As we reflect on World Oceans Day and its significance, it remains crucial to delve into the concept of marine biodegradability. This term refers to a material's inherent ability to decompose and disintegrate within marine environments through intricate biological processes. Bemberg™ undergoes a transformative journey within these ecosystems, gradually transitioning into simpler and non-toxic components, minimizing its environmental impact, and aligning with our sustainable values

  • The temperature of the sea was 30ºC, oxygen and nutrient salt were present when the measurements and images were taken.
  • The sewing thread and interlining cloth are made of synthetic fibers.

The journey towards obtaining the "OK biodegradable MARINE" certification for Bemberg™ began with Asahi Kasei's R&D Laboratory for Applied Product and the Italian certification organization INNOVHUB-SSI, which previously verified its biodegradability in soil. Building upon these findings, the recent certification confirms Bemberg™ as a biodegradable filament yarn that demonstrates biodegradability in landfills and marine environments.

Bemberg™ stands out as a remarkable material for a variety of reasons. It is derived from 100% cotton linter, a by-product of cottonseed oil manufacturing. The production process employs a unique closed-loop system, minimizing waste and conserving valuable resources. Asahi Kasei's commitment to sustainability is evident through the use of renewable energy in manufacturing Bemberg™. Furthermore, the biodegradability of Bemberg™ enhances its sustainability credentials.

The acquisition of the "OK biodegradable MARINE" certification for Bemberg™ continuous filament is a significant step forward in addressing the issue of marine microplastics. Bemberg™ can now be considered a potential help to reducing the harmful impact of microplastics on our oceans and marine life.
