Enter the mass of waste and the mass of product into the calculator to determine the E Factor. The E Factor is a measure of the environmental impact of a chemical process.
E Factor Formula
The following formula is used to calculate the E Factor:
E = frac{M_w}{M_p}Variables:
- E is the E Factor (kg of waste/kg of product)
- Mw is the mass of waste (kg)
- Mp is the mass of product (kg)
To calculate the E Factor, divide the mass of waste by the mass of product. This will give you the E Factor in kg of waste per kg of product, which is a dimensionless number indicating the efficiency of a chemical process in terms of waste production.
What is an E Factor?
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.
How to Calculate E Factor?
The following steps outline how to calculate the E Factor:
- First, determine the mass of waste (Mw) generated by the process in kilograms.
- Next, determine the mass of product (Mp) produced by the process in kilograms.
- Use the formula E = Mw / Mp to calculate the E Factor.
- Finally, compare the E Factor with industry standards or previous processes to assess environmental impact.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Mass of waste (Mw) = 200 kg
Mass of product (Mp) = 50 kg
