Key Sustainability Trends 



With global climate, energy, and sustainability challenges set to intensify, Calix has identified some of the key trends that have emerged in the last decade and why they are likely to accelerate, and dominate, in the next decade. 

 Calix's LEILAC facility in Belgium

Calix's LEILAC facility in Belgium nearing completion, December 2018.

LEILAC will demonstrate Calix's CO2 capture technology for lime and cement.

Reducing CO2 Emissions


Carbon dioxide (CO2) emissions are largely accepted to contribute to climate change, with governments around the world setting targets to reduce these emissions as well as setting up emissions trading schemes whereby companies must pay for the CO2 they emit under ‘cap and trade’ type systems. From 2021, the European Commission will be reducing their CO2 cap by 2.2 per cent each year. The EU Emissions Trading Scheme (ETS) has consequently seen the price of CO2 rise from less than three euros per tonne in 2013 to 25 euros per tonne in August 2018. That price has backed off slightly but the over-arching trend represents considerable pressure on companies to reduce their emissions. While the US and China don’t have an ETS / ‘cap and trade’ system, China is closing down old cement plants with high emissions and building new plants that will create fewer emissions.

Calix is helping reduce cement industry emissions. Calix is a leader in the Low Emissions Intensity Lime and Cement (LEILAC) project, due to be completed in 2020. The project is investigating and proving the efficacy of its carbon capture.


Creating Renewable Energy




While energy prices are high in Australia, they pale in comparison to the prices in some parts of Asia. This can be offset by using biogas for energy, which can be achieved by capturing more methane from agricultural activities. The effluent load in untreated wastewater
includes carbon, which can be converted into methane, and burned to provide power. The agricultural sector is therefore, looking for ways to improve the efficiency of methane production.

Calix ACTI-Mag is a magnesium hydroxide formula that helps maintain optimum bacterial growth conditions for the conversion of organic matter into biogas for energy. It delivers up to 20 per cent more biogas while lowering chemical consumption and being safer and easier to use.








Making Crop Protection Safer



In Europe, fungicides and pesticides need to be re-registered every 10 years to ensure they comply with stringent safety standards. Many of the products in use currently are unlikely to achieve re-registration in
the next few years, creating demand for safer alternatives. The cost to develop a new crop protection product averages US$250 million and 10 years, but farmers need safe, affordable crop protection products now. There is therefore increased interest in products that are safer and better for the environment, such as mineral-based sprays that improve productivity and boost resistance to pests and diseases.


Calix has completed its third year of trials of BOOSTER-Mag on grapes in the Champagne region of France, as well as a successful trial on onion crops in the Netherlands. This follows years of successful trials in Australia. BOOSTER-Mag is an easy-to-apply and safe foliar spray. Treatment coincides with improved crop yield and reduced pest and disease pressure - A fertiliser and crop protection benefit delivering improved vitality and yield.




Feeding the Growing Human Population




As developing countries begin to adopt more sophisticated farming techniques, the downstream effects will become more pronounced. This is important across all forms of food production and, particularly, aquaculture. Aquaculture can be an environmentally negative activity where uneaten food and waste material from the animals being farmed turns into sludge. To make this industry more sustainable, aquaculture operators need to find a way to efficiently break down these polluting sludges, as well as increase yields through lower disease and higher feed / product efficiencies.


Calix AQUA-Cal+ is a water conditioner that safety addresses disease and pollution, delivering improved feed performance and yield. It has already begun to transform prawn and shrimp farming, as well as fin fish farming. As well as improving water conditions, it reduces stress on the animals and leads to increased harvest weight and survival rates, while reducing energy costs and protecting the environment.




Protecting Ageing Infrastructure


Many of the developed world’s sewers are reaching the end of their 50 - 100 year lifespan, damaged and corroded by decades of use and increasing biological loads due to changes in food and detergents. Replacing this infrastructure is prohibitively expensive and, in some cases, impossible. Rehabilitation and protection are, therefore, very attractive alternatives to massive replacement infrastructure spending.

Calix has conducted numerous highly successful applications of its unique PROTECTA-Mag spray, which forms a protective layer over the concrete sewer assets, protecting them from corrosion. PROTECTA-Mag
raises the pH in sewers and reduces odours as well as corrosion. As more councils begin to appreciate the need to invest in asset protection to prolong their lifespan, Calix is seeing ongoing interest in this technology as an alternative to previous ‘run to fail’ approaches.



Making Better Batteries


The increased interest in electric vehicles and the need for efficient, cheap, and high-capacity electricity storage means there is a global demand for better batteries. There will be a need to create advanced
materials for lithium ion batteries that deliver superior performance at a fraction of the cost, with improved ease-of-recycling.


Calix recently received an Australian Advanced Manufacturing Growth Fund award to produce advanced materials for lithium ion batteries. With cheap, agricultural-grade manganese carbonate, Calix, using its CFC technology, created various controlled oxidation states of highly-porous manganese oxide, which is a common lithium battery material. This technology could be a gamechanger in terms of providing a cheap sustainable advanced material for li-ion batteries.
