As an Amazon Associate we earn from qualifying purchases. Details

The best way to start a compost bin is to pair a small kitchen caddy with an outdoor bin that fits your space and yard waste. This guide helps you decide which starter setup makes sense for an apartment, a small patio, a raised-bed garden, or a full backyard. You will learn what matters when you start, see six bins that suit different situations, and follow simple steps to add your first layers. It also covers the best way to start a compost pile, the best way to make a compost bin work in a small space, and the best way to start compost pile habits you can keep. No special skills are needed, only food scraps, dry leaves, water, and airflow.

Quick answer

Start with two parts: a 1.3-gallon to 1.75-gallon countertop caddy for daily scraps, plus an outdoor bin for bulk composting. If you have a yard, an expandable outdoor bin or a dual-chamber tumbler gives you room for leaves and food scraps together. If you garden in raised beds, an in-ground worm bin lets you compost right where plants grow. For apartments without outdoor space, a countertop caddy collects scraps for a municipal green bin, drop-off site, or shared garden bin. Check the listing for capacity, dimensions, materials, and what is included before you buy. You can compost at home using food scraps from your kitchen and dry leaves and woody material from your yard.

What matters when you start a compost bin

The best starter depends on space, volume, and how often you want to empty scraps. These five points shape the choice.

1. Where the finished compost will happen

A countertop bin does not make finished compost by itself. It holds scraps for a day or two. You still need an outdoor bin, worm bin, tumbler, or collection program. If you have a backyard, choose an outdoor bin with 37 gallons or more. The listing for the outdoor expandable option states capacity as 216 gallons in specs and expandable to 3.75 feet (237 gallon) in bullets. That conflict means you should check the product listing for current capacity before planning space. The dual-chamber tumbler lists Capacity as 37 gallons, which suits steady garden output.

2. Kitchen capacity and emptying rhythm

Most countertop picks hold 1.3 gallons. One lists 4.92 liters, another lists 5 liters, and another lists 6.62 liters. A larger 6.62 liters caddy needs fewer trips to the outdoor bin. A smaller 0.65 gallons in-ground unit is not a kitchen caddy at all. Match caddy size to how much you cook. If you chop vegetables daily, a 1.3 gallons model emptied every two to three days stays fresher. If you cook rarely, a smaller caddy still works, but empty it at least weekly. The Epica listing advises to empty and clean weekly for best results.

3. Airflow, lid design, and odor control

Airflow prevents soggy scraps. Sealed lids and charcoal filters reduce kitchen odors. Ventilated designs reduce moisture when used a certain way. The first countertop pick states ventilation helps when compostable bags are used without the inner bucket. The stainless picks use replaceable activated-charcoal filters. The filter-free pick uses a secure, well-fitted lid with no filters to replace. Outdoor bins need vents too. The expandable outdoor bin lists Excellent ventilation, while the tumbler relies on rotation every few days. Pick a system you will actually aerate.

4. Materials, cleaning, and durability

Stainless steel resists rust and wipes clean. Plastic is light and often has a smooth interior. Metal with a plastic inner pail keeps scraps away from the outer shell. Check cleaning limits. One lid and bucket set is hand-washable and not dishwasher safe. Another plastic set lists dishwasher safe construction. One stainless model uses a one-piece molded design that resists rust and leaks. If low maintenance matters, smooth interiors and removable inner buckets save time. If you want a long outdoor life, look at frame and wall material in the listing.

5. Footprint and garden fit

Measure your spot. A 7.16″L x 7.16″W x 11″H caddy fits a narrow counter. An 8.3″L x 10.15″W x 12″H oval needs more height under cabinets. A 10.63″L x 9.88″W x 9.38″H rectangular model needs counter depth. Outdoors, a 25″L x 23.5″W x 29.5″H tumbler needs swing room to rotate. An in-ground unit at 4.3″L x 4.3″W x 10″H fits inside a raised bed. For renters, a countertop caddy plus drop-off works without yard changes. For homeowners, an outdoor bin near the garden shortens carrying trips.

Picks that fit different ways to start

Each write-up below covers what it is, who it fits, and its limits. Specs come from the product listings.

