How To Use Pomace



Many farmers have their own mill and personally process their olives. At the end of pressing an inevitable problem arises : how to get rid of the pomace (sansa). An Australian olive grower, Mr. Peter Caird, suggested some useful solutions.
I quote from one of his correspondence :
".... we have land located about 30kms from our factory in central Victoria (Australia) in order to let nature do the drying work for us.
Beds will be made using sleepers as the form work with each able to take about 5 tonne of pomace (wet). A bobcat will scurry around spreading the stuff and, come the Oz summer, we should have about 2.5-3.5 tonne of dry weight pomace ready for any number of applications."

  A mud brick manufacturer has already tested the material in a mix with clay. It makes a delightful brick, structurally sound, but lighter than normal.
A house of peace on the way!
Tests are continuing.

Compressing the dry pomace (or even wet with some modifications) to about 12 tonne pressure in a cylinder makes a perfectly usable "log" of firewood. It will probably need a years aging if wet pomace is used. Most likely everyone already knows that the pomace fuel burns quite intensely and almost without ash. Truly an environmentally friendly fuel that has another sensory benefit in that it gives off a delightful aromatic scent.

  I was informed quite recently that in the States they have quite a novel use for the pits of the olives. These are produced by the 100's of tonnes over there of course. They are mixed with bitumen and then used as tarmac for roads etc. "

Scientists Use Olive Industry Waste

The waste obtained from olive during the oil extraction process can be used to eliminate heavy metals from sewage or waste waters of productive activities. Olive pits, pomace and remains (from olive tree pruning) my olive treepresent an outstanding capacity to retain the lead present in this water, which confirms their capacity as biosorbents for their application in the depuration of effluents on an industrial scale.This is one of the main conclusions of the doctoral thesis “Characterization and application of residual biomass for the elimination of heavy metals” carried out by Ing. María de los Ángeles Martín Lara in the department of Chemical Engineering of the University of Granada.
