At the hospital, every day there are many medical waste. Among them, the garbage such as empty glass vial, vials, infusion bottles ... is particularly difficult to handle, many places, not just pile up there know how to handle.

Private Hospital Thoi Lai District, Hanoi. Tho monthly about 120 liters of glass waste is discharged. Previously, this trash do not have a handle, just bring up the environment causing environmental pollution and endanger human health.

Homemade glass disposal

Dr. Hiep Nguyen Hieu, director Thoi Lai District Hospital, has sought to handle garbage "stubborn" is. Doctors Association has built an incinerator at the back of the hospital. However, when burning, smoke and gases generated environmental pollution affects the health and lives of people around.

In addition, the costs, especially fuel, for each high incineration should also make it difficult to handle. Waste glass must be fired at temperatures from 8000 to the new 10.000oC burn but then clots and still not break down when put into the environment.

Doctors Association for a glass tube into the grinding mill fry test. These tubes are broken into small pieces. Dr. Hiep think of taking advantage of these fragments to cast into cloth lined street - just helpful just do not pollute the environment.

But to handle a large amount of garbage needs to be larger and specialized machines, so the doctor Agreement waste barns to seek to acquire the appropriate metal bar, brought manufacturing into a crusher. After the machine finished, he brought a large amount of ground testing of hospital waste glass.

Over 2 times rolled, the only glass beads as small as grains of sand size, size 1 / 4 mm3. He first glass sand mixed with cement and lime and then poured into molds. After drying, this mixture made up of solid sheets of material with high hardness. He brought the sheet material to the road pads, lining the floor of the hospital warehouse and saw fit.

Low Cost

From the initial success, the doctor strongly Agreement practical applications in waste treatment at the hospital. Since late in 2008, he has directed the hospital every day to make the classification of waste from the outset, to separate glass bottles with other waste.

In addition to the largest benefits in terms of environment, this method also saves the cost of waste disposal for many hospitals.

Incinerator with a glass from the U.S., about 500 million purchase price, can process 1,000 liters of glass within 10 hours, consumes about 30 kWh of electricity and 220 liters of diesel oil, have to spend for costs of This waste is 3.33 million.

For the method of physician Association, a self-made machine cost a total of 4 million (not included), the simple structure, compact. Also the amount of garbage as above, just about 12 kWh of electricity, not diesel, the cost of more than 12,000 contracts. This method superiority over Vietnam in that incinerators utilize waste glass to create the cloth and apply in life.

The doctor Nguyen Hieu Association continues to develop research into scientific topics titled "Machine processing of medical waste (glass group)".