Expandable outdoor bin for yard leaves and scraps

This is an outdoor mesh-style bin for bulk composting. It suits homeowners who have leaves, grass clippings, and kitchen scraps and want a simple enclosure to start a pile. The listing states Material as Plastic and Color as Black. It states Item Weight as 7 pounds, so moving it for a new pile location is realistic. Bullets state Easy to assemble with closure keys and Excellent ventilation. That airflow helps wet kitchen scraps balance with dry leaves. The specs list Capacity as 216 gallons, while bullets say expandable to 3.75 feet (237 gallon). Since those figures differ, check the product listing for usable volume. Skip it if you have no outdoor space or need a sealed, pest-resistant tumbler.

Dual-chamber tumbler for continuous batches

This is a rotating outdoor composter with two chambers. It suits gardeners who want one side filling while the other side matures. The listing states Capacity as 37 gallons and describes 2×18.5 Gal/70L chambers. It states Product Dimensions as 25″L x 23.5″W x 29.5″H and Material as Alloy Steel. Bullets describe a strong galvanized steel base and tight seals to keep out unwanted pests. They also advise a few rotations every few days, which avoids hand turning with a fork. The shape is listed as Hexagonal, which helps mixing during rotation. Skip it if you cannot lift scraps to chamber height or lack room to spin the drum safely.

In-ground worm bin for raised beds

This is a small in-ground unit that works inside a planting bed. It suits raised-bed gardeners who want to feed scraps to worms near roots. The listing states Capacity as 0.65 gallons and Product Dimensions as 4.3″L x 4.3″W x 10″H. Bullets describe a built-in rotating date indicator on the lid and a detachable bottom cover for removing finished material. It is Designed specifically for raised beds, vegetable gardens, flower beds, and outdoor planting spaces. It encourages natural worm composting underground to reduce odors. Because 0.65 gallons is small, it will not handle all household scraps. Skip it if you need whole-house volume or do not have soil beds. Learn more about worms in best worms in my compost bin.

Stainless countertop bin with charcoal filter

This is a 1.3 gallons cylindrical kitchen caddy. It suits beginners who want a neat countertop collector for a future outdoor pile. The listing states Material as Stainless Steel and Product Dimensions as 7.16″L x 7.16″W x 11″H. Bullets describe an airtight lid and a replaceable activated-charcoal filter to help reduce odors. Each filter lasts 3–6 months with proper care. Bullets advise to Empty & clean weekly for best results. The tall, narrow shape saves counter depth. The listing does not state that compostable bags are included, so check the product listing if you want liners. Skip it if you want a wide opening for large melon rinds. See also best compost bin for kitchen counter.

Larger plastic countertop bin with stay-open lid

This is a 6.62 liters oval kitchen bin. It suits busy kitchens that fill a small 1.3 gallons caddy too fast. The listing states Capacity as 6.62 liters and Product Dimensions as 8.3″L x 10.15″W x 12″H. Bullets state Stay-open lid makes it easy to toss scraps in while you’re working and Lid is removable for convenient emptying. The Smooth interior makes Bin easy to clean. Oxygen can flow through the soft-close lid, which the listing links to odor-containing and pest-reducing function. That design differs from airtight models, so choose based on fruit-fly pressure in your kitchen. Skip it if counter height is tight, since 12″H needs clearance. Pair it with ideas in best make a compost bin at home.

Ventilated countertop bin with compostable bags

This is a 4.92 liters rectangular kitchen collector. It suits beginners who prefer bagged collection for cleaner trips to the outdoor bin. The listing states Capacity as 4.92 liters and Product Dimensions as 10.63″L x 9.88″W x 9.38″H. Bullets state Includes 12 plant-based compostable tear-off bags and Built-in hooks help keep bags securely in place during use. Ventilation design helps reduce moisture build-up when compostable bags are used without the inner bucket. The removable inner bucket lifts out for direct emptying. Cover and bucket are hand-washable and not dishwasher safe. Skip it if you do not want to buy refill bags, since refills are sold separately.

How to choose for your home

Use this sequence to avoid buying the wrong size.

Start with your scrap path. Where will full caddies go? Options include a backyard bin, tumbler, worm bin, municipal green cart, or community drop-off. If you have no outdoor outlet, do not buy a large outdoor bin yet. Start with a countertop caddy and confirm a drop-off accepts scraps.

