WHAT WE DO

What is waste to energy (WtE) and why is it important?

WtE is described as a ‘higher order’ waste management
option than disposal to landfill. It addresses the
economic issue of waste being a lost resource and
avoids the potential adverse environmental outcomes
that may arise from landfilling waste. These include
leachate* management and groundwater contamination,
which can require ongoing management well beyond
the operational life of landfill sites.

In Australia over 21 million tonnes of waste is sent to landfill each year, losing the embodied energy* of the waste while increasing greenhouse gas emissions through methane and carbon dioxide generation, along with a range of other greenhouse gases.

WtE facilities have the potential to reduce the waste sent to landfill by up to 80 per cent (or about 95 per cent where ash products are diverted from landfill for reuse). This minimises dependency on new and expanded landfills and ensures existing landfill capacity is retained for unrecoverable materials in future.

WtE works alongside recycling and resource recovery programs, delivering improved environmental, economic and social outcomes for residual waste management.

GSWT is excited about our new facility because WtE is an essential piece of the waste management puzzle that has been missing for municipal councils and businesses in Melbourne.

A variety of WtE plants across Europe operated by Energos, the technology company with which GSWT has formed an alliance.

We are proud to take our lead from northern Europe where advanced technological solutions like this have been in place for generations. Over 450 WtE facilities are currently operating throughout Europe. These include:
