Due to an increased willingness especially of the industialized countries to preserve a healthy living environment, and due to the foreseeable depletion of exploitable fossile fuel resources, the use of alternative energie sources is becoming increasingly interesting to the general public. Next to solar energy, wind power and the controversially discussed nuclear energy, the use of renewable raw materials is gaining in importance. Especially renewable energy sources have a reputation of being environmentally friendly and virtually inexhaustible.
Rapeseed methyl ester, which is produced from vegetable oil through the simple chemical process of transesterification, is one of these renewable raw materials. It is often also called biodiesel, or RME for short.
Using current technical literature as basis for argumentation, the study demonstrates the advantages and disadvantages of the use of rapeseed methyl ester (RME, biodiesel) in comparison to conventional diesel fuel. Special attention was paid to economic and ecological effects as well as special technological features.
