The 600 square feet of soil production
There’s a renter in a 600 square foot Brooklyn apartment who composts every kitchen scrap her household produces, year-round, with zero smell, no flies, no neighbor complaints. She uses a combination of a bokashi bin under the sink and worm bin in a closet. The bokashi handles cooked food and meat scraps; the worms handle most of the raw vegetable matter. Once a month she takes finished compost down to the building’s community garden bed two blocks away. Her trash output (the thing she actually has to take to the curb) has dropped about 40% by volume.
Apartment composting gets dismissed as either impossible (no yard!) or smelly (the stereotype of a wormy bucket in a closet). Neither is true. Five methods work in small spaces. Smell management is largely about technique, not technology. Here’s how to pick the right method and execute it without your roommate hating you.
Why bother in an apartment
Food waste in landfills decomposes anaerobically and produces methane — a greenhouse gas about 80x more potent than CO2 over a 20-year window. Composting that same waste aerobically produces mostly CO2 and water, plus useful soil amendment. The EPA estimates 30–40% of US municipal solid waste is food and yard waste; reducing the food fraction has meaningful climate impact even per household.
You also get usable compost or worm castings for your houseplants, balcony pots, or community garden. The math: a typical household generates 200–400 lbs of compostable kitchen waste annually. That’s a serious quantity of soil amendment.
Method 1: Bokashi (anaerobic, sealed)
What it is: A Japanese fermentation method using a 5-gallon sealed bucket and “bokashi bran” inoculated with effective microorganisms (EMs). You layer food scraps with bokashi bran, press out air, seal. Fermentation happens in 2–4 weeks.
Pros:
- Composts everything: vegetables, cooked food, meat, dairy, citrus, onion (these defeat most other methods)
- No smell when sealed (it’s fermentation, not rotting)
- Fast: 2–4 weeks
- Small footprint: bucket under sink
Cons:
- Output is fermented (pickled-smelling) pre-compost, not finished compost; needs to bury in soil or add to another compost pile to finish
- Requires buying bokashi bran ongoing ($15–30 per 2.2 lb bag, lasts months)
- Acidic juice (drained periodically) needs disposal (great fertilizer when diluted 1:100 with water)
Best for: Apartments without outdoor space, households eating meat / dairy, anyone wanting fastest possible turnaround.
Method 2: Vermicomposting (worm bin)
What it is: Red wiggler worms (Eisenia fetida) in a ventilated plastic or wooden bin eating your kitchen scraps and producing worm castings (the highest-quality compost on Earth). Bins can be DIY (two stacked plastic totes with holes drilled) or commercial (Worm Factory, Hungry Bin, Subpod, Urbalive).
Pros:
- No smell when balanced correctly (smells like fresh soil, if anything)
- Worm castings are exceptional fertilizer
- Worms reproduce; you only buy them once (~$30 for a starter pound)
- Quiet, hidden, set-and-forget once running
Cons:
- Slower: 3–6 months for full bin turnover
- Can’t handle: meat, dairy, citrus, onion, oily food
- Worms die if you over- or under-feed, let the bin dry out, or let it freeze
- Squeamishness factor: there are worms in your house
Best for: Households comfortable with worms, vegetarian or mostly-vegetable scrap streams, gardeners who want premium fertilizer.
Method 3: Counter-top electric composters
What it is: Appliances like Lomi, Mill, FoodCycler, Vitamix FoodCycler. Heat and grind food waste into dehydrated powder in 4–24 hours.
Pros:
- Fastest: hours, not weeks
- Truly no smell (sealed unit with carbon filters)
- Handles meat, dairy, bones (mostly)
- Reduces volume 80–90%
Cons:
- Expensive: $300–500 upfront, plus carbon filter replacements ($30–60/year)
- Uses electricity (modest, but real)
- Output is dehydrated food powder, not actual compost — still needs to be added to soil for microbial breakdown
- The “instant compost” marketing is misleading; you have pre-compost
Best for: People who want compost-without-thinking and don’t mind the upfront and ongoing cost. Households with no outdoor option and no garden to use the output.
Method 4: Frozen scraps + community drop-off
What it is: Store kitchen scraps in a freezer bag or container; bring to a local composting facility, farmers market, or city food-waste drop-off.
Pros:
- Zero smell (it’s frozen)
- Zero setup cost
- Handles anything (frozen meat scraps don’t even matter)
- Available in most US cities (NYC, SF, Seattle, Portland, Denver have municipal programs)
Cons:
- Requires freezer space (not everyone has it)
- Requires a drop-off location within reasonable distance
- You don’t get the compost back
- Vulnerable to municipal program changes
Best for: Renters in cities with good drop-off infrastructure who don’t want to maintain a system at home.
Method 5: Balcony tumbler or sub-pod
What it is: A small outdoor tumbler composter on a balcony, or a Subpod-style in-ground container if you have access to even a small patch of soil (community garden, building shared garden).
Pros:
- Traditional aerobic composting; finished compost in 2–3 months
- Handles vegetables, grass clippings, yard trimmings
- No worms required
- Reasonable cost: $80–200 for a small tumbler
Cons:
- Requires balcony space or shared garden access
- Smells worse than other methods if not balanced (green:brown ratio matters)
- Pauses in winter (freezing slows decomposition)
- Limited size; fills up quickly
Best for: Renters with balconies; condos with shared outdoor space.
Which method matches which situation
- Studio apartment, meat-eater, indoor only, want speed: Bokashi
- 1BR with garden / community garden access: Vermicomposting
- $300 budget, want set-and-forget, no garden: Counter-top electric
- NYC apartment with farmers-market access: Frozen + drop-off
- Apartment with balcony or shared garden: Tumbler or Subpod
Smell management (the universal rules)
Any composting method can smell if mismanaged. Three rules that handle 95% of smell issues:
- Green:brown ratio. Food scraps are “green” (nitrogen-rich). Mix with “brown” (carbon-rich: dried leaves, shredded paper, cardboard) at roughly 1:2 by volume. Too much green smells; too much brown stalls.
- Aeration. Aerobic composting (everything except bokashi) needs air. Turn or aerate weekly.
- Moisture. Should feel like a wrung-out sponge. Too wet smells; too dry stalls.
FAQs
Will the apartment smell?
Not if you pick the right method and follow the basic rules. The bokashi bin and worm bin in the Brooklyn apartment example have zero perceptible smell.
Will I get fruit flies?
Possible if scraps sit too long before going to the bin. Keep a small lidded container on the counter; empty it daily into your composting system. Cover food in the bin completely with brown material (or seal in bokashi).
Can I compost meat?
Yes with bokashi or counter-top electric. No with worms or open tumbler.
What do I do with the finished compost if I don’t have a garden?
Houseplant pots benefit massively. Community gardens often accept donations. Friends with gardens. Some cities have municipal “compost give-back” programs.
How much compost will I produce?
Typical household: 50–150 lbs of finished compost per year. Less than your scraps because composting reduces volume significantly.
Does this work in winter in cold climates?
Indoor methods (bokashi, worms, electric) work year-round. Outdoor methods slow or stop in deep freeze. Frozen scrap + drop-off works year-round.
The landing
The Brooklyn apartment composter takes about 5 minutes a week of attention to her two systems. She reduces her trash output, produces compost for her plants and the community garden, and adds zero smell to a 600 square foot apartment. Composting in small spaces isn’t aspirational; it’s practical, well-documented, and depends entirely on choosing the right method for your specific situation. Pick one. Start small. The food scraps were going somewhere anyway. Better they go into soil than into a methane factory.
