How to Start a Home Composting System That Actually Works

Learn how to start and maintain a practical home composting system, balance greens and browns, prevent odors and pests, troubleshoot slow piles, and know when compost is ready to use.

Quick answer: A reliable home composting system needs four things more than it needs expensive equipment: carbon-rich “browns,” nitrogen-rich “greens,” enough moisture, and enough oxygen. Choose a convenient location, keep a reserve of dry brown material beside the bin, bury fresh food scraps in the center, cover every food addition with browns, and adjust the pile based on what you observe. A healthy pile should smell earthy rather than sour or rotten, feel about as damp as a wrung-out sponge, and gradually lose volume as microorganisms break the materials down.

Composting at home is often presented as a simple instruction: put food scraps and leaves in a pile and wait. That description is technically true, but it skips the decisions that determine whether the result is pleasant and useful or wet, smelly, pest-prone, and discouraging. The practical skill is not “making things rot.” It is managing decomposition so that oxygen-loving microorganisms can do most of the work under conditions you can easily maintain.

This guide is designed for a beginner who wants a system that fits normal life. You do not need to memorize an exact chemistry formula, buy a powered machine, or turn the pile every day. You do need to understand what each ingredient contributes, how to recognize imbalance, and how to correct the pile without throwing everything away. The process below works for typical backyard bins and open piles, and it also explains when a tumbler, worm bin, municipal collection service, or another method may be a better fit.

1. Decide what kind of composting system actually fits your home

Start with your living situation, not with a product. A homeowner with a yard, a renter with a balcony, and an apartment resident with no outdoor space have different constraints. The “best” system is the one you can feed consistently, maintain without inconvenience, and keep acceptable to neighbors, family members, landlords, or local rules.

Backyard bin or enclosed pile

For many homes, an enclosed backyard bin is the easiest starting point. It accepts kitchen plant scraps plus dry yard material, limits the visual mess, and can be positioned near a garden or storage area. A basic bin does not need a motor or complicated mechanism. Ventilation matters more than appearance. The U.S. Environmental Protection Agency describes backyard composting as a practical home option and emphasizes the same biological requirements regardless of container style: carbon-rich materials, nitrogen-rich materials, moisture, and oxygen.

An enclosed bin is especially useful when you want to discourage pets or wildlife. Look for a lid that closes securely and ventilation openings that are small enough not to create obvious access points. If rodents are common in your area, consider a bin that can be reinforced at the base with suitable hardware cloth. EPA guidance notes that food scraps should be covered and buried and that openings should be tightly controlled when pest prevention is important.

Open pile

An open pile is inexpensive and easy to turn with a fork. It works well when you have a steady supply of leaves, grass, garden trimmings, and space away from living areas. The tradeoff is exposure. Rain can make the pile too wet, dry weather can pull moisture out of it, and visible food scraps can attract animals. If you choose an open pile, plan to manage the top layer deliberately instead of treating the heap as a dump site.

Tumbler

A tumbler is useful when you value neatness, easy turning, or separation from the ground. It can reduce the effort required to mix materials, but it does not remove the need for balance. A tumbler filled mostly with wet kitchen scraps can still become dense and unpleasant. It may also run out of space quickly if your household produces more scraps than the drum can process before the batch matures.

One practical approach is to use a tumbler as an active first stage, then move partly decomposed material to a curing bin. That prevents you from endlessly mixing new scraps into material that is trying to finish.

Vermicomposting

Worm composting can work well indoors, in a garage, or in a protected small-space setting. It is not simply a tiny version of a hot outdoor compost pile. A worm bin is a living habitat, so feeding rate, bedding, temperature, moisture, and food choices matter. EPA guidance says worms can process many fruit and vegetable scraps, coffee grounds and filters, and similar materials, while some foods should be avoided or limited. If your goal is primarily to handle small amounts of kitchen scraps without a yard, vermicomposting may be more suitable than forcing an outdoor-style pile into an indoor container.

Municipal or community collection

If you have no appropriate space, a local food-scrap collection service can be the most practical answer. This is not a failure to compost “properly.” It is still resource recovery. EPA specifically lists municipal and community composting as alternatives for households that cannot compost at home. Commercial facilities may also accept materials that a backyard pile should not, but you must follow the accepted-material list for your own program rather than assuming every item labeled compostable can go in the bin.

