Best Way to Make a Compost Pile: 6 Tools That Help

As an Amazon Associate we earn from qualifying purchases. Details

The best way to make a compost pile starts with a simple system you will actually use. You collect food scraps in the kitchen, add dry leaves and yard trim outside, keep air and moisture balanced, and turn or mix the pile over time. This guide helps you decide which type of container fits your space, how much room you need, and what to check before you buy.

You will compare outdoor bins and tumblers that hold the pile, countertop caddies that carry scraps, and a bacterial additive meant to support decomposition. Specs below come from the product listings. Check the listing for anything not stated.

Quick answer

If you want a large open pile, the expandable outdoor bin with a listed capacity of 216 gallons gives you the most room for leaves and scraps. If you want contained turning without hand digging, the dual-chamber tumbler with a listed capacity of 37 gallons and two 18.5 Gal chambers fits patios and small yards. For kitchens, a 1.3 gallons stainless caddy, a 1.75 Gal plastic bin, or a 4.92 liters ventilated caddy helps you carry scraps outside without mess. The 2.5 lb bacterial accelerator is sprinkled over the pile to support biological activity. Choose open volume for yard waste, contained turning for tidiness, and a small caddy for daily collection.

What to check before you build a compost pile

1. Where the pile will live

An outdoor pile needs ground space, air flow, and access for adding and removing material. A tumbler with listed dimensions of 25″L x 23.5″W x 29.5″H sits in one footprint. An expandable outdoor bin can open to 3.75 feet across. Measure your spot and leave walking room on at least one side. If you rent or have a patio, a closed tumbler keeps material contained. If you have leaves and room, an open bin holds more bulk.

2. How much volume you can fill

Pile size controls what you can compost at home. The listings in this guide state 216 gallons, 37 gallons, 6.62 liters, 4.92 liters, 1.3 gallons, and 1 gallons. Larger outdoor volume suits fall leaves and yard trim. Smaller kitchen volume suits daily food scraps that you carry outside every few days. Match the outdoor container to your yard waste and the indoor caddy to your cooking habits. You can compost at home using food scraps from your kitchen and dry leaves and woody material from your yard.

3. Air, moisture, and mixing

Compost needs oxygen and even moisture. Look for ventilation, a lid that manages air, and a way to turn material. The expandable bin listing states excellent ventilation. The tumbler listing describes rotation every few days instead of hand mixing. One kitchen bin states oxygen can flow through the soft-close lid, while another uses ventilation when used with compostable bags without the inner bucket. If a listing does not state vent size or airflow rate, check the product listing and plan to turn the pile with a fork.

4. Materials and cleaning

Outdoor bins in this guide list Plastic and Alloy Steel. Kitchen caddies list Stainless Steel, Plastic, and Wheat Straw. Stainless resists rust and wipes clean. Plastic with a smooth interior rinses easier and shows residue less. Wheat straw will not rust or dent but needs hand washing. Check whether parts are hand-washable and whether bags or filters are included. The cover and bucket on one caddy are hand-washable and not dishwasher safe.

5. Odor control and pests

Airtight lids, charcoal filters, and tight seals help with kitchen odors. Two kitchen options include replaceable activated-charcoal filters. One includes 2x Activated Charcoal Filters and 20x Compostable Trash Bags. One includes 12 plant-based compostable tear-off bags that conform to ASTM D6400. Outdoors, tight seals and a locking base help keep unwanted pests out. No backyard system is pest-proof, so keep meat, dairy, and oils out unless the manufacturer’s manual says otherwise.

6. What you want from finished compost

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. If your goal is bagged compost for raised beds, pick outdoor volume that matches your beds. If you want to add compost to a raised garden bed, plan for steady output rather than one large batch.

Tools that support a compost pile

1. Large expandable outdoor bin for leaves and bulk

This pick is the open-air option for a true pile. The listing states a capacity of 216 gallons and describes expansion to 3.75 feet with 237 gallon in one bullet, so read both numbers and check the product listing for which measurement applies to the setup you plan. It lists Plastic in Black, an item weight of 7 pounds, and assembly with closure keys. The bullets also state excellent ventilation. That open wall design suits fall leaves, yard trim, and mixed kitchen scraps carried from inside.

Who it fits: homeowners with yard waste and room for a 3-foot-plus circle. You can add material from the top and lift the wall for access. For ideas on simple wood builds, see best diy compost bin out of pallets and best building a compost bin from pallets.

Who should skip it: skip if you need a closed, animal-resistant container or have only a balcony. The listing does not state a lid, lock, base, or pest rating. It also does not state food-safe or lead-free status.

