Uniquely Certified for Marine Protection: Our Biodegradability Guarantee

Inspired by a deep respect for the environment, particularly our precious marine ecosystems, Nuncas Marine products are meticulously crafted to deliver high performance while being fully biodegradable in saltwater. What sets Nuncas Marine apart is that our commitment to biodegradability is uniquely backed by an official certification.

This is proven by a certificate issued by Innovhub SSI in January 2025, following rigorous testing of ten key Nuncas Marine products according to OECD 306 standards. These tests confirmed a degradation trend identifying them as biodegradable samples in a marine environment and demonstrated no toxic or inhibitory effects on the testing environment's biota over approximately 40 days.
