Enerdyne Power Systems, Inc.
Staying Ahead of the Power Curve
Enerdyne Power Systems, Inc., is an LMOP Industry Partner in North Carolina
that develops, owns, and operates facilities for collecting and using
landfill gas. Enerdyne has achieved great success by tailoring gas collection
and delivery systems to meet customers’ needs. Enerdyne’s
distinct clientele—primarily composed of organizations that have
voluntarily installed gas collection and gas use facilities on their landfills—include
both private and public landfill owners and operators. Enerdyne also partners
with other companies to implement innovative, state-of-the-art projects
using landfill gas. For its efforts and commitment to landfill gas use,
the U.S. Environmental Protection Agency (EPA) recognized Enerdyne as
a Landfill Methane Outreach Program (LMOP) Industry Partner of the Year
in 1999.
Enerdyne has participated in a variety of landfill gas initiatives,
including:
- Solar turbine project at the Hanes Mill Road Landfill in Winston Salem,
North Carolina, with a capacity of 4.6 MW. The power is sold to Duke
Energy and the project also plans to sell steam to a nearby Sara Lee
Hosiery Plant.
- Boiler-burner control gas delivery system for Pitt County Memorial
Hospital in eastern North Carolina that allows for a seamless transition
between natural gas and landfill gas, depending on their relative availability.
This is a unique application for simultaneously co-fueling a small package
boiler.
- Landfill gas transmission from the Cumberland County Landfill in Fayetteville,
North Carolina, to a Cargill soybean processing plant.
- Gas collection and delivery systems for two landfills in Catawba
County, North Carolina. The county purchased internal combustion engines
with generators to produce electricity, which is sold to Duke Energy
and fed into the public power network.
- Gas venting system retrofit to prevent migration of landfill gas
in Iredell County, North Carolina. The landfill operators are currently
flaring the gas until the local utility approves delivery of the gas
to customers. The gas will then be supplied to Uniwood Paper, an International
Paper facility, nine miles away.
- Landfill gas-fueled sludge incinerator for the Metropolitan Sewerage
District (MSD) of Asheville, North Carolina. Enerdyne helped MSD set
up a system that mixes landfill gas with methane gas from sewer digesters.
This mix of gas then helps dry the sludge in a fluidized bed incinerator,
and the residual landfill gas fires two Waukesha engines that reduce
in-plant power needs, especially during peak hours.
Enerdyne’s landfill gas projects have three primary benefits:
environmental improvement, economic development, and educational outreach.
Environmental benefits include the reduction of methane emissions to
the atmosphere, which contribute to global climate change. Economic development
is especially apparent in Asheville, where reduction of landfill and wastewater
odors preceded a housing boom and has led to the development of an 18-hole
golf course on the landfill property. Providing public education and addressing
public concerns about landfill projects has also proved beneficial to
Enerdyne’s efforts. The Catawba County project, with sound levels
below normal operation decibels, is deemed neighbor-friendly. The Asheville
project, having greatly alleviated odors, has also fostered good will
among neighbors. These examples of how landfill gas use can be successful
and unobtrusive might encourage the public to support similar project
development in the future.
Summary of Benefits
- Generates clean, renewable energy
- Reduces greenhouse gas emissions from landfills
- Contributes to local economic development
- Performs educational outreach by setting neighborhood-friendly
examples
What Is Landfill Gas?
Most of the waste we generate ends up in landfills,
where it decomposes and produces landfill gas. Landfill gas, if
uncontrolled, can contribute to local smog and present health and
safety hazards. Additionally, landfill gas is approximately 50 percent
methane, a potent greenhouse gas that contributes to global climate
change. Methane, however, is also a reliable and renewable fuel
source that can be collected an used in a variety of applications. |
LMOP is a voluntary program that assists project developers, utilities,
landfill owners/operators, energy users, and communities to encourage
new LFGE projects. LMOP has developed a variety of tools (e.g., profiles,
fact sheets, project development manuals, and software) to facilitate
the development of LFGE projects. Hundreds of landfills across the country—and
around the world—are good candidates for a LFGE project. To find out more, please contact LMOP.
