Northern Areas Waste Management Authority

Uleybury Landfill

NAWMA's Uleybury landfill receives only domestic waste or residual industrial waste that cannot be effectively recycled, re-used or recovered.

NAWMA is implementing the world's most advanced system for baling this domestic and industrial waste prior to it being transported to the Uleybury landfill.

Bales are placed in the landfill in stages and progressively filled. Based on receiving 100,000 tonnes of baled waste per annum, the landfill will have an operational life of 16 years.

Uleybury is a best practice landfill site. It features leading edge monitoring and controls to protect the surrounding environment and natural groundwater. The management systems include:

an engineered clay and synthetic liner to form a barrier between the base of the landfill and groundwater. Leachate collection systems are also in place;
a network of groundwater monitoring bores with regular sampling and testing to monitor for any leachate seeping into the surrounding water table;
surface water management and controls; and
commitment to on-going monitoring of groundwater bores following closure of the landfill.

Landfill gas management strategies are being implemented at the Uleybury landfill to ensure that:

gas concentrations are within accepted safety levels in site buildings and surrounding areas;
greenhouse gas and odorous emissions are reduced; and
trace impurities or toxins do not pose a risk to the community or employees on site.

Once landfill gas is extracted, it can be safely flared or utilised for power generation. Each year, the extraction of gas from the site will abate over 38,000 tonnes of greenhouse gas emissions. This is an annual equivalent to taking about 9,000 cars off the road, reducing the use of over 100,000 barrels of oil, or the planting of nearly 4,000 hectares of trees.

Landfill gas extracted from the NAWMA site will produce approximately 1MW of renewable energy. This is enough to power over 1,000 homes.
