Kerakoll, a Benefit Company B Corp operating internationally in the construction sector, and Steda Holding have announced the completion of a strategic partnership agreement that involves the acquisition by Kerakoll of 60% of Caltra Nederland, a subsidiary of Steda.
Caltra Nederland is a Dutch company specialising in the development, production and sale of supplementary cementitious materials, SCMs, and low-carbon clinker, founded in 1984 by Ludo van Nes.
Caltra currently operates three production plants, with a fourth plant under construction also in the Netherlands, which is expected to be activated by the third quarter of 2025. The aim of the transaction is to combine skills and resources to develop alternative binders with low carbon emissions.
The decarbonisation of construction – with the cement industry responsible for about 7% of total greenhouse gas emissions – is one of the most important future challenges to achieve zero emissions. The use of additives, alternative materials and circular economy solutions, are some of the most promising solutions to reconvert the industry’s business models.
“The acquisition of a majority shareholding in Caltra marks a further step forward in the innovation and sustainability process embarked on by Kerakoll,” said Fabio Sghedoni, vice president of Kerakoll Group.
“With this strategic operation,” said Marco Zini, group CEO of Kerakoll, “our group secures an important international presence, in the heart of Europe, in terms of know-how on components that will be crucial for the development of alternative cements, such as SCMs and low-carbon clinkers.”
