materials mass balance

If this is not known, it can be determined through the materials accounting or materials mass balance step described below.

In a materials mass balance, greater efforts are made to balance the statement:

New sources may be identified and quantified through the materials accounting or materials mass balance approach (see below).

It then quantifies these flows, and uses materials accounting or a materials mass balance to check that all losses have been identified.

This can be done by doing a materials accounting for each specific unit process, or by doing a materials mass balance.

Quantify this profile, using materials accounting or materials mass balance to verify that all losses have been identified.

Materials accounting and materials mass balances can be presented in a tabular or diagrammatic format.

Materials Accounting and Materials Mass Balance The materials accounting and materials mass balancing steps are important for any pollution prevention program: they make it possible to identify and quantify previously unknown losses.

Example of Techniques for Conducting a Baseline Review The following example illustrates some of the tools that can be used to complete a baseline review, including material flow diagrams, input/output inventories and materials mass balances.

POLLUTION PREVENTION PLANNING HANDBOOK Example Materials Mass Balance Materials mass balances are useful to organize data, identify gaps and quantify previously unknown losses.
