Science & Material Landscape

Biofoam development draws on several material families. Each has different strengths, limitations and typical applications. Performance (mechanical properties, durability, fire behaviour, thermal insulation, processing compatibility) remains essential regardless of bio-content.

Bio-based Polyurethane

Flexible and rigid foams using renewable polyols (soy, castor oil and others). Can closely match conventional PU in cushioning and insulation when formulated appropriately.

Starch-based Foams

Produced by extrusion or molding of starch. Common in protective packaging. Often designed for compostability, but moisture sensitivity can limit certain uses.

PLA and Other Biopolymers

Foams based on polylactic acid or related biopolymers. Used in packaging and some structural applications.

Cellulose & Lignocellulosic

Derived from wood fibers or agricultural residues. Can support insulation and packaging applications.

Mycelium-based Composites

Fungal mycelium grown on agricultural waste forms a lightweight material. Fully bio-based and frequently compostable. Used for protective packaging and some insulation panels.

Higher bio-based content does not automatically mean higher quality. Fitness for use, durability and safety remain central evaluation criteria.
