Waste from pharmaceutical plant
A small pharmaceutical plant manufactures erythromycin base and
erythromycin derivatives (erythromycin thiocyanate, erythromycin
stearate, erythromycin estolate). These products are used as growth promoters
and as a disease preventative in animal feed. The products are manufactured as
bulk chemicals for further processing. To identify alternative strategies based
upon prevention and waste minimization, an assessment by a team of company
personnel was applied. At the time of the assessment the plant was operating at
50% of its design capacity. The manufacturing technology is based on batch
fermentation.
