DA NANG, Vietnam -- Vietnamese import-export firm, NewTech, and Singapore's Wah Lee Tech have signed a Letter of Intent (LoI) on the construction of a medical waste treatment plant in Vietnam, Vietnam News Agency (VNA) reported.

A source from NewTech told that the LoI, which was signed in Singapore on Sunday, details building a hazardous medical waste treatment plant with capacity of 20 tonnes per day.

It said the two sides agreed to establish a joint-venture company, of which the Vietnamese side took a 51 per cent share, to develop a plant in Ho Chi Minh City, Hanoi or Da Nang, and a high-tech service related to waste treatment.

The plant will use latest technology in medical waste treatment without burning, dumping or pollution measures.

According to the LoI, the two sides will survey the three biggest cities in Vietnam to build the plant on an area of 8,000sq.m.