Success check: You have chosen a system when you can answer four questions: Where will it live? What materials will go into it? Where will you store dry browns? What will you do with finished compost? If one of those answers is missing, fix the workflow before buying equipment.

2. Choose a location that makes maintenance easy

Location affects whether you will keep composting after the initial enthusiasm fades. A perfect ecological spot that is annoying to reach in rain or winter is less useful than a reasonable spot you can visit in thirty seconds.

For an outdoor bin, choose ground that drains rather than staying waterlogged. Avoid placing a pile where runoff will flow toward a doorway, walkway, or neighboring property. A location with some shade can reduce moisture loss in hot weather, while a site with at least some airflow helps prevent a stagnant, saturated environment. USDA’s People’s Garden guidance recommends a dry location in sun or partial shade for a typical backyard setup.

Keep a water source within reach, but do not assume you will need to water constantly. The material itself may supply plenty of moisture, especially if you add fruit and vegetable scraps or fresh grass. The point of nearby water is to make correction easy when the pile becomes dry.

Also plan access for finished compost. If the bin is against a fence with no working space, harvesting from the bottom can become awkward. Leave enough room to use a garden fork, shovel, bucket, or wheelbarrow. If you expect large seasonal volumes, consider two compartments: one active and one curing. That simple separation solves the common problem of adding fresh scraps forever and never allowing any batch to finish.

For households concerned about rodents, do not place the bin immediately beside an open door, pet feeding station, or area where spilled bird seed already attracts animals. Compost management is easier when you are not adding another food cue to an existing pest hotspot.

Common mistake: Hiding the bin in the farthest corner because compost feels unattractive. The longer and less convenient the trip, the more likely kitchen scraps are to stay indoors until they smell, or to be dumped carelessly without a brown cover. Convenient systems are maintained systems.

3. Learn the practical difference between “browns” and “greens”

The most useful beginner model divides compost ingredients into browns and greens. Browns are generally carbon-rich and structurally dry. Greens are generally richer in nitrogen and often contain more moisture. Microorganisms use carbon as an energy source and nitrogen to build proteins and grow. They also need water and oxygen.

You do not need to calculate the laboratory carbon-to-nitrogen ratio of every banana peel. In fact, extension recommendations vary in how they express ideal proportions because material density and composition vary. EPA home-composting guidance gives a practical household target of roughly two to three parts browns to one part greens by volume, while scientific discussions may describe an approximate carbon-to-nitrogen ratio near 30:1 by weight. Those are not contradictory instructions. One is an easy mixing rule; the other is a chemical relationship.

Useful brown materials

Dry fallen leaves
Shredded plain cardboard without plastic coating
Torn uncoated paper in moderate amounts
Small dry twigs and chipped woody material
Straw
Untreated sawdust used cautiously because it is very carbon-rich and can compact
Dry plant stems that are not diseased or contaminated with persistent herbicides

Dry leaves are particularly valuable because they are easy to store, easy to sprinkle over wet food, and provide structure that keeps air spaces in the pile. If your neighborhood produces leaves seasonally, save them in bags or a simple leaf cage. A reserve of browns is the composting equivalent of keeping basic ingredients in a pantry.

Useful green materials

Fruit and vegetable scraps
Coffee grounds and paper coffee filters
Fresh grass clippings in thin amounts
Fresh green garden trimmings
Plant-based kitchen scraps
Crushed eggshells, although shells decompose slowly and are not a major nitrogen source

Fresh grass deserves special attention. A thick mat of wet clippings can collapse into a dense, airless layer and smell strongly. Mix it with dry leaves or another coarse brown material instead of dumping a lawn mower bag as one compressed slab.

Materials a typical backyard beginner should leave out

For a conventional home pile, avoid meat, fish, bones, dairy products, greasy foods, and large quantities of oil. These materials can attract animals and create odor problems in a pile that does not achieve the controlled temperatures and management of a commercial facility. EPA home guidance also recommends excluding pet waste from conventional food-and-yard compost intended for garden use.

Avoid treated or painted wood, glossy plastic-coated paper, produce stickers, conventional plastic, glass, metal, and other contaminants. “Biodegradable” and “compostable” labels also require attention: some certified products are designed for industrial conditions and may not break down well in a backyard pile. Follow your local collection rules if the material is going to a municipal facility.

