Environmental Research Brief: Pollution prevention assessment for a manufacturer of pharmaceuticals

The Waste Minimization Assessment Center at Colorado State Univ. performed an assessment at a plant that manufactures intermediates for pharmaceuticals and other chemicals. Waste streams generated in the greatest quantities are waste solvents that are reused onsite, incinerated as fuel in an onsite boiler, or shipped offsite for disposal. The greatest cost savings could be achieved by reusing additional amounts of methylene chloride in the plant. This research brief discusses the process, existing waste management practices, pollution prevention opportunities, and gives additional recommendations. Tables summarize current waste generation and recommended waste minimization opportunities
