Renewable Energy

Grand Central Landfill is managing more than 3,000 cubic feet per minute of landfill gas. This gas is collected and removed through a series of wells located throughout the landfill. To install a gas well, special equipment is used to drill into the waste and a pipe with holes, surrounded by gravel, is inserted to collect the gas flow. The wells are all connected to a central header pipeline, where the gas is channeled to a flare for combustion.

With its relatively high energy content, landfill gas represents a low-cost fuel that can be used to power electrical generators. Managing this byproduct as a “green” energy source offers the opportunity to capitalize on an alternative source of electrical power.

With a large and growing number of beneficial-use gas projects around the country, Waste Management is a nationwide leader in turning landfill gas into electrical power. The company has 124 landfill gas to energy related projects operating in 19 states.

Today’s modern, engineered landfill is an environmentally sound system for waste disposal. Landfills offer a clean, renewable energy resource that is generated continuously through the decomposition of the waste. This resource is known as landfill gas.

Landfill gas is a naturally occurring byproduct of the waste thrown out every day. Each person in the United States generates about 4.5 pounds of waste per day, and more than 50% of this waste is managed in municipal solid waste landfills such as Grand Central Landfill. Organic materials disposed of in a landfill- including food and sludge from the wastewater treatment process- help to promote the decomposition process. Landfill gas typically consists of about 50% methane and 50% carbon dioxide.

Instead of simply flaring the gas, Waste Management uses this gas in a variety of applications to create green energy. Grand Central partners with the Green Knight Economic Development Corporation to turn landfill gas into electricity.

The Green Knight Energy Center and Grand Central manage:

  • 230 gas extraction wells located throughout the site
  • 3,000 cubic feet per minute of landfill gas

The facility generates enough energy to power nearly 7,000 homes and replace 100,000 barrels of oil each year. With a large and growing number of beneficial-use gas projects around the country, Waste Management is a nationwide leader in turning landfill gas into electrical power. The company has 136 landfill gas to energy related projects operating in 19 states.
