Solenis earns EcoVadis Platinum, ranking in top 1% globally. Seven-year run of top-tier performance includes four Platinum ratings since 2020 Filed under Sustainability. July 15, 2026 Solenis, a leading global provider of water and hygiene solutions, has earned Platinum recognition from EcoVadis, placing the company in the top 1% of all companies assessed worldwide. The distinction underscores both the rigor of EcoVadis' methodology and the rarity of Platinum status, awarded to companies ranking in the top 1% of performance globally across environmental, labor and human rights, ethics and sustainable procurement criteria. With this recognition, Solenis extends a seven-year streak of top-tier sustainability performance, ranking in at least the top 5% globally every year since 2020 and achieving four Platinum ratings since 2022. "Sustained performance at this level doesn't happen by chance," said John Panichella, Chief Executive Officer, Solenis. "Earning EcoVadis Platinum again reflects the consistency of our approach and the accountability we've built into how we operate worldwide." "EcoVadis evaluates both the strength of management systems and measurable results," said Dr. Lotta Kanto Öqvist, Chief Sustainability Officer, Solenis. "Returning to Platinum reinforces that we are continuing to strengthen our programs, expand transparency and deliver measurable progress across our operations and value chain." EcoVadis assessments are based on internationally recognized sustainability standards, including the Global Reporting Initiative, United Nations Global Compact, and ISO 26000, and are conducted through a structured, evidence-based assessment and percentile ranking methodology.
Solenis, a global provider of water and hygiene solutions, has released its 2025 Sustainability Report, detailing progress driven by business growth and integration. The company invested $4.68 million in sustainable capital projects, improved workplace safety by 22% year-over-year, and achieved 96% participation in its culture survey. The report highlights $349 million in documented customer value delivered through its ValueAdvantage programme, up from $257 million previously. Additionally, 74% of revenue came from solutions supporting customer sustainability initiatives, whilst 91% of active innovation programmes focused on sustainability or circularity. Solenis completed integration of recent acquisitions and announced the acquisition of NCH Corporation, which closed in November 2025. The company also opened a new Global Research Center in Delaware to develop solutions for water stewardship and resource efficiency.