Do not add plants that have been recently treated with a herbicide unless the product label and local guidance clearly indicate the residues are compatible with composting. Persistent herbicides can survive long enough to damage sensitive garden plants. If you are uncertain about the origin of hay, manure, or grass clippings, caution is more useful than optimism.

Build a simple kitchen-to-bin workflow

Keep a small lidded container for plant scraps in the kitchen. It does not need special ventilation if you empty it regularly. When it is full, carry it to the compost bin, make a shallow opening in the active center, empty the scraps, mix them lightly with existing material, and cover the fresh food with a generous layer of dry browns.

That last step prevents many beginner problems at once. Covering food reduces exposed odor, discourages flies, hides scraps from animals, absorbs excess moisture, and adds carbon. EPA recommends covering food scraps with about four to eight inches of browns in a backyard system.

Success check: If your household generates a bucket of wet kitchen scraps every few days, you should be able to point to a separate stock of dry material that can cover those scraps every time. If you routinely run out of browns, solve that storage problem before adding more greens.

4. Build the pile so air and moisture can reach the microbes

Compost does not need decorative layers, but structure matters. Begin with a loose base of coarse brown material so the bottom is not a compacted mat. Small twigs, dry stems, or chunky leaves can create air spaces. Then add mixed browns and greens rather than one huge block of each.

If you are starting with very dry material, moisten it as you build. Water should be distributed through the pile rather than poured only on the surface. The familiar “wrung-out sponge” comparison is useful: damp throughout, but not dripping when squeezed. Both EPA and university extension guidance use this description because it is more practical than asking homeowners to measure precise moisture percentages.

Particle size changes the speed of decomposition. Smaller pieces expose more surface area to microorganisms. Chopping a pumpkin rind into chunks or shredding cardboard usually speeds the process. But pulverizing everything into a dense paste can reduce airflow. Aim for a varied texture: pieces small enough to break down, with enough coarser material to keep pore spaces open.

Do not compress the pile to “fit more.” A compost bin is not a trash compactor. Oxygen is a required ingredient in aerobic composting. EPA defines composting as managed aerobic biological decomposition; when oxygen becomes limited, different processes dominate and odors are more likely.

Do you need a compost starter?

Usually, no. Plant material, soil particles, existing compost, and the environment already contain abundant microorganisms. A scoop of finished compost can be useful as an inoculating material, but buying a special starter is not normally necessary to make a pile work. If a pile is inactive, first investigate moisture, nitrogen, oxygen, pile size, and temperature before assuming it lacks a commercial additive.

Do you need a thermometer?

A compost thermometer is optional. It can be useful if you enjoy monitoring the process or are intentionally managing a hot pile. A well-maintained active pile may rise significantly in temperature; EPA notes that backyard piles can reach roughly 130–160°F under good conditions. However, UConn Extension also points out that many home piles never become very hot and can still produce good compost, only more slowly.

This distinction matters because beginners sometimes treat “not hot” as “failed.” A small pile, cool season, slow feeding pattern, or high-carbon mix can compost without dramatic heat. Temperature is a clue, not the only definition of success.

5. Maintain the pile with observation instead of a rigid schedule

Some guides tell you to turn compost on a fixed schedule. That can work, but observation is more transferable. Turn when the pile becomes compacted, develops an odor associated with poor aeration, or when you want to speed decomposition by moving outer material toward the active center. If you are comfortable with slower composting, you can turn less often.

When turning, the goal is not to stir endlessly. Lift and loosen material. Move the cooler outside layer toward the center and redistribute wet and dry pockets. If you discover a soggy zone, mix in dry browns. If you discover a dry dusty center, add water gradually while mixing.

Use your senses as diagnostic tools

Smell: Healthy compost should generally smell earthy, leafy, or mildly organic. A rotten-egg or rancid smell usually points to excess moisture and low oxygen. An ammonia-like smell often suggests too much nitrogen-rich material relative to carbon. Rutgers and Cornell troubleshooting guides both connect these odors with predictable corrections: more aeration and more dry carbon material.

Feel: Grab a handful from inside the pile using gloves. It should feel moist but not release a stream of water when squeezed. If water runs out, the pile is too wet. If the material feels crispy and dusty, decomposition will slow.

Appearance: Fresh recognizable ingredients are normal near the top. Older material should darken, soften, and lose its original shape. White fungal growth can be a normal decomposer community, especially in woody or dry material. A few insects and other small organisms are also part of outdoor decomposition; the goal is not sterility.

