Coal tar is a byproduct derived from the coking, coal gasification or liquefaction processes of bituminous coal. It is a complex mixture of phenols, polycyclic aromatic hydrocarbons (PAHs), and heterocyclic compounds, characterized by its black, viscous appearance. Coal tar is processed for the production of tar-based products, compliance with industry standards, and may be used in medical treatments, roofing applications, or as a base for coatings and sealants. The flow of coal tar in the LCA includes details on its treatment, quality, usage, its educt being bituminous coal, and whether it is supplied as a production or consumption mix, potentially 'to consumer' or 'at plant', with details on each aspect separated by commas.