Then match volume. A household that cooks most nights fills a 1.3 gallons caddy in two to four days. A 6.62 liters model stretches that by about one-third. An outdoor household bin should hold several weeks of mixed greens and browns. A 37 gallons tumbler suits small gardens. A large expandable backyard ring suits yards with fall leaves.

Then check daily habits. If odors bother you, favor airtight lids with charcoal filters and weekly emptying. If fruit flies appear, empty more often and rinse the caddy. If lifting is hard, favor a light 1.1 pounds plastic caddy and a ground-level outdoor bin over a raised tumbler. The Arkalis plastic model lists Item Weight as 1.1 pounds, which is easy to carry.

Look at cleaning. Removable inner buckets, smooth interiors, and wide openings reduce scrubbing. Confirm hand-wash versus dishwasher guidance in the listing. Do not assume all stainless or plastic parts allow machine washing.

Finally, plan placement. Keep the caddy near prep space, not across the kitchen. Outdoors, place the bin on bare soil where water drains, with room to turn, water, and add leaves. Tumblers need rotation clearance. In-ground worm units need open soil inside a bed. If you are making a bin from salvaged materials, compare approaches in best compost bin how to build and best making a compost bin from a trash can.

Starter planning example

This worked example shows how much room a first month of scraps might need. It uses a hypothetical household so you can compare bins.

Our planning estimate setup

Assume two people cook five nights per week. Assume they collect 0.4 gallons of scraps per cooking day. Assume they empty the kitchen caddy into an outdoor bin twice per week. Assume four weeks per month. These are our planning estimate inputs, not measured results.

Step 1: Weekly scraps. Multiply cooking days by daily volume. 5 x 0.4 gallons = 2.0 gallons per week. Re-check: 5 x 0.4 = 2.0. Correct.

Step 2: Monthly scraps. Multiply weekly volume by weeks. 2.0 gallons x 4 = 8.0 gallons per month. Re-check: 2 x 4 = 8. Correct.

Step 3: Caddy loads. Divide weekly scraps by caddy size for a 1.3 gallons model. 2.0 / 1.3 = 1.54 loads per week. Re-check: 1.3 x 1.5 = 1.95, remainder 0.05, so 1.54 is correct. That means about three fills every two weeks.

Step 4: Larger caddy loads. Use 6.62 liters, which converts to about 1.75 gallons. 2.0 / 1.75 = 1.14 loads per week. Re-check: 1.75 x 1.14 = 1.995, correct. That saves roughly one emptying trip every two to three weeks.

Step 5: Outdoor room. Add dry leaves at roughly equal volume to food scraps for balance. 8.0 gallons scraps + 8.0 gallons leaves = 16.0 gallons for one month before settling. Re-check: 8 + 8 = 16. Correct.

What this changes: a 37 gallons tumbler holds about two months of this mixed input, since 37 / 16 = 2.31 months. Re-check: 16 x 2.3 = 36.8, correct. A large expandable backyard bin holds many months more. A 0.65 gallons in-ground worm unit holds only part of one day, since 0.65 / 0.4 = 1.63 days. Re-check: 0.4 x 1.6 = 0.64, correct. So pair small worm units with another outlet. This kind of math also helps if you are reading best way to make a compost pile and sizing a pile footprint.

Composting reduces the volume of materials that might otherwise go to landfills or trash incinerators, and produces a free soil amendment that can reduce fertilizer and pesticide use. Compost also enables soil to absorb and hold water better, helping reduce erosion and flooding in heavy rains and retain water during droughts.

How to start in simple steps

You do not need activators or special soil to begin. Follow the manual for any bin you buy.

Pick a level, shady outdoor spot with drainage. Avoid low spots that stay wet. Keep the bin where you will actually carry scraps in rain and winter. For cold climates, read best starting a compost bin in winter.

Add browns first. Shredded dry leaves, straw, or torn cardboard make a 3-inch to 4-inch base. This lifts food off the ground and lets air enter. Save a bag of dry leaves beside the bin.

Add greens. Fruit and vegetable trimmings, coffee grounds, tea bags, and fresh yard trimmings count as nitrogen-rich inputs. Bury fresh food under browns to reduce flies and odors. The countertop listings mention fruits, vegetables, coffee grounds, tea bags, and egg shells as typical kitchen inputs.

