Impact
We only call it impact
if we can measure it
CARBON-U's impact is measured as a single chain — waste processed → substitute feedstock used → products made → waste avoided → carbon emissions reduced.
01
Waste processedOyster shells · industrial by-products in02
Substitute feedstock usedReplaces mined · imported raw materials03
Products madeOCC · CaCl₂ · CaCO₃04
Waste avoidedLandfill · ocean dumping · stockpiling avoided05
Emissions reducedQuantified by LCACarbon reduction will be quantified after the LCA methodology is fixed during the pilot. Until then, CARBON-U does not publish reduction percentages.
ENVIRONMENT
Environment
- By-product upcycling — replaces landfill
- Oyster-shell upcycling — replaces ocean dumping and stockpiling
- CO₂ utilization — CO₂ fixed in calcium carbonate
- Low-temperature calcination — aiming for lower energy than high-temperature calcination
- Replacing mined materials with waste-based ones
- Reduced wastewater · reuse of process materials by design
ECONOMY
Economy
- Import substitution — solid CaCl₂ · calcium carbonate
- High-value materials — turning waste into products
- Domestic feedstock — less currency and logistics risk
- New markets — eco-friendly de-icers · bio calcium carbonate
- A Scope 3 reduction lever for suppliers
SOCIETY · REGION
Society · region
- Local production and jobs in Tongyeong
- Using regional resources — industrializing oyster shells
- Solving regional issues — limited treatment capacity · disposal costs for oyster farmers
- Public–private–industry cooperation — local government · fisheries · demand companies
Impact KPI Dashboard
Indicators to be measured
We will collect these indicators once the pilot runs and publish them here. Values are empty because they have not been measured yet.
