Material flow analysis (MFA), also referred to as substance flow analysis (SFA), is an analytical method to quantify flows and stocks of materials or substances in a well-defined system. MFA is an important tool to study the bio-physical aspects of human activity on different spatial and temporal scales.
The core of MFA is a weighted factorial analysis: MFA firstly provides the classical results of the factorial analyses. 1. Representations of individuals in which two individuals are close to each other if they exhibit similar values for many variables in the different variable groups; in practice the user particularly studies the first ...
In MFA studies for a region or on a national level the flows of materials between the natural environment and the economy are analyzed and quantified on a physical level. The focus may be on individual substances (e.g. Cadmium flows), specific materials, or bulk material flows (e.g. steel and steel scrap flows within an economy).
Statistics on EW-MFA cover all solid, gaseous, and liquid materials, except for water and air. However, water in products is included. EW-MFA includes statistics on material flows crossing the national (geographical) border, i.e. imports and exports. [1] EW-MFA strives to produce a mass balance of material flows. It systematically categorises ...
Inside an iPhone . Material criticality is the determination of which materials that flow through an industry or economy are most important to the production process. It is a sub-category within the field of material flow analysis (MFA), which is a method to quantitatively analyze the flows of materials used for industrial production in an industry or economy.
