Welcome to Issue 31 of the Calix Newsletter.


Dr Phil Hodgson - Calix Managing Director & CEO

A lot has happened since our last newsletter in February, 2019.

Our LEILAC (Low Emissions Intensity Lime and Cement) Project in Belgium was officially opened at completion of construction by Cristoph Streicher, General Manager Benelux and Peter Lukas, Global Director of Environmental Sustainability for Heidelberg Cement on May 7 – having been completed on time and on budget. We wait with anticipation while our first “fingerprinting runs” are conducted to prove the process technically over the next few weeks.

Our ACTI-Mag businesses in waste water continues to find new applications, with feature in this newsletter on chromium treatment from tannery waste. Also, our AQUA-Cal business continues to grow very quickly, in China, with twelve containers shipped so far this year compared to one last year.

Our BOOSTER-Mag product continues its commercialisation, with a fourth Material Transfer Agreement signed with a global major crop protection company.

You may have noticed a change in the design of this newsletter – we have also undertaken a brand refresh and will be rolling out our new marketing materials and a fresh website over the course of the next few months.

We feature this brand refresh and its underlying reasons and messages in this newsletter.

We at Calix hope you enjoy reading about our progress in this newsletter and thank the continued support of our shareholders and stakeholders.

Announcing Calix's refreshed brand identity

Calix is pleased to announce the launch of our refreshed corporate brand identity. The new brand reflects a process of consultation with our staff and some external stakeholders, where we asked what people think we do, how we do it, and perhaps most importantly, why we do it.

"What we do" was broadly understood and agreed: “solving global challenges” has been the basis of our passion and our business for over a decade, in our quest to become a leading global innovator of industrial solutions for the environment.

"How we do it" again brought to the fore our staff’s broad agreement on our values of inclusiveness, continuous improvement for ourselves and our customers, and creating a positive impact through a down-to-earth attitude, care, integrity, and ingeniousness.

"Why we do it" was more tricky! While all our staff brought different perspectives to bear on why they do what they do, we initially found it difficult to wrap it into a common, pithy theme that resonated with all. After a suggestion that Elon Musks’ “Space ” had their “why” nailed – a picture of Mars – a theme emerged that quickly brought together the different perspectives, as well as reflect Calix’s personality – a little bit irreverent and fun at the surface, but very serious underneath. Because there’s only one Earth.

Mars is for quitters.™

The refreshed brand coincides with the upcoming launch of a new global website, which will enable us to tell our story and share the exciting things that are happening at Calix, through a variety of videos, technical content, and customer stories.

As we continue to pursue our purpose to make a great business that solves global challenges, we at Calix want to thank you all for your continued support.



Reducing CO2 Emissions

Project LEILAC has successfully commenced the commissioning process on time and budget.Key Milestones

Project LEILAC has successfully commenced the commissioning process on time and budget.


The commissioning activities over April has involved successful test firing the furnace burners, the testing of each process line, a furnace refractory dry-out, cold feed conveying, and extraction system testing.

On the 7th of May 2019, the LEILAC consortium partners and External Advisory Board met to celebrate the finish of construction with a ribbon cutting event at the LEILAC pilot plant. Supported by the European Union’s Horizon 2020 programme and extensive industrial backing, this event was a significant moment in the development of Calix’s Direct Separation technology, and the culmination of many years of hard work by all of the project partners.

The critical next steps for Project LEILAC involve “fingerprinting” the operation of the plant over May and June, including initial runs on lime and cement meal. These initial runs will significantly de-risk the technology and conclusively demonstrate its technical principles. The longer-term runs over the remainder of 2019 and 2020 will focus on extending the operational limits of the technology, as well as long-term studies on issues such as mechanical limits and fouling and corrosion, in preparation for scale-up designs for cement applications.

Calix is also pleased to announce that a new €1.5m working capital facility has been agreed with the Efic in support of Project LEILAC, which will support the project financing through to the end of February 2020.

Testing is now set to commence and start to validate the performance of the pilot, and a significant step in enabling Direct Separation to become one of the principal methods of capturing the carbon emissions from the lime and cement industries.



Protecting Ageing InfrstructureExtending the life of sewer assets.

Much of the infrastructure around Australia is starting to degrade, with some reports suggesting that up to $30 billion of community assets are in poor condition and require significant renewal.

This presents challenges as Australia’s population continues to rise and citizen health and safety depends on the ongoing availability and reliability of this infrastructure. Leaking pipes, unpleasant odours, and deteriorating structural integrity can all present significant risks, including immediate danger to people. It’s essential to find a solution to this problem of ageing infrastructure, and fast.

