Energetic and economic viability of olive stone recovery as a renewable energy source: a Southern Italy case study
AbstractThe recovery of olive stones for biofuel is becoming increasingly widespread in olive milling plants. In this study we look at the economic and energetic benefits of using a de-stoner machine in a small-to-medium sized oil milling plant. The performance of the olive stone recovery system was evaluated over a full olive oil production season. The energetic viability of the de-stoner was assessed using a Life Cycle Assessment approach, and the break-even point was achieved when about 56 tons of olives had been processed, which is less than the annual production of the mill in question. Similarly, in economic terms, the machine covered its costs after about a quarter of its technical life.
