The first prize, worth VND100 million (US$4,700), went to Nguyen Long Uy Bao from Ho Chi Minh City. His creation of a special bed enables sheets to be changed while patients remain in the bed.
The second runner-up was the Hanoi-based Blue and Green Environment Company with a wastewater treatment system, while a sewage classification and automation equipment brought the third prize to the Centre for Environment Technology Research and Development.
The remaining entrees were awarded with consolation prizes.
