These rapidly renewable aquatic plants offer an exciting frontier in materials innovation, providing health and environmental benefits and are biodegradable at the end of use, all while eliminating reliance on fossil fuels.

One of the most compelling advantages of algae-based materials is their ability to grow without requiring arable land. Unlike traditional crops, algae cultivation does not compete with food production, preserving essential land resources. Additionally, algae and seaweed contribute to environmental health by absorbing carbon dioxide through photosynthesis. This natural process helps mitigate climate change by reducing atmospheric CO2 levels.

Seaweed, also known as kelp or macroalgae, plays an essential role in marine ecosystems. It provides habitat and nourishment for marine life and helps combat ocean acidification. These plants are also healthy ingredients for sustainable material development, with applications in textiles, foams, dyes, and biodegradable packaging.

Both macroalgae (seaweed) and microalgae (single-celled marine organisms) can serve as sustainable biomass sources for material innovation. Microalgae, in particular, have high oil content, making them a viable replacement for petrochemical-based oils. The potential applications for these marine-based materials span across industries, from construction and packaging to textiles and pigments.

By harnessing the natural properties of these plants, designers and manufacturers can create materials that not only benefit human health but also support regenerative ecosystems. As research and development progress, the possibilities for ocean-based materials continue to expand.

Several forward-thinking companies are already utilizing seaweed and algae to create healthier, sustainable materials. Following are a few examples that meet our rigorous evaluation standards

• Agoprene – A kelp-based foam alternative
• Kelsun by Keel Labs –  textile fibers derived from seaweed 
• Loliware – Algae-based biodegradable packaging
• Notpla – Food container packaging made with algae coating
• Ocean Ink by Oceanium – A pigment made from marine resources
• Other Matter - Decals made of Algae to replace vinyl
• Søuld - Acoustic panels, boards and mats of eelgrass 
• Sway – Seaweed-derived flexible packaging, including window films
• Zeefier – A bio-based dye derived from seaweed

For designers and manufacturers looking to integrate ocean-based materials into their projects, we provide detailed guidance on specification and sourcing. Transitioning away from petroleum-based products is a crucial step in creating healthier environments, and these marine-derived alternatives offer a path toward a more regenerative future.

By investing in materials that support ecological balance and human well-being, we can move toward a design industry that values health, sustainability, and innovation. The sea holds immense potential as an ecosystem that can support and shape healthy material futures.

We invite you to join us for our upcoming virtual event on March 25th at 12pm ET, Marine Materials: Designing the Future with the Ocean.  We hope to see you there!
