DESIGN THE SURVEY TO SUIT THE SITUATION
• You need to decide:

• what should the sample size be?
• what you do to suit the site and waste stream?
CONSOLIDATION OF SORT AND WEIGH PROCEDURES
SEPARATION OF VISUAL AND SORT-AND-WEIGH METHODS
• The two methods are not alternatives that produce the same outcome. They suit different needs.
OTHER UPDATES
