Specialty chemical process development can encompass a wide range of chemistries,even for the same target molecule or application.As a result,the process development organization is often working with numerous raw materials,a wide range of solvents,and mixtures of molecules and/or isomers.Processes that make low-purity chemicals with many byproducts using a wide range Of solvents can generate up to ten pounds of waste per pound of product.Although total volumes remain relatively small,in recent years,the U.S.Environmental Protection Agency (EPA) has been paying closer attention to this waste-to-product ratio.
