What is Fourier
What is 
.
A bio-composite engineered from reclaimed marine bio-minerals and GRS-certified recycled polymers, designed first as a material, then expressed as tableware.
Composition
Engineered, not blended.
The composition is fixed, traceable and audit-ready. Every batch ships with its specification, so a procurement team can defend it without a follow-up email.
Fourier is built from more than 70% reclaimed marine bio-minerals: refined, calcium-rich mineral content reclaimed from ocean-waste streams under chain-of-custody, bound with GRS-certified recycled polymers and a food-contact-grade stabiliser package.
Mineral fraction, polymer lot, certification references: each is recorded against the batch. The material is the spec, and the spec travels with the order.

The process
Ocean waste to surface, in five steps.
Reclaimed at source, refined to a consistent feedstock, compounded to a fixed specification, formed, and verified before it ships.
Reclaim
Calcium-rich ocean waste captured under chain-of-custody, diverted from landfill at source.
Refine
Cleaned, milled and graded into a consistent calcium-rich bio-mineral feedstock.
Compound
Blended with GRS-certified recycled polymer and food-contact stabilisers to a fixed specification.
Form
Moulded into bowls, plates, GN dishes, mugs, trays and cutlery.
Verify
Independently tested, documented, and shipped with the full compliance file.
