Flexible Feedstock

REC facilities will accept a variety of feedstock including:

  • Paper, cardboard, cellulose

  • Waste plastics

  • Separated Municipal Solid Waste (MSW)

  • Waste oil

  • Sawdust or wood waste

  • Mesquite, cedar, lawn trimmings

  • Dried manure and sewage

  • Straw, agricultural waste

REC's ability to convert this variety of feedstock into distinct energy and industrial products — recycled naphtha, diesel fuel, carbon dioxide and activated carbon — offers flexibility to sustain production, adapt to market pressures and optimize output to meet consumer demand as no other waste–to–energy facility currently does.

Flexible Fuel
REC’s technology produces liquid products in the middle distillate range as shown in the graphic. REC can make products such as diesel fuel, kerosene, and naphtha.


The feedstock used during conversion determines if the finished product is a petroleum-based fuel or a biofuel.

Waste plastic as a feedstock originates from petroleum naphtha. If we choose to make a light middle distillate fuel or chemical from waste plastics, we might choose to recycle waste plastics back into naphtha. The naphtha that is produced from recycled plastics might be called "recycled naphtha".

If the feedstock comes from cellulosic materials such as sawdust or wood waste, then the end product would be called “renewable diesel fuel” because the feedstock is a renewable source. Or if we made naphtha from cellulose it might be called “bio naphtha”.
