Zero-Waste Technology
A circular structure
aiming for zero waste
Sending even what remains after calcium recovery to the next industry as feedstock. CARBON-U presents this not as a finished result but as a design principle and a direction.
Circular Loop
WASTE → … → CONSTRUCTION / FILL
- WASTE — industrial by-products · oyster shells
- SEPARATION — Washing · pre-treatment
- RESOURCE — Calcium recovery
- MATERIAL — Calcium carbonate · calcium chloride
- PRODUCT / MARKET — supplying fillers · building materials · de-icers
- RESIDUAL — Process residue
- CONSTRUCTION / FILL — Construction materials · ground/mine-void fill
Design Principles
What is designed, and what we will validate
| Element | Design / evidence | Status |
|---|---|---|
| Process materials | Recovery and reuse by design | Process design Performance with oyster shells verified in the pilot |
| Process water | Process water reused · zero-wastewater design | C-PCC process feature |
| CO₂ | Flue-gas CO₂ conversion / reuse of process CO₂ | C-PCC demonstrated · Oyster-shell line in development |
| Process residue | Construction materials · ground/mine-void fill | Development & demonstration needed Reactivity varies with feedstock composition |
| Overall residue utilization rate | — | To be measured Published as an impact KPI once measured |
CARBON-U does not claim “perfect zero waste.” We believe measuring and publishing residue utilization by feedstock and application is the real path toward zero waste.
Partners to design the residue path with us
We propose partnerships with buyers of construction and fill materials and with mine-reclamation agencies.
