The formula to calculate the E Factor is:
\[ E = \frac{M_w}{M_p} \]
Where:
The E Factor, or Environmental Factor, is a metric used in green chemistry to quantify the environmental impact of chemical manufacturing processes. It is defined as the mass of waste generated per mass of product produced. A lower E Factor indicates a more environmentally friendly process with less waste. It is an important tool for assessing the sustainability of chemical processes and for driving improvements in process design.
Let's consider an example:
Using the formula to calculate the E Factor:
\[ E = \frac{50}{200} = 0.25 \]
This means that the E Factor for this scenario is 0.25.
