The Complete Guide to Composting Food Scraps in Your Kitchen

Have you ever wondered if it's possible to compost all those vegetable peels, eggshells, and coffee grounds right from your own kitchen? Composting kitchen scraps is an eco-friendly way to reduce waste and recycle nutrients to create rich, organic fertilizer for your garden or houseplants.

In this beginner's guide, you'll learn everything you need to start composting your food scraps at home, either indoors or outside. We'll cover what you can and can't compost, how to balance ingredients and maintain your compost pile, when your compost will be ready to use, and ways to use finished compost around your home.

Getting Started with Kitchen Composting

Composting seems complicated but it's actually quite simple. To get started, assess your living situation to determine if you'll compost indoors or outdoors. Outdoor composting requires more space but less effort while indoor systems work anywhere but require more maintenance.

Next, choose a composting method based on your needs. Outdoor compost piles are inexpensive and low-maintenance. Compost tumblers and bins contain the waste but require turning. Vermicomposting uses worms to break down scraps indoors.

Select a compost bin, tumbler, or worm bin based on your space and budget. Or, construct a simple outdoor compost pile in your yard or garden. Gather "browns" - dried leaves, shredded paper, or sawdust. Locate a sunny, well-draining spot for an outdoor pile.

What Can Be Composted from the Kitchen

Many typical kitchen scraps can go right into your compost, including:

• Fruits and vegetables - peels, skins, cores, tops, stalks
• Eggshells
• Coffee grounds and filters
• Tea bags
• Nutshells
• Houseplants
• Shredded newspaper
• Cardboard boxes
• Paper towels

Avoid any cooked foods, meat, fish, bones, or dairy products as these can attract pests and cause odors.

What Not to Include

Certain kitchen scraps should never go into your compost pile:

• Meat, fish, and bones
• Dairy products
• Oils and grease
• Animal waste
• Diseased plants
• Invasive weeds
• Pet waste

These materials contaminate compost and can potentially spread parasites, bacteria, and weed seeds.

Getting the Ratio Right

Achieving the right balance of "greens" and "browns" is important for efficient composting. Greens are nitrogen-rich fresh materials like fruit and veggie scraps. Browns are carbon-rich dried leaves, sawdust, or shredded paper.

The ideal ratio for compost is 2 parts browns to 1 part greens. Too many greens causes odors while too many browns slows decomposition. Calculate ratios by volume - not weight.

If your compost smells bad, add more browns. If decomposition is too slow, incorporate more greens. Fine tune based on your conditions and materials.

Maintaining Your Kitchen Compost

Proper maintenance yields faster, higher quality compost:

• Moisture: Compost should be damp but not soggy. Add water if too dry or turn pile to dry out excess moisture.
• Aeration: Turn or stir the compost weekly to circulate air and speed decomposition.
• Odors: Bad smells indicate excess moisture or too many greens. Turn the pile and add browns to improve aeration.
• Pests: Rodents and flies can be deterred with a lidded bin. Only add acceptable scraps.

Monitor temperature - compost heats up during decomposition then cools as it cures. Turning the pile periodically prevents overheating and kills weed seeds and pathogens.

Knowing When Your Compost is Finished

Finished compost is dark, crumbly, and earthy-smelling. It resembles soil, not the original waste items. Finished compost:

• Does not resemble the original materials
• Does not heat up after turning
• Has an earthy smell
• Can be used to grow plants

Home compost typically takes 2 to 3 months to fully decompose. Smaller pieces break down more quickly. Avoid adding new materials as existing waste nears completion.

Using Compost in the Kitchen

Your homemade compost has many uses right in your home and kitchen:

• Amend garden beds and houseplant pots by mixing compost into soil
• Create nutrient-rich compost tea to water plants
• Top-dress lawns and grassy areas
• Enrich potting mixes when re-potting plants
• Blend custom potting soils

Use finished compost anywhere you would use store-bought fertilizer. Your plants get a slow-release, organic nutrient boost.

Going Beyond the Kitchen

Once you master composting kitchen scraps, consider expanding your waste diversion. Here are some next steps:

• Add yard waste - leaves, grass clippings, weeds
• Join a community composting program
• Advocate for city-wide composting
• Learn about large-scale municipal composting
• Support zero-waste initiatives

Talk to neighbors about starting a community compost pile. Contact local government to urge more composting legislation. Small daily actions lead to wider systemic change.

While composting itself is ancient, new technologies are improving results:

• Special bins speed decomposition and reduce odors
• Vermicomposting innovations like continuous-flow worm bins
• Apartment and urban composting solutions
• Advanced municipal composting that removes contamination

From simple backyard compost piles to high-tech urban digestion facilities, composting is an accessible way to create something new from old food scraps.

Want to give composting a try? Start small by collecting kitchen waste in a countertop bin. Invest a little time each week maintaining your pile. Soon you'll have rich compost to nourish your plants.
