Australia: Zeolite, kaolin and metakaolin producer Zeotech has appointed James Marsh as its new CEO, effective from 9 September 2024. Current CEO Scott Burkhart will then transition to chief operating officer. The appointment is intended to support Zeotech’s entry into large-scale production of high reactivity metakaolin for use in cement and concrete.

Marsh is a director of Australian Kaolin. He previously worked as executive director sales and marketing at Andromeda Metals, after holding managerial roles at multiple minerals companies. He has a bachelor’s degree in Chemistry and Physics from the University of the West of England, UK.

Managing Director Peter Zardo said "James' technical experience in the industrial mineral and cement industries, especially metakaolin, will be pivotal in accelerating Zeotech's goal of becoming a significant supplier of premium supplementary cementitious materials. Queensland-based leadership is critical to achieving the Company's objectives as we ramp up work programmes and industry engagement, and James will play an essential hands-on role in executing Zeotech's strategy."

James Marsh said "I'm excited to join Zeotech at a crucial stage of the company's strategy, where I can utilise my experience and connections to make it a significant player in decarbonising the construction industry."

Australia: First Graphene has partnered with Suvo Strategic Minerals to develop graphene-enhanced metakaolin for use in cement and concrete production. Metakaolin is a pozzolanic material derived from kaolinite clay. The partners believe that the technology has commercial potential to improve concrete performance and reduce CO₂ emissions.

Portugal: Researchers at the Department of Materials Engineering and Ceramics at the University of Aveiro have developed a so-called ‘eco-cement’ that uses waste cellulose and clay. The cement type uses waste from the pulp industry such as ash and lime grains. This makes up 70% of its composition with the remaining 30% being metakaolin clay. The cement can be manufactured at room temperature reducing its energy consumption massively compared to Ordinary Portland Cement. The research team includes Manfredi Saeli, Rui Novais, Paula Seabra and João Labrincha.

France: Hoffmann Green Cement Technologies’ pilot plant at Bournezeau, Vendée is set to start commercial production of low-carbon cement products in January 2019. Construction of the 50,000t/yr unit is due to be completed in October 2018 with its inauguration scheduled for late November 2018, according to Batiactu. The plant will employ 10 workers initially and this will rise to 15 – 20 as production ramps up.

The producer intends to make cement products using metakaolin and blast-furnace slag. If the pilot plant is a success it then intends to raise funds to build a 0.5Mt/yr plant.
