Olive Residue - Solid Biomass for Heat and Power Plants

The Exhausted Olive Cake is a dry material (solid biofuel) composedof ground olive stones and pulp.

This material may come either from the pomace paste itself after the drying phase, or from the previous centrifugation before the physical extraction phase. Exhausted olive cake differs from crude olive cake mainly by lower oil content and a smaller water content because it has been dehydrated during the extraction process.

Due to the low ash content of these stones and the type of combustion, this material is very efficient, in terms of bio heat production, cost and environmental impact (zero net contribution to the greenhouse effect, drying gases comply with European Legislation for gaseous pollutants). By exploiting the calorific potential of the exhausted olive cake it is also possible to generate electrical energy.

The traditional use of exhausted olive cake is as fuel in drying ovens or biomass boilers because of its thermal capacity. A biomass boiler with a fully automated feeding system can be used by a wide range of heat plants and agricultural businesses. The annual cost of biofuel for heat production is much lower than the cost of heat production that is based on the use of crude oil. The exhausted olive cake which has also been dehydrated during the extraction process could be stored for over a year.

Some identical specifications of the exhausted olive cake are the following:

Net Calorific Value: min. *6.**0 MJ/kg
Moisture: max *6%
Ash content : max. 4.1%
Oil: max. 1.3%
Sulphur: max. 0.1%
