Calcara

Transforming shell and seaweed byproducts into high-value ceramic and marble materials — a sustainable replacement for engineered stone benchtops and food-grade porcelain.

5% to MVP
Early Stage
The Problem & Solution

Beautiful materials that heal, not harm

Problems We're Solving
1

Limited value in kina shell waste — not enough to justify collection at scale without a high-value market

2

Conventional engineered stone contains crystalline silica — banned in Australia, hazardous to workers

3

The ceramics and stone industry has no ocean-positive alternative at commercial scale

How Calcara Solves It
1

Increases the value of shell and seaweed byproducts — creating a high-margin material market for ocean-derived waste

2

Non-porous, food-safe material replacing engineered stone in benchtops, tiles, and porcelain products

3

Direct market opportunity in Australia (engineered stone ban expanding) and globally where silica risk is regulated
