Why Compost Your Kitchen Scraps? The Big Benefits
Before we dive into the “how,” let’s chat about the “why.” Composting kitchen scraps is more than just a trend; it’s a smart way to handle waste and boost your garden. Think of it as giving your ecosystem a helping hand.
Environmental Wins
- Reduces Landfill Waste: About 30% of what we throw away is food scraps and yard waste. Composting diverts this from landfills, where it produces methane, a potent greenhouse gas.
- Creates Nutrient-Rich Soil: Compost is like a multivitamin for your soil. It improves soil structure, helps it retain moisture, and provides essential nutrients for plants.
- Decreases Need for Chemical Fertilizers: Using compost means you’ll likely rely less on synthetic fertilizers, which can harm the environment.
- Conserves Water: Compost-amended soil holds more water, meaning you’ll need to water your plants less often.
Home & Garden Perks
- Healthier Plants: Plants grown in compost-rich soil are often stronger, more resistant to pests and diseases, and produce better yields.
- Saves Money: You’ll buy fewer bags of soil amendments and fertilizers. Plus, reducing waste can sometimes lower trash fees.
- It’s Rewarding: There’s a unique satisfaction in transforming waste into something valuable for your garden.
Getting Started: What You’ll Need for Kitchen Composting
The beauty of kitchen composting is that you don’t need a huge backyard or fancy equipment. You can start small, right in your kitchen or on a balcony. Here’s a quick rundown of the essentials:
Your Composting Bin: The Right Home for Your Scraps
Choosing a bin depends on your space and how much kitchen waste you generate. Here are popular options:
- Countertop Compost Bin: These are small, often stylish containers you keep on your kitchen counter. They’re great for collecting scraps before you take them to your main compost pile or bin. Many have charcoal filters to keep smells at bay.
- Worm Composter (Vermicomposter): If you’re short on space or want a super-efficient method, a worm bin is fantastic. Red wiggler worms do the hard work, breaking down food scraps quickly. These are ideal for apartments or small homes. For more on setting up a worm bin, check out this guide from the Cornell University Composting Program.
- Outdoor Compost Bin: If you have a bit of yard space, an outdoor bin is common. These can be purchased plastic bins, wooden structures, or even simple DIY piles. They’re good for larger volumes of kitchen scraps and other organic materials.
- Bokashi Bin: This is a bit different. It’s an anaerobic (oxygen-free) fermentation process that pickles your food waste using a special bran. It can handle items others can’t (like meat and dairy), and the fermented material then needs to be buried or added to a traditional compost pile to finish decomposing.
Tools You Might Find Handy
You don’t need much, but a few items can make the process smoother:
- Kitchen Tongs or a Small Spade: For turning your compost pile if it’s an outdoor bin.
- Watering Can: To keep your compost moist if it’s outdoors.
- Kitchen Scraps Collection Container: Any bowl, bucket, or dedicated countertop bin will do.
- Garden Gloves: For when you’re handling finished compost or turning larger piles.
The Kitchen Compost Recipe: What Goes In (and What Stays Out!)
Think of composting as creating a balanced meal for your compost microbes. They need a mix of “greens” (nitrogen-rich) and “browns” (carbon-rich). Your kitchen scraps are mostly greens, so you’ll often need to add browns.
“Green” Materials (Nitrogen-Rich) – Your Kitchen Scraps!
These are generally moist materials that provide nitrogen. Most kitchen scraps fall into this category:
- Fruit and vegetable peels and scraps
- Coffee grounds and paper filters
- Tea bags (remove any staples or plastic tags)
- Eggshells (crushed finely)
- Stale bread, pasta, rice (in moderation, can attract pests if too much)
- Plate scrapings (avoiding oily or fatty foods if using outdoor bins, but Bokashi handles these well)
“Brown” Materials (Carbon-Rich) – Often Found Around the House or Yard
These are drier materials that provide carbon. You’ll need to add these to keep your compost pile from getting too wet and smelly.
