Major waste solution extends our Landfill by 40 years
Published on 13 December 2018
The Rockhampton Lakes Creek Landfill was set to reach its capacity this year, but thanks to an innovative solution its lifespan has been extended for a further forty years.
The ‘Piggy back’ extension project is now underway and will see 12 new landfill cells built on top of the existing landfill over coming decades, with the first cell ready to accept waste in the first half of 2019.
Chair of Rockhampton Regional Council’s Waste Committee, Councillor Neil Fisher said final capping and beautification of the original landfill area is now underway.
“This waste disposal solution is a fantastic result for our community – it will allow us to expand the lifetime of our landfill by an additional 40 years which means our residents have the convenience of using a world class waste facility close to the urban area for a long time to come,” Cr Fisher said.
“The first cell will hold 180,000 cubic metres of waste, or 2 years’ worth, before it is full. We will then move onto the second cell which will be built in the next two years and we will continue this process until all 12 cells have reached capacity.
Cr Fisher said the engineering of the piggy back solution also has a range of environmental benefits.
“The new ‘Piggy back’ cells will use the latest technology in lining systems to ensure that the liquid that is generated as waste decomposes and captured and will not enter the environment.
“It includes a layer of natural clay, a layer of synthetic clay and a layer of 2mm thick plastic liner. These layers combined with geotextiles and stone aggregate as a drainage medium allow this liquid to be captured and treated.
“Landfills also produce methane gas as part of the decomposition of waste, and by using proven technology, this gas is captured and used in a way to produce electricity once viable.”
As well as the Piggy Back construction, a green buffer is being established with 2400 native trees recently planted along one kilometre of the frontage and entrance of the facility. This green buffer will provide additional screening for the residents and traffic along Lakes Creek Road.
