Frequently Asked Questions

1What is OptiMaser™ ?

It is a Microwave Medical Waste Disinfection System (MMDS)

2What is MMDS ?

•MMDS stand for: Microwave Medicalwaste Disinfection system

• It is an alternative non- burn green point of generation treatment technology for the disinfection of biomedical waste.

• Microwave disinfection is essentially a revolutionary method where disinfection occurs through the action of moist heat and steam generated by microwave energy through internal molecular heating thereby providing extraordinarily high level of disinfection.

3What is the minimum temperature and time required for disinfection through microwave ?

Temp: 90-100 °C Time : 47 minutes cycle

4What is the level of disinfection?

105 - 107 log , highest known to man

5Has it been tested for its microbiological efficacy?

Yes, has been tested for its microbiological efficacy by:

Haffkine Institute, Mumbai. All bacterial cultures , including the bacterial spores of deadly pathogens , as well as the fungal cultures which have the potential to cause “Hospital Acquired Infection” were found to be killed after 30 minutes of exposure in the system at 90°C

Sanjay Gandhi Post Graduate Institute of Medical Sciences Lucknow, Department of Microbiology The report state that OptiMaser Microwave Medical Waste Disinfection System (MMDS) has good microbial efficacy. In one cycle run of 45 minutes 105 organisms of ATCC Escherichia coli 25922 were killed yielding zero colony count.

Rukmani Devi Beni Prasad Jaipuriya Hospital Jaipur, Department of Microbiology Report of Biowaste sterilizer states that all samples were sterile after 48 hour of aerobic culture.

6Why such technology is required for Medical Waste Disinfection?

According to a WHO report, about 1.3 million children die in India each year from syringe reuse and that some 22 million people are infected. In India about five billion injections are given annually whereas only 1.5 billion syringes are manufacturedi (Upto 64% of illegal reuse of used syringes).

Sub-urban & Rural Health

• In rural health care centers and sub urban centers the problem is even bigger where due to lack of unviable option of waste collection and disposal and due to lack of awareness on alternate treatment technologies, health care centers are either disposing their waste with regular solid waste, or burning it in make shift incinerators

• Increase in use of plastic disposables and growing use of plastic syringes (in the immunization program) has increase the amount of plastic waste. Waste burn in incinerators is giving rise to additional problem of rise in highly toxic gaseous emissions like Dioxins and Furans which can cause cancer and respiratory diseases.

• It is a point of generation treatment technology therefore eradicates the rising graph of ‘Hospital acquired infection’.

• Pre dispatch disinfection of bio medical waste eliminates the chances of pilferage.

• Disinfected waste is easy to be disposed off as non hazardous municipal solid waste thus making the management of biomedical waste easy and economical

• It has zero effect on environment as it requires no secondary devices, has no emissions and no chemicals involved.

• Zero cross contamination

7Does OptiMaser™ treat all categories of medical waste? If not, how will I manage to dispose of the other categories?

• OptiMaser™ Treats almost all categories of biomedical waste which can be misused or have the potential of illegal resale / reuse.

• Such waste has enormous potential to spread Hospital Acquired Infections. It can treat 4 critical categories of waste as mentioned under the Bio-medical Waste (Management & Handling) Rules, 1998. This includes:

CAT-3: Microbiology & Biotechnology Waste? Wastes from laboratory cultures, stocks or specimens of microorganism live or attenuated vaccines, human and animal cell culture used in research and infectious agents from research and industrial laboratories, wastes from production of biological toxins, dishes and devices used for transfer of cultures.

CAT-4: Waste Sharps??
Needles, syringes, scalpels, blades, glass, etc. that may cause puncture and cuts. This includes both used and unused sharps.

CAT-6: BIO-MEDICAL Waste??
Items contaminated with blood, and body, fluids including cotton, dressings, soiled plaster casts, lines beddings, other material contaminated with blood.

CAT-7: BIO-MEDICAL Waste??
Wastes generated from disposable items other than the waste sharps such as tubings, catheters, intravenous sets etc.

It does not treat Human/animal body parts for which deep burial and incineration are the two options recommended Liquid waste and chemical waste can be disposed after proper treatment by methods as recommended in the Bio-medical Waste (Management & Handling) Rules, 1998.

8What kind of pathogen / bacteria cannot be treated by the OptiMaser™?

OptiMaser™ kills almost all pathogens /bacteria known to man.
