We recover and recycle valuable resources such as metals from the waste stream that would otherwise end up in landfills
We use local waste materials as a fuel to produce electricity and steam, reducing dependence on landfills
Every 1 ton of waste converted to energy = 1 ton of carbon dioxide avoided
Here in our waste-to-energy plants, we weigh post-recycled waste delivered from residential, commercial, and special waste customers before transporting it to the tipping floor. Material is visually inspected before being pushed into the fuel bunker. This waste material can vary widely in moisture content and thermal value, so it's continually managed in the bunker to ensure consistency.
Our facilities use local fuel—everyday household and business waste—to generate clean, local energy for our communities
We offer commercial and industrial customers one-on-one staff support to ensure their zero waste goals are achieved and each delivery is executed effortlessly
We are trained in handling sensitive materials such as non-hazardous waste that requires special treatment or handling like assured destruction
Overhead cranes then transfer the trash into a feed hopper to the boiler. Inside each boiler, an inclined, reciprocating, metal grate slowly moves the trash through a thermal (heating) process, where temperatures exceed 2000°F.
As we process post-recycled waste, we reduce waste volumes by 90 percent, conserving valuable landfill space
Temperatures exceed 2000°F
Air is continually drawn from waste storage areas into the boiler, creating a constant negative pressure that prevents the escape of dust and odors
Hot combustion gases pass by a series of boiler tubes filled with water, creating high-pressure steam. The steam is used to drive turbine generators and produce electricity for sale to local utilities. The steam also can be sold to drive industrial processes or for district heating & cooling. We condense the remaining steam into purified water and return it to the system for more renewable energy production.
Heat from the combustion process heats water in boiler tubes to create high-pressure steam
Thermal energy in the form of high-pressure steam is used to drive turbine generators
Plant turbines generate electricity that is sold to local utilities to power communities
As we process post-recycled waste, we reduce waste volumes by 90 percent, conserving valuable landfill space and reducing greenhouse gases. Prior to safely landfilling the inert ash, we remove ferrous metals such as iron and steel, and non-ferrous metals, such as copper and aluminum, from the ash residue and send it to recycling facilities. The remaining 10 percent is ash residue. In the UK, the ash residue is either processed on-site or transported to an offsite facility where metals are recovered for recycling before the remaining ash is used as an aggregate by the construction industry.

After heat in the combustion gas is absorbed in the boiler to produce steam, the gas exits the boiler and powdered activated carbon is injected to remove mercury and trace organic compounds. The gas then enters a spray dryer absorber where lime is combined with the gas to neutralize acid gases, including sulfur dioxide and hydrogen chloride. The gas then passes through a fabric filter where particulates are removed. The cleaned gas exits through the stack after a series of continuous emissions monitors analyze and record levels.
