Hundreds of tons of waste are incinerated neatly by this machine without releasing any smoke at all. It can also filter the oppressive air in crowded markets and “eradicate” thick black smoke billowing from the chimneys of industrial factories…

Mr. Loan (right) introducing the machine |
This is a dust and gas treatment technology – a unique invention with high application value by a young physician from Ha Tay province.
To witness it firsthand, we visited the Hoa Binh Provincial General Hospital, where the machine is being tested. Mr. Truong Quy Duong – the hospital director firmly stated: “Yes, the machine we are using, although it was initially produced manually, has fantastic features“.
Mr. Duong led us to the back of the hospital, where the machine is located for observation. The machine is a continuous, closed-loop system that includes an inlet for waste, an exhaust pipe, and filters to process the smoke generated during combustion. Although the operating principle of the machine is not complicated, it is extremely scientific. The incineration system (heated to nearly 2,000°C), smoke propulsion system, and high-speed rotary filtering system will swirl all the smoke into lime water (or diluted sodium hydroxide) and then settle, allowing clean air to rise.
At first, Mr. Duong was skeptical, so he placed a white towel over the chimney to “test” it. The machine ran continuously for several hours, incinerating tons of waste while the towel remained pristine, with no stains caused by emitted smoke.
Pointing to a pile of waste near the wall, about the size of a small table, he excitedly shared with us: “That’s three tons of medical waste! The hospital collects it every two days for incineration. Previously, it polluted the entire area, but now the issue has been completely resolved. Applying this technology in factories and industrial zones will be very beneficial“. Next to where we stood, above the machine’s chimney, branches of fig trees with vibrant green leaves were still bearing young fruit…
The inventor of this machine is the young physician Nguyen Dinh Loan, who currently lives in Phu Son commune (Ba Vi, Ha Tay). Mr. Loan explained that the idea came to him over ten years ago while pursuing his family’s traditional medicine career, and he felt the need to establish a pharmaceutical workshop.
Mr. Loan continued by noting that having a pharmaceutical workshop would require a significant amount of coal and firewood for drying herbs; and with that comes smoke, dust, and unpleasant odors that would affect the health of the villagers.
Nguyen Dinh Loan often wandered alone, sometimes standing silently for hours to observe the billowing smoke from textile factories and chemical plants… then returning home to jot down notes and calculations. Whenever he had spare time from his duties as a physician, Nguyen Dinh Loan would eagerly read chemistry textbooks and gather materials on research projects and environmental journals.
He stated that his project is entirely based on observations from nature. As a practitioner of medicine, the young physician always thinks of his homeland and the healthcare sector first.
Mr. Loan mentioned that he has completed several projects and is eager to share them with relevant authorities and scientists to implement them in real life. These include studies on cleaning the To Lich River and lakes in Hanoi using cost-effective methods; solutions for flood control and management in case of dike breaches; methods for purifying air and fire prevention in crowded, suffocating markets…
