A circular economy - the future of waste management in Victoria

Star Dam Rehabilitation

The Calleja Group is starting the rehabilitation of its Star Dam site, which will kickstart the renewal of Parwan Creek – up to 20 years ahead of schedule.

By investing in the rehabilitation of the disused quarry and mine MBC will create a wetland that will become a major habitat for the endangered growling grass frog.

COLDry and MATMOR technology

With the coal mine continuing to produce coal for a range of fertilisers and soil conditioners, the Calleja Group has worked for more than two decades to develop two patented technologies, COLDry and MATMOR, to enhance the use of brown coal as a fuel and as a reductant to produce steel.

To assist this complex process, Calleja constructed two pilot manufacturing plants at JBD in 2003, with the objective to develop the technologies for future commercialisation. Once proven, the patents were sold to Environmental Clean Technologies Ltd (ECT), a Melbourne listed company. ECT now operates the pilot plants at JBD.

Innovative management of environmental impacts

MBC has many measures in place to protect our water, air and soil and to limit litter as part of our commitment to minimise impacts of operations on the environment.

We use innovative materials recovery technology to sort through all the waste that comes to the site in order to recycle as many materials as possible.

The MBC Soils composting facility ensures that green waste is reused rather than disposed of in landfill.

We are actively engaged in research into organics processing and use advanced technologies to maximise re-use and resource recovery.

Landfill Gas

MBC has a series of wells installed in the closed landfill cells, as well as a flare to destroy the Landfill Gas (LFG) captured in the wells to create Australian Carbon Credit Units (ACCUs). One ACCU equates to one tonne of carbon destroyed.

The rights to the LFG currently being created by decomposing waste in the closed cells at MBC is owned by a third party who will continue to install wells to create LFG from future landfill cells.
