Based in the state’s northwest, Dulverton Waste Management processes roughly 60,000-70,000 tonnes of waste annually.

The company prides itself on being a ‘leader in holistic waste management’ and manages Tassie’s largest composting facility, handling around 30,000 tonnes of organic waste per year.

Dulverton’s composting process follows strict environmental guidelines, involving placing physical caps on waste piles several times a year to prevent contamination of the surrounding soil.

"Unlike many sites that only cap their landfills at the end of the cell life, we use a different capping methodology which is to cap two or three times throughout the year to keep leachate generation to a minimum," Dulverton Waste Management CEO Mat Greskie says.

Capping a landfill site is a time-consuming process, so to do it two or three times a year presented a significant challenge to Dulverton.

"Regular capping means more frequent surveying to peg out the grade for operators to follow. The process was labour-intensive and frustrating," Greskie says.

"The surveyors would then come back, often multiple times, and have to re-peg the grade and the cycle would start again."

To get around this double-handling, Dulverton bought a Carlson LandfillGrade control system from distributor Position Partners and had it installed on a Bomag BC772 RB-2 compactor.

The Carlson system allows operators to work to a pre-determined design and view compaction and grade information in real time.

Greskie says the Carlson LandfillGrade system appealed to them as it was designed specifically for waste management.

"We chose Carlson because, unlike other solutions in the market, it has been designed specifically for landfill applications rather than adapted from an earthmoving solution," he says.

 "Our operators have certainly embraced the technology and find it very easy to use; it’s given them the confidence to know they are placing the waste to design and compacting the waste consistently.

"Introducing landfill machine guidance has certainly helped us to pack as much waste into every cubic metre as possible," Greskie adds.
