The Corozo Buttons are one of the most sustainable buttons that I have found. Usually, buttons are made from wood, shell, plastic and mettle.
The Corozo or Tagua (it's indigenous name) nut comes from very large palm trees. They grow extensively in northwest South America, starting north of Peru, all throughout Ecuador and Colombia, and southern Panama.
These seeds are only ever gathered once they have fallen ensuring no harm ever comes to the Palm Trees.
The company supports the local community by generating one thousand full-time and part-time low-skill labour jobs in depressed and impoverished communities. These jobs help the communities to grow economically and prosper and, consequently, button production increases the quality of life for the residents. These community members are often seen doing jobs such as gather, prepare, dry, peel, cut, turn, grade and transport the seeds unless they have a higher degree of learning.
All dyes used in the processing of these buttons are certified to be nontoxic and biodegradable. Just because it's biodegradable doesn't mean it won't last you! At a microscopic level, corozo is composed of very tightly wound fibers. Therefore, articles made of corozo are naturally durable, with excellent scratch, heat, impact and weather resistance. Clothing with corozo buttons can be machine washed, steamed, dry cleaned and even ironed with no harmful effects.
