21% of Solid Waste going to Landfills from MoCo is food scraps. This waste stream is biodegradable but even things most prone to rot need the right conditions. Food scraps in trash bags under many other trash bags in a landfill tend to 'mummify' and take decades to break down. Food scraps in a well tended compost situation can break down in weeks. Or even days in industrial compost facilites (like this state-of-the-art one in New York state. )
