Carbon Storage via Building Materials

Basics
- This page goes over a method of Carbon Storage that utilizes fixing the carbon / carbon dioxide into materials used for producing buildings
- Thus they are trapped in that building, and usually in a solid form, and thus don't have the cost/dedicated infrastructure needs of Carbon Dioxide Injection, The Risk of Gas Leaks, and the potential volatility of Biochar
Methods
Cement and Concrete
- Certain types of Cement use carbon dioxide in the curing process, and thus "suck it in" (granted need to find a LCA on them due to the Carbon Footprint of Cement )
- Also Concrete Aggregate can be made from Carbonated Mine Tailings
- This is a practical use for the Enhanced Weathering technique
Diamonds
- Synthetic Diamonds are not all necessarily Optical Grade PA-CVD Diamonds
- PCD have useful applications unique to the material
- Opaque MCD can be useful as abrasives conventionally, but if cheap enough could be added to Engineered Stone etc
Elemental Carbon
- Elemental Carbon can be used (Need to find info on how the released Oxygen would impact the world)
- Typically as:
- Carbon Fiber (Either as reinforcement in Carbon Fiber Reinforced Concrete , or in Carbon Fiber Reinforced Composites )
- Carbon Foam
- Charcoal / Carbon Black as Concrete Aggregate
- Graphite
Wood
- Although less dense, and potentially less stable (burning/decomposition/ Indirect Land Use Change ) wood can also act as a carbon sink when used in permanent structures
- Can be used as Lumber or as Sawdust Insulation / Wood Pulp Insulation
- Have a paper doing a LCA of Landfilling Lumber for this purpose
- Not Ideal due to Ash Content long term Re BOAR
Via Synthesized Materials
- Bio-Petrochemistry derived materials such as:
- Conventional Plastics via G2L / Bio-Crude Processing Routes
- Bio-Plastics
- Precision Fermentation derived materials such as Caesin Plastics/Glues, Hide Glue , Spider Silk etc
- Vegan Leather would count in this as well
