How to Evaluate E Factor?

E Factor evaluator uses E Factor = Total Mass of Waste/Mass of Product to evaluate the E Factor, The E Factor formula is defined as the ratio of the mass of waste per mass of product. It highlights the waste produced in the process as opposed to the reaction, thus helping those who try to fulfil one of the twelve principles of green chemistry to avoid waste production. E Factor is denoted by EF symbol.

How to evaluate E Factor using this online evaluator? To use this online evaluator for E Factor, enter Total Mass of Waste (MW) & Mass of Product (MPr) and hit the calculate button.
