That's a great question! Using a liner in an outdoor trash can isn't always mandatory, but it's a game-changer for keeping your bin clean and making waste removal a breeze. Personally, I always use one. Here’s my practical take on the options.
For most households, heavy-duty, large plastic trash bags are the go-to. Look for bags labeled for outdoor or contractor use—they're thicker and more puncture-resistant than standard kitchen bags. A perfect fit is key; a bag that's too small will slip inside, while one too large is wasteful. Sizing up (like using a 55-gallon bag for a 50-gallon can) often helps get better coverage.
For eco-conscious choices, biodegradable or compostable plastic bags are an option, but check their certifications. They're designed to break down in commercial composting facilities, not necessarily in your backyard. For yard waste, skipping a liner or using a paper yard waste bag is often the most sustainable route.
My top tips? Double-bagging for extra messy waste (like greasy BBQ leftovers), sprinking a bit of baking soda at the bottom of the bag to control odors, and securely tying the bag closed to deter pests. The right liner protects your can from stains and simplifies the messy job of taking out the trash.
