Waste Treatment System

This article discusses about latest developments in handling medical wastes. The article highlight features of Ecolotec, which is a large autoclave equipped with a system of blades to churn and chop the waste. The waste treatment system is in its final stages of testing and could be on the market soon. Currently, Ecolotec is studying blades of SAE 4140 chromium-molybdenum steel. The blades are sharpened daily with a belt sander, and the company may package one with the system when it reaches the market. Computer control is provided by an Allen-Bradley programmable logic controller (PLC) with a waterproof keyboard. The PLC has a wireless Internet card so, if a customer chooses, Ecolotec will be able to diagnose equipment from its headquarters. Ecolotec's executives say that, at an operating cost of 11 cents a pound, their machine costs considerably less than a waste disposal service.
