LANDFILL EXCELLENCE AWARD

Bundaberg Regional Landfill
Bundaberg Regional Council

The Bundaberg Regional Landfill was opened on 26 June 2007. It is an innovative, technologically advanced and environmentally conscious site, which aims to surpass ‘expected’ standards.

At the time of the initial development application, the Council was advised by the Queensland Government’s Environmental Protection Agency that a 600mm-thick clay liner was acceptable for the volumes anticipated in the landfill. The Council, however, chose to upgrade these requirements to a composite of 1.5mm HDPE and 900mm-thick clay liner. By doing more than what was necessary, and by setting high internal expectations, the Council has managed to develop a landfill that sets new standards in waste disposal facilities.

The Council sought to address community concerns by considering all social and environmental impacts requiring an eight-year design and approval process that resulted in a fully composite lined putrescible landfill to service less than 45,000 tonnes of waste a year. The site features many unique elements that make this landfill particularly gentle on the environment including bird netting over the leachate pond to prevent wildlife accessing contaminated water, as well as aiming to have no off-site water discharge.

The site is part of a significantly greater waste minimisation and recovery system that operates across the entire Bundaberg Region, encompassing six transfer stations and some smaller landfills. No waste is deposited directly at this facility that has not gone through one of Council’s network of transfer stations.

All resource recovery and waste minimisation practices have been exhausted by the time waste arrives at this facility.


Buttonderry Waste Management Facility
Wyong Shire Council

Wyong Shire Council owns and operates the Buttonderry Waste Management Facility (BWMF) – the only operational landfill site in the Shire. The site has operating landfill cells, closed cells, a composting facility, a transfer station and all associated infrastructure including a main office. The BWMF landfill opened in 1990 and covers an area of 270 hectares. Approximately 200,000 tonnes of waste are received each year – 64,000 tonnes are recycled and recovered and 136,000 tonnes are deposited to landfill.

Council has established a best practice facility utilising a combination of state of the art practices, effective management systems and new technologies.

Over the last 18 months, Wyong Shire Council has been implementing a Best Practice Management Strategy with the aim of increasing the life span of the site and to ensure that any impacts on the surrounding environment and the community are minimised.

 The actions taken include, but are not limited to:

  • providing daily, weekly and monthly reporting of environmental compliance;
  • compulsory monitoring of surface gas, groundwater and stormwater; and
  • monitoring and analysing the chemical composition of water quality in sediment ponds, of the leachate and the quality of the subsurface gas.

Vegetative buffer zones around the site visually conceal the site and contain dust and litter. These zones create a physical barrier in the event of subsurface methane migration and protect endangered flora and fauna along the creek line.

Major roads in and out of the facility are sealed, whereas minor roads are constructed with crushed concrete and shale. Every vehicle that travels on the few unsealed roads have their wheels washed at the mechanised wheelwash before leaving the site.

Additionally, Council has built a waste transfer station on the site for the general public to unload their waste. The transfer station is divided into sections to allow the general public to separate their recyclable materials into each of the designated areas to ensure as much material as possible can be recycled or reused.

In 2011/2012 Council’s contractor doubled the capacity of the Buttonderry Waste Management Facility methane gas extraction program by installing an additional 1.1 MW generator.

In early 2013, gas extraction increased from 750,000m3 per month to over 1,000,000m3, creating enough energy to power around 4000 households.

TRANSFER STATION EXCELLENCE AWARD

Molendinar Waste and Recycling Facility
City of Gold Coast

The City of Gold Coast has a population of 538,300 (2012) and caters for up to 11 million
visitors per annum.

The Molendinar Waste Transfer Station and Resource Recovery Centre is the first of the City’s new large scale waste and recycling facilities, servicing more than 210,000 customer transactions per annum with peak vehicle movements of up to 1,300 vehicles per day.

