Description of key information
Fast Pyrolysis Bio-oil is not known to contain components that may be reactive with water (susceptible to hydrolysis), and while its dark colour indicates the presence of chromophoric structures and therefore at least some potential for photolytic degradation, biodegradation is most likely the major route of dissipation in the environment. According to testing results, Fast Pyrolysis Bio-oil cannot be considered readily biodegradable, but it can probably be classified as inherently biodegradable and its biodegradation is faster and more effective than that of fossil fuels (Blint et al., 2007).
Ca. 50 % of Fast Pyrolysis Bio-oil consists of water-soluble compounds (sugar-type compounds, acids, aldehydes, ketons, pyrans and furans) which are mobile in soil and the aquatic environment. Ca. 6 % consists of lipophilic compounds (fatty acids, triglycerides, sterols, resin acids, sesquiterpenes, polycyclic aromatic hydrocarbons) whose mobility may be restricted by sorption to organic matter. Volatile alcohols, acids and aldehydes and small molecular weight PAH compounds may evaporate from Fast Pyrolysis Bio-oil; according to the experience of consortium members, the main volatile components are acetic acid and furfural.
Components of high lipophilicity which may bioaccumulate in the tissues of organisms (long-chain fatty acids, PAHs, sesquiterpenes, phytosterols) form ca. 4 % of Fast Pyrolysis Bio-oil.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
