Yes. Unlike plastic trash bags and some of the "biodegradable" trash bags, compostable trash bags are intentionally developed from plant-based materials to be compostable. While it's true that biodegradable materials do naturally degrade, they sometimes leave non-organic residues (such as microplastic or toxic metals). Meanwhile, a compostable trash bag will break down into water, carbon, and humus. Humus is an organic fertilizer full of nutrients and great for plants and soil.
