Abstract

The modern society is, nowadays, facing two major problems: the energy sources depletion and the degradation of the ecologic system because of wastes rejection. The energetic valorization of wastes contributes on the resolution of both problems. In the present work, a feasibility study of an industrial pilot scale installation for the production of biodiesel from waste grease traps is lead. The installation is meant to transform 1000 tons of fat trap grease per year to biodiesel by transesterification. The daily production of the unit reaches 3200 l of biodiesel. All necessary equipments were sized following process engineering design and based on lab scale optimization experiments. Installation energy balance was also realized and it showed that the energy required for the installation functioning does not exceed 3.5% of the heating value of produced biodiesel.
