Dr. John Sanderson

B.Eng (Chem), PhD.

Principal Environmental Engineer

Energy, Greenhouse Gas and Bioenergy Specialist



John Sanderson holds the position of Principal Environmental Engineer with Earth Systems.  In this role, John provides specialist technical and engineering consulting on biomass and bioenergy technologies and projects, including the emerging field of biochar and conducts greenhouse gas and energy audits to comply with the relevant regulations and standards.

After completing his PhD in 2003 John worked as a postdoctoral fellow for the CRC for Clean Power from Lignite, developing practical control strategies for operational issues in lignite gasification, and as a research engineer for CSIRO Minerals, providing engineering research, design and consulting services to the minerals processing industries.

John has extensive experience in biomass combustion and gasification systems, having developed the small 15kWe Tasman gasifier for remote/developing regions, and undertaken recent feasibility studies on a bioenergy power plant utilising burnt wood residues, a transportable biochar machine for woody weeds and an energy recovery process for the beneficial reuse of biosolids from municipal wastewater treatment.  John currently leads the proof of concept design team working on the commercialisation of the mobile biochar machine for a Victorian Government authority.

  • Designed a fluidized bed carbon-cooler as part of the activated carbon regeneration process at an Australian gold mine.
  • Undertook a comprehensive review of waste heat recovery prospects for the Australian minerals processing industry.
  • Conducted a feasibility study on a 1MWe Bioenergy power plant utilising fire-damaged timber in the Marysville region.
  • Conducted a feasibility study on the technical and economic merits of a mobile device for producing biochar from woody weed residue associated with catchment management operations. Currently managing proof-of-concept and prototyping for product commercialisation.
  • Developed a calculation methodology (system carbon mass balance) and assumptions to estimate GHG emissions abatement potential of a proposed algal biodiesel process for a commercial client.
  • Undertook a detailed review of energy consumption trends and energy efficiency opportunities for corporate datacentres.
  • Designed, installed and commissioned  15kWe/100kWth wood gasifiers atUniversity of Ulster,Northern Irelandand Knetic Renewables, Gold Coast.
  • Conducted a feasibility study on the gasification of waste-wood from a transfer station to provide heat for a municipal swimming pool in regionalVictoria.
  • Undertook a feasibility study on catalytic hydrothermal processing of biosolids for energy production and volume reduction at an Australian wastewater treatment plant.
