Algae Bioplastic PHA

🌿 Botanical origin Marine biodegradable
Supplied by Notpla Ltd
Food-contact safe EU approved AI-verified EUDR compliant

Polyhydroxyalkanoate (PHA) bioplastic produced through microbial fermentation using Atlantic seaweed (Ascophyllum nodosum) as the carbon substrate. Fully marine biodegradable, food-contact certified, and carbon-negative at the farm gate. Ideal for flexible packaging, coatings, and single-use food service applications.
