Energy
In 2017, we and our partners generated over 200,000 Megawatt-hours of renewable electricity. That is enough to power over 27,000 New England homes.
Here are some of the ways we and our partners produce renewable energy:
Landfill Gas to Energy
Waste in our landfills gradually decomposes and produces landfill gas, which we can capture and use to power engines. Producing electricity from landfill gas protects the climate twice: it keeps heat-trapping methane out of the atmosphere and it replaces fossil fuel based power generation.
Anaerobic Digestion
Waste can also decompose into methane gas in facilities called anaerobic digesters, often located on dairy farms or at wastewater treatment plants. We deliver food waste to these facilities, which produce electricity and return valuable organic nutrients and carbon to the soil.
Landfill Heat Recovery
Our North Country Landfill uses geothermal loops to recover thermal energy from the landfill to warm their maintenance shop. The innovative project offsets fossil fuel combustion and is thought to be the first of its kind in North America.
Landfill Solar Farm
The open acreage around many of our facilities is well-suited to host solar panels as another source of renewable energy. The 12-acre solar array we host at our landfill in Coventry, VT is an example of this.

Since our last report, we have continued to invest in our landfill-gas-to-energy systems by installing over 150 gas collectors and 40 acres of cap across nine locations. Our energy development efforts at the remaining three active target landfills have been delayed by challenges such as a lack of grid capacity and low natural gas and electricity prices.

Energy recovery fits into our broader resource renewal vision. In the coming years, we will continue to advance landfill gas to energy, anaerobic digestion, landfill heat recovery, solar energy, and innovative new forms of energy capture at our facilities.

CASE STUDY: North Country Landfill SEED Park
Fresh local produce is rare to see during the winter months in northern New Hampshire. But at the North Country Landfill in Bethlehem, NH, spinach, kale, and strawberries can grow in February.

For a few years now, an innovative geothermal heat loop installed in the base of the landfill has been providing warmth to the maintenance shop, saving over 1,000 gallons per year of heating fuel. More recently, the North Country team has added a small on-site greenhouse, which grows fresh produce and serves as a classroom resource for local elementary school students.

The greenhouse is now a stop on the landfill tour, inspiring visitors to stop and think about all forms of waste and the many innovative new ways we could transform waste into resources.

This is only the beginning. The North Country team has its sights set on an even more exciting opportunity. They're working on upgrading the site's landfill gas into renewable natural gas (RNG) suitable for pipeline injection and vehicle fuel. The project is working its way through approvals and is slated to come online in 2019.