Temperature: Warming indicates active microbial decomposition. A temperature rise after turning or adding greens tells you the pile is biologically active. A cold pile may simply be mature, small, dry, nitrogen-poor, or affected by weather.

Maintain a two-container habit indoors

One of the easiest ways to prevent a wet pile is to think of composting as two waste streams: a small kitchen container for greens and a dry reserve for browns. Many people only collect food scraps because they are generated every day. Then they discover that the outdoor pile contains mostly water-rich material. The brown reserve fixes that imbalance at the source.

Pause feeding when you want a batch to finish

If you keep adding fresh scraps forever, the pile will contain material at many stages of decomposition. That is not wrong, but it makes harvesting difficult. When the bin is nearly full, stop adding to that batch and start a second bin or use another collection method while the first batch finishes. Turn it, adjust moisture, and let the microorganisms complete the work.

6. Troubleshoot the seven problems that make beginners quit

Problem 1: The pile smells rotten

A rotten or sour smell usually means the pile has too little oxygen, too much water, too many greens, or a combination of those conditions. Start by turning the pile to loosen compacted material. Add dry leaves, shredded cardboard, straw, or another appropriate brown. If rain has saturated an open pile, cover it temporarily while preserving airflow.

Do not try to fix a wet pile by adding more food because the food seems “dry enough.” Most fruit and vegetable waste contributes additional moisture. Use genuinely dry structural carbon.

Verify the fix: After mixing, the pile should feel springier and no longer release excess liquid. The odor may not disappear immediately, but it should become less intense as oxygen returns.

Problem 2: The pile smells like ammonia

An ammonia odor often means nitrogen is abundant relative to available carbon. Mix in browns thoroughly instead of placing a decorative handful on top. Dry leaves or straw are particularly helpful because they both add carbon and improve structure.

Problem 3: Nothing seems to be happening

Check moisture first. A dry pile can sit almost unchanged because microbial activity requires water. Moisten while turning so water reaches the center. If the pile is already damp and smells fine, it may need more nitrogen. Add a modest amount of greens and mix them in.

Size can also matter. A tiny pile loses heat quickly. Rutgers and Cornell troubleshooting resources both list inadequate pile size as a reason a pile may not heat. But remember that heat is not mandatory for slow composting. If the material is gradually darkening and shrinking, the system may simply be operating slowly.

Problem 4: Fruit flies appear every time you open the bin

Exposed kitchen scraps are usually the cause. Bury fresh scraps in the center and cover them with dry browns or finished compost. Rinse the indoor collection container often. Avoid leaving sweet fruit waste on the surface. If flies are already abundant, temporarily reduce food additions while increasing dry cover and allowing the active material to catch up.

Problem 5: Rodents or larger animals investigate the pile

First remove attractants that do not belong in a conventional backyard pile, especially meat, dairy, grease, and exposed cooked food. Cover plant scraps completely. Use a secure lid and inspect gaps around the base. EPA recommends controlling openings and, where appropriate, reinforcing a bin so pests cannot easily enter.

Do not respond by using poison inside or beside the compost pile where pets, wildlife, or garden organisms may be exposed. Solve access and food-attractant problems structurally.

Problem 6: The pile is slimy and compacted

This often happens with large amounts of grass clippings or soft food waste. Break apart the mass and add coarse browns. The objective is physical structure as much as chemistry. A correct theoretical carbon ratio is not enough if the pile is compressed into an airless block.

Problem 7: The pile is full but never becomes usable compost

You may be mixing fresh inputs with finished material indefinitely. Stop adding to the batch. Turn it well, correct moisture, and allow it to mature. EPA recommends a curing period after active decomposition; its current home guidance says to allow at least four weeks of curing after the pile stops reheating and visible food scraps have largely disappeared.

7. Know when compost is finished instead of judging by the calendar

Composting time varies widely with method, climate, ingredient size, pile volume, moisture, and turning. EPA says a well-maintained home pile can be ready in roughly three to five months, while a neglected pile may take a year or longer. Penn State Extension gives a similar typical range around three to four months for an actively managed pile. Treat those numbers as planning estimates, not deadlines.

