E-Factor Environmental Impact Factor

In the late 1980s Roger Sheldon introduced E-factor to evaluate the environmental impact of manufacturing processes. History The Royal Society [CC BY-SA 3.0 ( /by-sa/3.0) or CC BY-SA 4.0 ( /by-sa/4.0)], via Wikimedia Commons

Product PROCESS MATERIALS A basic process…

Waste (kg) E factor = Product (kg) E-factor measures the amount of waste produced in a certain process. E-factor is calculated by dividing the mass of waste (kg) by the mass of product (kg)

Principle 1. Prevention. Design chemical syntheses to prevent waste, leaving no waste to treat or clean up. 2. Atom Economy. Design syntheses so that the final product contains the maximum proportion of the starting materials. There should be few, if any, wasted atoms. 3. Less Hazardous Chemical Synthesis. Design syntheses to use and generate substances with little or no toxicity to humans and the environment. 4. Designing Safer Chemicals. Design chemical products to be fully effective, yet have little or no toxicity. 5. Safer Solvents & Auxiliaries. Avoid using solvents, separation agents, or other auxiliary chemicals. If these chemicals are necessary, use innocuous chemicals. 6. Design for Energy Efficiency. Run chemical reactions at ambient temperature and pressure whenever possible.

Principle 7. Use of Renewable Feedstocks. Use raw materials and feedstocks that are renewable. Renewable feedstocks = farm products or the wastes of other processes; depleting feedstocks = fossil fuels (petroleum, natural gas, or coal) or are mined. 8. Reduce Derivatives. Avoid using blocking or protecting groups or any temporary modifications if possible. Derivatives use additional reagents and generate waste. 9. Catalysis. Minimize waste by using catalytic reactions. Catalysts are used in small amounts and can carry out a single reaction many times. They are preferable to stoichiometric reagents, which are used in excess and work only once. 10. Design for Degradation. Design chemical products to break down to innocuous substances after use so that they do not accumulate in the environment. 11. Real-time Analysis for Pollution Prevention. Include in-process real-time monitoring and control during syntheses to minimize or eliminate the formation of byproducts. 12. Inherently Safer Chemistry for Accident Prevention. Design chemicals and their forms (solid, liquid, or gas) to minimize the potential for chemical accidents including explosions, fires, and releases to the environment.
