A purpose-led company

At Calix we believe it's not so much about what we do,
it’s why we do it.

Read our Company Profile

We’re driven to use our unique skills to repair, preserve and prevent future harm to our planet.

Because there is only one Earth. Mars is for quitters!

Contributing to the United Nations Sustainable Development Goals

Driven by our purpose of solving global challenges, we focus on four overlapping pillars of sustainability: CLIMATE | ENERGY | FOOD | WATER

Calix touches all 17 SDGs through innovation, development and partnership initiatives, day-to-day operations, and social investment opportunities, but have identified 11 goals that identify where we believe we can make an impactful and meaningful contribution. We work with key partners, communities, and industry groups to maximize positive outcomes and continually deepen our understanding of sustainable development.


Reducing CO2 emissions from the cement industry

Calix’s technologies are being developed and adopted to reduce CO2 emissions in the cement, lime, and magnesia industries. Calix is the leader of the LEILAC (Low Emissions Intensity Lime and Cement) Project. This European Union Horizon 2020 research and innovation project will help Europe’s cement and lime industries reduce their CO2 emissions dramatically, without significant energy or capital penalty. The LEILAC project is based on Calix’s direct separation technology that enables pure CO2 to be captured as it is released from limestone. This process requires no additional chemicals, nor any changes to conventional processes for cement, as it simply replaces the pre-heater tower in a cement plant, or lime kiln in a lime plant.


Making crop protection safer

In agriculture, there is an increasing need for 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 is developing  BOOSTER-Mag to make crop protection safer. This non-toxic, broad spectrum, effective anti-fungal, anti-pest fertiliser overcomes many of the problems around both pesticides and fungicides – on average at a far lower cost.

Feeding a growing human population

Aquaculture is seen as a viable way to meet growing demand for animal products globally, with more efficient feed use than cattle or pig farming. As developing  countries begin to adopt more sophisticated farming techniques, downstream environmental effects will become more pronounced. Calix’s AQUA-Cal+ is an innovative, safe and earth-friendly solution for the improvement of pond health and the optimisation of shrimp and prawn aquaculture production. The high reactivity and surface area of AQUA-Cal+ gives the farmer greater control in both pond preparation and during the grow out. Some of the many benefits of using AQUA-Cal+ in aquaculture ponds include stabilisation of iron, and the control of alkalinity, ammonia and nitrate.


Improving the sustainability of water management

Water is an increasingly fragile resource that needs to be protected. There is a global imperative for every nation to contribute to smarter, more effective water and wastewater treatment. This means operators in industries that rely heavily on water, such as agriculture and food production, need to be proactive in their approach to water management. With rapid urbanisation, development and increasing environmental pressure on industrial emissions, it is time we rethink the way we treat and reuse wastewater, without compromising our health, our land and waterways. Calix’s ACTI-Mag magnesium hydroxide (Mg(OH)2) is an earth-friendly alternative to caustic soda and other solvents used for alkalinity adjustment, odour control, sewer infrastructure protection and wastewater treatment performance.

Calix’s AQUA-Cal+ is being developed as part of treatment regime to restore freshwater systems suffering from a lack of oxygen, phosphate and nitrogen overload leading to blue-green algae outbreaks.


Creating renewable energy

Energy use and expenditure can be offset using biogas, which can be achieved by capturing methane from wastewater. The effluent load in untreated wastewater includes carbon, which is converted into methane in wastewater biotreaters and can be captured and burned to provide power. It is therefore important to find ways to improve the efficiency of methane production from wastewater.

Calix’s ACTI-Mag solution has been shown to improve energy efficiency through improved biogas generation as well as more efficient wastewater treatment. Industrial wastewater producers have been able to cut energy bills and even supply energy back to the grid.

Making better batteries

The growing 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 is 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 is  developing high performance, low-cost, fast charge-discharge, lithium-ion hybrid batteries based
on nano-active electrode materials.

At Calix, our vision is to become a leading global innovator of industrial solutions for the environment. Driven by our purpose of solving global challenges, we focus on four overlapping pillars of sustainability.
