New materials for a plastic-free world

Our natural materials begin with design research and years of experimentation in our labs. By combining our natural polymer know-how with hands-on product design, we develop seaweed-based replacements for single-use plastic.

Searo® Materials are designed to slot into existing processes, so partners can move away from plastic and bioplastic without reinventing how they work. We understand the challenge of doing this at scale, and we collaborate with industry to take materials from the lab into the world.

Our Materials

Discover the properties

We have developed proprietary formulations and process that enable natural seaweed polymers to be converted into materials that look and feel like plastic without the need for harmful chemical... modification. This means that Searo® Materials are compatible with nature and cause no harm wherever they end up. We design materials that disintegrate, dissolve and can even be digested. Our goal is to make technology that accords with nature’s principles and supports life.

We believe that smart materials are the answer. In an evolving world, where humanity plays an ever-increasing role, we are convinced that the materials we make can no longer be inert and indifferent... to their environment (like plastic), but must instead be adaptive, responsive and agile. Searo® Materials are therefore smart: they can be engineered for diverse applications to respond to the environmental challenges we face, as well as the needs of consumers and industry.

Food waste is a problem we are set on solving with material technology. By utilising the unique properties of our film, we can package fresh produce to achieve extensions in shelf-life. Searo® Materials are inherently... breathable, and this allows them to act as a natural, permeable barrier which expels excess moisture from food and can prevent mould growth and spoilage. Cutting food waste — and the pressure it puts on supply chains — is one of the things we care most about, and we keep pushing what packaging materials can do.
