The pharmaceutical industry has largely overlooked the benefits of recovering and recycling solvents on-site, preferring instead to rely on the purchase of virgin solvents or recovery of used solvents off-site, to replenish process-necessary solvents.
Currently, many manufacturers rely on toll processors to perform recovery of solvents. In addition to the transportation hazards, because the toll processor may deal with a number of different materials for different customers, the residue that remains in the equipment could cause cross-contamination.
Other solutions for disposal such as incineration may be less attractive from an environmental standpoint.
There is also an economic downside. Resorting to disposal of used solvents and repurchase of virgin solvents is an expensive process, and many pharmaceutical companies are leaving significant amounts of money on the table.
