  • Engineered to integrate with existing feed systems without requiring major equipment changes.

Fuel Engineering Without Operational Burden

ReKiln Fuels® manages fuel engineering end to end so your team can focus on running your operation.

Reworld manages:

  • Material pickup and transportation, if requested
  • Fuel engineering and formulation
  • Blending and consistency management
  • Quality assurance against performance targets
  • Regulatory and compliance considerations tied to fuel use
  • Ongoing optimization as inputs or requirements change

Waste producers focus on:

  • Core operations and
    day-to-day business priorities
  • Strategic sustainability and ESG goals
  • Reviewing outcomes and progress, not managing execution
  • Making informed decisions using verified data

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

ENGINEER

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 Fuels FAQs

Straight answers to common questions about ReKiln and alternative engineered fuel.

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

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.

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.

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.

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

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