Polaris Energy saving News: With the extensive use of the medical care industry and the
development of medical disposable products, medical waste generation is growing quickly.
The most recent statistics show that there were 261, in the city to the community solid waste
pollution prevention information, only those 261 cities this year, medical waste quantity attained 547,500 tons.
Another one figures show that at the end of 2012, the total number of health associations of 950 297 beds 5.7248 million, according to an average of 1 kg per bed
medical waste every day, the whole number of medical waste generated in the country annually to reach 200 million tons.
Faced with such a huge amount of waste created, but many cities are composed of one or a
few waste disposal in a single way of managing medical waste incineration. After a case of waste incineration plants closed down, the authorities and the hospital at the
management of medical waste and daily operations, will face enormous challenges.
In actuality, hospital waste generated a big part of municipal solid waste and similar low-
risk waste, about 75% to 90%, the remaining 10% to 25% are believed to be dangerous, it could pose
a health hazard, hospitals infectious waste is generally not more than 10 percent of the whole garbage. Reduce the amount of waste generated must be effective category management as the
assumption, but now garbage classification level of the hospital, worrying.
Medical waste collection is key to the implementation of environmentally sound management
of medical wastes, but most Chinese physicians don’t pay attention to the sort processing
medical waste, and open area, no obvious signs, classification level is not high.
General hospital with regular household garbage bins and yellowish medical, hospital and clinic
personnel told Post logo, the swab and other body fluids come into contact with the patient
garbage into yellow garbage bag. But the reporter visited some hospitals found that blood
tests and outpatient medical room yellow garbage bags of medical waste both areas, but
also paper, food packaging and other general household waste.
A poll conducted at a hospital in Wuhu, Anhui Province indicates that at some health care personnel classification concept is unclear, non-infectious waste, such as medical equipment packaging, special medical waste combined with yellow bag. Although such an approach did not
cause harm to the spread of disease, but it raises the cost of processing medical waste.
research on the status of management and disposal of medical waste in a primary hospital also
revealed that the passing rate of garbage deposited only 45%. The survey also pointed out
that a whole lot of medical waste in the absence of sterilization, transported to the transfer
station processing, which may cause secondary pollution garbage occur during transport.
Many local medical waste disposal fee is calculated according to bed, the total amount of waste
generated by hospitals not directly related to the processing fee paid. If the hospital
improve the control level, reducing the amount of waste created, and the identical amount of beds, garbage fees won’t be reduced, so that’s not conducive to encouraging
hospitals supply waste separation and reduction.
Medical waste are complicated, such as infectious wastes, pathological wastes, chemical
wastes and damaging waste, etc., about different textile materials, plastics, glass,
metal and human organizations, a single treatment is hard to achieve for many different medical garbage harmless treatment.
For different types of medical waste, we have a different processing method and apparatus
have been developed and utilized around the world. Autoclaving is
most likely the most widely used non-burning disinfection, along with chemical processing
technology, processing technology and microwave plasma processing technology.
China is currently widely used is incineration, this approach will generate large quantities of
harmful gas mixture, such as hydrochloric acid, dioxins and furans, as well as toxic
metals lead, cadmium and mercury. However, research indicates that some old equipment
medical incinerators, waste is a direct smoke exhaust emissions.
South China Institute of Environmental Sciences after a medical waste incineration plant in
Guangdong Province as the research object, through the collection and analysis incineration
plant and the surrounding soil and plant samples, PAHs understand incineration plant (PAHs)
distribution, sources and pollution levels. 
South China Institute of Environmental Sciences once a medical waste incineration plant in
Guangdong Province as the research object, through the collection and analysis incineration
plant and the surrounding soil and plant samples, PAHs understand incineration plant (PAHs)
distribution, sources and pollution levels. The results show that medical incinerators soil
surrounding a certain degree of contamination of PAHs detected in the soil 16 polycyclic
aromatic hydrocarbons, PAHs total amount ranging 11.83ng / g ~ 788.24ng / g, mean 236.681ng
/ g; in the study area downwind of the prevailing winds in the soil, total PAHs were
significantly higher than the prevailing winds soil content, and the total concentration of
PAHs in soil increases with distance showed a gradual decrease.
