International Compost Awareness Week (ICAW), celebrated annually during the first full week of May, is the largest and most comprehensive education initiative of the compost industry. In 2025, ICAW takes place from May 4–10, aiming to raise public awareness on why we all should be composting our organics and using compost to create healthier soil.
Why Compost?
Composting is a natural process that transforms organic waste into nutrient-rich soil, commonly referred to as "black gold." By composting, you reduce the amount of waste sent to landfills, decrease methane emissions, and enrich your garden soil. According to the U.S. Environmental Protection Agency (EPA), composting at home is a straightforward way to reduce food waste and create nutrient-rich soil for your garden.
Getting Started: A Simple Guide to Home Composting
1. Choose Your Composting Method
- Backyard Composting: Ideal if you have outdoor space. Use a compost bin or pile to collect organic waste.
- Indoor Composting: Suitable for apartment dwellers. Options include vermicomposting (using worms) or Bokashi systems.
- Community Composting: Some municipalities offer compost collection services. Check local programs.
2. Understand What to Compost
Greens (Nitrogen-rich materials):
- Fruit and vegetable scraps
- Coffee grounds and filters
- Tea bags (without staples)
- Crushed eggshells
Browns (Carbon-rich materials):
- Dry leaves
- Shredded newspaper
- Cardboard
- Sawdust
Avoid:
- Meat and dairy products
- Oily foods
- Pet waste
- Diseased plants
3. Maintain the Right Balance
Aim for a ratio of about 2–3 parts browns to 1 part greens. This balance ensures efficient decomposition and minimizes odors.
4. Aerate Your Compost
Regularly turning your compost pile introduces oxygen, speeding up the decomposition process and preventing unpleasant smells.
5. Monitor Moisture
Your compost should be as moist as a wrung-out sponge. If it's too dry, add water; if too wet, add more browns.
Tips to Avoid Odors and Pests
- Chop Waste: Cutting scraps into smaller pieces accelerates decomposition.
- Cover Food Scraps: Always cover fresh additions with browns to deter flies.
- Use a Lid: Keep your compost bin covered to maintain moisture and keep pests out.
- Avoid Certain Foods: Steer clear of composting meat, dairy, and oily foods, as they can attract pests and produce odors.
