Koppers Newcastle beneficially reuses coal tar from Australian steelworks to produce coal tar pitch, an essential raw material for Australian aluminium smelters. It also produces carbon black feedstock oil, naphthalene, and timber preservation creosote which are sold domestically and exported. Its Mayfield plant has been successfully operating for more than 50 years and employs around 60 local people.
