Microwave Remediation (Disposal) of Hazardous (e.g. Medical) Wastes

Highly Innovative, Green Technology For Localized, Point-of-Service Medical Waste Remediation

Microwave-Remediation-01A highly innovative, very inexpensive, patented, green remediation technique that allows for rapid processing of medical waste at the point of generation (eliminating centralized collection) in Remediator instruments the size of a water cooler or large photocopier. Based on a patented, environmentally benign, high-boiling liquid that is five times as microwave-active as water. Remediation costs are 1⁄3 those for environmentally-unfriendly incineration (which is currently still the most widely used remediation technique).

Highly Innovative, Green Technology for Localized, Point-of-Service Medical Waste Remediation
  • Rapid, portable, point-of-service destruction of wastes at point of generation.
  • Extremely environmentally benign.
  • Patented technology uses liquid, b.p. ca. 300°C, that is five times as microwave-active as water and is environmentally benign, coupled with benign microwave enhancers.
  • Not microwave-steam. Ambient pressure.
  • Handles mixed wastes, including sharps, disposable scalpels.
  • Larger, 20 L Remediator model is the size of a large photocopier. Smaller, 5 L model is the size of a small water cooler.
  • Low power.
  • Remediated waste can be disposed of as regular trash (“Class 10 Municipal Waste” in the U.S.).
  • Superior in terms of cost, bulk, ease of use and, above all, environmental benignness, as compared to extant technologies such as incineration, microwave-steam, sterilizing liquids and autoclaving.
  • Technology is currently available for licensing in the US and European Union.

SYNOPSIS
  • Rapid, portable, point-of-service destruction of wastes at point of generation.
  • Patented technology uses liquid, b.p. ca. 300°C, that is five times as microwave-active as water and is environmentally benign, coupled with benign microwave enhancers.
  • Not microwave-steam. Ambient pressure.
  • Handles mixed wastes, including sharps, disposable scalpels.
  • Low power. 2 electrical connections for each unit:
    • US: 1 X 110 VAC, 1 X 220 VAC, single phase.
    • European Union: 2 X 220 VAC, single phase.
  • Remediated waste, of size < 6 mm, can then be disposed of as regular trash ("Class 10 Municipal Waste" in the U.S.).
  • Superior in terms of cost, bulk, ease of use and, above all, environmental benignness, as compared to extant technologies such as incineration, microwave-steam, sterilizing liquids and autoclaving.
  • Two models currently available as prototypes, 5 L and 20 L. The larger, 20 L model, is the size of a large photocopier.
  • Technology is currently available for licensing in the US and European Union.

DESCRIPTION AND OPERATION
  • Extremely environmentally benign: Major component of microwave-active liquid is a food additive. No emissions of any nature due to very high b.p. of microwave active fluid.
  • Demonstrated to be effective against the hardiest spores. Effective against viruses and prions. Technology originally developed for the Marine Corps for disposal of biological warfare (BW) agents.
  • Portable, point-of-service model eliminates overhead and training associated with centralized waste collection and disposal.
  • Dimensions:
    • Prototype Model uWS-5L (5 L model): 122 cm (48″) H X 92 cm (36″) W X 51 cm (20″) D.
    • Prototype Model uWS-20L (20 L model): 122 cm (48″) H X 102 cm (40″) W X 92 cm (36″) D.
    • The larger, 20 L model, is the size of a large photocopier.
  • Handles waste with substantial liquid content.
  • Rapid operating time: Each remediation run typically takes less than 3 hours to complete.
  • Microwave active fluid is reusable up to 15 times before recycling is required.
  • Suggested service-contract business model, where service company picks up recycled microwave active fluid and services equipment if needed.

COST
  • Low cost: Estimated at ca. US$1000/tonne (in year 2014). Compare with incineration (currently ca. US$3000/tonne), microwave-steam (currently ca. US$3700 to US$5000/tonne), sterilizing liquids (currently ca. US$4000/tonne), on-site autoclaving (currently ca. $5000/tonne).
  • Most cost-effective model is “service model”, with leased equipment and full service over multi-year period.
