Waste-to-Energy: Turning Trash into Power and Cutting Carbon
Back in 2011, the U.S. faced a growing need to manage waste while cutting emissions. Enter Waste Management’s Waste-to-Energy (WTE) solution—a smart way to reduce landfill gas to energy (LFGTE) use and generate electricity at the same time.
While landfills still served a purpose, WTE technology offered a cleaner alternative. Instead of burying garbage, Waste Management used advanced combustion to convert non-recyclable waste into usable power. This process dramatically cut greenhouse gas emissions while generating electricity for thousands of homes.
From Maine to Florida: WTE Gains Ground
The state of Maine, for instance, led the way. With limited landfill space and long winters, Maine invested in waste-to-energy plants early on. These facilities helped cut costs, improve energy resilience, and reduce methane—a potent greenhouse gas—from landfill decomposition.
Meanwhile, in Florida, Waste Management’s Wheelabrator facilities turned everyday trash into electricity. In just one year, these sites produced enough energy to power more than 400,000 homes. The results were clear: less waste, fewer emissions, and more renewable power.
Here’s an overview of the process, if you’re looking for more info. Also, if you’re interested, here’s an example of how LFGTE powers the University of New Hampshire.
Why Waste-to-Energy Matters
First, WTE isn’t just about power—it’s about pollution control. Compared to methane-leaking landfills, WTE plants offer tighter emissions standards and better air quality monitoring. Filters and scrubbers capture harmful pollutants before they leave the stack, helping communities breathe easier.
Second, this technology reduces our dependence on fossil fuels. By converting waste into energy, WTE plants offset coal and natural gas use. This shift not only shrinks our carbon footprint but also provides local energy from local sources—keeping costs down and reliability up.
Lastly, WTE supports a circular economy. It doesn’t compete with recycling. In fact, WTE plants only burn what can’t be recycled, meaning these systems reinforce smarter waste sorting and better material recovery upstream. For example, WM’s full range of renewable energy technologies enables it to currently produce two to three times more energy than the entire solar industry.
Waste Management’s Commitment to Innovation
Back in 2011, Waste Management operated more than a dozen WTE plants through its subsidiary, Wheelabrator Technologies. These facilities processed over 7.5 million tons of waste each year and produced roughly 630 megawatts of clean electricity.
Even more impressive, the leftover ash was used in road construction and other applications, keeping the full lifecycle of waste out of landfills. Waste Management didn’t just burn waste—they turned it into opportunity.
The company also pushed for broader education and public understanding. Through facility tours, classroom materials, and partnerships, they showed how trash could become a resource—not just a burden.
A Cleaner, Greener Future Starts with Trash
In a time when clean energy options were expanding—solar, wind, and efficiency gains—WTE stood out for its double-duty approach. It helped tackle two problems at once: too much waste and too many emissions.
Of course, no energy source is perfect. But compared to traditional landfills, WTElandfills are beneficially reused as wildlife habitats and recreational areas for the local neighborhoods. So the facilities presented a safer, smarter solution. They offered an energy bridge between the fossil-fueled past and a renewable future.

WM also converts this methane into liquefied natural gas (LNG) and compressed natural gas (CNG), in order to fuel its truck fleets. For example, WM’s Altamont Landfill’s LNG produces 98% fewer emissions than diesel fuel, making LNG the lowest carbon fuel available.
