Introducing Claire de Jacobi du Vallon

Claire joined Calix as a process engineer in January 2021. She started at Calix as the primary BATMn plant operator, working to complete trials and assist in the development of test plans. Claire was also involved with data processing and reporting of results from the BATMn plant to assist the Engineering Team with feasibility studies and design phases for various projects.

Now, Claire works as the R&D Plant Coordinator, where she is responsible for working with key stakeholders to identify and facilitate program and trial requirements in the BATMn plant. She is also heavily involved in ensuring safe operating procedures are maintained and utilised and the plant, and its works, comply with all Safety, Environmental and Quality requirements.

Prior to joining Calix, Claire graduated with a Bachelor of Chemical Engineering from RMIT University, where she spent her final year completing numerical studies to investigate flame speeds of alternative fuels

News Issue April 2022

Welcome to Issue Number 41 of the Calix Newsletter.

“In the recent quarter, Calix achieved a significant milestone with the LEILAC-2 Project for CO2 mitigation in the cement and lime industries, passing its Financial Investment Decision with the full support of the project consortium. This achievement was even more significant given the significant supply chain and war risks that have added considerable uncertainty, but is a testament to the resolve of the consortium to push on with the project, given the pressures and commitments to CO2 mitigation.

In this newsletter, we also explore the opportunity for the LEILAC technology in the lime industry, as well as the effort, and reasons, to develop electrification of the Calix technology. The Calix technology is being developed as a “future-proofing” option for industry. CO2 capture is a primary goal for cement and lime, but also the ability to use renewable energy including electricity and waste fuels or biomass is becoming a central value proposition as energy prices soar, and is a subject of renewed focus and development of the technology for application across many other industries.

In our water business, we look at some recent customer case studies in the US for sewer treatment, and in Asia for aquaculture. We look forward to the recession of COVID-constraints to re-ignite our growth in both these industries, given the considerable market opportunity.

In our biotech business, we achieved a significant milestone with the approval of BOOSTER-Mag – our safe, environmentally friendly crop protection product – by the Australia Pesticide and Veterinary Medicines Authority (APVMA). This represents over two years of independent assessment of safety and efficacy of our unique product and market entry planning for the Australian 22/23 season is underway. We are very encouraged by this progress and while applications such as crop protection take time, the same environmental themes driving investment in CO2 mitigation are also starting to focus on agriculture, where we have a unique product, uniquely positioned.

In this newsletter we also feature our first Communication on Progress (“COP” report) as members of the United Nations Global Compact, focussing on our efforts in Environment, Social and Governance improvement both externally, with our stakeholders and customers, and internally, with goals we are setting for ourselves as a company.

We also feature our new team members and also Doug Kelley – our US colleague leading the IER team – and his background, in our quarterly “meet the team” article. Despite a growing team, Calix remains very focussed on hiring the right people with not only excellent skills and competencies to grow our ambition, but also alignment with our corporate objectives. Both are equally important.

As always, we continue to very much appreciate the support of all our shareholders and stakeholders as we continue our journey and ambition, to help solve global challenges, using our unique technology and dedicated team.”

Introducing Doug Kelley

Dr. Kelley is a PhD Chemist with 29 years of research & development experience in water and wastewater treatment technologies.

Doug graduated from Iowa State University in 1990 with a Doctorate in Inorganic Chemistry. He worked with Nalco for 14 years in basic research and new product development.

He is also the co-inventor on numerous patents related to scale and corrosion control in boiler and cooling water environments.

As President of Inland Environmental Resources (IER), Doug has spearheaded the development of proprietary, safe, environmentally-friendly and cost-effective chemical products based on magnesium hydroxide.

Dr. Kelley is a member of the American Chemical Society, American Society of Heating, Refrigeration and Air-Conditioning Engineers and the Water Environment Federation.

“We greatly appreciate the opportunity we get everyday to work closely with our vendors to serve our customers’ needs, helping their business run as smoothly as possible and keeping their wastewater systems operating at peak performance.”

“IER offers more than 100 years of combined experience in the areas of municipal and industrial wastewater and process water treatment. IER shares Calix’s passion to provide their uniquely stable and reactive magnesium hydroxide products for further growth into their primary North American markets, and to expand the applications of these high-quality, environmentally-friendly technologies into new markets.”

Introducing Aqeel Mohaisen

Aqeel Mohaisen is our new CAD technician. Because he has a strong interest for anything related to sustainability, Aqeel saw an opportunity to use his practical skills to solve environmental problems by joining Calix.

Introducing Max Strokon

Max graduated from the University of Sydney with a Bachelor of Chemical and Biomolecular Engineering. His honours thesis focused on the effects of mechanical stress on 3D-printed plastics and how heat exposure affected the molecular structure printing filament.

Max’s early career began with boutique prototyping consultation and technical advice regarding CAD-CAM systems. Most recently he worked in the medical device industry as a design engineer, specialising in primary packaging for high value sterilised devices.

Max has joined Calix as a technical development support engineer with a view to leveraging his prototyping and production experience, to assist with ongoing engineering projects. “I care about implementing technology that is sustainable, to protect the environment of the planet we all share.”
