Technology options

Where are we now?

Until recently, four technology options were being considered for the proposed Resource Recovery Facility at Red Hill: anaerobic digestion, combustion, gasification and pyrolysis. However, at EMRC's 18 August 2011 Ordinary Council meeting, Council resolved to limit the technology options for the proposed Resource Recovery Facility at the Red Hill Waste Management Facility to anaerobic digestion and gasification, therefore eliminating pyrolysis and combustion as possible options.

Why have the changes to technology options been made?

This decision was based on information received from acceptable tenderers during and after the Expressions of Interest phase, preparations for the environmental impact assessment, community engagement feedback and advice from the Environmental Protection Authority during the preparation of the Public Environmental Review.

Anaerobic digestion and gasification are proven technologies for processing municipal waste with many examples world-wide. At this stage, they have been assessed as preferred options for the Red Hill Resource Recovery Facility.

Reducing the technology options from four to two will facilitate a streamlined environmental impact assessment process and refine the project's ongoing community engagement process.

Preparation of Public Environmental Review

In partnership with our six member Councils, Eastern Metropolitan Regional Council (EMRC) is preparing a public environmental report to assess the potential environmental and health impacts of the proposed Resource Recovery Facility at the Red Hill Waste Management Facility. It will be submitted to the Environmental Protection Authority (EPA) for review later this year, and once approved; it will be issued for public comment in January 2012.

Following the environmental and planning approval process, EMRC Council will decide whether to proceed with the tender process. Acceptable tenderers will then be invited to tender for the preferred technology options and ownership options. The Tender process will be overseen by a Tender Evaluation Committee and an independent probity auditor.

Only one of the two technology options will be constructed at the RRF at Red Hill, and a final decision on the chosen technology will be made at the conclusion of the tender process in late 2013.

In May 2009, the EMRC advertised for Expressions of Interest (EOI) in providing technology options for the Resource Recovery Project. The purpose of this process was to inform EMRC Council about the different technologies to guide their decision making process. It would also enable EMRC to gather important information, including cost and environmental performance, to assist the EMRC to select a preferred site, ownership model and waste collection system for the RRF. The Expressions of Interest process was overseen by a Tender Evaluation Committee and an independent probity auditor.

Each submission was evaluated against a number of criteria set out in the EOI documents. The main focus was on their capability to successfully deliver a similar project.

The criteria included:

• Demonstrated maturity and successful performance of technology
• Respondents experience in successfully implementing similar projects
• 26 other environmental, technical, corporate, social and financial criteria

Tenderers were invited to submit expressions of interest for one or more of five technology options: mechanical biological treatment - anaerobic digestion, and/or Energy from Waste (EfW) - gasification, pyrolysis, combustion, plasma or combinations thereof (all thermal technologies).

The EMRC wanted to gain information about all of these technology options in considering what the preferred technology options were for the proposed facility at Red Hill Waste Management Facility. The initial list of technology options included other options such as aerobic composting which was subsequently excluded.
 

Thermal technologies can be defined as processes that use heat to convert municipal waste into energy and ash or, using controlled conditions, into energy rich fuels and ash or char. Combustion is an example of the former and gasification and pyrolysis, also known as thermal conversion technologies, are examples of the latter.

The energy rich fuels made during gasification and pyrolysis are intermediate products which offer the potential to make a range of chemicals and vehicle fuels or they can be converted to energy.

The EOI phase of the Resource Recovery Project was completed in July 2009. Seven of the nine submissions received were assessed as "acceptable tenderers" by the Tender Evaluation Committee.

 In July 2011, Council noted advice from SITA Environmental Solutions and WSN Environmental Solutions of their intention to withdraw from the tender process for the Resource Recovery Facility. The list of acceptable tenderers has now been amended.

The acceptable tenderers are:

• Energos AS;
• Evergreen Energy Corporation Pty Ltd;
• GRD Minproc Limited;
• Phoenix Energy Australia Pty Ltd (formerly Moltoni Energy Pty Ltd); and
• Transpacific Cleanaway Limited

 These five respondents to the EOI will be invited to submit a tender at a later stage in the project (2012) once the environmental approvals process is complete.
 

In parallel with the EOI process, the EMRC undertook community research from May to July 2009. The objective of the research was to take a snapshot of community views on possible site and technology options and provide this feedback to Council where it could be taken into account in their decision making process. The research involved community surveys and focus groups. There was also consultation with member Councils. Please click here for the results of the research.
 

In September 2009, the Tender Evaluation Committee reported outcomes of the tender process to the Resource Recovery Committee (RRC) which comprises senior staff and councillors from EMRC's six member Councils. The RRC made preliminary recommendations on preferred options. These recommendations formed the basis of consultation between the EMRC and the member Councils and the community. Final recommendations on the tender process were made by EMRC Council in May 2010.

At its meeting on 18 August 2011, Council resolved to reduce the technology options for the Resource Recovery Facility to anaerobic digestion and gasification, eliminating pyrolysis and combustion as possible options.
 

The bin collection systems evaluated have included:

• Current two bin system (rubbish and recycling bins)
• Three bin system [organics bin (food and green waste), recycling bin and residual waste bin]. For results on EMRC's trial of the organics bin, please click here.
• Single bin system (rubbish and recycling combined)
• A wet/dry bin system (wet bin for organics, dry bin for recyclables and other rubbish)

In May 2010, Council resolved that a third bin for household organic waste collection be considered in conjunction with anaerobic digestion technology, otherwise a two bin system is recommended for the thermal technology options.
 

All of the technology options being considered are in use in different countries, including some in Australia. Please view the document below (see 'Download documents' section) for an indication of where the technology options are currently being used.
