The sign “100% Biodegradable Product”, describes products from the PCC Group offer that are completely biologically decomposed under aerobic conditions during 28 days (applies to biodegradation of surfactants measured by specific methods). Biodegradability is the ability of materials to decay by biological activity and in particular by the actions of microorganisms and abiotic components such as oxygen, UV or temperature. The process involves the decay of more complicated structures into less complex substances that eventually become an element of soil, aquatic environment or Earth’s atmosphere. Biodegradation is a very common process. It runs in all biocoenoses. It closes the biogeochemical cycles of most of chemical elements by bringing compounds to forms digestible by plants. As long as the biodegradation of naturally occurring compounds proceeds very quickly, the decomposition of man-made artificial substances can last up to several thousand years.
