28 WASTE TO ENERGY CONVERSION Power Cogeneration Waste to Energy Advanced W-to-E

29 Power Cogeneration Convert municipal wastewater to digester gas as fuel with advanced technologies Power a 335 kW cogeneration system digester gas treatment system 335 kW reciprocating engine-generator heat recovery systems two hot water boilers This new cogeneration facility is a critical component to new admin building and its ability to achieve LEED status due to heating and energy from a renewable resource Budd Inlet Wastewater Treatment Plant Olympia, Washington, USA

30 Waste to Energy Conversion Municipal solid waste disposal crises in Oahu 2,000 tons/day of municipal waste sold to local power company Convert waste to energyenough to support 45,000 homes Waste is combusted in furnaces using refuse derived waste (RDF) technology at > 980 o C Reduce the original waste to 10% as residual ash Upgraded pollution control systems ensure both particulates and NO x to meet or exceed all state and federal emission standards. Waste-to-Energy Facility Oahu, Hawaii, USA

31 Advanced Waste to Energy Conversion The Onion Story - Oxnard, California, USA Gill Onion, the largest onion processor in US Generates > 100,000 kg/day of onion peels Reduce waste volume by 75% with 2-stage grinding 20 tons/day of onion cake cattle feed 30,000 gal/day of onion juice (> 60,000 mg/L COD) Digested in a high-rate upflow anaerobic sludge blanket reactor to produce 100 cfm of methane-rich biogas Power two 300 kilowatt fuel cells that generated 0.6 MW of energy to supply >80% of the facility Ground breaking achievement won prestigious Grand Conceptor Award in 2010 from the American Council of Engineering Companies

32 INTEGRATION OF RENEWABLE ENERGY INTO PUBLIC FACILITY DESIGN Landfill Desalination Plant Energy Storage

33 Solar Energy Cover for Landfill Landfills occupy massive open area indefinitely The installation costs of an exposed geomembrane closure are substantially less than a traditional closure Long-term maintenance costs can be replaced with a positive revenue stream Avoid thousands of tons of greenhouse gases that would be emitted from the mowing and soil replacement activities needed for long-term care of a conventional grass-covered cap Rainwater can be harvested without the need for sedimentation and cleaning. Tessman Road Landfill San Antonio, Texas, USA Hickory Ridge Landfill Atlanta, Georgia, USA

34 Hickory Ridge Landfill Solar Energy Cover The 48-acre at capacity landfill was transformed into the largest solar energy generating facility in the world, represents a milestone for landfill final closure The solar energy cover uses >7,000 solar panels to generate more than 1 megawatt of clean, renewable electricity for the local community.

35 Wind-Powered Seawater Desalination Plant in Australia Seawater desalination has become the primary water source for many costal countries. Some desalination plants in UAE, Australia, Spain, and Scotland include wind power in the plants energy portfolio Several desalination plants in Australia built dedicated wind farms along the coastline as part of the projects in exchange for power credits Desalination Plants in Sydney and Perth could obtain enough wind energy credit to cover the entire facility operation. Perth, Australia

36 Energy Pumped Storage, Ludington, Michigan US 20 Billion gal/day of water is consumed in US Delivering water from the water treatment plants to the end users consume tremendous amount of energy Energy Pumped Storage: Treating water during off- peak hours; pump water to an elevated storage facility; then use gravity to re-introduce clean water back to the distribution system when it is needed The city of Ludington by Lake Michigan hosts one of the world's largest pumped storage facilities. 1,000 acres, in operation since The 1,872-megawatt plant utilizes 6 vertical Francis-type pump units

37 Summary With technology advancements in sustainable design, the concept of been green has evolved from a social/political preferred ideology to an environmentally responsible cost saving feature Numerous examples given in this paper clearly suggest that there are opportunities presented in all the phases of building any facility or public infrastructure to conserve and protect natural resources while substantial financial and social benefits can be realized at the same time Being resource efficient and environmentally responsible should not just be a guideline, but rather become the core principle for every Civil Engineer
