However, when companies apply green chemistry principles to the design of the API process, dramatic reductions in waste are often achieved, sometimes as much as ten-fold. This is an important roundtable focus because of the historically large amount of waste coproduced during drug manufacturing-more than 100 kilos per kilo of API in many cases. More recently, the ACS Green Chemistry Institute Pharmaceutical Roundtable ( ACS GCIPR) has favored process mass intensity, which expresses a ratio of the weights of all materials (water, organic solvents, raw materials, reagents, process aids) used to the weight of the active drug ingredient (API) produced. My view is the first principle, often referred to as the prevention principle, is the most important and the other principles are the “how to’s” to achieve itĪn often-used measure of waste is the E-factor, described by Roger Sheldon, which relates the weight of waste coproduced to the weight of the desired product. In their publication “ Green Chemistry, Theory and Practice” in 1998, Anastas and Warner introduced their 12 principles. Cue, Jr., Ph.D., BWC Pharma Consulting, LLC. Happy learning.It is better to prevent waste than to treat or clean up waste after it has been created.Ĭontributed by Berkeley W. Once again, thanks for your interest in our online courses and certification. Only the e-certificate will be made available. It will be e-verifiable at nptel.ac.in/noc.
