Water is under pressure. Climate change, aging infrastructure, and rising demand are reshaping how we manage this vital resource. Yet public perception often lags behind expert data – creating a gap that hinders action. The Kemira Water Index 2025 bridges that gap, combining expert insights with global sentiment to reveal how resilient our water systems really are. Explore the Index and see where action is needed most.

Big cities like Paris can get extremely hot during summer. When concrete structures heat up, summer in the city can get awfully exhausting, and citizens are craving for a swim. After 102 years, Paris has re-opened the Seine river for public swimming. Award-winning technology is a key enabler.

The wastewater treatment plant in the city of Hamburg opted for a renewable, biomass-balanced polymer, as an additional step toward smore sustainable operations.

Kemira collaborates on a project led by Professor Mathieu Lapointe to identify sustainable methods for removing water contaminants that pose significant health risks. The research involves several industry experts and emphasizes the importance of academia-industry partnerships for developing practical, large-scale solutions to protect public health and the environment.

The wastewater from DAKA´s production process varies with challenging compositions. The effluent is released to a highly sensitive recreational area. Automated monitoring and dosing technology is helping to achieve a consistent quality in compliance with regulatory requirements.

Cooling off in a local lake or river is one of the joys of summer – as long as wastewater discharged there has been properly cleaned. Berliner Wasserbetriebe implemented a safe, effective and sustainable solutions at its biggest treatment plant, to achieve compliance with EU bathing water directive.

As an additional measure to make operations more sustainable, the Paljasaare wastewater treatment plant in Estonia´s capital city Tallinn decided to switch from conventional fossil-based Polymers to a renewable, biomass-balanced alternative product.

Water scarcity and reuse, stormwater management, regulatory compliance and pressure to cut costs and find sustainable solutions, are key drivers impacting wastewater disinfection. This webinar discusses safe and sustainable disinfection using performic acid as an emerging method with low capital investment and energy needs.

In preparation for the Paris Olympic and Paralympic swimming events in the river La Seine in 2024, the Greater Paris Sanitation Authority trusted Kemira with it´s performic acid solution, KemConnect® DEX, for their project of disinfecting treated wastewater before discharging.

The answer is yes. Water-intensive industries can now transform their sustainability performance, with one simple switch: from fossil-based polymers to renewable biomass-balanced chemistries from Kemira.