2. Dual-chamber outdoor tumbler for contained turning

This pick suits gardeners who want to turn material with a handle-free spin. The listing states a capacity of 37 gallons in two 18.5 Gal chambers, each 70L, with product dimensions of 25″L x 23.5″W x 29.5″H. It lists Alloy Steel in Black and an item weight of 8 kg. Bullets describe 2 sliding doors, side-locking mechanisms, a galvanized steel base, and tight seals to keep out unwanted pests. The maker suggests a few rotations every few days.

Who it fits: small yards and patios where a neat, off-the-ground bin matters. Fill one side while the other side matures. To learn the routine, read best rotating compost bin how to use and best making compost in a tumbler.

Who should skip it: skip if you rake large volumes of leaves. Two 18.5 Gal chambers fill fast in fall. The listing does not state a weatherproof rating or assembly time.

3. Stainless countertop caddy with charcoal filter

This pick is a 1.3 gallons cylindrical kitchen collector. The listing states Material as Stainless Steel, color as silver, and dimensions of 7.16″L x 7.16″W x 11″H. Bullets describe an airtight leak-resistant lid and a replaceable activated charcoal filter to help reduce odors. Each filter lasts 3–6 months with proper care. The one-piece molded design resists rust and leaks and is meant for hand washing with warm water.

Who it fits: cooks who want a small, neat pail for daily peels and coffee grounds. Empty it into your outdoor pile weekly for best results, per the listing. For countertop choices, see best compost bin for kitchen counter.

Who should skip it: skip if you cook large volumes or want to line the pail with a bag. The listing does not state bag compatibility. One spec field lists item weight as 0.27 g, which looks like a listing error, so check the product listing and rely on the stated dimensions instead.

4. Large plastic kitchen bin with stay-open lid

This pick holds more scraps between trips outside. The listing states a capacity of 6.62 liters and product dimensions of 8.3″L x 10.15″W x 12″H. It lists Plastic in Charcoal with an oval shape and item weight of 0.74 kg. Bullets describe a stay-open lid for tossing scraps while you work, a removable lid for emptying, a smooth interior that is easy to clean, and a design that keeps bags tucked inside for a neat look.

Who it fits: busy kitchens that fill a small pail too fast. The wider oval mouth takes corn husks and melon rinds more easily than a narrow cylinder. Learn how to feed scraps into an outdoor system with best way to start a compost bin.

Who should skip it: skip if counter space is tight. At 12″H and over 10″W, it needs more room than 1-gallon caddies. The listing does not state that a filter or bags are included.

5. Ventilated countertop collector with bags included

This pick is built around drier scraps and simple emptying. The listing states a capacity of 4.92 liters, shape as Rectangular, and dimensions of 10.63″L x 9.88″W x 9.38″H. It lists Plastic in White and includes 12 Compost Genie compostable bags. Bullets state that ventilation design helps reduce moisture build-up when compostable bags are used without the inner bucket, and that bags conform to ASTM D6400. The removable inner bucket lifts out for emptying.

Who it fits: renters and small kitchens that want included bags and hooks that hold bags in place. Use it with or without the inner bucket per the listing. For other small-space paths, see best compost bin for small garden.

Who should skip it: skip if you want dishwasher-safe parts. The cover and bucket are hand-washable and not dishwasher safe. The listing does not state a charcoal filter.

6. Bacterial additive sprinkled over the pile

This pick is not a container. It is a 2.5 LBS box meant to support decomposition in an existing heap. The listing states an item weight of 2.6 pounds, size of 2.5 LBS, and included components as Roebic CA-1 Bacterial Compost Accelerator: 2.5 pounds, for faster composting. Bullets say to simply sprinkle over compost pile, that the formula is buffered to maintain pH levels, and that it is effective in wide temperature ranges. The maker frames it as boosting biological activity for nutrient-rich compost.

Who it fits: gardeners with a slow or cool pile heavy in leaves who want a simple add-and-wait step. It takes little storage space. For winter piles, pair it with seasonal tips in best starting a compost bin in winter.

Who should skip it: skip if you have not yet set up outdoor volume. Additive cannot replace air, water, and mixing. The listing does not state application rates, ingredient percentages, or safety certifications.

How to choose the best way to make a compost pile

Start with your outdoor volume first, then pick a kitchen caddy to feed it. If you rake leaves, favor the 216 gallons open bin. If you have a patio, favor the 37 gallons tumbler. If you cook daily, add a 1 gallons to 1.75 Gal caddy so scraps do not sit long.

Think in three buying scenarios. Suburban yard with trees: pair the large expandable bin with a stainless 1.3 gallons pail. You can dump leaves in fall and add kitchen scraps year-round. Small patio or rental: pair the dual-chamber tumbler with the ventilated 4.92 liters collector and included bags. Turning stays clean and compact. Apartment with no yard: use a countertop collector to gather scraps for a shared site, community garden, or green bin, and read best make a compost bin at home before you buy outdoor gear you cannot place.