Keep the mix damp like a wrung sponge. Water dry layers lightly. If it smells sour, add more browns and turn to add air. If nothing changes for weeks, chop inputs smaller and check moisture.

Turn or rotate. For piles, lift with a fork every one to two weeks. For tumblers, rotate a few times every few days per the listing guidance. For in-ground worm units, do not dig aggressively; let worms work and add small amounts often.

Harvest when dark and crumbly. Sift out large sticks and return them to the new batch. Use finished compost as a topdressing in beds. If you garden in raised beds, see best adding compost to raised garden bed.

5 common mistakes to avoid

Adding only food scraps. Wet food alone turns slimy. Keep a browns bag nearby and cover each food deposit. Browns include dry leaves and shredded cardboard.

Letting the kitchen caddy sit too long. Even with filters, old scraps attract flies. Empty every two to three days in warm weather. Rinse and air-dry the caddy before refilling.

Chopping nothing. Whole pumpkins and corn stalks stall airflow. Cut scraps to small pieces. Break boxes down before adding.

Drowning or drying the pile. Soggy piles smell. Dry piles stall. Check moisture weekly by squeezing a handful with gloves. Adjust with browns or water.

Choosing the wrong scale. A 0.65 gallons worm tube cannot take all scraps from a large family. A 216 gallons ring overwhelms a balcony. Match bin volume to space and cooking volume, and confirm dimensions in the listing. For small spaces, see best compost bin for small garden.

Buying scenarios

Small apartment with drop-off. Choose a 1.3 gallons stainless or plastic caddy with a good lid. Empty twice weekly into a sealed tote for drop-off. You do not need an outdoor bin. Line the caddy only with bags the program accepts.

Busy family kitchen with backyard. Choose a 6.62 liters or 4.92 liters caddy plus a 37 gallons tumbler or expandable yard bin. The larger caddy cuts trips. The outdoor bin handles leaves plus scraps. Keep a browns pile beside it.

Raised-bed gardener. Choose a 1.3 gallons caddy plus one or two 0.65 gallons in-ground worm units. Feed small amounts often. Keep the main surplus going to an outdoor bin or green cart. This spreads fertility without hauling compost.

FAQ

What is the best way to start a compost bin from nothing?

Start with a kitchen collector and an outdoor home for scraps. Add a base of dry leaves, then alternate food scraps with more leaves. Keep damp and aerated.

What is the best way to start a compost pile without a bin?

Mark a 3-foot square area on bare soil, pile browns first, then layer greens and browns. Cover fresh food with browns. Turn every one to two weeks. A bin simply keeps the pile neat and deters pests.

What is the best way to make a compost bin work faster?

Chop inputs small, keep moisture even, add enough browns, and aerate often. Tumblers that rotate every few days mix without forking. Do not overload a small worm unit and expect fast results.

What should I put in first?

Dry browns. Leaves, straw, or torn cardboard create airflow under wet food. Then add a small bucket of scraps and cover completely with more browns. Repeat as you collect.

How do I keep smells and flies down?

Empty the kitchen caddy often, bury food under browns outdoors, and avoid meat, dairy, and oils unless your program allows them. Charcoal filters help indoors. Ventilation and turning help outdoors. Rinse caddies weekly.

Can I start in winter or in a small garden?

Yes, but breakdown slows in cold. Keep adding, keep covered, and turn less often in freezing weather. In small gardens, use a compact tumbler or in-ground worm bin and send extra scraps to collection. Check winter tips in linked guides.

When is finished compost ready?

It looks dark, crumbly, and earthy, with few recognizable scraps. Sift out woody bits and return them to the bin. If it still looks like food, give it more time, moisture, and air.

Bottom line

If you have a yard with leaves, start with a kitchen caddy plus an expandable outdoor bin or 37 gallons dual tumbler. If you garden mainly in raised beds, add a small in-ground worm unit for direct feeding. If you have no outdoor space, start with a 1.3 gallons to 6.62 liters caddy and a drop-off plan. Choose the setup you will empty, water, and aerate, then check capacity, dimensions, and cleaning limits in the listing before you buy.
