Minimizing waste streams in production is multiply beneficial: Reduced waste disposal cost Reduced purchasing cost (wasted material had to be purchased) Reduced cost for handling, administration, storage Reduced burden for the environment Minimizing waste streams requires insight into the material balances of production processes at an appropriate level of accuracy.

Ciba® Environmental Services has developed strong tools and methods that help to get the necessary insight with reasonable effort:

Mass and Energy Flow Analysis (MEFA) - an overall tool to calculate and visualize mass, energy and even cost streams in production.
