2015 Temporary Shutdown Update

Residents should use their bins as usual and the collection of both bins (recycling and general waste) and bulk verge waste will not change.  No additional cost to the member councils or their ratepayers will result due to the shutdown.

 

UPDATE

 

Late November 2015 the composters were fully installed and the Facility was recommissioned and began receiving waste.

 

In March 2016 both composters were emptied to allow the internal inspection of the new shells which showed them to be in good condition.

 

The Facility is now fully operational and performing to expectations.

 


NEW COMPOSTERS BEING INSTALLED

The new composters of Mindarie Regional Council’s (MRC) Resource Recovery Facility (RRF) in Neerabup are currently being installed. The facility has temporarily closed to undergo repairs and maintenance, specifically to replace the composters that developed cracks early after commissioning.
                                           
The RRF opened in 2009, with structural cracks in the composting vessels developing early in proceedings. These cracks were temporarily repaired with minimal interference to the normal operations of the RRF. However, to avoid the possibility of a future composter failure, it has been decided to replace the composters to see the RRF through until the end of its operational life.
 
The two composters, each 65m long with a diameter of 4.5m and weighing 300 tonnes, are a key part of the facility. The composters lie horizontally and slowly rotate to break down the waste and start the maturation process of the compost.
 
The composters and associated gearing have been redesigned to both improve their durability and provide operational efficiencies. The installation of the new composters is now taking place, closing the RRF for an expected 14 week period. During this time, the plant will undergo both scheduled and additional maintenance to minimise future lost production time. Whilst the RRF is closed the waste is being diverted to the Tamala Park landfill site.
 
The two original composters have been removed, cut up and taken away as scrap.

 

 

A 3m section of one of the composters has been retained by the MRC and will be placed adjacent to the Visitors Centre allowing visitors to view the inside of the composters and gain an appreciation of their size.

 

 

The new composters were transported in sections during the early hours of the morning to minimize traffic disruption.

 

 

On arrival they were lifted into position and welded together.

 

 

The composters and associated drives have been redesigned to both improve their durability and provide operational efficiencies giving them a different look to the ones they replaced.

 

 

During the shutdown for the installation of the new composters, the plant will undergo both scheduled and additional maintenance to minimise future lost production time. This includes the replacement of the trommels used to separate the composted material out of the composters from the residue material that is sent to Tamala Park.
 
The RRF accepts 100,000 tonnes of general household waste per year from the MRC’s member councils (Cities of Joondalup, Perth, Stirling, Vincent and Wanneroo and the Towns of Cambridge and Victoria Park) and extracts the organic component (e.g. food waste, garden waste and paper products) from the waste converting it to a composted soil conditioner. The RRF diverts from landfill over 50% of the waste it receives and has contributed significantly to the waste diversion rates achieved by the MRC’s member councils, in particular the Cities of Joondalup and Wanneroo who are the principal users of the facility.
 
BioVision 2020 Pty Ltd built own and operate the Resource Recovery Facility in Neerabup for the Mindarie Regional Council. The company SUEZ environnement (formerly SITA Australia) is a shareholder in BioVision 2020 and is contracted to manage the day to day operations of the facility.  

 

Investigations were undertaken to see if the waste normally sent to the RRF could be diverted during the shutdown to similar type composting facilities, however this was found to be both prohibitively expensive and impractical. Contractual negotiations however will see the lost processing of tonnes caused by the RRF shutdown, being recovered at the end of the contract period. This effectively results in no loss in waste processed and materials recovered for the MRC and its member councils over the contract period.
 
Residents should use their bins as usual and the collection of both bins (recycling and general waste) and bulk verge waste will not change.  No additional cost to the member councils or their ratepayers will result due to the shutdown.
 
In the first 5 years of the RRF’s operation its performance and contribution include:
  • Processed over 471,000 tonnes of waste
  • Diverted over 247,000 tonnes of waste from landfill
  • Produced about 130,000 tonnes of compost or organic soil conditioner (as it is labelled in the trade)
  • Recovered 2,740 tonnes of ferrous metals for recycling
  • Diverted over 6,000 tonnes of coarse heavies (rock and glass) in a trial as road base aggregate
  • About 110,000 tonnes of waste gases, mainly water vapour, are lost in the process
  • Prevented  an estimated 250,000 to 300,000 tonnes of greenhouse gas emissions from entering the atmosphere.
The Mindarie Regional Council (MRC) is one of WA’s largest waste management authorities assisting its member councils (Cities of Joondalup, Perth, Stirling, Vincent and Wanneroo and the Towns of Cambridge and Victoria Park) manage their waste. Operating the Tamala Park waste facility and the Resource Recovery Facility in Neerabup, it accepts approximately 350,000 tonnes of waste per year from its member councils, commercial operators and other groups.
 
The MRC’s vision is Winning Back Waste, recognising that waste is a valuable resource. The MRC is committed to managing waste in line with the waste hierarchy and in a way which is sensitive to the environment and protects future generations. The RRF was one of the first projects of its kind in the State being designed to divert waste from landfill and convert it to a composted soil enhancer.
