Turning Hard-to-Recycle Waste into Value

Challenging waste streams don't have to end up in a landfill. We can transform a wide variety of waste materials into alternative engineered fuel. Some of the most common streams of post-recycled waste 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

The Perfect Blend for Kilns

Not all waste burns the same. Fuel performance depends on what the material is made of, how it behaves under heat, and whether it aligns with the operating requirements of the end user.

ReKiln Fuels™ starts by assessing the inputs so fuel can be engineered to perform predictably.

  • Material composition and variability
  • Energy content and burn characteristics
  • Compatibility with kiln or system specifications

Fuel is Built, Not Found

Once materials are assessed, Reworld™ engineers alternative fuel to meet defined performance targets. This is where waste becomes a usable input, not a liability.

Fuel formulations are designed to deliver consistent energy content, predictable combustion, and compatibility with the end user’s system.

  • Fuel formulation based on target energy performance
  • Blending to manage variability and consistency
  • Quality controls to meet end-user specifications

Alternative Fuel FAQs

Straight answers to common questions about alternative engineered fuel.

What is alternative engineered fuel (AEF)?

AEF is a combustible industrial fuel made from non-recyclable, non-hazardous solid waste and engineered to meet defined performance specifications for industrial use.

What types of waste can be converted into AEF?

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.

Which industries can benefit from alternative fuel services?

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.

How is ReKiln Fuels® different from Waste-to-Energy?

ReKiln Fuels® produces a physical fuel that is consumed directly in industrial processes like cement and lime kilns. Waste-to-Energy systems generate electricity and/or steam that is used to power homes or businesses.

Will ReKiln Fuels® work with existing equipment?

ReKiln Fuels® are engineered to integrate with existing feed systems. Most programs do not require major equipment changes, though compatibility is assessed upfront.

How consistent is the fuel performance?

Fuel is engineered to deliver predictable energy content and combustion characteristics based on end-user specifications, with quality controls in place to manage variability.
