Technology Portfolio

One platform process
built around C-PCC

We extend the principles of C-PCC — proven through government demonstration and patents — calcium recovery, CO₂ conversion and materials making, to oyster shells, process residue and CO₂ storage.

Platform Logic

INPUT → PROCESS → OUTPUT

INPUT

Waste · CO₂

Oyster shells (first commercial feedstock)
Steel slag · CBS dust · desulfurization gypsum · Class C fly ash (C-PCC demonstration feedstock)
Incineration ash, etc. (feedstock under review)
CO₂ from flue gas · calcination

PROCESS

Pretreatment · recovery · purification · materialization

Feedstock-specific pre-treatment
Calcium recovery · CO₂ conversion
Particle size and whiteness control

OUTPUT

Calcium-based industrial materials

C-PCC · high-purity CaCO₃ (functional filler)
OCC (plastic filler · building materials)
Solid CaCl₂ (de-icing · desiccant)
Construction materials · fill

Technology Readiness

Readiness by technology

We show the current stage of each technology honestly. “Demonstrated” is used only when demonstration or production experience is documented.

Technology	Feedstock	Products / uses	Stage	Evidence · next validation
C-PCC	Steel slag · CBS dust · desulfurization gypsum · Class C fly ash	Calcium carbonate · construction materials	Demonstrated	Special Zone demonstration (2021–23), 5 t/day production verified, 3 KTR tests, supply record
OCC	Oyster shells	Plastic filler · eco-friendly construction materials	Pilot	Yield, quality and cost on oyster shells to be measured in the 500 t/yr pilot
Bio CaCl₂	Oyster shells	De-icer · desiccant	Development	Prototypes · commercialization preparation (planned for 2028)
High Purity CaCO₃	Oyster shells → industrial by-products	Functional filler · fine chemicals	Development	Test report pending · target of TIPS R&D project
Carbon Mineralization	Process residue + CO₂	Fill material · artificial aggregate	Development	Residue reactivity must be demonstrated by feedstock composition
