Composting is a sustainable way to recycle kitchen scraps and create nutrient-rich soil, but what if you don’t have a backyard or outdoor space? The good news is you can compost indoors too! Whether you live in an apartment or simply want to keep your composting efforts within reach, there are several methods for composting indoors without creating unpleasant odors. Here are the 8 best ways to compost indoors.
1. Vermicomposting (Worm Composting)
What it is: Vermicomposting involves using worms (usually red wigglers) to break down organic matter into rich compost. The worms consume food scraps and produce nutrient-dense castings that are excellent for your plants.
- How it helps: Worms are efficient decomposers, and the process is odor-free if maintained correctly.
- Tip: Use a worm bin with proper drainage and airflow. Keep the bin in a cool, dark location, and avoid overfeeding the worms to prevent odors.
2. Bokashi Composting
What it is: Bokashi composting is a method of fermenting kitchen waste using a special inoculant (Bokashi bran) that contains microorganisms. The waste is fermented anaerobically, meaning it doesn’t require oxygen to break down.
- How it helps: This process breaks down all types of organic waste, including dairy, meat, and cooked food, which are typically not composted in other systems. It’s quick and can be done indoors without odor if properly maintained.
- Tip: Use a Bokashi bin, which includes a tight-sealing lid and a drainage system for excess liquid. Once the fermentation process is complete, bury the fermented waste in soil for further decomposition.
3. Countertop Composting Bins
What it is: A simple solution for small kitchens, countertop composting bins are compact, easy to use, and typically feature charcoal filters to reduce odors.
- How it helps: These bins are great for collecting food scraps until they can be transferred to a larger composting system, like a garden compost pile or outdoor composting bin.
- Tip: Empty the countertop bin regularly, and use compostable liners for easy cleanup. Make sure to add a balance of green (nitrogen) and brown (carbon) materials to avoid odors.
4. Electric Composters
What it is: Electric composters are high-tech machines that break down food scraps quickly using heat and aeration. They’re compact and can fit into a kitchen or pantry, providing an efficient way to compost indoors.
- How it helps: These composters are fast and odor-free, converting kitchen waste into compost or soil additive in as little as 3-4 hours.
- Tip: While convenient, electric composters use electricity, so they may not be as energy-efficient as other methods. Follow the manufacturer’s instructions for optimal results.
5. Indoor Composting with a Kitchen Digestor
What it is: Kitchen digesters are similar to electric composters but often focus on processing food scraps with natural microorganisms and enzymes. They are perfect for those who want a more natural, low-maintenance solution without the need for constant monitoring.
- How it helps: These machines break down food waste and turn it into compost quickly, without odors. They are typically smaller and designed for use in homes with limited space.
- Tip: Regularly maintain the digestor to avoid blockages and ensure proper functioning. Most models can handle most food scraps, including fruit and vegetable peels, coffee grounds, and eggshells.
6. Tumbler Bins (Small Indoor Versions)
What it is: A tumbler compost bin is a sealed, rotating bin that allows you to mix and aerate the compost easily. Smaller indoor versions of tumbler bins are designed for apartment use.
- How it helps: Tumbler bins are self-contained, meaning odors are minimized when used correctly. The rotation helps mix materials and speed up decomposition.
- Tip: Make sure to keep the tumbler in a well-ventilated area, and monitor moisture levels to avoid a wet, smelly pile. Aim to turn the bin every few days.
7. DIY Indoor Composting Systems (Using Plastic Bins)
What it is: Creating a DIY composting system with plastic bins is an affordable way to compost indoors. You can use multiple bins—one for fresh scraps and another for the finished compost. Proper ventilation is key to avoiding odors.
- How it helps: This system can handle a large amount of waste, and you can control the conditions like temperature and moisture.
- Tip: Drill holes in the bins to ensure proper airflow. Start with a layer of brown materials (shredded paper, leaves) at the bottom to help absorb excess moisture. Keep the bins in a cool, dry area, and turn the materials occasionally.
8. Use of Compostable Bags for Storage
What it is: If you’re not ready to compost right away, you can store your food scraps in compostable bags to avoid mess and odor. These bags are biodegradable and can be placed in your compost bin when you’re ready.
- How it helps: Compostable bags allow you to keep your kitchen clean and smell-free while you collect organic waste for future composting.
- Tip: Make sure the bags are placed in a cool, dry place and empty them into your composting system as soon as possible to prevent odors.
Conclusion
Composting indoors is not only environmentally friendly but also helps you reduce waste and enrich your garden soil. Whether you opt for a worm composting bin, Bokashi system, or countertop composting, there are plenty of ways to compost in small spaces without the hassle of odors or mess. With the right tools and maintenance, you can create nutrient-rich compost year-round, even in an apartment.
