Compostable cups are designed to break down naturally in composting environments, unlike traditional plastic cups. Made from materials such as PLA (polylactic acid) or paper, these cups decompose into organic matter, enriching the soil and reducing landfill waste. They are often used for beverages and food items in cafes and events. These cups are typically labeled with a compostable certification, indicating they meet specific standards for biodegradability. To ensure proper decomposition, they should be disposed of in industrial composting facilities, as home composting may not provide the necessary conditions for complete breakdown.
