Investment Overview
Kemira is investing nearly €20 million to expand its production capabilities in Tarragona, Spain. This investment will facilitate the construction of a new production line for Aluminium Chloro Hydrate (ACH), a coagulant used in drinking water treatment.
Production and Technology
The new facility will utilize proven technology already in use at Kemira’s sites in the United States and Poland. ACH offers a higher aluminum concentration compared to conventional products, enhancing treatment efficiency and reducing logistics-related CO₂ emissions.
Timeline and Environmental Impact
The new production line is anticipated to be operational by early 2028, following the completion of permitting processes. The project aims to have minimal environmental impact, supported by renewable energy use and mitigation measures for emissions from natural gas usage.
Market Expansion
This expansion strengthens Kemira’s position in the European and African markets, addressing the growing demand for advanced water treatment solutions, particularly in urban areas facing climate-related challenges.
