![]() ![]() ![]() This process delivers energy to the micro-organisms. Although similar to combustion, this biochemical process is much longer, comprising several small bio-oxidation steps via long-chain alcohols and carboxylic acids, as well as shorter chain acids down to acetic acid and carbon dioxide. ![]() It is initiated and performed by the enzymes of micro-organisms such as algae and microfungi. It essentially measures the loss of oil and oil-soluble metabolites over 21 days in a nature-like aqueous environment.īefore presenting the new test method, an understanding of biodegradation may be useful.īiodegradation of organic material (natural or synthetic hydrocarbon compounds) is actually biochemical oxidation. Following criticism of the Coordinating European Council’s well-known biodegradability test (CEC-L-33-A-93) for its use of hazardous solvents, and with alternative tests not designed for testing lubricants, a technical development group (TDG-L-103) was formed to establish a replacement test method.Īfter 3½ years, a new biodegradability test procedure has been developed, thoroughly tested and approved. ![]()
