Introduction and procedure Comparing with biomass-derived lubricants, in many cases conventional lubricants turn out to have disadvantages for their environmental impact, especially where losses occur during regular operation (e.g. in chainsaws) or where a leakage leads to immediate emissions into the environment as for agricultural machinery. Bio lubricants are supposed to be environmentally friendly, among other things because of their fast biodegradability or the saving of fossil resources. But they can provoke also negative impacts on the environment, caused for example in part by the agricultural production of the raw material. This study gives an overview over the advantages and disadvantages of bio lubricants and offers a valuation of the results.
