The Benefits of Indoor Composting in Small Spaces
Indoor composting offers apartment dwellers multiple advantages beyond just waste reduction. You’ll create nutrient-rich soil for houseplants while significantly decreasing your household waste—up to 30% less trash heading to landfills. The process also eliminates the methane emissions typically produced when organic waste decomposes in landfills, shrinking your carbon footprint even from a small space.
Indoor composting systems take up minimal room—many units require just one square foot of space under your sink or in a closet. You’ll save money on potting soil and plant fertilizers while enjoying the satisfaction of completing the natural growth cycle within your own home. Some apartment gardeners report saving $50-100 annually on plant care products by using their homemade compost.
Additionally, properly maintained indoor composting systems are odorless and pest-free, making them perfect for apartment living where close quarters demand cleanliness. The convenience of having a compost bin right in your kitchen also makes sustainable living more accessible—no more storing scraps in the freezer until your next trip to a community compost site.
1. Vermicomposting: Using Worms to Transform Kitchen Waste
Compost food waste efficiently with the VermiHut Plus worm composter. This five-tray system features enhanced airflow and odor control for optimal vermicomposting, plus includes accessories to get you started.
Vermicomposting harnesses the power of worms to convert kitchen scraps into nutrient-rich castings that plants love. This technique is perfect for apartment dwellers due to its compact nature and efficiency.
Setting Up Your First Worm Bin
To create a worm bin, you’ll need a plastic container with a lid, bedding materials like shredded newspaper, and red wiggler worms. Drill air holes in the lid and sides, add moistened bedding, then introduce your worms. Place the bin in a cool, dark spot like under your sink or in a closet for optimal performance.
Best Worm Species for Apartment Composting
Red wigglers (Eisenia fetida) are the ideal species for indoor vermicomposting due to their voracious appetite and ability to thrive in confined spaces. Unlike common earthworms, these surface-dwellers process food scraps quickly, reproducing rapidly in temperatures between 55-75°F. Dendrobaena veneta (European nightcrawlers) offer a good alternative for slightly larger systems.
2. Bokashi Composting: The Fermentation Method
Bokashi composting uses beneficial microorganisms to ferment food waste through an anaerobic process. Unlike traditional composting, bokashi can handle all food scraps including meat, dairy, and oily foods—making it perfect for apartments with diverse kitchen waste.
Creating Your Bokashi System
To set up your bokashi system, you’ll need two airtight buckets with spigots, bokashi bran, and a spray bottle. Layer your food scraps and sprinkle bokashi bran between each layer, pressing down to remove air pockets. Once full, seal the bucket and let it ferment for 2 weeks. The airtight environment prevents odors from escaping, making this ideal for apartment living.
Managing Bokashi Leachate
Drain the bokashi leachate (liquid byproduct) every 2-3 days through the spigot. Dilute this nutrient-rich liquid at a 1:100 ratio with water to create an excellent fertilizer for houseplants. For kitchen drains, pour undiluted leachate to prevent clogs and eliminate odors. Proper leachate management is crucial to prevent unpleasant smells in your apartment kitchen.

Compost crocks with charcoal filters and freezing scraps until processing are excellent collection methods that prevent odors. With proper maintenance and appropriate system selection, apartment composting can be completely odor-free.
How much space do I need for indoor composting?
Most indoor composting systems require minimal space. Compact worm bins, bokashi systems, and countertop electric composters can fit under a sink or in a kitchen corner. A typical soil-based system measures only 12-16 inches in diameter. For ultra-small spaces, mason jar composting uses just a quart-sized container. Even the smallest apartments can accommodate some form of composting system.
What can I compost in an apartment?
In apartment composting systems, you can process fruit and vegetable scraps, coffee grounds, tea bags, eggshells, and plant trimmings. Bokashi systems can additionally handle meat, dairy, and cooked foods that traditional methods can’t. Electric composters process almost all food waste. Avoid adding large amounts of citrus or onions to worm bins, as these can be problematic for the worms.
How do worm bins work for apartment composting?
Worm bins use red wiggler worms to transform kitchen scraps into nutrient-rich castings. The system consists of a plastic container with bedding (shredded paper, cardboard, or coconut coir), and the worms. The worms consume the food waste and produce castings (worm poop) that serve as an excellent fertilizer. These bins require minimal maintenance and can process about 1-3 pounds of kitchen waste weekly.
Is bokashi composting suitable for apartments?
Bokashi composting is ideal for apartments because it uses anaerobic fermentation in sealed containers, preventing odors and pests. This method can process all food waste, including meat and dairy, which traditional composting cannot. The system consists of an airtight bucket and bokashi bran (inoculated with beneficial microorganisms). The fermented material must eventually be buried in soil or added to another composting system.
