V\u00fdroba biodieselu prob\u00edh\u00e1 procesem zvan\u00fdm transesterifikace. Tento proces zahrnuje reakci rostlinn\u00e9ho oleje nebo \u017eivo\u010di\u0161n\u00e9ho tuku (triglycerid\u016f) s alkoholem (obvykle methanolem), za p\u0159\u00edtomnosti katalyz\u00e1toru (obvykle hydroxidu sodn\u00e9ho nebo draseln\u00e9ho). V\u00fdsledkem je sm\u011bs methylester\u016f mastn\u00fdch kyselin (biodiesel) a glycerolu (vedlej\u0161\u00ed produkt).
