Previous Research
Microwaves couple well with certain organic materials and past research undertaken by Dr. Emery and EWI in the 1980's and early 1990's, determined the key wastes, ie. medical waste and tires, that would provide the platform from which EWI could expand and thrive. These successes came from trials of many materials including:
- Wood drying and impregnation
- Sewage sludge and peat moss drying
- Oil recovery from tar sands and shales
- Treatment of contaminated soils
- De-sulphurization of coal
- Auto shredder residue treatment
From that testing and the market conditions at the time, it was decided that medical waste destruction and tire recycling held most promise and should move to the next phase of development. A number of these original materials are now being re-considered, as market and economic situations have changed. The company then built a number of tests units:
- Tire processing unit capable of treating 300 tires/day (TR-300)
- Medical waste destruction unit - circular configuration (M-100)
- Medical waste destruction unit - tunnel configuration (MD-1000)
Each of these was used for considerable testing, development and re-engineering with the result that the MD-1000 is now being manufactured and sold and the TR-300 has been the basis for new designs for 1500, 3000 and 6000 tire per day models.
