19 Business opportunity in steel sector The system to supply hot ingost from steelmaking process to roller process

20 Business opportunity in pulp and paper sector High efficiency boiler High efficiency pulp processing Automatic control the flow of pulp and steam

21 Business opportunity in food and garment sector Fluorescent lamps Energy saving Ventilation Fans Energy saving Inverter Energy saving Energy saving up to Source: Meet-Bis Boiler System

22 Business opportunity in food and garment sector (cont.) electronic sewing machine Energy saving up to Heat pump Fuel saving Solar Water Heater Energy saving up to fuel saving to Source: Meet-Bis Sew saver

23 Business opportunity in food and garment sector (cont.) Sewsaver Energy saving up to IQF Energy saving up to IQF ( individually quick frozen ) Freezer Refrigerator with screw compressor

24 Business opportunity in energy efficiency Energy managerment system and ISO Waste water treatment

25  Introduce the hi-tech to Vietnam enterprise  Implement pilot projects  Build a financial mechanism for change new technology: ESCO, leasing financial, ….  Cooperate with a Vietnam’s agency for taking the technology transfer to reduce the investment cost How to develop EE products in Vietnam

26 Case study in energy efficiency – Hoa phat group -Hoa Phat Group produce coke with capacity is 700,000 ton/year. -In Phase 1: Hoa phat already recovered waste heat for electric gerneration with capacity is 15 MW -in Phase 2: Hoa phat would like to recover the waste heat from coke making with flow is 166,000 Nm3/h and temperature is o C. Electric capacity of phase 2 is 22 MW
