Bioenergy and Waste-to-Energy

Earth Systems recognises the growing importance of the biomass and bioenergy sector for renewable energy production and carbon capture benefits. With experience in sustainable biomass production, bioenergy plant design and carbon credit generation, we have the capacity to assist you in all aspects of developing your bioenergy / waste-to-energy project.

Earth Systems has in-house engineering design expertise in thermo-chemical processes. We have the capacity to develop bioenergy or waste-to-energy solutions specific to individual project circumstances. We are familiar with all of the most common commercial bioenergy options, including combustion, pyrolysis and gasification processes as well as a variety of applicable power cycles such as steam, ORC, Otto, Diesel, Stirling and tri-generation options. In addition to project design, we can provide independent assessment of the technical merits of a third-party technology solution to assist project developers in minimising technical risk.

Earth Systems is not affiliated with any particular supplier, and therefore we are able to provide independent, objective advice and non-biased comparisons of proposed bioenergy technology.

Services Provided

Our bioenergy / waste-to-energy services include:

Experience and Expertise

Earth Systems personnel have worked with the private sector, governments and research organisations to develop solutions for sustainable use and supply of energy. Relevant experience includes:

  • Feasibility Study for a medium scale bioenergy plant as part of the bushfire recovery program utilising burnt wood residues through an ORC (Organic Rankine Cycle) process for power and heat generation for a bush fire affected town.
  • Government project involving a slow pyrolysis reactor design for the production of biochar in the objective of disposing unwanted willow trees.
  • Government project for beneficial reutilisation of biosolids via hydrothermal processing of the wet biomass.

Report for The International Network for Acid Prevention

26 May 2020

Earth Systems in collaboration with Okane Consultants, released a report providing new insight into ensuring low polluting mine operations, and more successful mine closure outcomes.

The report reviews conventional mine rock stockpile construction methods, and summarises improved construction technologies that are available to help improve water quality from mine wastes. Continued efforts to implement these technologies will help quantify their environmental and economic benefits.
