Investments in water technology companies

  • Why invest in companies involved in water treatment?

  • Water is a valuable asset. There is now a lack of clean water in many parts of the world. Our water needs will continue to increase sharply over the next few decades due to population and economic growth. In addition, many countries are facing the problem of increased water contamination.

    By investing in companies in the water industry, we hope to make a contribution to water being used efficiently and sustainably as a resource. SKion therefore invests in companies involved in, for example, waste water treatment, resource recovery, closed water cycles and increased energy efficiency.
