Tiivistelmä	Emergy Analysis, developed by systems ecologist Howard T. Odum and formally presented in his 1996 book, is a biophysical accounting method that converts all inputs to a system — energy, materials, labor, and services — into a common unit of solar energy equivalents called solar emjoules (sej). By tracing how much prior environmental work was required to produce each input, it enables researchers, engineers, and policymakers to compare fundamentally different resource types on a single thermodynamic basis.	Material Flow Analysis (MFA) is a systematic method for quantifying the flows and stocks of materials within a defined system boundary over a specified time period. Introduced comprehensively by Paul H. Brunner and Helmut Rechberger in their 2004 handbook, MFA applies mass-balance principles to track how raw materials, products, wastes, and emissions move through industrial, urban, or national metabolisms, enabling evidence-based resource management and waste policy.
