Why Notpla Makes Kelpi Bones So Unique.

At Marine Kind, Kelpi Bones were always intended to be more than “better plastic”. The goal was to remove plastic altogether, which is why Marine Kind chose Notpla Rigid, a next-generation material made from seaweed and other natural ingredients, as the core of every Kelpi Bone.

Notpla is not just another bioplastic. It is a seaweed-based material that is naturally biodegradable and home-compostable, breaking down like fruit peel rather than lingering as microplastics. For Kelpi Bones, that means a chew toy that stands up to real-world play, then returns harmlessly to nature if it is lost in the garden, left at the beach or eventually worn out.

From a performance point of view, Notpla Rigid gives Kelpi Bones their distinctive feel: firm and durable enough to satisfy strong chewers, yet created entirely from natural inputs instead of PVC, phthalates or conventional plastics. This innovation has already been recognised with design and sustainability awards, including a Pentaward for the world’s first seaweed-based dog toy, showing that nature can perform just as well as plastic in a demanding environment like pet play.

From an environmental perspective, seaweed is one of the planet’s most exciting renewable resources. It grows quickly, needs no freshwater, fertiliser or land, and helps absorb carbon while making surrounding waters less acidic. By building Kelpi Bones from Notpla’s seaweed technology, Marine Kind supports a material future where dog toys no longer depend on fossil fuels, and where every fetch, tug and chew is part of a more regenerative system for oceans.

When you choose a Kelpi Bone from Marine Kind, you are not just choosing a safer, natural chew for your dog – you are backing a new class of seaweed-powered materials that show the future of pet products does not have to be plastic.
