Solvent Recovery


Introduction

The recycling and recovery of solvents is an important consideration in active pharmaceutical ingredient (API) manufacture.  60–70 % of the wastestream from such manufacturing can be solvent so its recovery can have a positive effect on the carbon footprint of a given process. This granule describes what solvent recovery is, how it works, and the considerations that need to be taken as part of its implementation.

Learning Objectives

By the end of this topic, you should:

  • Understand how solvent recovery can be environmentally beneficial.
  • Have a high-level understanding of the considerations required when investigating the feasibility of solvent recovery.
  • Have an awareness of the technologies that can be used to conduct solvent recovery.
  • Understand the challenges that industry faces in implementing solvent recovery.
