Material Flow Analysis (MFA) is a method used to track how materials and resources move through a system, like a factory, city, or business. Think of it as creating a detailed map that shows where materials come from, how they're used, and where they end up. This helps companies reduce waste, save money, and be more environmentally friendly. It's similar to tracking money going in and out of a bank account, but instead tracking physical materials. Some people also call this "substance flow analysis" or "resource flow mapping."
