Technology & Products
Key Products
PHAbulous Philaments (PHA 3D printing filament); Legumino® (Rhizobia inoculant for agriculture); Custom bioplastic compounds
Technological Advantage
CLAIMED: 100% compostable, non-toxic, 60-day soil degradation, fertilizer byproduct. VERIFIED: PHA chemistry is scientifically established; 2015 Kickstarter validated market demand; SOSV/RebelBio accelerator backing. DEFENSIBLE: Proprietary microbial strains and fermentation optimization (trade secret), though PHA polymer class is public domain.
Differentiation
Value Proposition
Eliminates toxic additives and microplastic pollution by providing a fully compostable, non-toxic 3D printing filament that degrades in soil within 60 days while acting as a fertilizer, reducing environmental liability and aligning with circular economy mandates.
How They Differentiate
Unlike standard PLA or ABS filaments that require industrial composting or leave microplastics, Saphium's pure PHA filament degrades in ambient soil within 60 days and enriches soil. Compared to bulk PHA resin producers (e.g., Danimer), Saphium focuses on ready-to-use, extruded 3D printing filament formats optimized for direct AM applications.
