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
