Weekly Review: Compost Is Not a Vibe Check

Item of the Week

Compostable bags.

A compostable bag is not a permission slip. It only belongs in curbside compost if your local program accepts that exact kind of bag.

That sounds picky, but it is the difference between helping the compost system and sending a plastic looking contaminant into a facility that may not be able to process it. Some programs accept certified compostable liners. Some want food scraps loose in the cart. Some allow paper bags but not compostable plastic bags.

Safe default: if your city or hauler does not clearly say compostable bags are accepted, put the bag in the trash and empty accepted food scraps into the green bin.

Do wooden skewers and toothpicks go in compost?

Bare wood and bamboo usually get the green light. The trouble starts with plastic flags, foil toppers, paint, lacquer, beads, glue, glitter, or anything that turns a simple stick into a tiny mixed material problem.

Also, do not toss long sharp skewers into a bin like you are launching spears into the underworld. Break them into smaller pieces when you can, especially for curbside compost carts.

Recycling Fact

Compost rules are not just about whether something can break down eventually.

They are about what a specific collection program and processing facility can handle. A backyard pile, a city food scraps cart, and a yard waste only bin are three different systems. Onion skins may be fine in compost. Coffee filters may be fine. Houseplant leaves may be fine. But the bin label still wins.

That is the part people get wrong: they judge by the item, not by the program.

Before tossing something questionable, check the local rule. Check the right bin before you throw it away: What Bin Is This

What's New

This week leaned hard into compost decisions, especially the annoying borderline items that look natural but still need a second look.

• Do wooden skewers and toothpicks go in compost? Plain wood is usually compostable, but coatings and decorations are the catch.
• Can dryer lint go in compost? Most dryer lint belongs in the trash, especially when it may contain synthetic fibers or dryer sheet residue.
• Do houseplant leaves go in compost? Dead leaves and trimmings are usually fine, but pest covered or diseased plant material is a bad donation to your compost.
• Do onion skins go in compost? Onion and garlic skins can usually go in compost, with the usual local program caveat.
• Do compostable bags go in curbside compost? The label is not enough. Your local program has to accept them.
• Do coffee filters go in compost? Plain paper filters are usually fine. Pods, synthetic mesh, and lined filters are a different story.

Question of the Week

Can dryer lint go in compost if most of my clothes are cotton?

Usually, no for curbside compost.

Even if your laundry is mostly cotton, dryer lint can still include polyester, nylon, elastic fibers, pet hair, detergent residue, dryer sheet coating, fragrance products, and pocket debris. Curbside compost programs generally do not want that gamble unless they specifically say dryer lint is accepted.

For a backyard compost pile, a tiny amount from mostly natural fiber laundry may be okay if you do not use dryer sheets or heavy fragrance products. But if you are unsure, trash is the cleaner call.
