraps
  • Coffee grounds and filters
  • Tea bags (ensure they are plastic-free)
  • Eggshells (crushed)

Browns (Carbon-Rich)

  • Paper towels and napkins (unbleached)
  • Shredded newspaper
  • Cardboard (small pieces)
  • Dried leaves

Avoid composting: Meat, dairy, oily foods, diseased plants, and pet waste, as these can attract pests and create odors.

Supplies Needed

  • A compost bin or heap (can be indoor or outdoor)
  • Kitchen scrap container or caddy
  • Garden fork or compost aerator

Step-by-Step: How to Compost Kitchen Scraps

  1. Choose Your Composting Method
    • Outdoor bin or pile: Best for larger yards.
    • Indoor compost bin: Ideal for apartments (use sealed containers or worm bins).
  2. Collect Kitchen Scraps
    • Store scraps in a countertop caddy or small bin with a lid.
  3. Add to Compost Pile
    • Alternate layers of greens and browns.
    • Keep the ratio roughly 2:1 (browns:greens) for optimal decomposition.
  4. Maintain Moisture and Aeration
    • Compost should feel like a wrung-out sponge—add water if dry, browns if too wet.
    • Turn the pile every 1–2 weeks to add oxygen and speed up the process.
  5. Wait for Compost to Mature
    • Compost is ready in 2–6 months. Finished compost is dark, crumbly, and earthy-smelling.

Tips for Successful Composting

  • Chop or shred larger materials for faster breakdown.
  • Keep the bin covered to retain moisture and keep pests away.
  • Use finished compost in your garden beds, potted plants, or as lawn top-dressing.

Benefits of Composting Kitchen Scraps
