As many as 150 domestic and foreign businesses took part in an international fair to introduce their energy conservation, environmental protection and sustainable development solutions.

The three-day International Exhibition Fair for Environment and Energy Technology (Entech Hanoi -2015), which opened on May 20 in Hanoi, features 200 booths.

More than 60 businesses from the Republic of Korea — which recently signed a free trade agreement (FTA) with Vietnam — brought a wide range of new-cutting edge products to the event.

Most of the exhibits are related to engineering; renewable and alternative energy; traffic and transportation; petrol, gas and coal; and industrial waste treatment technology.

Speaking at the opening ceremony, Director of the Department of Industry and Trade Le Hong Thang said that the annual fair, launched in 2009, has over the years drawn more than 800 domestic and foreign exhibitors.

On the occasion, several Vietnamese firms were honored for their outstanding green solutions in energy saving and environmental protection.

Last year, the event led to 640 transactions and 160 signed technology transfer contracts worth 9.5 million USD.-VNA
