Biochar is a solid material obtained as the product of carbonization of biomass. This ma­terial can adsorb fatty acids, thus unfolding a potential application as hydrophobic adsorbent for use in water and air purification systems. Despite biochars possessing a relatively hydro­phobic core, they are wetted by water due to such hydrophilic functional groups as carboxylic acids, aldehyde, and hydroxyl on the surface (Mursito, Hirajima et al., 2010), so these biochars may be useful as reenforcing additives in cement and organic polymers. The low ash content of carbonized char (Heilmann, Jader et al., 2011) also points to potential application as a car­bon source for production of synthesis gas or as an alternative to coke in steel manufacture. This material may be easily stored in subterranean locations, thus entailing a form of carbon sequestration; it may also be applied in soil amendment, since it is rapidly attacked by soil microorganisms (Heilmann, Jader et al., 2011).
