Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

Introduction
Plastic drinking straws are used worldwide for many years. This caused several environmental
problems, such as terrestrial pollution, contamination of soil and water/marine environment pollution.
These pose a severe risk to ecosystems, biodiversity and human health. Recently, many countries,
regions and cities have enacted legislation to ban or severely reduce the use of plastic drinking straws
to help tackle these issues.
This document does not aim to bypass this legislation, but aims to specifically address the following
aspects where plastic drinking straws suitable for industrial composting can be used:
a) offering methods for testing compostability, followed by demonstrating the impact of industrial
compostable drinking straws on the ecological environment;
b) providing a reference for the evaluation of industrial compostable plastic straws.
Development of this document is expected to effectively improve the quality management of industrial
compostable drinking straws in countries, regions, and cities where industrial composting is available.
