ASX Announcement: Calix announces chemical multinational company, Solvay, will join the LEILAC Project Consortium

· Calix’s LEILAC Project is a €21m, EU-funded pilot project to demonstrate Calix’s Direct CO2 Separation technology for the cement and lime industries
· Materials and specialty chemicals multinational Solvay ( has joined the LEILAC Project Consortium
· Solvay is one of the world’s largest producers of soda ash and sodium bicarbonate which are used in many applications or end-products. The “Solvay Process” uses amongst other feedstocks, limestone (for lime) and CO2 to produce soda ash.
· Solvay and Calix will explore the use of Calix’s patented Direct Separation technology, at the heart of the LEILAC Project, to help support Solvay’s objective to reduce its CO2 emissions.

Sydney, Australia | September 12, 2019 – Multi-award-winning Australian technology company Calix Limited (ASX: CXL, ‘Calix’ or ‘the Company’), is pleased to announce Solvay, an advanced materials and specialty chemicals multinational, has joined the LEILAC Project Consortium.

Phil Hodgson, Managing Director and CEO of Calix, said: “We are very pleased to have Solvay join the LEILAC Project Consortium as this further validates the interest and potential application of the technology to reducing CO2 emissions for large scale industrial manufacturing processes.”

Solvay Joins LEILAC Project Consortium

Solvay S.A. has joined the Project LEILAC Consortium and, subject to final approval by the European Commission on a change in the Project Grant Agreement to add Solvay to the Project, will contribute engineering expertise for the balance of the project. The funding for this resource will be paid for by Solvay and is not covered by the existing grant from the European Commission.

Solvay, founded in 1863, is an advanced materials and specialty chemicals company, committed to developing chemistry that addresses key societal challenges. Solvay innovates and partners with customers worldwide in many diverse end-markets. Its products are used in planes, cars, batteries, smart and medical devices, as well as in mineral and oil and gas extraction, enhancing efficiency and sustainability. Its lightweight materials promote cleaner mobility, its formulations optimise the use of resources, and its performance chemicals improve air and water quality (

The “Solvay Process” to produce soda ash uses, amongst other feedstocks, limestone (for lime) and CO2. One of the LEILAC Project objectives is to demonstrate Calix’s Direct Separation of CO2 from processing limestone to produce lime. Application of the Calix process to the Solvay Process is thus being investigated as part of the development of the technology, which would support Solvay’s objective to reduce its CO2 emissions.

The LEILAC Project is currently undergoing an engineering program to address the issues previously outlined in the commissioning and initial test phases, including burner modifications, control systems, and powder handling, before progressing to the next series of tests designed to test the technology to design capacity. In parallel, planning continues on the next scale-up of the technology – a demonstration-scale facility (20% to 25% of a full-scale cement plant, and equivalent to a large-scale lime plant).

Calix has noticed interest in CO2 capture from the cement and lime industries, and now more widely from other industrial players such as Solvay, is increasing.

In February 2018, The EU Council of Ministers approved the reform of the EU-ETS for phase 4 (from 2020) to steepen the pace of annual emissions cuts to 2.2%, as well as restricting further the surplus of free allowances. In response, CO2 allowances have had a sustained increase in price. This will no doubt impact European companies with exposure to CO2 emissions.

BBC Broadcast special “People fixing the world” features concrete, its CO2 footprint and the importance of the LEILAC Project

A recent BBC programme, “People Fixing the World” featured “The Concrete Cleaners” which highlighted cement, and its CO2 footprint. HeidelbergCement’s Director of Alternative Resources, Global Sustainability Jan Theulen was featured and discussed the LEILAC Project. The broadcast can be found here

HeidelbergCement is one of the world’s largest cement companies, with 139 cement plants globally with a capacity of 176 million tonnes.
