Public debate around the
topic of microplastics is very controversial and extremely complex, as there is
no internationally binding definition for the term “microplastics”. At
Beiersdorf, we understand microplastics to be solid, water-insoluble plastic particles
that are five-millimeters or smaller and not biodegradable. In doing so, we
rely on the substantiated
definition of the UNEP, the United Nations
Environment Programme, thereby adhering to broadly shared scientific opinion.
It is
problematic if such small plastic particles end up in the environment because
they do not easily biodegrade and thus burden ecosystems. According to current
research, microplastics detected in the environment come from a diverse range
of sources: The vast majority of small plastic particles originate from larger
pieces of plastic that have not been correctly disposed of and, due to solar
radiation for example, have decomposed over time.
Other
relevant sources of microplastics are particles that result from tires, paint
or artificial grass abrasion, for example, as well as fibers from synthetic
clothing that come loose in the wash. Smaller plastic particles from industry,
such as pellets, and some ingredients in household cleaning products and
cosmetics, can also be considered microplastics.
