How does a city create a valuable resource out of its organic domestic waste? State-of-the-art waste recycling at Bulla

THE CHALLENGE

With less viable sites to bury domestic waste, diverting waste from landfill in a sustainable

way has become an increasing issue for 11 councils in the north and west of Melbourne.

THE SOLUTION A new organic green waste facility at Bulla, about 30 kilometres from Melbourne, that uses state-of-the-art Australian technology to turn thousands of tonnes of green waste into high-grade compost for agriculture.

It processes on average about 85,000 tonnes of green waste every year, including bush trimmings, lawn clippings and small tree parts.

HOW WE DO IT

Using technology developed by Veolia and its partners, kerbside garden organics are pre-sorted to remove contaminants and then

shredded to a suitable size for composting. The shredded materials are enclosed in concrete vessels, with plenum floor and undergo an

intensive composting process under controlled conditions where oxygen content, temperature, air-flows and pressures are controlled

by a computer based management system.

A controlled aerobic and thermophilic biological transformation achieves pasteurization and destroys pathogens and weed seeds.

The aerobic facility generates no methane (as apposed to traditional

landfill) and turns green waste into useful high-grade compost.
