Biodegradability

Environmental protection plays an important part in a product‘s entire life cycle. Biodegradability is an important factor in this context and requires extensive studies, as early as in the chemicals‘ approval stage. Additional applications of biodegradability tests are testing of potential water pollution during storage and transport.

For the informed end consumer, environment-friendly product qualities are an important purchasing factor and a highlighted feature for manufacturers and retailers (e.g., environmental labelling such as the Blue Angel).

SGS INSTITUT FRESENIUS offers the entire spectrum of international standardized testing methods under GLP and other accredited conditions. The Competence Center BioServices provides competent analytical and problem solving services in all stages of product development, manufacture, and disposal.
