Key Highlights

  • Zeotech has signed a non-binding Memorandum of Understanding with Sunstate Cement Limited, a Queensland cement manufacturer jointly owned by Adbri and Boral.
  • Zeotech will supply agreed quantities of AusPozz metakaolin with technical support, while the parties exchange technical information and test results from concrete trials.
  • The MOU has a 12-month term and either party can end it by giving 30 days' written notice.
  • Sunstate Cement has capacity to produce more than 1.5 million tonnes of cement a year and has supplied customers in Queensland and northern New South Wales for over 40 years.

Zeotech Limited (ASX:ZEO) has signed a non-binding Memorandum of Understanding (MOU) with Sunstate Cement Limited to collaborate on concrete trials and demonstration projects using AusPozz™, the company's high-reactivity metakaolin. Sunstate Cement is a Queensland-based cement manufacturer and supplier jointly owned by Adelaide Brighton Cement Ltd (Adbri) and Boral Cement Limited (Boral). The agreement, announced on 21 October 2026, runs for 12 months and sets out how the parties will share material, technical support and test results.

What the MOU Asks of Zeotech and Sunstate Cement

The MOU establishes a framework for Zeotech, Sunstate Cement and its shareholders to work towards four stated objectives. The first is that Zeotech provides agreed quantities of AusPozz for concrete trials and demonstrations, together with technical support and guidance for the Sunstate Cement project team. The second is an exchange of technical information and test results to support the development and commercialisation of AusPozz in construction, subject to the intellectual property and confidentiality provisions of the MOU. The third is to advance the use of high-reactivity metakaolin in low-carbon concrete products, and the fourth is to support Zeotech's development of AusPozz for commercialisation in construction.

The parties will identify suitable concrete trial programs and demonstration projects. Results generated through the collaboration will be exchanged and assessed to support the commercialisation of AusPozz and to identify potential future commercial engagement. The MOU is non-binding and has a 12-month term, and either party may end it by giving 30 days' written notice.

Zeotech said the collaboration builds on its broader AusPozz commercialisation strategy and offers a chance to evaluate the product with an established cement manufacturer and supplier of supplementary cementitious materials operating in the Queensland and northern New South Wales construction markets.

AusPozz Metakaolin and Its Role as a Cement Replacement

Zeotech describes AusPozz as its proprietary high-reactivity metakaolin, manufactured from the company's wholly owned, high-purity Toondoon kaolin resource in Queensland. It is classed as a supplementary cementitious material (SCM), a material designed to replace a proportion of Portland cement in concrete. Zeotech says this reduces the embodied carbon of concrete while enhancing strength, durability and long-term performance. Zeotech says AusPozz was developed to support the transition to lower-carbon construction materials and is aimed at a broad range of concrete and infrastructure applications.

The company reports that independent testing has demonstrated cement replacement rates of up to 40% in optimised concrete mixes, with improved compressive strength, reduced shrinkage, enhanced durability and mitigation of Alkali-Silica Reaction (ASR). The trials planned under the MOU are expected to help validate AusPozz as an SCM that can reduce the total binder and embodied carbon of concrete, and to demonstrate its compatibility with modern concrete production systems.

Sunstate Cement's Plant, Capacity and Executive Comments

Sunstate Cement is Australian-owned and Queensland-based, with more than 40 years of experience supplying commercial customers throughout Queensland and northern New South Wales. It has the capacity to produce more than 1.5 million tonnes of cement per year and a long history of supplying Queensland infrastructure projects. Its plant is at the Port of Brisbane, where operations are supported by a certified Quality Management System and a NATA-accredited laboratory facility that undertakes daily product testing.

Sunstate Cement Managing Director Peter Edwards said the company has a long history of supplying cementitious products to Queensland and northern New South Wales, and that the collaboration provides a chance to evaluate AusPozz through concrete trials and to understand its performance and potential use as an SCM in lower-carbon concrete.

Zeotech Chief Executive Officer James Marsh said the MOU allows Zeotech to progress the commercialisation of AusPozz with an established Queensland cement manufacturer and supplier and its shareholders, and that Sunstate Cement's product portfolio and technical capability provide a platform for practical trials and demonstrations. He added that the collaboration is expected to generate further technical data and support the pathway towards broader market adoption of high-reactivity metakaolin as a lower-carbon SCM.

Taking Stock of the Sunstate Cement MOU

Zeotech Limited (ASX:ZEO) has agreed a non-binding, 12-month MOU with Sunstate Cement Limited under which it will supply agreed quantities of AusPozz and technical support for concrete trials and demonstrations, while the parties exchange technical information and test results. The parties will next identify suitable trial programs and demonstration projects, and the results will be assessed to support the commercialisation of AusPozz. Either party can end the MOU on 30 days' written notice.
