Most household composting fails because the family doesn’t follow a consistent rule for what goes in the compost bin versus the trash. Adults learn the rules over time but kids — especially kids under 10 — need explicit guidance. A clear, visual compost chart posted near the kitchen sink is one of the more practical tools for getting consistent family-wide composting.

But not all charts work. Some charts are too detailed (kids ignore them); some are too vague (kids guess wrong); some look adult-focused (kids don’t engage). The chart that actually works is simple, illustrated, and matched to the food your family actually eats.
This article walks through the design principles for a compost chart kids will actually follow, with specific examples of what works and what doesn’t.
Why most compost charts fail with kids
Three common failure modes:
Too many categories. A chart with 20+ items in compost / 15 items in recycle / 10 items in trash overwhelms kids. They scan, get lost, and give up.
Adult vocabulary. “Foodservice paperboard” doesn’t mean anything to a 7-year-old. “Biodegradable” is abstract. The chart needs to use words kids already know.
Pictures that look like clip art rather than food. Generic illustrations don’t help kids identify their actual food. The chart needs pictures that look like what they actually see on their plate.
Located somewhere they don’t see. A chart in a basement or garage doesn’t get read. The chart needs to be where kids are when they’re making the compost-or-trash decision — the kitchen.
Negative framing. “Don’t put this in compost” turns the chart into a list of rules. Kids respond better to positive framing.
The chart structure that works
The chart that actually works for kids has these features:
Big simple categories. Compost / Recycle / Trash. Three categories, not five.
Pictures, not just words. Each item is illustrated, not just named.
Kid-relevant items. The chart features food kids actually eat (banana peels, apple cores, pizza crusts, granola bar wrappers), not abstract adult food (kale stems, fennel fronds).
Color-coded. Green for compost, blue for recycle, red for trash. Universal color associations that kids already know.
Posted at kid eye level. Not high on the wall; at the height where a 6-year-old can read it without standing on tiptoes.
Brief explanatory text. A one-sentence description per item that tells the kid why this goes in this bin. “Banana peel: the worm food at the bottom of the compost loves this!”
Updatable. Print on a magnetic backing or laminate so you can add new items as the family discovers them.
What to include in the compost section
For most family households, the compost section of the chart should cover:
Fruit waste:
– Banana peels
– Apple cores
– Orange peels (cut into smaller pieces)
– Watermelon rinds
– Berry caps and stems
– Mango pits (slow to break down but acceptable)
– Pear and peach pits
– Grape stems
Vegetable waste:
– Carrot tops and ends
– Onion skins
– Celery ends
– Bell pepper cores
– Lettuce ends and outer leaves
– Cucumber peels
– Tomato ends
– Potato peels
Bread and grain waste:
– Pizza crusts (without cheese stuck on)
– Bread heels and crusts
– Stale crackers
– Plain rice or pasta (no sauce)
– Tortilla scraps
Other plant matter:
– Coffee grounds and filter
– Tea bags (paper kind, not nylon)
– Eggshells (crushed)
– Dried herbs and spices in small amounts
– Cut flowers when they wilt
For compost liner bags used in kitchen collection bins, BPI-certified bags can also go in compost — useful to include on the chart.
What to include in the trash section
The chart should also show what doesn’t compost, so kids understand both sides:
Animal products (most home methods):
– Meat scraps
– Fish bones and skin
– Bones (chicken, beef, pork)
– Dairy products (cheese, yogurt, butter)
– Eggshells (yes — but separately handled at home compost)
Note: bones and dairy can go in some composting systems but not most home systems. The chart can simply put these in trash for simplicity.
Oily and greasy food:
– French fries and other fried foods
– Greasy take-out containers
– Salad dressing-coated greens
– Buttered or oiled vegetables
Wrappers and packaging:
– Plastic chip bags
– Plastic wrappers
– Foil wrappers (Hershey bar foil)
– Plastic-coated cardboard (microwave popcorn bags)
– Wax paper (if it has a slick plastic-feel coating)
Items that look compostable but aren’t:
– Plastic produce bags (even if labeled “compostable” — most aren’t)
– Single-use coffee cups (most have plastic coating)
– Plastic take-out containers
– Styrofoam containers
– Anything with metal or plastic that can’t be separated
What to include in the recycle section
For completeness, the chart should also cover what gets recycled:
Paper:
– Newspapers
– Magazines (not glossy inserts)
– Cardboard boxes (broken down)
– Cereal boxes
– Paper grocery bags
Containers:
– Aluminum cans (rinsed)
– Glass bottles (rinsed)
– Plastic bottles (rinsed, labeled #1 or #2)
– Steel cans (rinsed)
– Empty milk cartons (if accepted locally)
Visual design that works for kids
Color contrast. High contrast between text and background. Black or dark text on white or light background. Avoid colored text or busy backgrounds.
Large simple illustrations. Each item should be recognizable at a glance. A line drawing of a banana peel works; a photo-realistic banana peel is overkill.
One illustration per item. Don’t try to show three different types of banana peel on one row. Pick one canonical illustration.
Consistent spacing. Same spacing between items helps kids scan the chart. Random spacing makes it harder to find specific items.
