ISO 17088:2008 specifies procedures and requirements for the identification and labelling of plastics, and products made from plastics, that are suitable for recovery through aerobic composting. The four following aspects are addressed:
- biodegradation;
- disintegration during composting;
- negative effects on the composting process and facility;
- negative effects on the quality of the resulting compost, including the presence of high levels of regulated metals and other harmful components.
This specification is intended to establish the requirements for the labelling of plastic products and materials, including packaging made from plastics, as compostable or compostable in municipal and industrial composting facilities or biodegradable during composting (for the purposes of this International Standard, these three expressions are considered to be equivalent). The labelling will, in addition, have to conform to any international, regional, national or local regulations (e.g. European Directive 94/62/EC).
