Micro Bio-Medical Waste Systems Inc. Enhanced Processing Technology.

LAS VEGAS--(BUSINESS WIRE)--May 3, 2004

Micro Bio-Medical Waste Systems Inc. (OTCBB: MBWS) announced today that the company has enhanced its existing environmentally friendly medical waste processing technology. The enhanced second-generation system, MBWS-TD04, incorporates the already proven, affordable and cost-effective microwave waste reduction technology with an equally affordable and cost-effective, fully closed and filtered waste ionization or NWI unit. The addition of the NWI technology now provides the company the ability and market advantage of cost effectively breaking down medical waste streams while eliminating the need for land-filling residual waste, while creating salable recyclable by-products.

The MBWS-TD04 is a medical waste stream remediation process that results in total destruction of toxic medical wastes, the creation of salable recyclable by-products and has zero adverse impact on the environment including zero emissions and zero land fill requirements. The two-phased process is comprised of components that are commercially proven and scalable. The initial disinfection and reduction phase of the process is fully automated thereby eliminating the need for the operator to manually handle infectious waste components. An automated hoist dumps material from a hospital or clinic container into the in-feed hopper at the top of the unit. Before opening, air from this hopper is treated with high-temperature steam, then extracted through high-efficiency HEPA and carbon filters which prevent any potentially harmful airborne emissions from escaping. With computers controlling the entire phase I process, an automatic signal alerts the operator when to feed more waste into the system. The material then moves into a shredder, where even vials syringes, hypodermic needles and plastic tubing are thoroughly shredded into small pieces. Shredding ensures that all processed waste receives a uniform application of disinfecting heat. The shredded material is automatically conveyed into the treatment chamber, where each piece is thoroughly moistened with high-temperature steam. The mixture is then carried by a screw conveyer beneath a series of conventional microwave generators which uniformly disinfect the waste. Computers maintain proper time and temperature to complete the process. Built-in strip charts record the variables necessary to substantiate disinfection, while continuous digital monitoring ensures that requirements for thorough treatment are exceeded by a wide margin. A lockable access port provides for easy introduction of any state-mandated testing samples. Phase I disinfects and reduces the waste stream by 80% of original volume, and prepares the reduced waste for total destruction in Phase II of the process.

The Phase II equipment consists of an air-tight water-cooled steel jacket, capable of withstanding the required vacuum for enclosed environmental processing. The reduced waste stream is mixed with a combination of silica and lime then deposited in the melting crucible by way of conveyer. This mixture is then melted in the graphite crucible housed in a water-cooled induction coil and the furnace is lined with suitable refractories.

The molten material is then poured/cast either under vacuum or inert gas environments. Once cooled, the two materials (silica carbide and stainless steel) are separated and readied for shipping to end users of these usable and recyclable materials.

Other features found in the system include:

-- Tilt and pour mechanisms

-- Casting chambers

-- Sampling ports

-- Mould handling facilities for automated and semi-automated

processing.

Medical waste streams have a high affinity for gases, in particular nitrogen and oxygen and are ideal for melting/refining in under vacuum induction to prevent contamination/reaction and emission of these gases. Melt chemistry can be controlled and manipulated by removing impurities. These can be removed using processes such as chemical reaction, dissociation, volitization or floatation.

Micro Bio-Medical Waste Systems now stands ready to solve problems in this area with ZERO ENVIRONMENTAL IMPACT(TM) and to manage communities' medical waste efficiently and effectively with environmentally friendly designed waste treatment sites in this $8 billion global industry.
