WASTE TO ENERGY CONVERSION
Power CogenerationWaste to EnergyAdvanced W-to-E
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

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 energy—enough to support
45,000 homes Waste is combusted in furnaces using refuse
derived waste (RDF) technology at > 980 oC Reduce the original waste to 10% as residual ash Upgraded pollution control systems ensure both
particulates and NOx to meet or exceed all state and federal emission standards.

INTEGRATION OF RENEWABLE ENERGY INTO PUBLIC FACILITY DESIGN
LandfillDesalination Plant
Energy Storage
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 LandfillSan Antonio, Texas, USA
Hickory Ridge LandfillAtlanta, Georgia, USA
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.

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
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 1973. • The 1,872-megawatt plant utilizes 6 vertical Francis-type pump
units
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
