- Foam insulation
- Low Chlorine Plastics Flake
- Tire and Rubber Waste
- Biomass
- Tissue

Did you know?
Typically, 10% to 20% of an end user customer’s fuel is made up of alternative engineered fuel. However, some kilns use as much as 30%, and usage is expected to rise to 50% and beyond in the next three to five years!

A waste-to-fuel company that makes an impact
Every year, our solutions help businesses and communities avoid approximately 41 million metric tons of greenhouse gas emissions, which is equivalent to the impact made by half of all utility-scale solar installations within the United States.
How we prioritize healthy people, safe workspaces, and a thriving planet with alternative fuel services
-
Safety
Waste is carefully and completely destroyed, eliminating hazards that harm ecosystems, threaten communities and negatively impact plant, animal and human health.
-
Profitability
Waste is effectively and economically separated into recoverable components or processed into a customized fuel product, offsetting raw material costs, opening channels for new revenue and spurring material rebates.
-
Sustainability
Waste is efficiently and environmentally destroyed and transformed into low-carbon fuels, creating cycles that optimize resource value, reduce carbon footprints and regenerate ecosystems.

Alternative Engineered Fuel FAQ
Alternative engineered fuel (AEF) is a sustainable fuel created from non-recyclable industrial and post-consumer waste materials. It is processed to meet specific energy and emissions standards and used as a substitute for fossil fuels in industries such as cement and lime manufacturing, power generation, paper production and other high-energy applications. These alternative fuels help businesses reduce landfill waste, meet environmental and operational goals, and advance toward a circular economy.
Alternative engineered fuels can be made from a wide variety of unavoidable, non-recyclable materials. Some common sources include:
- Thin film plastic and low chlorine plastic flakes.
- Waxy cardboard and paper.
- Foam insulation and packaging scrap.
- Tires and rubber waste.
- Leather, wood, crops, and other biomass.
- Textiles, fabrics, and fibers.
Although the creation of alternative engineered fuel takes a number of variables into account, when simplified, the process typically involves:
- Waste Assessment and Collection: Waste is profiled and assessed, and non-recyclable materials suitable for waste-to-fuel conversion are identified.
- Pre-Processing: Contaminants are treated and / or removed and the materials that will be used for fuel production are prepared.
- Shredding and Blending: The particle size and energy content of the fuel is optimized to meet end-use requirements.
- Quality Control and Delivery: The fuel is checked to ensure it meets all industrial and regulatory specifications before it’s distributed to the facilities that will use it.
There are two categories of customers that benefit from alternative engineered fuel solutions—generators and end users.
Generators consist of businesses from every industry. They are the companies that create the waste used in AEF production. They’re typically looking to divert their non-recyclable waste from landfills to avoid compliance and environmental risks, improve their carbon footprints, and create value from their otherwise “useless” materials. They could be manufacturers trying to solve for off-spec products, distributers managing complex packaging scrap, or nearly any other case.
End users, on the other hand, are the companies that purchase and use the final AEF product. They aim to replace the coal, oil, gas, etc. that their operations rely on with this customized, low-carbon fuel. Through it, they can meet their emission goals while using a product that is more efficient (and oftentimes more affordable) for their systems. End users make up a smaller pool of customer industries when compared to generators and typically consist of those with cement or lime kilns, power plants, industrial boilers, pulp and paper mills, or some other energy-intensive assets that have traditionally relied on fossil fuels.
Alternative engineered fuel provides several key benefits for businesses and the environment. First, it helps divert waste from landfills by converting non-recyclable materials into a valuable fuel source, reducing landfill dependency. By replacing traditional fossil fuels, AEF also lowers greenhouse gas emissions, contributing to a reduced carbon footprint and improved air quality.
Additionally, AEF serves as a sustainable energy source, offering an environmentally friendly alternative to coal and other conventional fuels commonly used in industrial processes. Businesses that adopt AEF can also experience cost savings by reducing landfill disposal fees while utilizing a competitively priced fuel option that is customized to their specific system needs. From a regulatory perspective, AEF helps companies meet sustainability targets and comply with environmental regulations related to waste reduction and energy efficiency. Lastly, AEF promotes resource efficiency by maximizing material recovery, ensuring that waste materials are repurposed rather than discarded.
