With the DS8 True Biotic, Prodir sets a new standard for the use of sustainable materials. The entire housing (body, clip and push button) is made of bio-based plastic-free biopolymers (PHA), which are therefore biodegradable. Microorganisms can synthesize PHA through fermentation and break it down in salt and fresh water and soil - they have been doing so for millions of years in all natural environments. The synthesis and degradation of PHA follow nature's carbon cycle. Certified by TÜV Austria. The DS8 True Biotic combines maximum durability with top quality design and workmanship.
