OXMAN’s O⁰ platform introduces a new approach to designing consumer goods that grow, serve their purpose, and decompose in alignment with natural ecosystems. The platform focuses on fully biodegradable, robotically manufactured footwear and textiles.

The innovation relies on polyhydroxyalkanoates (PHAs), a bacterially produced thermoplastic polymer. This material forms the basis of O⁰’s mono-material platform, enabling the creation of products—from shoes to textiles—with diverse physical properties and programmable end-of-life decomposition pathways.

Materials and Fabrication: Sustainable by Design
PHAs are naturally produced by bacteria and are fully biodegradable in ambient environments. They are processed using advanced digital fabrication techniques such as 3D printing, hot melt spinning, and knitting. This versatility allows designers to tune the material’s properties to meet specific needs across stages of production, functionality, and end-of-life decomposition.

The O⁰ platform integrates biomaterial production systems with digital manufacturing to ensure products decompose in ways beneficial to ecosystems. This closed-loop design approach facilitates the production, use, and degradation of products within the same ecological framework.

According to OXMAN, the platform represents a “nature-centric shoe and apparel line, made with 100% biodegradable PHAs. Designed for sustainability, these products break down in most natural environments, leaving no microplastics behind.”

Design and Circularity
The O⁰ shoe platform introduces a new design method rather than a single product. Each shoe begins with a knitted sock base providing flexibility and comfort. External layers, tailored for specific uses such as sneakers or ballet slippers, are 3D printed onto the base. These outer layers enhance functionality, offering reinforcement, cushioning, and durability, while maintaining biodegradability.

PHAs play a crucial role in circular design. As a carbon-rich material, they decompose into nutrients for microorganisms, enriching the soil. However, managing decomposition is essential to avoid ecosystem imbalances caused by the high-calorie content of PHAs, which can promote microbial overgrowth. By fine-tuning material properties and decomposition rates, O⁰ offers a model for balancing ecological and functional requirements.

Implications for Design Disciplines
For product designers, architects, fashion designers, and material researchers, OXMAN’s O⁰ platform highlights the potential of mono-material systems. Using a single material simplifies recycling and reduces waste while supporting innovative designs that meet aesthetic, functional, and sustainability criteria.

Key statistics demonstrate the significance of this approach, like that 92 million tonnes of garments are discarded annually, and that traditional shoes use up to 40 materials, including 33–4,200 “forever chemicals”.

OXMAN’s vision aims to reduce landfill waste and microplastic pollution, proposing a future where products naturally reintegrate into ecosystems.
