Commercial technology partner

The PDC has extensive experience in producing CNF or highly refined cellulose, from a wide variety of feedstocks, processing conditions and pretreatments using our patented and licensed technology.

We have processed material for dozens of companies. Come work with us or send us your material. We can process dry or wet materials, from as little a 0.5 kg up to 350 pounds (all on a dry basis).

Feedstock Versatility:

  • Hardwood and softwood pulps, wood chips, wood residuals, non-woody biomass

Processing – Mechanical Refiners

  • The PDC has both double-disk and conical refiners. Our newest system includes Valmet’s DD6700 double-disk series and Valmet’s OptiPro conical refiner. These are commercial scale refiners, requiring at least 600-800 pounds (dry) weight of material to run.
  • The PDC also has a Regmed 6″ lab scale refiner for smaller batches, typically 50 liters.

Tailor Processing to Dial-in Properties

  • A Morfi analyzer and Valmet’s FS5 Fiber Image Analyzer is used to monitor CNF production. CNF can be made to a variety of fines levels to change properties.
  • Pretreatment options can be included in production

Scale-up

  • Lab scale supermasscolloider enables small quantities to be pre-evaluated prior to scale-up

Capacity

  • 1-2 ton per day capacity, depending on material
  • Over 30 tons of CNF produced, over 250 runs completed
  • 3% slurry or 20% cake product available
  • Off-site pilot spray dryer
