Ringe & Kuhlmann’s natural colorings are based on the use of sustainable raw materials. In addition, Ringe+Kuhlmann nature-identical colorings are produced in compliance with stringent environmental standards. For example, Ringe+Kuhlmann was one of the first companies in the city of Hamburg to use solar power, and solar panels installed in 1997 have already made it possible to feed more than 500,000 kWh back into the local power grid.
