Planet Smart is a deep tech startup based in London, specializing in the development of advanced biomaterials. The company's primary innovation is PlanetSorb, a biodegradable superabsorbent polymer intended to replace traditional fossil-based plastics in sectors such as hygiene, agriculture, packaging, and mining waste management. Founded by Dr. Gerald Marin and Maurice Rüttimann, Planet Smart aims to eliminate microplastic pollution through sustainable, high-performance design.
The biomaterials and hygiene sectors face significant challenges, particularly concerning the environmental impact of fossil-based plastics used in products like diapers and sanitary pads. These materials contribute to microplastic pollution, a growing environmental concern. Regulatory bodies and consumers are increasingly demanding sustainable alternatives. PlanetSorb addresses these needs by offering a biodegradable solution that matches conventional materials in performance and cost-effectiveness, facilitating a transition away from microplastic-producing materials.
In 2025, Planet Smart transitioned from a research-focused initiative to a fully operational biomaterials company. The company secured $1 million in pre-seed funding from investors including General Inception and Vertical Venture Partners. This funding supported the launch of PlanetSorb, expansion of research and development operations, and the commencement of commercial trials with global hygiene manufacturers. The company has achieved market traction with four letters of intent from major manufacturers and two purchase orders from European brands, backed by independent testing affirming PlanetSorb's compliance with industry standards.

In 2026, Planet Smart aims to scale its production capabilities to achieve an annual output of one kilotonne, equivalent to the production of around 45 million nappies. The company plans to strengthen its commercial partnerships and integrate PlanetSorb into mainstream products while exploring new applications in agriculture, wound care, packaging, and mining waste management.
