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

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
