REDUCED LIABILITY

Using wastes as alternative fuels in cement kilns is the EPA’s highest rated and approved technology for energy bearing wastes. Cement kilns have the highest waste destruction rates at above 99.999%. Wastes are destroyed most effectively in cement kilns because they are exposed to temperatures above 2600°F and with long residence times. This combination means all the waste is used as energy and there is no waste left as residual ash being sent to landfill. Cement kilns are the preferred thermal treatment process for recovering energy from carbon rich industrial wastes.

WASTE AS ENERGY

We do more than dispose of your waste. We put it to work as energy to make cement. Cadence developed the use of Chem-Fuel® using industrial wastes to replace the use of non-renewable resources as fuels for use in cement kilns. We’ve been identifying carbon-rich wastes to use in our Chem-Fuel° program since 1975. We now supply almost 200,000 tons of coal replacement fuels annually to the cement industry with primary supply to Ash Grove Cement.

COST-EFFECTIVE DISPOSAL

Ash Grove and Cadence have more than 35 years’ experience working exclusively together and constantly developing our hazardous waste-derived fuel operations. The two fully-permitted RCRA Part B hazardous waste combustors are centrally located in Foreman, Arkansas and Chanute, Kansas. Using wastes as fuels is good for our environment and makes the US cement manufacturers more competitive by reducing their operational cost. Our joint experience, plant locations, and technology makes us the most efficient and lowest cost option to our customers.

CONSERVE RESOURCES

Your waste will NOT be wasted. Our sustainable practices use the carbon content in waste to replace non-renewable fossil fuels. One ton of waste on average replaces one ton of coal used to heat the kiln. Cadence aids in the conservation of 125,000 tons of coal annually. Together both Cadence and Ash Grove Cement have reduced coal usage by over 3 million tons since 1986 when we began working together.

INDUSTRY LEADER

Cadence has 45 years of waste-derived fuels experience. We were the first to use liquid industrial waste in cement kilns as an alternative energy source. Our leadership pioneered the use of alternative fuels and has been involved in developing this industry since the 1960s. Since exclusively joining forces with Ash Grove Cement, Cadence is and has been the exclusive supplier of hazardous waste derived fuels to Ash Grove Cement.

Cadence Environmental Energy was the first to provide industrial wastes to cement kilns.
PUTTING WASTE TO WORK - Since 1975

We've been supplying cement kilns with energy bearing wastes for 47 years.
Cadence and our customers have conserved over 3 million tons of fossil fuels.

That's what we mean when we say "Putting Waste to Work" and preserving our natural resources.

CHEM-FUEL

In 1975 Cadence was the first to use carbon-rich waste as fuel in cement kilns.

Today, this fuel called Chem-Fuel® has helped industries large and small manage their hazardous wastes in the most cost-effective and environmentally responsible way possible. Since Chem-Fuel® replaces coal and other fossil fuels, these non-renewable resources can stay in the ground.

Chem-Fuel® is good for the industry and good the environment.

Bulk Liquids (K-Blend)

BULK LIQUIDS (K-Blend)

Roughly half of the liquid waste Cadence receives meets our "kiln-ready" specifications and is sent directly from waste generators to an Ash Grove Cement kiln as part of our Generator Direct program. Waste that does not immediately meet our "kiln-ready" specifications is directed to our national network of TSDF processors also referred to in the industry as “fuel blenders”. Cadence has worked with many of these environmental service providers since the 1970s developing processes and specifications to blend optimal Chem-Fuel® supply for the Ash Grove Cement kilns.

TSDF/FUEL BLENDERS

Thousands of customers across the country work with Cadence approved Fuel Blenders to prepare kiln ready fuel for Ash Grove Cement.

TSDF/Fuel Blenders

What are the benefits?

NEARBY

Most processors in the Cadence network are conveniently located in the proximity of major manufacturing centers throughout the country. That means wherever you are, there will likely be an experienced processor close by.

VERSATILITY

Processors can accept a wide variety of Btu-rich, carbon-based waste. Chances are good that the waste you generate can be processed into Chem-Fuel®. If your waste is greater than 5,000 Btu/pound - liquids, sludge and/or solids - it can be processed into Chem-Fuel®.

CONVENIENCE

Our waste processor network can accept your waste in any amount in the way most convenient to you - rail, bulk, roll-offs and/or drums. As part of our service, a Cadence team member will work with you to identify which of your hazardous wastes streams can be included in the Chem-Fuel® program.

PROFESSIONAL

Chem-Fuel® Processors in the Cadence network will manage your waste properly according to all applicable Federal and State regulations.

Wastes not meeting “Kiln-Ready” specifications can be routed to a Cadence approved TSDF Fuel Blender for further processing. Either way, waste generators save time and money and have the assurance that 100% of their waste will be used in Ash Grove's fully permitted state-of-the-art cement kiln.

One-hundred percent of the waste is used.

REPURPOSING WASTE AS RAW MATERIALS

We want your waste to make cement

To make Portland cement, huge amounts of lime, calcium, silica, iron, alumina are used as raw materials. These key ingredients are also found in a wide variety of industrial wastes from boiler ash to spent filter cakes - from treated waste water to foundry sand. Typically, these materials are sent to landfills.

WE HAVE A BETTER WAY

If you generate these types of wastes, Cadence can help you reach your sustainability goals by repurposing these wastes as raw materials in an Ash Grove cement kiln. Cement kilns require huge amounts of these raw materials so, however much you generate Ash Grove can reuse your waste to make cement. When wastes are safely incorporated in cement they are gone for good and so is your long-term liability.?

  • Filter Cakes
  • Bauxite
  • Foundry Sand
  • Mill Scale
  • Ceramics
  • Bottom Ash
  • Slag
  • Catalysts
  • Sludges
  • Silicate
  • Kaolin
  • Abrasives or other similar wastes...

We want to use it as an alternative raw material to make cement.

One call to Cadence is all it takes. You generate the waste, we handle the details. It couldn’t be easier, more cost effective or more environmentally friendly.