Numbered or bulleted, not paragraphs. Kids scan vertically; horizontal text isn’t read. Use bullets or numbers.
Brief item names. “Banana peel” not “Used banana peeling material.” “Apple core” not “Discarded apple inner structure.”
A printable example
Here’s a simple chart layout you can adapt for your family:
📦 GOES IN GREEN COMPOST BIN:
– 🍌 Banana peel — worms love this
– 🍎 Apple core — composts in 8 weeks
– 🥕 Carrot top — same with all veggie scraps
– 🍕 Pizza crust — just the bread, no cheese stuck on
– ☕ Coffee grounds and filter — full of nitrogen
– 🥚 Eggshells (crushed) — add calcium to soil
– 🌿 Tea bags (paper) — not the nylon mesh kind
– 🌳 Dead leaves and flowers — natural compost food
🗑️ GOES IN BLACK TRASH BIN:
– 🥩 Meat and fish scraps — attracts pests
– 🧀 Dairy (cheese, yogurt) — smells bad in compost
– 🍟 Greasy food — oil breaks compost
– 📦 Plastic wrappers — never composts
– ☕ Plastic-lined coffee cup — most aren’t compostable
♻️ GOES IN BLUE RECYCLE BIN:
– 📰 Newspapers and magazines
– 📦 Cardboard boxes (flattened)
– 🥫 Aluminum cans (rinsed)
– 🍾 Glass bottles (rinsed)
– 🚰 Plastic water bottles (rinsed)
How to introduce the chart to kids
Three approaches that work:
Walk through the chart together. Sit down with the chart and review each item with your kids. Explain why each item goes where. Answer questions. This conversation matters more than the chart itself.
Make it a game. When you’re cooking, point to scraps and ask “compost or trash?” Praise correct answers; gently correct wrong ones. After a week or two, kids internalize the patterns.
Involve kids in compost bin emptying. When the bin gets full, let a kid carry it to the outdoor compost pile (with supervision). Seeing the pile and connecting the kitchen scraps to the outdoor cycle reinforces why composting matters.
Connect to garden. If you garden, harvest something from your compost-fed garden bed and connect it back: “this carrot grew in soil from our compost.” Closes the loop visibly.
Common questions kids ask
Three questions that come up:
“What about the chicken bones from dinner?”
Most home compost systems can’t handle bones. Bones go in trash. (Note: bones are technically compostable in commercial facilities but not in home piles. For simplicity, the chart says trash.)
“What about the napkin I used?”
Used paper napkins are compostable. Throw them in compost. (Soiled napkins are even better — they have organic matter on them.)
“What if the package says ‘biodegradable’ or ‘eco-friendly’?”
Many products labeled biodegradable or eco-friendly are not actually compostable. Look for the BPI certified seal specifically. If you’re not sure, ask an adult or default to trash.
“What happens if I put the wrong thing in?”
Nothing bad happens immediately. Wrong items in compost slow it down or contaminate it slightly. Wrong items in trash are wasted but not harmful. Just try to do better next time.
What if your family has different food than the example chart
Adapt the chart to your family’s actual food. If your family eats:
- Lots of takeout: Add “take-out containers” with notes about which kinds compost (paper containers without plastic lining) vs which go to trash (plastic-coated containers, plastic cups).
- Lots of pet food: Pet food cans in recycling; pet food itself in trash; pet waste in trash (not compost).
- Cultural foods not on the standard list: Add them. The chart works best when it features food your kids actually see.
For compostable food containers and similar items, including the most common ones your household uses helps kids learn the distinction.
Frequency of chart updates
The chart isn’t static. Update it:
- Every 6 months as kids age (more detail for older kids, simpler for younger)
- When you discover new items that come up in your household waste
- When kids ask questions that aren’t on the chart
- Annually to refresh memory and make it feel like a current resource
What this teaches kids
Beyond composting per se, the chart teaches kids:
Sorting and categorization. Foundational thinking skill — putting things in categories based on attributes.
Cause and effect. Compostable things become soil; non-compostable things stay in landfills. Real consequences for real choices.
Pattern recognition. Identifying which items are compostable based on what they look like and what they contain.
Family routines. Composting becomes “what our family does” rather than “something special.”
Environmental thinking. Connecting daily small choices to bigger environmental impacts.
The chart is a tool for teaching, not just sorting. The bigger lesson is the habit of thoughtful waste handling.
The bigger picture
Family composting works when everyone participates. Kids who learn composting habits early carry them into adulthood. A simple compost chart, posted prominently, customized to your family’s actual food, and reviewed periodically with kids, is one of the higher-leverage tools for building family composting habits.
The chart isn’t perfect; some sorting will still be wrong. But it shifts the family from “guess and hope” to “check the chart” — and the chart gives a consistent reference that builds confidence over time.
For households new to composting with kids in the family, the compost chart is one of the first investments worth making. A few hours to design and post a chart pays off in years of more consistent family composting.
For B2B sourcing, see our compostable supplies catalog or compostable bags catalog.
For procurement teams verifying compostable claims, the controlling references are BPI certification (North America), EN 13432 (EU), and the FTC Green Guides on environmental marketing claims — these are the only sources U.S. enforcement actions cite.
