Nearly 100 businesses are showcasing their products at the fourth Environment and Energy Tech Hanoi 2012 (ENTECH Hanoi) that opened in Hanoi on May 23.

Displays at the 200 booths include energy-saving products and equipment using advanced and environmentally friendly technology such as solar water tanks, solar batteries, and small hydroelectric plants.

Pham Duc Tien, Deputy Director of the Hanoi Department of Industry and Trade said the exhibition offers a chance for businesses in Hanoi and the northern region to promote investment, introduce their products and raise competitiveness.

It also creates a trading venue for domestic and foreign businesses operating in the energy and environment field, while helping to raise public awareness of energy efficiency and environmental protection, contributing to renewing a growth model for green and sustainable socio-economic development, Tien said.

The four-day exhibition, the largest of its kind in Vietnam, is co-organised by Hanoi People’s Committee, the Ministry of Industry and Trade, Hanoi Energy Conservation Centre and Vietnam Association for Conservation of Nature and Environment.-VNA
