Prerequisites and quality of compost for evaluating composting of packaging
This annex describes prerequisites for packaging, from use to collection, prerequisites of compost and composting plants for the biological treatment of organically recoverable packaging. These prerequisites should be considered in advance of the market release of packaging intended for entering the biowaste stream even if they are not part of the analytical testing procedure.
D.1 Prerequisites for composting of packaging
D.1.1 Composition
All of the packaging materials should be biodegradable and the packaging or the packaging components in the final shape should be compostable, meeting the criteria in this standard.
NOTE The fulfillment of the quality criteria for compost input material alone will not necessary lead into production of quality compost.
D.1.2 Products and their residues
If in any case the product filled into a compostable packaging could remain in parts or as whole in the packaging after the normal use, the products should by themselves be compostable and neither toxic nor hazardous.
If the shape of the packaging is a hollow body it should not be closed tightly and should preferably be empty.
D.1.3 Grinding/shredding
The shredding of used packaging with machinery and procedures, commonly used in composting plants, shall not be disturbed and should lead to particle sizes of less than 10 cm in the longest dimension, suitable for the composting process.
