Maddingley Brown Coal

The Calleja Group acquired the Bacchus Marsh-based Maddingley Brown Coal Mine in 1990, with the aim to use the mine’s 13.5 million cubic metre void as an EPA-licensed landfill site. The original MBC landfill is nearing approved final waste elevations. Stage 2 EPA- approved cells have recently commenced operation. MBC receives inert (C&D and C&I) waste a year, sourced from the Calleja Group’s transfer stations in Altona and Coburg, as well as the company’s fleet of trucks which cart waste direct to MBC. MBC forms part of the broader, Calleja Group landholding in Maddingley. Current activities at the landholding include mining, landfill, soil conditioning (composting and soil recycling), potential acid sulphate soils (PASS) disposal – as part of a plan to rehabilitate the disused Star Dam site into a habitat for the critically endangered growling grass frog – as well as cropping and grazing.
