We cherish our equipment like a treasure and can't get enough of the chic colours and shapes of our carabiners, exes & co. However, our addiction to equipment also has its price.
Toxic chemicals are used to anodise our hardware. The waste water produced after the dyeing process is toxic and, if not disposed of properly, extremely harmful to humans and the environment. In fact, anodising is primarily used to colour our hardware. It has no influence on their strength. Okay - it also increases their corrosion resistance, but with normal use and proper storage, this is negligible.
