VIC EPA to assess WtE proposal

The Victorian EPA is assessing a works approval application for a waste to energy facility in Dandenong South.

The proposed facility, to be operated by Great Southern Waste Technologies, seeks to utilise gasification technology to process 100,000 tonnes of municipal solid and commercial and industrial waste each year.

According to an EPA statement, if built, the facility will deliver approximately 7.9 mega watts of electricity to the grid.

“EPA will assess the proposal against all relevant environmental policies and guidelines and look at any potential environmental and human health impacts that could result from the proposed development, including, but not limited to, air emissions, odour, noise, greenhouse gas emissions, wastewater treatment and discharge and reuse of wastewater or residual ash,” the statement reads.

In its works approval application, Great Southern Waste Technologies states that the facility will use proven technology to recover energy and export it into the grid as base load power, available to both commercial and residential customers.

“Utilising this valuable resource through recovery of the energy offers a sustainable improvement to waste management services currently being provided in Dandenong South, whilst reducing the overall greenhouse gas emissions and the potential environmental impacts associated with landfilling,” the application reads.

Submissions are open until 8 January 2020.

Tyre pyrolysis and gasification report to inform industry

To inform the industry on the use of tyres in thermal processing plants, Tyre Stewardship Australia (TSA) has released a report into the effectiveness of both pyrolysis and gasification.

The Tyre Pyrolysis and Gasification Technologies – A brief Guide for Government and Industry report looks at the global history of operating plants and considers the economic and end-product market factors that are critical to the commercial viability of recycling technologies in the Australian market.

High temperature thermal processing can create oil, synthetic gas, carbon black and steel, while also providing a way of handling a waste stream that can have potential environmental or health problems if stockpiled.

TSA Market Development Manager Liam O’Keefe said the motivation of the guide was to provide the industry thought leadership on both emerging technologies as possible recycling solutions and to better inform government and businesses considering investment in such technologies.

“Obviously, TSA is interested in any technology that can sensitively recycle almost 100% of a waste tyre, but we must be aware of the prevailing market conditions, investment costs and competitive pressures that play a role in establishing the economic sustainability of such projects,” Mr O’Keefe said.

“We believe the guide, by providing a high level of consultation, analysis and technical and economic detail, will be an aid to decision making around proposed facilities.

“No one technology will meet the waste tyre environmental challenge on its own. The best result with such immense global resource recovery and management challenges usually comes from a combination of options, offering the flexibility to adjust to future conditions and developing market demands.”
