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.
