Beginner’s Guide to Composting in Small Apartments
No backyard? No problem. You can compost in a studio, high-rise, or shared flat with the right setup. This guide walks you through odor-free methods, compact bins, and how to turn food scraps into soil—even if you live on the 12th floor
Why compost in an apartment?
Composting reduces landfill waste, lowers methane emissions, and creates nutrient-rich soil. Even in small apartments, you can divert banana peels, coffee grounds, and veggie scraps from the trash. It’s eco-friendly, satisfying, and surprisingly low-maintenance once you get the hang of it.
What you’ll need to start
- Compost bin: Countertop, under-sink, or balcony-safe. Choose based on method and space.
- Carbon source: Shredded paper, cardboard, dry leaves to balance food scraps.
- Airflow: Vents or manual stirring to prevent anaerobic rot.
- Moisture control: Compost should feel like a wrung-out sponge.
- Patience: Composting is a slow but rewarding process.
Method 1: Vermicomposting (worm bins)
Vermicomposting uses red wigglers to break down food scraps. It’s odorless, compact, and perfect for indoor use.
- Get a bin: Plastic or wood with air holes. Add bedding (shredded paper, coconut coir).
- Add worms: Red wigglers (Eisenia fetida) thrive in bins.
- Feed weekly: Small amounts of chopped veggie scraps, coffee grounds, and fruit peels.
- Harvest compost: Every 2–3 months, separate worms and use the finished castings.
Method 2: Bokashi (fermentation)
Bokashi is an anaerobic method using bran inoculated with microbes. It ferments food scraps in a sealed bin.
- Bin: Airtight with a spigot for draining liquid.
- Process: Layer scraps with Bokashi bran. Press down to remove air.
- Ferment: Let sit for 2 weeks. Drain “Bokashi tea” and dilute for plants.
- Finish: Bury fermented mix in soil or add to a second bin to complete decomposition.
Method 3: Electric composters
Electric units grind, heat, and dry food scraps into soil-like material in hours. They’re odor-free and ideal for tech-savvy renters.
- Brands: Lomi, Vitamix FoodCycler, Reencle.
- Process: Add scraps, press start. Output is dry, crumbly compost.
- Pros: Fast, clean, minimal effort.
- Cons: Expensive upfront, uses electricity.
What not to compost indoors
Managing odor and pests
Indoor composting should never stink. If it does, something’s off.
- Balance greens and browns: Equal parts food scraps and dry material.
- Stir or aerate: Oxygen prevents anaerobic rot.
- Drain excess liquid: Especially in Bokashi bins.
- Freeze scraps: Until ready to add, prevents fruit flies.
Where to use finished compost
- Houseplants: Mix into potting soil for nutrients.
- Balcony gardens: Feed herbs, tomatoes, and flowers.
- Community gardens: Donate excess compost locally.
- Friends: Share with gardeners or plant lovers.
FAQ
Can I compost in a studio apartment?
Yes. Vermicomposting and Bokashi bins are compact and odor-free if managed properly.
How long does composting take?
Vermicomposting takes 2–3 months. Bokashi ferments in 2 weeks, then needs soil time. Electric units finish in hours.
Do I need to stir the compost?
Yes, unless using Bokashi or electric units. Stirring adds oxygen and speeds decomposition.
Will it smell bad?
No, if balanced correctly. Bad smells mean too much moisture or not enough airflow.
Can I compost citrus and onions?
Yes, in moderation. Worms dislike acidic scraps, so limit citrus in vermicomposting.
