Actually, dirty's quite wasteful. Recovering those expensive chemicals rather than emitting them can easily pay for itself over time. Initial costs are high, but when the chemicals are expensive, recovery and recycling is well worth it. Emitting is cheap and easy, but poor engineering. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
