Olive pomace plantsprocess olive paste, a waste product of olive mills which produces crude olivekernel oil and olive kernel wood. Olive kernel wood has very good burningcharacteristics, high heat content, low cost and it is used as a renewablesolid fuel replacing liquid fuel and heating oil. Part of the produced olivekernel wood is consumed inside the factory for heat generation and the rest issold to heat consumers. It has been estimated that a typical olive pomace plantlocated in Crete, Greece consumes 42.86% of the produced olive kernel wood forits own heat generation, while the remaining 57.14% is sold to various heatconsumers. 99.1% of the energy used in these plants is consumed for heating andthe rest, 0.9%, for lighting and the operation of various electric devices.Olive pomace plants utilize a renewable solid fuel, which is carbon neutral,for the production of thermal energy. Therefore their CO2 emissionsregarding energy utilization are due to electricity use. Installation of solar-PVpanels in the plant could generate annually all the electricity needed for itsoperation. The current legal framework in Greece through net-metering allowsthe offsetting of grid electricity consumed in factories with PV electricity.The required capital cost of a solar-PV system installed in a typical olivepomace plant located in Crete, Greece in order to offset the grid electricityconsumed annually has been estimated at 185,832€, the payback period of 5.33years and the net present value at 555,671€. Since the plant could utilize onlysolid biomass for heat generation and could offset the grid electricityconsumption with solar electricity, its total CO2 emissions due toenergy use would be zero contributing positively to climate stabilization.
