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

on the ISO list of patent declarations received (see www.iso.org/patents).

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/

ISO 5424:2022(E)
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.
