Hi All, They have been using these compost biofilters for quite some time in the U.S. They tend to have big footprints but really low operating expenses. They«re used at wastewater treatment plants, MSW compost facilities, and fish processing plants to name a few. I«m happy to be of whatever help I can to my large northern neighbor.

A lot of castor oil is produces here and other place , but the e first time we hear the odour problems which can be esily solved You can solve the problem using different hot and cold extraction process which are under development very seriously in Brasil As we are in Brasil we can surley join with Irwin in the biofilter design as we do have posgraduate programme In Chemical engineering dept UFRN, Natal to do the same. The price of the castor oil sold for the petro chemical companies are very high compared to heating. It is better you find a alternate energy such as used vegetabale oil and make Biofuel for Motor . As we are in Brazil we can jointly work to solve our problem . sd Pannirselvam P.V On Apr 1, 2005 5:04 PM, Tom Irwin <[EMAIL PROTECTED]> wrote: > Hi All, > > I'm an American living in Uruguay and I may have a potential solution for > your odor problem.
