BrunnerWorkshop Vienna, 27 th -29 th, June 2001 Procedures to determine waste composition A: establish one uniform data set for all waste compo- sitions by all available means (  group process) B: measure/assess individual composition data for the three case studies (  analytical process) C: set priorities - waste mass flows[kg/c.y] - waste composition by elements[g/kg] - waste composition by goods[g/kg] - other (geometry etc.)
