We are trying several things although the volume is, as yet, insufficient
for any commercial use. This will change over the next few years of course
and we take note of the experience of our friends who have been at it much
longer. Interestingly, in Australia in the 1950's, the waste was used to
make briquettes (Bertini). We probably should stop calling it "waste" as I
am sure that there will be absolutely none wasted!
Some of the uses currently being trialled are:-

*Poultry producer is experimenting with the waste as a food extender.
*Local grower is mulching effectively with product
*Worm farmer using waste to effectively breed up
*Sheep love the stuff straight out of the machine
*Partially air drying product and then using it to make olive bricks (via a
mud-brick making machine) - build your own peace house.
*Total drying and then compressed into logs for burning
*Mixing with other fertilisers to extend product

A posting some time back revealed that our American friends use the pits (as
they stuff a lot of olives) mixed with tarmac to make road surfaces.
Perhaps some one could advise use of the longevity of such roads?

The following waste analysis may be of interest to people:-

Total Nitrogen 1.18%
Total Phosphorus 0.14%
T. Potassium 2.03%
T. Sulphur 0.11%
T. Calcium 0.18%
T. Magnesium 0.09%
T. Sodium 0.02%
T. Manganese 110ppm
T. Zinc 8ppm
T. Copper 4.2ppm
T. Cobalt 0.26ppm
T. Boron 26.4ppm
T. Molybdenum 0.16ppm
T. Cadmium 0.39ppm
T. Lead 10.01ppm
T. Mercury <0.001ppm
T. Organic Carbon 54%
pH 4.7
Moisture content 23.8%

Interesting to note the relatively high levels of Manganese and Boron
present in the waste.
