- 12. Arshad Surti Industrial application Pharmaceuticals The chemical company BASF now makes its annual output of the painkiller ibuprofen some 2 billion tablets in a three- step rather than a six-step process.23 Of the atoms used in the synthesis, which are mostly derived from hydrocarbons, 77% make it into the final product compared with 40% before
- 13. Arshad Surti Industrial application Pharmaceutical Another leading drug for treating high cholesterol, Zocor (simvastatin), traditionally used a multistep method involving large amounts of hazardous reagents that produced a large amount of toxic waste. A new method for synthesizing the drug uses an engineered enzyme and a low-cost feedstock to develop a greener route for synthesizing sitagliptin, the active ingredient in a treatment for type 2 diabetes. This led to an enzymatic process that reduces waste, improves yield and safety, and eliminates the need for a metal catalyst.
- 14. Arshad Surti Industrial application Pharmaceutical Another notable drug that now requires less waste to produce is the chemotherapy drug paclitaxel (marketed as Taxol). It was originally made by extracting chemicals from yew tree bark, a process that used a lot of solvent in addition to killing the tree. The drug is now made by growing tree cells in a fermentation vat.