- Dry leaves
- Shredded newspaper (avoid glossy paper)
- Cardboard (torn into small pieces)
- Paper towels and napkins (unsoiled by grease or harsh chemicals)
- Sawdust (from untreated wood)
- Straw or hay
- Small twigs and yard trimmings (if you have them)
What to AVOID in Your Kitchen Compost (for most methods):
Some things can cause problems, like odors, pests, or pathogens. Always check your specific composting method’s guidelines, but generally avoid:
- Meat, fish, and bones (can attract pests and create odors)
- Dairy products (same reasons as meat)
- Oily or greasy foods (can create anaerobic conditions and odors)
- Diseased plants (to avoid spreading disease)
- Weeds that have gone to seed (unless you have a very hot compost system)
- Pet waste (cat or dog feces can contain pathogens)
- Chemically treated yard waste
- Coal or charcoal ash
Exception for Bokashi: As mentioned, Bokashi is different and can handle meat, dairy, and oils. Always follow specific Bokashi instructions.
Kitchen Composting Step-by-Step: The Process
Let’s get down to business! Here’s how to set up and manage your kitchen compost, focusing on a common outdoor bin method, but principles apply to others.
Step 1: Choose Your Composting Method and Location
Decide if you’re using a countertop bin, a larger outdoor bin, or a worm farm. If using an outdoor bin, pick a spot that’s:
- Convenient to your kitchen and garden.
- Level and has good drainage.
- Partially sunny (too much sun can dry it out, too much shade can keep it too wet).
- Accessible for turning and harvesting.
Step 2: Start Collecting Your Kitchen Scraps
Keep a container (a small bucket, an old ice cream tub, or a dedicated countertop bin) in your kitchen. As you cook or prepare meals, toss in eligible scraps. Having a lid helps contain any minor odors.
Step 3: Layer Your Compost Bin
This is where the magic begins. Think of building it like a cake, alternating layers of greens and browns:
- Base Layer: Start with a layer of coarse browns, like small twigs or straw, to help with aeration.
- Alternate Layers: Add a layer of moist kitchen scraps (greens), followed by a thicker layer of dry brown materials. For example, a few inches of vegetable peels, then a good shovelful of dry leaves or shredded paper.
- Moisture Check: Aim for the consistency of a wrung-out sponge. Too wet? Add more browns. Too dry? Add some water.
- Bury Kitchen Scraps: Always try to cover fresh kitchen scraps with a layer of browns. This is one of the best ways to prevent odors and deter pests.
Step 4: Maintain Your Compost Pile
Composting requires a little attention to thrive:
- Add Materials Regularly: Continue adding your kitchen scraps and, crucially, plenty of brown materials. A good ratio is roughly 2-3 parts browns to 1 part greens by volume.
- Turn the Pile (for outdoor bins): This is essential for aeration, which speeds up decomposition and prevents anaerobic (stinky) conditions. Aim to turn your pile every 1-2 weeks using a pitchfork or compost aerator. You want to mix the outer layers into the middle and vice versa. If you don’t have an outdoor bin designed for easy turning, you might skip this step or turn less often – it will just take longer.
- Monitor Moisture: Check the moisture level regularly. Squeeze a handful of compost: a few drops of water should come out. If it’s dry, sprinkle with water. If it’s soggy, add more browns and turn it.
- Temperature: An active compost pile will heat up in the center (130-160°F or 55-70°C). This heat is good – it kills weed seeds and pathogens. You don’t need to worry about this too much for a simple backyard pile; nature will handle it, but it means faster decomposition.
Step 5: Know When It’s Ready
Finished compost is dark, crumbly, and smells earthy – like a forest floor. You shouldn’t be able to identify the original food scraps. This can take anywhere from 2 months to a year, depending on your method, how often you turn it, and your climate.
Step 6: Harvest and Use Your Compost
Once it’s ready, you can harvest it. You can either:
- Sift it: Use a sieve or an old screen door to separate finished compost from larger, undecomposed materials. Toss the larger bits back into the active bin.
- Extract from the bottom: Many bins have access doors at the bottom to remove the finished compost while new material is added to the top.
Use your homemade compost to enrich your garden beds, potted plants, or lawns. Mix it into the soil or use it as a top dressing.
