The production of biochar, a type of charcoal made from animal wastes and plant residues (such as wood chips, leaves, and husks), can sequester carbon by circumventing the normal decomposition process or acting as a fertilizer to enhance the sequestration rate of growing biomass.
In the scientific literature, it has been highlighted that while CO2 emissions from land use change account for as little as 6 17% of total current CO2 emissions [8], forests and the land use sector can play a key role in reducing emissions to the atmosphere, enhance the sequestration of carbon in terrestrial reservoirs, and substitute carbon intensive products.
These observations suggest that engineered biofilm barriers may be used to enhance the geologic sequestration of atmospheric CO2.
Alternatively, sequestration of β-carotene into crystals may shift local chemical equilibria, thus enhancing the flux of carbon through the pathway.
Enhancing the solubility of CO2 in formation water has always been the focus of research in the area of CO2 sequestration.
Results demonstrate that (a) low tetracalcium aluminoferrite (C4AF) cements, (b) compressive strength, (c) high CO2 exposure, (d) no SCMs, (e) time, (f) high SA/V ratios, and (g) indoor environments enhance the in situ carbon sequestration of exposed OPC concrete.
The mineralogical compositions and microstructure changes of the carbonated samples characterized using X-ray Diffractometer (XRD), X-ray Fluorescence (XRF), Scanning Electron Microscopy (SEM) and Diffraction Spectrometer (EDS) showed that addition of mineral kaolin to sandcrete enhanced the rate of CO2 sequestration.
In particular, receptors that promote rolling adhesion [such as ICAM1, vascular cell adhesion molecule 1 (VCand) and P-selectin] might act synergistically with static adhesion receptors such as CD36 to enhance the overall degree of sequestration in vivo (Refs 54, 55, 56).
