WRAP report on physical contaminants in PAS composts & digestates
Consistent methods of sampling and testing of physical contaminants in composts and digestates are essential for building confidence in their respective BSI PAS100:2011 and BSI PAS110:2014 specifications. This WRAP funded project investigated the current robustness of sampling and testing and, where necessary, provided recommendations for improvement. It also investigated the German approach to analysing film plastics in which their presence is quantified on an area basis, as well as a weight basis.
