For the plastic parts we use mostly use polylactide (PLA) which is a biodegradable and bioactive thermoplastic polyester derived from renewable resources, such as corn starch (in the United States and Canada), cassava roots, chips or starch (mostly in Asia), or sugarcane (in the rest of the world). It is also food safe.

For our metal parts we use either stainless steel or anodized aluminium.
