Mapping organic waste in Sydney to advance anaerobic co-digestion for energy generation and GHG reduction

Purpose of project

This project will bring together key stakeholders in the typically siloed waste, wastewater and energy sectors to quantify and geospatially map the multiple layers of UOW in Sydney and assess its bioenergy potential. The project is expected to demonstrate the potential of AD as a climate change solution that generates bioenergy, cuts waste GHG emissions, recovers nutrients and potentially saves millions of dollars through optimising existing and planned AD infrastructure.

Impact of project

Using the best available data for UOW catchment areas around two to three specific Sydney Water WWTPs, this research will identify in a geospatial format the estimated mass of various streams of UOW for both the residential and non-residential sectors (e.g. garden organics, food waste, used cooking oil and fats, oils and grease), depending on data availability. This information will enable the project partners involved to assess which streams are viable in terms of the quantity, quality and bioenergy potential to target for potential collection for co-digestion treatment at the specified WWTPs (or other more appropriate potential treatment).