In many cases, assets have been managed in a run-to-failure model that results in faster deterioration, leading to higher replacement and emergency response costs. This can potentially be overcome with rehabilitation and regular maintenance of existing assets.

One of the biggest challenges in sewer networks is the corrosion that occurs to both metallic and non-metallic pipes. To prolong the life of the pipes, in some cases epoxy lining has been applied, ostensibly protecting against corrosion. However, in practice, epoxy linings are problematic and often fail to deliver results. This leads to further costs for councils who then need to rectify the failed epoxy lining.

With an emphasis on creating a sustainable future for existing infrastructure, there is a clear requirement for a cost-effective, reliable, and innovative solution to this longstanding problem.

Calix has developed PROTECTA-Mag, which is a magnesium hydroxide liquid (MHL) coating that prevents corrosion by raising surface pH. The patented biostatic formula neutralises acids that cause corrosion.

Unlike epoxy coatings, PROTECTA-Mag doesn’t require flow diversion or manual entry to be applied, and it’s around five times cheaper over the lifecycle of the asset. It’s completely safe to handle, non-hazardous to humans and the environment, and non-toxic to marine and plant life.

When repairs are required, Calix can re-grout the structure with calcium aluminate cement (CAC), which is a high-strength, highly corrosion-resistant repair mortar. Combining CAC and PROTECTA-Mag results in significantly rehabilitated assets that can continue to operate successfully for decades to come.


In fact, Calix offers a 20-year guarantee, providing peace of mind that assets will be protected long into the future. This, combined with Calix’s renowned reliability, quality, and engineering, means the solution will be tailored to the customer’s needs, delivering the best possible outcome.


ACTI-Mag Customer Story - Chromium Precipitation at a Tannery Plant

ACTI-Mag Customer Story

Chromium precipitation at a tannery plant.

The use of Magnesium Oxide (MgO) anti-acid agents in the leather tanning process is a worldwide industry practice. MgO is a simple chemical, but a complex material. Different types of processing, sources of production, and end-use requirements result in MgO products with very different physical characteristics, although chemically very similar.

A large Australian tannery plant was finding it difficult to mix and react MgO with water (“hydration”) and the process was very labour intensive. After discussions with Calix, they replaced its MgO hydration plant with a bulk storage plant to use Calix ACTI-Mag.

Produced by Calix’s patented Calix Flash Calcination (CFC) process, ACTI-Mag is a highly reactive, concentrated and stabilised suspension of magnesium hydroxide. Its particles have a very high surface area, which makes it more effective in “nucleating Chromium precipitation” – in effect forcing the chromium out of the waste water stream.

As such, ACTI-Mag is also applicable to the precipitation of a range of metals in waste streams - not just chromium. Calix's development efforts continue with this product, with a focus on improving its range of applications.

Calix ACTI-Mag is also safe to handle, non-toxic, and non-hazardous to humans and the environment.



More milestones for Calix’s safe, sustainable crop protection product BOOSTER-Mag.

Another milestone for Calix’s safe, sustainable crop protection product BOOSTER-Mag.

BOOSTER-Mag is a safe, low cost, environmentally sustainable and easy-to-apply foliar spray that can improve productivity and natural resistance to pests and diseases. We are pleased to have recently executed a fourth Material Transfer Agreement (MTA) for BOOSTER-Mag with another multinational crop protection company.

The MTAs represent a considerable investment of time and money by the counter-parties, following independent assessments of efficacy testing of BOOSTER-Mag over the past three years. Counter-party trials are currently in progress, which typically run for a minimum of two seasons, on specific crop, disease, and geographic region.

It is anticipated that Commercial licence arrangements for sales and marketing by crop, disease, and geographic region of BOOSTER-Mag will follow successful trials.

Calix continues to build the BOOSTER-Mag efficacy dossier necessary to achieve registration as a plant protection product in Australia.

A series of field tomato trials were completed over the 18/19 Australian summer to further quantify the effect of BOOSTER-Mag treatment on crop health and productivity.

The results show that relative to untreated controls, BOOSTER-Mag treatment coincided with statistically significant suppression for a range of damaging pests:

  • Helicoverpa spp. (cotton bollworm): Victorian and Queensland trials yielded consistent and positive data with treatment in both trials reducing fruit damage at harvest by between 60 to 77%.
  • Aleyrodidae (white Fly): Victorian trials indicate BOOSTER-Mag treatment coincided with a 65% reduction in pest pressure.
  • Tetranychus urticae (two spotted mite). Queensland trials indicate BOOSTER-Mag treatment suppressed motiles (adults & nymphs) to greater extent than the grower standard chemical treatment.
