That's a great question! Living in the city means dealing with limited space and specific waste challenges, so choosing the right liner is more important than you might think. Honestly, the "best" liner depends on your primary need.
For most everyday kitchen bins, I strongly recommend standard-sized, drawstring plastic bags. They're affordable, readily available, and the drawstring makes for a clean, secure tie-up—crucial for avoiding spills in a cramped apartment hallway. Look for a "medium duty" or "leak-resistant" label to handle typical food wrappers and damp coffee grounds.
If odor control is your top priority (think small kitchens or infrequent disposal), scented liners or bags with baking soda are a game-changer. They help neutralize smells between take-outs. For a more sustainable choice, certified compostable bags are fantastic for lining a small countertop caddy for food scraps, especially if your city offers compost collection. Just be sure to use them in a well-ventilated bin, as they can break down faster if things get too moist.
My top tip? Always measure your can! There's nothing worse than a bag that's too small and slips in, or too large and bunches up. A well-fitted liner looks neater and functions better. Ultimately, a reliable, correctly sized liner that you'll use consistently is the real winner for hassle-free urban living.
