Runoff from architectural solutions

In some European countries it has been suspected that corrosion-induced copper runoff from roofs and facades would cause harm for the environment. In the copper Voluntary Risk Assessment it has been calculated that only one percent of all diffuse emissions from copper's uses originate from architectural products.

Copper runoff induced by corrosion has been studied at the Royal Institute of Technology, Division of Corrosion Science in Stockholm, myriad of scientific articles have been published and presented at conferences. In addition a predictive model has been generated based on physicallyexplainable parameters, which allows modelling of the amount of copper that will be released. Research studies at KTH clearly illustrate that in reality the amount of copper runoff is very small, and when it gets in contact with soil or surrounding constructions of e.g. concrete, it immobilizes quickly to poorly soluble compounds. Copper use in architecture is not risking the environment.