Finished compost has several indicators:

It is dark brown to nearly black rather than brightly colored with fresh scraps.
It has a loose, crumbly texture.
It smells earthy rather than sour, rotten, or strongly ammoniacal.
Most original ingredients are no longer recognizable.
The pile does not substantially reheat after turning.
The volume has decreased significantly.

Some slow materials can remain visible even when most of the batch is finished. Eggshell fragments, small woody pieces, fruit pits, and tough stems may persist. Screen them out and return them to the next active batch instead of waiting for every fragment to vanish.

Why curing matters

Material that looks brown is not automatically mature. During curing, slower biological processes continue and the compost stabilizes. Immature compost can compete for nitrogen or contain organic acids and other compounds that are less desirable around sensitive seedlings. Give the batch time after active heating slows, especially if you plan to use it in planting mixes or around young plants.

If you are unsure, use finished compost first as a surface amendment around established plants rather than replacing potting mix with a large proportion of questionable material. Compost is a soil amendment, not automatically a complete standalone growing medium.

8. Use finished compost where it solves a real soil problem

Compost improves soil by adding stable organic matter and supporting physical structure, water management, and nutrient cycling. It should not be treated as a magic fertilizer that automatically corrects every deficiency. If you are growing vegetables, fruit, or other nutrient-demanding plants, soil testing can still be useful because repeated applications of compost and fertilizers can raise some nutrients beyond what plants need.

EPA suggests incorporating roughly two to four inches of compost into the upper six to nine inches of soil when using it as an amendment, or applying it as a surface mulch. Those are general examples, not a command to add the maximum amount every season. Adjust to your soil, plants, and existing organic matter.

Garden beds

Spread mature compost over the surface and mix it lightly into the upper soil where appropriate. In established no-dig beds, you can often apply compost as a top layer and allow weather, roots, and soil organisms to integrate it gradually.

Around established plants

Use compost as a surface layer while keeping it away from direct contact with woody trunks and plant crowns. A layer that is too deep and piled against stems can hold excessive moisture where you do not want it.

Lawns

Screened mature compost can be applied as a thin topdressing. The key word is thin: grass blades should remain exposed rather than buried under a thick blanket.

Containers

Use compost as one component of an appropriate container mix rather than assuming pure compost will provide ideal drainage, aeration, and structure. Container plants have different physical requirements from plants growing in open ground.

Before adding more fertilizer

Do not assume that “organic” inputs cannot create excess nutrients. Compost composition varies with feedstock, and repeated applications can raise phosphorus or other nutrients. If a productive garden has received compost for years, periodic soil testing can prevent unnecessary additions and help you target what is actually missing.

9. Adapt the system to seasons, vacations, and real household life

A sustainable compost habit must survive weeks when you are busy. The system should therefore fail gracefully. If you cannot turn for two weeks, the pile should not become a crisis. If you travel, the kitchen container should be empty and fresh scraps covered before you leave. If winter slows decomposition, the bin should still safely hold appropriate materials until biological activity increases again.

Hot weather

Check moisture more often because open piles can dry from the outside inward. Shade or a breathable cover can reduce moisture loss. Do not respond to heat by flooding the pile; water gradually while turning.

Rainy periods

Protect an exposed pile from becoming saturated. Add extra browns if food scraps and rainfall are both increasing moisture. Ensure water can drain from the base rather than pooling underneath.

Winter

Cold weather slows decomposition, particularly in small piles. UConn Extension notes that composting can continue at a reduced pace through winter and become more active again when temperatures rise. Keep covering new scraps with browns and avoid interpreting seasonal slowdown as failure.

Vacation

A compost pile does not need feeding on a schedule. Before leaving, bury any recent kitchen scraps, add a brown cover, and make sure the pile is not waterlogged. You do not need a neighbor to add food simply to “keep it alive.”

10. Decide whether to upgrade, expand, or change methods

After a few months, evaluate the system based on bottlenecks rather than marketing. If the active bin fills before compost matures, the solution may be a second curing bin. If turning is physically difficult, a tumbler or aeration tool may help. If you have no browns in summer, improve seasonal storage. If rodents remain a problem despite correct feeding, upgrade the enclosure.

For apartment dwellers, a worm bin or local collection service may be more practical than trying to maintain an aerobic pile in a sealed indoor bucket. For households producing unusually large volumes of food scraps, community or municipal processing can complement a backyard system instead of forcing the home pile to accept more than it can handle.

