Neutralization of medical wastes

Decontamination of medical waste has been and still one of the most important problems of health care management. Millions of tons of medical wastes are generated annually in the Russian Federation. In 2010 it was 1 748 747 tons, and in 2011 - more than 1 789 162 tons. Every year, the amount of waste increases due to increased use of disposable medical products. At the same time, class B and C wastes accounts for about 47% of the total volume.

According to the latest researches in the field of medical waste management, the polymer fraction segment is an increasing component of medical wastes.

A simple way to improve cleanliness

At the moment, there is a sufficient selection of different technologies for decontamination of medical wastes with both advantages and disadvantages. There are centralized and decentralized waste neutralization methods.

Centralized methods include incineration (burning) and pyrolysis. As a rule, such facilities serve several health facilities located in the same region. It should be noted that these technologies, especially incineration, cause great harm to the environment and human health, due to the fact that during the burning of waste, a large number of mercury compounds and dioxins are released. These compounds possess a pronounced carcinogenic, teratogenic and immunosuppressive effect.

In addition, construction and maintenance of such incinerators is very expensive.

In terms of decentralized methods of medical waste disposal, there are currently more than forty of such technologies produced by more than seven dozen manufacturers in the United States, Europe, the Middle East, and Australia.

More details about methods of medical waste neutralization

Currently, there are many different technologies that provide both centralized and decentralized methods of medical waste decontamination.

These systems have different power, automation degree and volume reduction, but they all use one or more of the following methods:

  • heating of wastes to minimum 90 - 950C by means of microwave ovens, radio waves, hot oil, hot water, steam, air or superheated gases;
  • Treatment of wastes by chemical compounds such as sodium hypochlorite or chlorine dioxide;
  • Treatment of wastes with hot chemicals;
  • Treatment of medical wastes by radiation source.

However, the latest WHO recommendations are based on no use of technologies related to chemical disinfection, and technologies for thermal disinfection are considered to be the best technologies for waste neutralization. Advantages of machine methods of disinfection are stated in SanPiN 2.1.7.2790-10:

  • ensuring a change in appearance of wastes;
  • elimination of opportunity of their repeated use;
  • an opportunity of accumulation, temporary storage, transportation and disposal of Class B and C wastes together with class A wastes.

Let's consider the most common methods of medical waste neutralization in the territory of the Russian Federation, their pros and cons.

CHEMICAL DISINFECTION BY IMMERSION.
  • Does not require waste subgrading
  • The most common method for the staff of the health facility, due to its widespread prevalence in previous years.
  • Do not reduce the number of infectious agents to a sufficient extent, due to heterogeneous permeability of the layers.
  • It contaminates the environment, unsafe for the staff.
  • Does not change the appearance of waste, does not reduce their volume.
  • Requires a large number of manipulations, including making of disinfectant solution, which is accompanied by unpleasant odor.
  • It can only be used as a temporary measure.
  • It is inadmissible for class B wastes (since they must be completely neutralized at the place of origin).
  • Expensive method, due to the high consumption of disinfectants.
  • Not recommended by WHO.

Productivity 1-5 kg/hour.

CHEMICAL DISINFECTION WITH REDUCTION IN SIZE OF WASTE PRODUCTS
  • It results in complete destruction of the infectious agents.
  • The appearance of the waste is changed, the volume is decreased.
  • Relatively small size.
  • Low initial cost.
  • Work is possible only using an expensive patented disinfectant.
  • Waste subgrading is necessary.
  • Increased humidity and weight of the wastes at the output.
  • There are no WHO recommendations

Productivity 8-12 kg/hour

MICROWAVE PROCESSING
  • Completely eliminates infectious agents from the medical wastes.
  • It is relatively cheap.
  • There is no need to connect to the water supply.
  • Small footprint.
  • High fire hazard and high EMF levels
  • There is a need for additional equipment for the purpose of destruction
  • It is necessary to use a special sensitizing reagent.
  • Waste subgrading is necessary
  • Unpleasant smell
  • Low productivity
  • There are no WHO recommendations

Productivity 1- 12 kg/hours

AUTOCLAVING
  • Completely eliminates infectious agents from the medical wastes.
  • It is safe for an environment and for human.
  • Recommended by WHO
  • The method is effective only in case of reduction in size of waste products in decontamination chamber (main active agent - water vapor - does not have any access to the packaged wastes).
  • We need to purchase additional equipment to change the appearance of the wastes.
  • Working with pressure vessels. Staff training is necessary
  • Unpleasant smell during operation
  • High initial cost of equipment and operating costs
  • It should be connected to centralized water supply and sewage system

Productivity 8-12 kg/hour

DRY HEAT TREATMENT
  • Completely eliminates infectious agents from the medical wastes.
  • It changes the appearance of medical wastes.
  • It is safe for an environment and for human.
  • WHO recommendations.
  • There is no need to sort the wastes.
  • There is no need to connect to the central water supply and sewage system.
  • An unpleasant odor can take place if the model is not equipped with filters.
  • Difficulties with disinfection of liquid wastes, additional sorbents are necessary.
  • The wastes can bake on the walls of reusable containers or capsules, due to which the declared productivity is repeatedly reduced.

Productivity 1-45 kg/hour

HYBRID STEAM AND HIGH TEMPERATURE TECHNOLOGIES
  • It results in complete destruction of the infectious agents.
  • The appearance of the waste is changed, the volume is decreased
  • There are no harmful emissions, there are filters.
  • Recommended by WHO.
  • High initial cost of equipment and operating costs.
  • Large overall dimensions of the equipment.
  • Waste subgrading is necessary.
  • Toxicity of chemical reagents used during the destruction cycle.

Productivity 15-35 kg/hour.
