Improvements to biodiesel compositions, and methods for making those compositions more efficiently, are provided. Some variations of this invention provide processes for producing biodiesel and at least one C1-C4 alcohol, such as ethanol. Other variations provide certain biodiesel compositions containing C2+ alkyl esters. In some embodiments, biodiesel compositions are produced entirely from renewable resources. L'invention concerne des améliorations apportées à des compositions de biodiesel et des procédés destinés à produire ces compositions de manière plus efficace. Certaines variantes de la présente invention concernent des procédés de production d'un biodiesel et d'au moins un alcool en C1-C4, tel que l'éthanol. D'autres variantes concernent certaines compositions de biodiesel contenant des esters d'alkyle en C2+. Dans certains modes de réalisation, les compositions de biodiesel sont entièrement obtenues à partir de ressources renouvelables.
