Biodegradable bags are designed to break down naturally in the environment, reducing pollution and waste. Made from materials like corn starch or plant-based polymers, these bags decompose through the action of microorganisms, turning into natural substances like water, carbon dioxide, and biomass. Unlike traditional plastic bags, which can take hundreds of years to decompose, biodegradable bags typically break down within a few months to a few years, depending on environmental conditions. They are often used for shopping, food storage, and waste collection, making them a more eco-friendly alternative to conventional plastic options.