The facility is located on the site of a former landfill that has been decommissioned. Decommissioning and remediation of the closed landfill site incorporated the placement of a low permeability capping and overlying planting medium, tree planting and construction of a landfill gas (LFG) collection system that provides LFG to a power generator, which feeds “green” electricity back to the grid. Leachate management incorporates the use of re‐injection and direct discharge to sewer. Both the LFG and leachate management systems are monitored using SCADA systems.

The facility incorporates best practice in design, including a dedicated front end resource recovery area, weighbridge, drop off areas for the recovery of greenwaste and construction and demolition waste, a shallow push‐pit for the receipt of dry general waste and secondary resource recovery opportunity at the ultimate disposal area.


Dalby Waste & Recycling Centre
Western Downs Regional Council

The landscape surrounding the Dalby Waste & Recycling Centre is dominated by rural activities such as the Queensland Cotton cotton gin & cropping land. The site fronts the gateway to the west, the Warrego highway.

The Centre plays a vital role for managing waste streams generated in Dalby and the surrounds. By directing waste through the Centre rather than sending it directly to landfill, there is greater opportunity for the recycling and reuse of materials, ultimately reducing the amount of waste needing to be transported and disposed to landfill.

Upon entry to the Centre, all customers are directed to initially pass through the active resource recovery area. In this area, customers are provided with the opportunity to unload any materials that are recyclable and/or reusable prior to reaching the residual waste transfer station building.

Adjacent to the active resource recovery area is the roofed Recycling Market, where reusable materials are sold to the general public.

Additionally, the Centre provides a fenced enclosure for the receiving and storage of containers and drums under the National DrumMuster Program. The success of this program throughout the Western Downs Region is not surpassed by any other local government. The new facility at Dalby is strongly supported with several thousand drums already collected.


Burnie Transfer Station & Resource Recovery Facility
Transpacific

From 20010‐2012 Transpacific worked with Burnie City Council to develop an alternative waste solution to their old landfill, which was due to close. The solution was the Burnie Resource Recovery and Waste Transfer Station.

The facility plays a pivotal role in the community, receiving waste and recyclables from the surrounding region, and diverting a high proportion of waste from landfill. The facility is safe and user friendly, with a simple yet brilliantly conceived design layout allowing for one way traffic around the site and promoting longevity.

Resource recovery is promoted before the customer enters the gate, with a staggered pricing structure encouraging users to separate their loads. Commercial users benefit from this pricing structure as well, and as a result, resource recovery has seen a marked increase over the previous landfill.

Transpacific was able to offer this sophisticated solution at a reasonable cost to consumers its pre‐established waste transfer network, ensuring that waste and recyclable transport is as efficient as possible.

Transpacific’s Burnie operation manages potential environmental issues by carrying out all waste management activities within an enclosed building and/or on a sealed surface. By utilising this method, the majority of issues are effectively engineered out before having any opportunity to develop.

The Resource Recovery Facility has been designed to be under cover, so not only to reduce the mix of rainfall into the separated waste but to also allow a comfortable area for community to unload.

A range of best practice management, monitoring and contingency procedures are also employed on‐site to ensure potential environmental impacts are minimised, controlled or quickly rectified.

INNOVATION AWARDS

Genesis Recycling and Landfill Facility
Dial-A-Dump Industries

The Genesis Recycling and Landfill Facility is a fully integrated recycling and landfilling facility specialising in the recycling of building and demolition waste recovery at the Material Processing Centre (MPC).

This is a one-of-a-kind facility, with no other facility of this type existing in Australia. The facility’s focus on reuse and recycling is aligned with the Waste Avoidance and Resource Recovery Act 2001, drawing on years of industry experience in constructions and demolition waste.

Genesis has utilised cutting edge technology with the recycling plant to process and segregate waste for higher and better use. It employs state of the art technology with a designated materials processing centre and re-engineered landfill quarry, with a capacity to receive up to two million tonnes of material per year through the custom engineered chute running from the materials processing centre down into the landfill quarry.