Be cautious with countertop “composters” that grind and dehydrate food. EPA currently distinguishes this output from finished compost: pre-processing appliances can reduce volume and weight, but the dried material still requires further biological processing before it becomes stable compost. Such appliances may still be useful for odor control or storage, but buy one for what it actually does, not because the word composter appears in marketing.

A complete beginner workflow you can copy this weekend

Choose the method. For a yard, start with a ventilated lidded bin or simple enclosed pile. For no outdoor space, investigate vermicomposting or local collection.
Choose the site. Use a convenient, drained location with room to turn and harvest material.
Stockpile browns. Collect at least one large bag or container of dry leaves, shredded plain cardboard, or similar carbon material before you begin regular kitchen-scrap additions.
Start with loose structure. Place coarse brown material at the bottom and add a mixed layer of greens and browns.
Manage moisture. Aim for the feel of a wrung-out sponge. Add water only when material is genuinely dry.
Bury food scraps. Put plant-based kitchen waste in the active interior rather than leaving it exposed.
Cover every food addition. Add several inches of browns on top.
Observe weekly. Check smell, moisture, compaction, and visible progress. Turn when you need more oxygen or faster mixing.
Correct instead of restarting. Smell usually means add air and browns; dryness means water; inactivity may mean moisture, nitrogen, size, or weather.
Stop feeding a full batch. Give it time to finish and cure rather than adding scraps forever.
Harvest when mature. Look for dark color, crumbly texture, earthy smell, little reheating, and few recognizable scraps.
Use compost thoughtfully. Apply it as an amendment or mulch and continue soil testing when garden fertility decisions matter.

Frequently asked questions

Does compost need to be in direct sun?

No. Sun is not the engine of composting; microbial activity is. A dry site in sun or partial shade can work. In hot climates, some shade may make moisture easier to maintain. Prioritize drainage, convenience, airflow, and access over trying to maximize sunlight.

How often should I turn compost?

There is no single required schedule. Frequent turning can speed decomposition by restoring oxygen and mixing outer material into the center. Less frequent turning produces slower compost. Turn when the pile is compacted, too wet, smelly, or when you want to accelerate an active batch.

Can I compost citrus?

Small amounts of citrus peel are generally acceptable in a conventional outdoor compost pile when mixed with other materials. Worm bins are different; EPA vermicomposting guidance recommends avoiding citrus and some strongly odorous foods. Match the ingredient to the system.

Are eggshells useful?

Yes, but they break down slowly. Crushing them increases surface area. Do not expect shells alone to rapidly correct soil calcium problems or pH. Use soil testing when a nutrient or pH decision matters.

Can compost catch fire?

Large commercial or agricultural compost piles can generate substantial heat and require professional fire-management practices. A normal, well-managed household pile is much smaller, but you should still avoid adding hot ash, charcoal, cigarettes, or ignition sources. If a pile produces smoke rather than harmless steam, treat it as a fire emergency and follow local emergency guidance.

Is mold in compost bad?

Not usually. Fungi are part of decomposition, especially in carbon-rich woody material. Mold alone is not a reason to discard a pile. If you have respiratory sensitivity, avoid inhaling dust or spores when turning dry compost; moisten dusty material and use appropriate personal protection.

Can I use unfinished compost around plants?

It is better to let the material mature. Active compost can continue decomposing, temporarily tie up nitrogen, generate heat, or contain compounds that are not ideal for roots and seedlings. If you must manage partly finished material, use it cautiously as a surface layer away from sensitive stems rather than mixing a large amount into a seed-starting medium.

Why does my compost shrink so much?

Shrinkage is normal. Water is lost, carbon is metabolized and released as carbon dioxide, and bulky plant tissues collapse as they decompose. EPA notes that a cured batch may shrink to roughly one-third of its original volume.

Final takeaway

Successful home composting is less about following a perfect recipe and more about building a system that is easy to correct. Keep dry browns available, cover food scraps, maintain moisture without saturation, preserve airflow, and let the pile finish before demanding finished compost from it. Those habits prevent most odor, pest, and slowdown problems.

Your first action does not need to be buying a bin. Collect a week of plant-based kitchen scraps and estimate how much dry brown material you can reliably obtain. If you can supply both streams and choose a convenient location, you already understand the most important part of the system. The mistake to avoid is treating the compost bin like a garbage can. Every addition should support the biological process that turns waste into stable, useful soil amendment.