Planning example: sizing trips from kitchen to pile

This worked example uses a hypothetical household to show how container size changes hauling. It is our planning estimate, not a composting rule.

Assume a household fills a 1.3 gallons kitchen caddy every 3 days. Assume the outdoor bin holds 216 gallons of loose material. Assume no settling or removal for this math.

Step 1: Find loads per outdoor bin. Divide outdoor volume by caddy volume. 216 / 1.3 = 166.1538, rounded to about 166 loads.

Step 2: Find days to fill from kitchen scraps alone. Multiply loads by days per load. 166 x 3 = 498 days.

Step 3: Re-verify. Check division: 1.3 x 166 = 215.8, which matches 216 gallons within rounding. Check multiplication: 166 x 3 = 498. Both steps check out.

Step 4: Interpret the result. At 498 days, kitchen scraps alone would take well over a year to fill 216 gallons. In real life leaves and yard trim fill it much faster, which is why a large open bin suits fall cleanup. A 37 gallons tumbler would need about 28 loads at the same rate. 37 / 1.3 = 28.4615, rounded to 28 loads. 28 x 3 = 84 days. Re-verify: 1.3 x 28 = 36.4, close to 37 gallons, and 28 x 3 = 84. That shorter cycle shows why a small tumbler needs more frequent emptying but gives you a contained batch sooner. Choose open volume if you have leaves; choose a tumbler if you want tidier batches.

5 mistakes to avoid with a compost pile

1. Buying only a kitchen caddy

A countertop pail collects scraps. It does not finish compost. Pair any 1 gallons to 1.75 Gal collector with outdoor volume or a drop-off plan. Otherwise odors build and you have nowhere to empty the pail.

2. Starving the pile of dry material

Wet food scraps mat down without leaves, straw, or shredded cardboard. You can compost at home using dry leaves and woody material from your yard alongside kitchen scraps. Stockpile a bag of dry leaves next to the pile.

3. Choking off air

A soggy, packed pile smells and stalls. Use a ventilated bin, add bulky dry material, and turn or rotate. The tumbler listing suggests a few rotations every few days. An open bin benefits from forking material from edges to center.

4. Letting scraps sit too long indoors

Empty small caddies often, rinse them, and replace filters on schedule. One stainless listing says to empty and clean weekly for best results and notes filters last 3–6 months. If fruit flies appear, empty sooner and clean the lid seal.

5. Expecting instant finished compost

Even a tumbler needs time and repeated mixing. Adding more material resets the batch. With a dual design, add fresh scraps to one side while letting the other side mature, as the listing describes. Screen unfinished chunks and return them to the pile.

FAQ

What is the simplest way to start a compost pile?

Pick a level, well-drained spot, set your outdoor bin, and alternate kitchen scraps with dry leaves. Keep the mix damp like a wrung sponge and turn it for air. Read best starting a compost bin from scratch for setup steps.

Do I need a bin, or can I pile on the ground?

An open pile works, but a bin holds shape, keeps material tidy, and improves airflow. An expandable 216 gallons bin contains leaves that would blow away. A 37 gallons tumbler adds pest seals and easier turning.

What should I put in first?

Start with coarse dry material for air, then add food scraps and leaves in layers. Avoid meat, dairy, and oils unless your manual allows them.

How often should I turn the pile?

Turn when it smells, mats down, or cools off. One tumbler listing suggests a few rotations every few days. Open piles often do well with a weekly fork turn. If the listing for your bin gives other guidance, follow the manufacturer’s manual.

Why does my pile smell?

Too much wet food and too little air or dry material cause odor. Add dry leaves, fluff the pile, and empty kitchen caddies more often. Check that lids and filters are clean and seated. Persistent odor plus pests means pause fresh additions and turn the pile.

Can I compost in winter?

Yes, but breakdown slows in cold weather. Keep the pile full, sheltered, and damp, and keep adding. One additive listing says it is effective in wide temperature ranges, but the listing does not give degrees. Check the product listing and see best starting a compost bin in winter.

What should I not compost?

Do not add pet waste, charcoal ash, treated wood, or materials with pesticide labels that forbid composting. For a longer list, see best things you can t compost. When in doubt, follow your city rules and the product manual.

Bottom line

Choose volume first. Get the 216 gallons expandable bin if you have leaves and room for a true pile. Get the 37 gallons dual-chamber tumbler if you want contained batches on a patio. Add a kitchen collector sized to your cooking — 1.3 gallons stainless, 6.62 liters stay-open, or 4.92 liters ventilated with bags — and empty it often. Use the 2.5 lb bacterial additive only after outdoor volume is set. If you cannot place an outdoor pile, do not buy one yet; collect scraps for a shared site instead.
