That's a great question! Many of us are trying to reduce plastic waste, and finding a compostable liner for our outdoor bins is a common hurdle. The good news is, yes, there are compostable bag liners designed to fit standard outdoor trash bins, but it requires a bit of attention to detail.
First, check the dimensions. Standard outdoor bins often hold 13-gallon bags. Many reputable eco-brands now offer compostable bags in this exact size. Look for keywords like "Tall Kitchen" or "13-Gallon" on the packaging. It's crucial to measure your bin's height and circumference, as "standard" can vary slightly.
The material matters most. Genuine compostable bags are typically made from plant-based materials like cornstarch (PLA) or PBAT. Always look for official certifications on the bag, such as BPI (USA) or OK compost HOME/INDUSTRIAL (Europe). These ensure the bag will break down properly in a commercial or home compost system, unlike misleading "biodegradable" plastics.
Performance is key. Modern compostable liners are much stronger than early versions. They resist tears and can hold typical kitchen scraps and dry waste. For wet or heavy loads, consider double-bagging or opting for a bag specifically rated for heavier content. Remember, they are designed for organic waste—don't use them for general trash that goes to a landfill.
Finally, manage expectations. These bags are perfect for collecting food scraps and yard waste destined for your compost pile or municipal green bin. Pair them with a bin that has good airflow to minimize moisture buildup. By choosing a certified, correctly sized compostable liner, you can make your outdoor waste routine truly sustainable.
