An environmentally and socially responsible Company commercially producing bio-crude oil and micro-algae based, wild harvest replacement products and hydrothermal liquefaction technology.


Our Corporate mission is to safely, ethically and commercially; convert waste into oil replacements, grow microalgae, and sell hydrothermal liquefaction services and equipment.


Muradel is a proprietary Company limited by shares, founded in December 2010 by the University of Adelaide, Murdoch University and the majority shareholder SQC Pty Ltd, which is solely funded by Aban Australia Pty Ltd (part of the Ausker Group of Companies).

The Muradel Demonstration Plant (MDP) in Whyalla, South Australia, was funded by shareholders and a grant of AUD $4.4 million from the Australian Renewable Energy Agency’s (ARENA) Advanced Biofuels Investment Readiness program (Funding Agreement number Q00150). Construction began in late 2013 and the plant, staffed by experienced, technically trained operators, became operational in mid 2014.

Muradel Demonstration Plant

The Muradel Demonstration Plant (MDP) at Whyalla, South Australia, was constructed during the first half of 2014, and commissioned in July 2014. The MDP was officially opened on the 31 October 2014 by the Hon Geoff Brock, Member for Frome, Minister for Regional Development and Minister for Local Government in South Australia, and the Whyalla City Council Mayor Jim Pollock.

Muradel provides a unique approach to sludge and biosolids management for the wastewater treatment industry. Our Green2Black™ solution combines proprietary technologies to sustainably manage sludges and biosolids producing a unique range of marketable products. Green2Black™ has a small footprint and can be co-located at wastewater treatment plants where sludge can be continuously fed through the process and converted into sustainable oils, inorganics and water. The available market for Green2Black’s products is dependent on the composition of the sludge and will be evaluated on a case by case basis.

Our hydrothermal liquefaction technology is available for purchase or lease and we are open to cooperative arrangements with partner or purchaser organisations to develop capabilities with other feedstocks or products.

The microalgae research and development work of SQC Pty Ltd is being continued under the operations of Muradel at the MDP. Freshwater and marine species have been grown with a view to commercialisation. Current research is investigating the use of microalgae to polish human effluent waste water, ready for reuse or environmental discharge. We are researching the commercialisation of bio-products thus produced, currently for bio-plastics but potentially for agricultural soil ameliorants, fish feed, bio-crude oil and other products.


The bio-crude technology developed and deployed by Muradel is innovative and provides a novel pathway for production of renewable biofuel; a pathway that does not compete with agriculture for nutrients or water and does not involve land-use change.

The Green2Black™ technology platform used for processing sludge consists of three main continuously operated processes: pre-treatment (thickening), conversion (hydrothermal liquefaction), and post-treatment (fractionation and extraction). Pre-treatment develops uniform particle size (in the case of biosolids) providing a slurry of ~30% w/w solids. The conversion process takes place in a sub-critical water reactor operating at ~350oC and ~200bar, where hydrothermal liquefaction of the organic content occurs producing hydrocarbons. The resultant reactor product is termed kerogen, which is a combination of hydrocarbons, inorganics (particulate and soluble), water and CO2. Fractionation of the products occurs in the post-treatment processes, producing biocrude oil, fertilizers, pure CO2, lightweight aggregates and water. Typically 60% of the organic fraction is converted into biocrude oil. The biocrude oil is chemically identical to fossil crude oil. A dry weight tonne of sludge at ~80% w/w organic mass will convert into ~3 barrels of renewable biocrude oil, with an energy content of ~30MJ/kg.

The suite of patents associated with the Green2BlackTM technology provides surety that the technology has the potential to be licensed nationally and internationally in urban, rural and remote locations.

Microalgae technology is being developed to commercially produce a number of bio-products. Our most promising current micro-algae research is to scale-up production of proteins for the specialty bio-plastics market. We hope to move into commercial production soon.

Partnerships and Commercialisation

Muradel welcomes commercial, research and institutional investment partnerships to undertake research and/or to develop commercial production using our extensive demonstration plant resources.

Our hydrothermal liquefaction using a Sub Critical Water Reactor is an exciting young science and we can upgrade this technology to meet customer feedstock and product requirements.
