Calix wins AWA Water Innovation Forum competition

with PROTECTA-MAGTM spray slurry technology.


25 March 2015


As part of last week’s AWA Water Innovation Forum, companies were given the opportunity to pitch their product or service to a panel of judges and event attendees. There were five winners who each receive a 3x3m exhibition booth in the Innovation Corner at Ozwater’15 and a complimentary registration to the conference.


Nittin Apte pitched the Calix innovative spray slurry solution for sewer asset protection against a field of 20 water technologies with great success. The PROTECTA-MAGTM product was received with great enthusiasm at the forum and generated significant interest.


Calix was featured in an article recently published on The Gold Coast Bulletin.

01 March 2015


The article focused on the opening of our new Magnesium Hydroxide Liquid (MHL) production plant at Molendinar in Queensland.


The plant has a capacity of 6000 tonnes per annum per operating shift and can easily scale to grow with our customers’ needs. Using Calix’s unique high reactivity MgO powder as a feed source, the plant is capable of producing a batch of 60% solids MHL in less than 90 minutes, a world first.


Plant manager Troy Marshman said the slurry  product could be bought in quantities from 1,000 litres to a 15,000 litres tanker-load and the plant offered room for expansion.


The Molendinar slurry-making plant will tap demand in northern NSW, southeast QLD and as far as Wide Bay. Calix CEO Phil Hodgson said Calix alss operates a slurry plant in the Philippines and planned more in north QLD, Perth and Adelaide.

Calix Limited Launches a New Business

in South East Asia.

15 December 2014


Calix Limited is proud to announce a joint venture agreement was signed on the 25th November 2014 with Mr JoJo Chan, a prominent business man in the Philippines. The new company ACTI-Mag Asia Inc. was officially incorporated on 1stDecember 2014. 


Following Calix’s first offshore batching plant was trialled in Manila, a facility was developed to produce highly active Magnesium Hydroxide products from our high surface area ACTI-Mag™ Magnesium Oxide, supplied from Calix’s CFC15000 Flash Calciner at our Bacchus Marsh Production Facility in Australia. 

 The Philippine water treatment industry has shown great interest in this exciting new project. Trials have included municipal sewage, food processing, semiconductors, acid mine water, aquaculture and agriculture applications.


ACTI-Mag Asia Inc. will initially produce Active Magnesium Hydroxide for waste water treatment in the Philippines; trials with various Philippine companies in Municipal Waste Water, Agriculture, Semiconductors and Aquaculture are currently being undertaken. Sales are expected to commence during Q1 2015.


Calix looks forward to supplying these different industries with an effective and safe neutralisation agent, building on our success in the Australian market in the rapidly developing Philippines and wider SE Asian market.


ACTI-Mag Asia Inc. is Calix Limited first venture into the growing Asian market. For more information:

The Website of the ASCENT Project has been launched.

06 June 2014


Calix is part of a 16-member consortium winner of € 7m grant in the EU ASCENT program “New generation high-efficiency CO2 capture processes”.


ASCENT, Advanced Solid Cycles with Efficient Novel Technologies, addresses the need for original ideas to reduce the energy penalty associated with capturing carbon dioxide during power generation, and create a sustainable market for low carbon emission power with low associated energy penalties.


ASCENT will provide a robust proof-of-concept of three related high temperature processes; each will lead to a step-change in efficiency of carbon removal in three types of pre-combustion capture, producing the hydrogen needed for highly efficient low-carbon power production.


You can register directly on the new ASCENT Website if you wish to download informative documents, participate actively to the discussion in the Forum of your interest and track our Project:

Calix awarded EU Ascent Grant to compliment its Endex CO2 Capture Demonstration Project.

18 October 2013


Calix has been awarded a €750 k grant over the next four years as part of a collaborative grant with 13 universities and companies, as well as the Australian CO2CRC, to study new CO2 sorbents for application in its Endex CO2 capture technology.


The grant comes on top of the UK Government’s DECC award of £5.8 m to develop the Endex technology as a demonstration project, which is progressing through Front-End Engineering Design. The grants reflect the growing interest in Calix’s Endex technology as potentially the most energy-efficient process to de-carbonise fuels available that is industry ready. Other highpotential applications of the technology in capturing CO2 and sulphides from natural gas, and in the production of urea, continue to be explored.

Calix technology and ocean liming - a possible response to runaway global warming

08 October 2013


A recent publication in Volume 60 of the "Energy" international journal, by P. Renforth, B.G. Jenkins, and T. Kruger, has highlighted Calix technology as a possible solution to runaway global warming…


Engineering Challenges of Ocean Liming



  • The addition of calcium oxide powder to the ocean could be used to sequester atmospheric CO2.
  • For every tonne of CO2 sequestered, between 1.4 and 1.7 tonnes of limestone would have to be processed.
  • The thermal and electrical requirements could be up to 5.6 and 1.2 GJ tCO2−1 respectively.
  • OL could cost approximately US$72–159 t−1 of CO2.



The relationship between the level of atmospheric CO2 (carbon dioxide) and the impacts of climate change is uncertain, but a safe concentration may be surpassed this century. Therefore, it is necessary to develop technologies that can accelerate CO2 removal from the atmosphere. This paper explores the engineering challenges of a technology that manipulates the carbonate system in seawater by the addition of calcium oxide powder (CaO; lime), resulting in a net sequestration of atmospheric CO2 into the ocean (ocean liming; OL). Every tonne of CO2 sequestered requires between 1.4 and 1.7 t of limestone to be crushed, calcined, and distributed. Approximately 1 t of CO2 would be created from this activity, of which >80% is a high purity gas (pCO2 > 98%) amenable to geological storage. It is estimated that the thermal and electrical energy requirements for OL would be 0.6–5.6 and 0.1–1.2 GJ tCO2−1 captured respectively. A preliminary economic assessment suggests that OL could cost approximately US$72–159 t−1 of CO2. The additional CO2 burden of OL makes it a poor alternative to point source mitigation. However, it may provide a means to mitigate some diffuse emissions and reduce atmospheric concentrations.
