15 What Waste can be converted to Energy Municipal waste Food, paper, Plastic etc.. Agricultural waste Straw, Wood etc Industrial waste Plastic, Tire, Construction material etc Electricity for Grid Thermal Recycle!! Cold Water for Air Conditioning Material (Slag, Ash for cement) Steam/Hot Water for Process Water for Drinking & Irrigation

16 Japan A country not rich in natural resources Long history in WTE ever since 60 Systematic infrastructure from waste collection to recycle to ELECTRICAL, THERMAL, MATERIAL etc.. Advanced key technology for energy conservation and global warning Recycl e Pollution Control Safety Reliability Environment Protection

17 総発電電力量 (MW) WTE (Electricity) Target in Japan Electrical power generation(mw) 3,000 2,500 Need to install even higher efficient WTE plant. 2,500 2,500 2,000 1,500 1,192 1,246 1,365 1,441 1,491 1,512 1,590 1,604 1, 平成 年度平成 年度 2002 平成 14 年度平成 年度平成 年度平成 年度平成 年度平成 年度 Resource: Ministry of Environment 平成 24 年度

18 WTE System Advantages Improve residential environment and health Clean, well treated exhaust gas. Better solution compared to land fill. Waste volume reduction to less than 10% Land fill for longer life or10% ash for cement industry Substitute fossil fuel Improve national energy security & Energy conservation GHG reduction (about 50% CO2 free) Dedicate to Global Warming Less fluctuate renewable energy resources Good for the base load operation for Smart Grid Waste to Energy & Material Electricity, Water, Cold/Hot water, Steam, Ash and Slag 18

25 Constituted Technologies 1. MED Desalination System 2. Waste to Energy (WTE) System 3. Concentrated Solar Power (CSP) System (Optional) 25

26 Concentrated Solar Power (CSP) Plant Parabolic Trough Type Solar Thermal Plant 26

27 What is CSP technology? CSP is the power generation plus the desalination system as a case may be by using high-temperature heat obtained from solar energy. To convert the sun s energy into high-temperature heat, mirror/reflector is used and sunlight is concentrated near the focus of mirror/reflector. High-temperature heat can be converted into electricity and water. 27
