CO2kvoodidest

CO2kvoodidest is a term used in some environmental materials literature to describe a class of processes that convert carbon dioxide into solid, wood-derived carbon materials. The concept blends CO2 capture with the use of lignocellulosic feedstocks to form carbon-rich products that can range from biochar-like solids to porous carbon networks.

In typical implementations, CO2 is introduced into reactors containing biomass-derived precursors and catalysts, at elevated temperature and pressure. Through reactions such as carboxylation, dehydration, and polymerization, carbon dioxide becomes chemically fixed within a carbon matrix, yielding materials whose porosity and surface chemistry can be tuned by process conditions.

The resulting materials include carbonized biomass, wood-derived carbon foams, and activated carbons suitable for adsorption, catalysis supports, or electrodes for energy storage. Their properties depend on feedstock composition, temperature, residence time, and catalysts used.

Potential advantages include the provision of long-term carbon storage and the valorization of waste wood. When powered by low-carbon energy, the approach can contribute to net negative emissions or reduced lifecycle greenhouse gas footprints. However, challenges remain in energy intensity, cost, scalability, and material stability under cycling or environmental exposure.

Research on CO2kvoodidest is ongoing, with assessments focusing on lifecycle analysis, feedstock logistics, and integration with existing biorefinery or CCU infrastructure. Related topics include carbon capture and utilization, biochar, and wood-derived carbon materials.
