The basic idea of the building block is the transesterification of cooking oil under basic catalysis. Using this method shows that using simple materials, vegetable oil can be used as the base of biodiesel production.
The implementation of the building block requires a laboratory or room that has minimal infrastructure (Water and electricity hookups, sink, metal stand).
Upon successful completion of the building block the separated main components fatty acid methyl ester FAME and glycerin can be bottled.
Accompanying materials for the building block are available in both German and English language in the form of standard operation procedures, a theoretical component on biodiesel and a checklist for execution.
Aha-effect for students
Transesterification: From an oil two non-mixable components of similar volumes are formed (begging the question “Where to put and what to do with so much glycerin?”)
