At present, edible vegetable oils are most often used feedstocks for industrial biodiesel production. In this paper, the various non-edible oils and usually used processes for biodiesel production are analyzed from the ecological and economic aspects. The aim of the paper is to present the possibilities for improving the biodiesel synthesis by employing the heterogeneous catalysts, the novel catalysts obtained from waste materials and continuous process development, especially taking into account their impact on the environment. Key words:alcoholysis, biodiesel, non-edible oils.
