What Should You Consider When Choosing a Backyard Compostable Bag?
When choosing the best backyard compostable bag, several factors should be taken into account to ensure effectiveness and environmental friendliness.
- Material: The type of material used in the compostable bag is crucial, as it should be made from plant-based substances such as cornstarch or sugarcane. These materials break down more effectively in a composting environment, unlike traditional plastic, which can persist for hundreds of years.
- Certification: Look for certifications from reputable organizations, such as ASTM D6400 or EN 13432, which indicate that the bags meet specific compostability standards. This ensures that the bags will decompose in a composting facility and not just in a landfill, providing peace of mind regarding their environmental impact.

- Cost: While compostable bags are generally more expensive than regular plastic bags, it’s important to find a balance between cost and quality. Investing a little more in a high-quality compostable bag can lead to better results in your composting efforts and contribute positively to the environment.
- Usage Restrictions: Some compostable bags are only suitable for specific types of waste, so it’s essential to check compatibility with your composting system.
