The single most impactful thing you can do to reduce kitchen waste is to stop throwing away food scraps. Composting is nature’s recycling program—a simple process that transforms organic waste into a rich, dark soil amendment that your plants will adore. It might seem intimidating, but the basics are surprisingly simple. This guide will teach you how to turn your scraps into “black gold.”
Understanding the Two Colors of Compost: Greens and Browns
A healthy compost pile requires a balance of two types of materials:
- Greens (Nitrogen-rich): These are the “wet” materials that heat up the pile. Think of things like fruit and vegetable scraps, coffee grounds, fresh grass clippings, and eggshells.
- Browns (Carbon-rich): These are the “dry” materials that provide structure and aeration. This includes things like dried leaves, cardboard, newspaper, wood chips, and straw.
A good rule of thumb is to aim for a ratio of roughly 3 parts Browns to 1 part Greens. Too many greens can lead to a slimy, smelly pile, while too many browns will slow down decomposition significantly.
Choosing Your Composting Method
- The Open Pile: The simplest method. If you have backyard space, you can simply start a pile in a discreet corner. It’s low-cost but can be slower and may attract pests if not managed well.
- The Compost Bin: A contained unit (plastic or wood) helps keep the pile tidy, retain heat, and deter animals. You can buy a tumbler, which makes turning the pile easy, or a stationary bin.
- Worm Composting (Vermicomposting): Perfect for apartments and small spaces! A worm bin is a self-contained ecosystem where red wiggler worms do the work for you, breaking down food scraps into nutrient-dense worm castings. It’s odorless and can be kept indoors or on a balcony.
What You CAN and CANNOT Compost
- YES, Compost This (Greens): Fruit & vegetable scraps, coffee grounds & filters, tea bags (staple removed), eggshells (crushed), old flowers, grass clippings.
- YES, Compost This (Browns): Cardboard (shredded), paper, dried leaves, wood chips, sawdust, dryer lint (from natural fibers).
- NO, Do Not Compost This: Meat, fish, dairy products, grease, or oils (these attract pests and create foul odors). Also avoid diseased plants, pet waste, and charcoal ash.
How to Maintain Your Compost
- Aerate: Turn your pile with a pitchfork or by tumbling the bin every week or two. This introduces oxygen, which is essential for the microorganisms doing the decomposition work.
- Monitor Moisture: Your compost should feel like a wrung-out sponge. If it’s too dry, add some water. If it’s too wet, add more brown materials.
- Be Patient: Depending on your method and maintenance, you could have finished compost in as little as a few months or up to a year.
When is it Ready?
Your compost is ready to use when it’s dark, crumbly, and smells like rich, fresh earth. You should no longer be able to identify the original food scraps. Once it’s ready, sift out any large, unfinished pieces and spread this incredible, homemade fertilizer on your garden beds, potted plants, or lawn. You’ve officially closed the loop on your kitchen waste.
