Material Flow Analysis: Difference between revisions

Material flow analysis (MFA) is a methodology to analyze the flow of "materials" in-and-out of a system.

Built upon the law of conservation of energy, where energy can never be created or destroyed, only transferred, you can use material-balance equations to model complex systems such as the Seed Eco-Home.

Can the formal concept of "Material flow analysis (MFA)" prove useful in the design of close-looped sustainable systems?

Taken from Chapter 2.1 of Practical handbook of material flow analysis:

Substance - any (chemical) element or compound composed of uniform units (e.g. Carbon (C), Nitrogen (N), Carbon Dioxide (CO₂), and Ammonium (NH₃)).
