Innovation in grease trap waste management is driving growth for REMONDIS in Victoria
REMONDIS Australia // 23 April 2025
REMONDIS’s liquid processing plant at Dandenong South is one of the most efficient and complex liquid treatment facilities in Australia
With new technology under development, we’re on a mission toward 100% diversion from landfill for grease trap waste, while creating new value in biofuels
And in the meantime, digital innovation is speeding up disposal logistics
SERVICE FOCUS
Poya Assadi, REMONDIS Australia’s General Manager for Victoria, is on a mission toward 100% diversion from landfill for grease trap waste, while creating new value in biofuels.
Poya’s specialised liquid waste management team services thousands of grease traps across greater Melbourne, including restaurants, hotels and food manufacturing facilities.
REMONDIS’s liquid processing plant at Dandenong South also receives and processes liquid waste from third parties, including leachate, stormwater, wash waters, oily waters, grease trap, plus industrial waste waters containing caustic soda and sulfuric acid.
It’s one of the most efficient and complex liquid treatment facilities in Australia, providing services along the full value chain from collection to processing, resource recovery and disposal.
When it comes to servicing our grease trap clients, trained technicians operating specialised liquid vacuum extraction vehicles remove the waste from the client’s grease trap and transport it under license to REMONDIS’s dedicated processing facility. On arrival, it’s logged for regulatory compliance, filtered to remove contaminants, and then separated into clean water returned to the public water authority, and organic cake. The cake is used by organics composting facilities as an additive to the composting process.
Some local competitors send the organic cake to landfill, which is an option in Australia but not a solution REMONDIS supports. Our approach delivers a largely closed loop, but Poya is not satisfied – he’s currently developing a more advanced processing approach using German technology to recover the heavy fat component as brown grease, a highly valued biofuel.
“Fat is a resource. It’s a valuable commodity and we must treat these materials accordingly to enable the circular economy,” says Poya.
Digital innovation
While this processing innovation is in confidential development, Poya has turned his attention to service innovation via digitisation.
The team developed a digital application to speed up the mandatory registration of liquids being disposed at their facility, transforming a time-consuming manual log into a digital form completed on a tablet in minutes. The time saving creates a competitive advantage for the facility, which has a growing reputation for fast, trouble-free disposal.
All customers of REMONDIS in Australia have access to a digital Client Portal for 24/7 online access to their service history, volumes and invoices. Adding more value to this asset, Poya’s grease trap technicians upload photos of the client’s trap before and after each service, providing a visual record of a job well done.
'Goldilocks' liquid vacuum fleet
REMONDIS’s liquid logistics fleet has another unique advantage – right-sized vehicles. The Victorian liquids fleet includes four small tailor-made vacuum extraction vehicles, perfectly sized for urban locations including tight loading docks, underground car parks and other tight-access, low entry environments.
Conventional 8,000 litre capacity vacuum extraction vehicles can’t gain access to the client’s grease trap. But send a truck which is too small, and the client is disrupted by multiple visits. REMONDIS’s tailor-made low entry trucks can service most clients, including shopping centres and complex hospitality venues, with a single, efficient visit.
Asked what he wished his clients understood about grease trap management, Poya says “it’s absolutely not a service you should postpone”. Delayed servicing can lead to overflowing pits and broken pumps, which is catastrophic for the business and for the wider sewer system when the pit is breached. “It’s costly, and disruptive, and you might be fined. Just stick with the schedule recommended by the authorities and we’ll be there to get it done right, every time.”
“We take care of all aspects of commercial waste management, so our clients can focus on their main business,” concluded Poya.
