Description:
The U.S. Environmental Protection Agency (EPA) has funded a pilot project to assist small and medium-size manufacturers who want to minimize their generation of waste but who lack the expertise to do so. aste Minimization Assessment Centers (WMACs) were established at selected universities and procedures were adapted from the EPA Waste Minimization Opportunity Assessment Manual (EPA/625/7-88/003, July 1988). hat document has been superseded by the Facility Pollution Prevention Guide (EPA/600/R-92/088, May 1992). he WMAC team at the University of Louisville performed an assessment at a plant that manufactures bourbon whiskey and distiller dried grains as a byproduct from corn, rye, and malt. he grains are milled, mixed together, and cooked. hen the resulting mixture is allowed to ferment. fter fermentation, the mixture is processed in a distillation column. he distillate is diluted to proper proof and placed in charred barrels for aging. fter an appropriate storage period, the barrels are emptied and the contents are shipped in tank trailers. he team's report, detailing findings and recommendations, indicated that large quantities of CO2 and ethanol are vented from the plant and that significant cost savings could be achieved through CO2 and ethanol recovery.