Additionally, the entire site is irrigated on all trafficable areas, which are concreted. In addition to the holding dams on site, which hold over 6,000,000 litres of water for reuse, there is also a 1.5 million litre water storage tank located under the building to separately collect all road water for reuse.


Prototype of Solar Distillation and Leachate Disposal by Irrigation
Hanson Landfill Services

The Prototype of Solar Distillation and Leachate Disposal by Irrigation project utilises solar distillation to partition the leachate into an ammonia rich distillate and brine. The use of solar distillation panels for treating leachate from a landfill has never been trialled before.  The use of the ammonia rich distillate for irrigation on the capping is also unique.

The Carocell distillation units used can efficiently use solar radiation to evaporate leachate and recondense the vapour to trap nitrogen in the form of ammonium carbonate.

The project uses the natural nitrogen cycle to treat the ammonia by using the distillate for irrigation and allowing the plants and soil biota to take up the nitrogen and release nitrogen gas. Implementing this on a landfill site uses the landfill capping to ensure all treatment is effectively on-site with no discharge to the environment.

Further benefits of the system include being very low cost, low energy and low maintenance; and if any energy is needed, green energy from the landfill gas power station can be used.

In terms of long term benefits, the residual ammonia is constantly being reduced. Ammonia levels build up in landfill leachate over time and are one of the long‐term risks to the environment.


Rocklea Transfer Station
REMONDIS Australia

REMONDIS Australia (previously Thiess Services) was the first organisation to operate High Volume Side Tipper (“HVST”) trailers within Australia. The first of the fleet were deployed to operate out of the Rocklea Transfer Station with the current version of the B Double HVST combination being introduced to the fleet in 2011 / 2012.

The staff at Remondis partnered with AZMEB Global Trailers to research, develop, design and build the HVST trailers which are now being used by many waste companies across Australia.

The transfer of waste from transfer station to landfill is a recurring operation that provided opportunity for improvement through innovation. Such innovation has lead to significant social, economical and environmental improvements.  Some examples of the improvements include the following:

  • Fewer truck movements to transfer the same volumes of waste
  • Reduced environmental impact as a result of fewer truck movements
  • Lower maintenance costs over the life of the HVST trailers when compared to walking floor trailers
  • Cost and time savings due to reductions in unloading times
  • Improved health and safety outcomes as the waste transfer process no longer requires the driver to exit their vehicles

The previous walking floor trailers typically took up to 30 minutes to unload approximately 24 tonnes of waste at the landfill.  The HVST B Double trailers are able to unload 38 tonnes of waste within 5 minutes.

The Rocklea Transfer Station along with other Remondis depots now showcase HVST B Double and Single trailers in their fleet of waste transfer trailers.


Eastern Creek Leachate Riser Modifications
Waste Assets Management Corporation

The Waste Assets Management Corporation (WAMC) was established to own and operate several landfill sites that were formerly owned by WSN Environmental Solutions (WSN), following the sale of WSN to the private sector in 2011. WAMC is responsible for the management of two operational landfills – Eastern Creek Waste Management Centre and Belrose Waste Management Centre, along with the rehabilitation and aftercare of several closed landfills across Sydney’s metropolitan region.

WAMC experienced issues with uncontrolled and significant landfill gas releases from the vertical leachate riser systems, with impacts on leachate level control and damage to leachate pumping hardware.

Over a 12 month period, WAMC worked closely with a specialist process engineering consultant – JPG Engineering – to develop an effective leachate riser system design and operating regime.

The current modifications to the old leachate riser enable the landfill gas and leachate to be managed separately and in concert, allowing effective operation of the pumping leachate system, which resulted in the leachate level within the riser to be lowered, substantially increasing landfill gas extraction.

Additionally, the modifications resulted in improved environmental, social and economic benefits, with a 115%-175% increase in gas capture. The benefits include reduced odour, reduction in fugitive landfill gas emissions around the leachate riser and increased power generation.
