Market Examples - Household name brands have validated this market sector. Glad produces a specific line of "Compostable" bags (lemon-scented and neutral) designed for municipal composting programs. Similarly, Hefty offers "EcoSave" compostable trash bags. These products allow consumers to dispose of organic waste without separating the bag from the contents, streamlining the composting process for waste management facilities.

Their distinct green-colored bags are ubiquitous in city parks. Another example is Wild One, which markets cornstarch-based, extra-thick bags.