Composting Methods at a Glance
Here’s a quick look at how different methods stack up, so you can pick what’s best for you. Remember, there’s no single “right” way, just the way that works for your lifestyle!
| Method | Space Needed | Ease of Use | Speed of Composting | What It Processes | Potential Downsides |
|---|---|---|---|---|---|
| Countertop Bin (for collection) | Minimal (kitchen counter) | Very Easy | N/A (collects only) | Most kitchen scraps | Needs to be emptied regularly |
| Outdoor Compost Bin (tumbler or pile) | Medium to Large (yard) | Moderate (requires turning) | Medium (months) | Kitchen scraps, yard waste | Can attract pests if not managed properly; requires space |
| Worm Composter (Vermicomposting) | Small to Medium (indoors or outdoors) | Easy (once set up) | Fast (weeks to months) | Kitchen scraps (no meat/dairy/oils usually) | Requires specific care for worms; initial setup |
| Bokashi Fermentation Bin | Small (indoors) | Easy | Fast (collection phase); Medium (finishing phase) | All food scraps (incl. meat, dairy, oils) | Finished product needs further composting/burying; requires bran |
| Sub-podding / Trench Composting | Minimal (small garden areas) | Easy | Slow (months to a year) | Kitchen scraps | Needs direct soil contact; less refined product |
Troubleshooting Common Kitchen Composting Hiccups
Even with the best intentions, sometimes issues pop up. Here’s how to fix them:
Problem: It Smells Bad!
Cause: Usually too wet or not enough air, leading to anaerobic decomposition. Might also be too many “greens” or prohibited items like meat/dairy.
Solution:
- Add more dry brown materials (leaves, shredded paper, cardboard).
- Turn the pile to aerate it.
- Ensure you are not adding meat, dairy, or oily foods (unless using Bokashi).
- If using a bin with a lid, make sure it’s not sealed too tightly, allowing some airflow.
Problem: It’s Not Breaking Down / Too Dry
Cause: Lack of moisture or a lack of active microbes/organisms.
Solution:
- Add water and mix it in. The compost should feel like a damp sponge.
- Add some finished compost from another source, or a shovel full of garden soil. This introduces beneficial microbes.
- Ensure you have a good mix of greens and browns.
- If it’s an outdoor bin, check if it’s getting too much sun and drying out.
Problem: Pests (Flies, Rodents, etc.)
Cause: Exposed food scraps, or the presence of meat, dairy, and greasy foods.
Solution:
- Always bury fresh kitchen scraps under a layer of brown material.
- Avoid adding prohibited items like meat, dairy, and oily foods to standard compost piles.
- Ensure your bin has a secure lid if pests are a major concern.
- A tumbler bin can help deter some pests. For serious rodent issues, consider a robust metal bin or a worm farm set up indoors.
Problem: Too Much Fruit Fly Activity
Cause: Exposed fruit scraps are a magnet for fruit flies.
Solution:
- Again, the key is burying fresh fruit scraps under browns immediately.
- Keep your kitchen collection bin covered.
- You can create a simple trap: a jar with a bit of apple cider vinegar, a drop of dish soap, and a paper cone.
Gardening with Your Homemade Compost
Once you’ve successfully made your first batch of compost, it’s time to enjoy the fruits of your labor! This nutrient-rich material is incredibly beneficial for your plants.
- In Flower Beds and Vegetable Gardens: Spread a layer of compost 2-4 inches deep and gently mix it into the top 6-8 inches of soil. This improves soil structure, drainage, and fertility.
- Around Established Plants: Apply a 1-2 inch layer of compost around the base of trees, shrubs, and perennials, keeping it a few inches away from the main stem. This acts as a mulch, conserves moisture, and feeds the soil.
- In Container Plants: Mix compost into your potting soil at a ratio of about 1 part compost to 3-4 parts potting mix. This provides nutrients and improves water retention for potted plants.
- For Lawns: Rake a thin layer of compost (about 1/2 inch) over your lawn, especially new seed lawns or struggling areas. It helps build healthy soil underneath the grass.
Using compost is one of the best things you can do for your garden’s long-term health and productivity.
