Conventional method. Most biodiesel is made in batches by mixing vegetable oil with methanol and a catalyst at elevated temperatures, letting the mixture settle, separating the process outputs into biodiesel, glycerin and “soap,” washing the biodiesel with an acid/water solution, and finally removing the water from the cleaned biodiesel. The entire process typically takes between 90 minutes to more than 24 hours.


Kreido BioFuels’ STT® technology-based method. Kreido’s biodiesel production technology is a continuous process that operates at low temperatures, takes less than one second to complete the transesterification reaction, and produces no water discharge. Compared to conventional processors, STT®-based biodiesel production units take up less space, cost half as much to build, can be built in a fraction of the time, are safer to operate, are better for the environment, and have lower operational costs.
