The Assessment Methodology provides comprehensive guidance for the social, technical, environmental and cost assessment of waste systems. Consistent with the assessment methodology, the streamlined assessment tool uses best available data and approaches to assist with streamlining the assessment process and establishing a relative ranking of available solutions.
The dual approach recognises the limitations on the decision making framework in terms of data availability. While there are advantages from linking to existing data and relevant studies and assessing these in the context of the assessment methodology, issues associated with data quality mean that the outcomes should be viewed as best available at a point in time. As data quality improves a more complete picture of technologies and systems will become available. The framework provides for the incorporation of new information as it becomes available and for changing conditions. As such, the emphasis for this initial stage of framework development is to establish a framework methodology and to capture work to date in the streamlined assessment tool.
