Introduction
The need for harmonized terms and definitions in the field of plastics relating to environmental aspects
is growing. This document intends to give a common set of terms and definitions and thus strives to
facilitate the communication and development of standards in this area.
The term “bioplastic” is not defined in this text, since EN 17228 states the following:
The terms “biopolymers” and “bioplastics” are commonly used to identify polymers and plastics that are
either bio-based, biodegradable, or feature both properties. While these definitions are quite widespread
and used by industry, it is recognized that they are susceptible to misunderstanding and thus
inappropriate for standardization purposes.
The terms oxo-degradable and oxo-biodegradable are generally used to indicate plastic products made
of conventional plastics (mostly polyolefins) supplemented in the transformation phase with catalysts
that accelerate oxidation of the polymer. There are no European Standards that clarify how the potential
of oxo-biodegradation can be measured and classified. However, the terms “oxo-degradable” and “oxo-
biodegradable” have been widely used, sometimes arousing controversy. The use for market purposes,
the lack of international standards, and the disputes raised over the marketing of these products are the
reasons for not defining the terms in this document, pending the elaboration of specific standards. It has
to be mentioned that the global market of “oxo-biodegradable” materials is deeply fragmented where, for
example, countries in the EU have banned these materials, while in countries such as the UEA, Pakistan,
Iran, Morocco, Yemen and DR Congo it is forbidden to use certain products like bags and plastic packaging
if they are not oxo-biodegradable.
NOTE A definition of oxo-degradable plastic is present in DIRECTIVE (EU) 2019/904, Art. 3, 3.
General terms have the addition “of plastics”, e.g. “recycling of plastics” in this document for clarification.
However, in practice they are often used without this addition.
1 Scope
This document specifies terms and definitions in the field of plastics related to environmental aspects
and provides a common vocabulary for:
— bio-based plastics;
— biodegradability;
— carbon and environmental footprint;
— circular economy;
— design;
— plastics in natural environments;
— reuse and recycling;
— waste management.
This document aims to provide a comprehensive glossary which uses the applicable definitions providing
when appropriate additional notes to make these definitions understandable without reference to other
documents. Definitions are as far as possible adopted from existing standards but when the original
intention or definition is unclear additional context or definitions are provided.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.4
additives
substances which are used to process plastics or to modify end use properties of plastics
Note 1 to entry: Substances are normally included in carrier matrix.
Note 2 to entry: Impact modifiers are rubbery type of additives added to plastics to improve toughness by absorbing
or dissipating the energy of impact.
Note 3 to entry: Rheology modifiers, also referred to as thickeners are additives that make a melt to become flowable
and easily poured when a force is applied.
Note 4 to entry: Plasticizers are additives that are mixed with polymers to make them softer and more flexible.
3.5
ageing
time-dependent irreversible chemical and physical processes in a plastic material under the influence of
one or more environmental factors leading to undesirable change in properties
EXAMPLES Extraction and evaporation.

be visible in the final form
