WHAT IS A SWAP?
• Tool developed by MfE
• To collect reliable and consistent waste data

WHY IS THE SWAP BEING REVIEWED?
• Introduction of the WMA
• Keeping it relevant
• Ease & Cost
• Good information Sound decisions

WHAT ARE THE LEGISLATIVE DRIVERS?
• Waste Minimisation Act
• Climate Change Response Act
Emission Trading Scheme (ETS)
• Legislation & 2002 SWAP
• Likely to amend legislation
• UEF’s and the EPA

HOW DID WE DECIDE THE SCOPE?
• Stakeholder feedback
• Range of issues identified
• Constraints

WHERE TO FROM HERE?
• We’d like your feedback

WHAT HAS CHANGED?
![Page 10: SOLID WASTE ANALYSIS PROTOCOL - AN UPDATE...1992 Waste Analysis Protocol (WAP) 2002 Solid Waste Analysis Protocol (SWAP) 2012 SWAP Update WHY IS THE SWAP BEING REVIEWED? •Introduction](https://reader035.fdocuments.us/reader035/viewer/2022071109/5fe4a08f3b7fa94233413bc2/html5/thumbnails/10.jpg)
THE 2012 UPDATE
• More emphasis on good survey design
• Still provides the standard survey methodologies
• Provides clear distinction between visual and sort-and-weigh methods
• More guidance on calculating the precision achieved

DESIGN THE SURVEY TO SUIT THE SITUATION
• Scalable methodologies
• Balancing precision and practicability
• Good survey design
• SWAP data used for a wide variety of applications

DESIGN THE SURVEY TO SUIT THE SITUATION
• You need to decide:
• what you want the data for?
• when and how often you need to survey?
• what should the sample size be?
• what you do to suit the site and waste stream?

CONSOLIDATION OF SORT AND WEIGH PROCEDURES
![Page 14: SOLID WASTE ANALYSIS PROTOCOL - AN UPDATE...1992 Waste Analysis Protocol (WAP) 2002 Solid Waste Analysis Protocol (SWAP) 2012 SWAP Update WHY IS THE SWAP BEING REVIEWED? •Introduction](https://reader035.fdocuments.us/reader035/viewer/2022071109/5fe4a08f3b7fa94233413bc2/html5/thumbnails/14.jpg)
SEPARATION OF VISUAL AND SORT-AND-WEIGH METHODS
• The two methods are not alternatives that produce the same outcome. They suit different needs.
