C.A.R.E. Project Profiles

300 kg/h and 2000 kg/h (2 MWe) pyrolysis plant for char and CHP production, B.E.S.T. Australia (2005-2007)

Biodiesel scrubber and 300 kWe gas engine, Gosford, Australia (2006)

Project background

C.A.R.E. Ltd. has been working with Biomass Energy Services and Technology Pty Ltd. (B.E.S.T.) on the development of a fixed bed paddle pyrolyser for the conversion of papermill sludges, wood wastes, chicken litter and MSW derived wastes to a char product and a pyrolysis gas suitable for heat, power and combined heat and power generation.

Project summary

C.A.R.E. Ltd. has been working with B.E.S.T. in:

  • the design and specification of the existing pilot plant's thermal/catalytic tar cracker,
  • use of hot gas filtration to remove particulates after the tar cracker
  • advice on gas scrubbing and sampling for tars and particulates
  • the use of the pyrolysis gas in a 300 kWe dual fuel diesel engine and
  • the recovery of the byproduct char for use as a soil amendment, fertiliser and soil improver. 

C.A.R.E. Ltd. has also developed design models for scale-up of the technology to 4 t/h of dried input biomass to the pyrolyser.  C.A.R.E. Ltd. has helped to design the  pyrolysis kiln by improving existing design models; provided advice on hot gas filtration, tar cracking and also advised on engine selection, performance and operational conditions.  The plant at Gosford processes wastes for the production of a combustible gas which is used for power generation and the heat used for the drying of wood sawdust and wastes with use onsite.  Byproduct char, commonly referred to as ''biochar'' is used for soil applications and R&D testing.


The technology is being offered by B.E.S.T. commercially at 2 t/h and 4 t/h in the USA by BEST Energies and in Australasia and the Pacific Rim by Pacific Pyrolysis Pty.
