Definitions

• the invention deals with the way of disposal of waste from olive oil production.
• Another method is used e.g. for the disposal of sludges resulting from wine clarification, so called blue sludges.
• This method is based on calcination of the sludges at high temperatures, i.e. in principle on their pyrolitic decomposition.
• Advantage is taken of the fact that the sludge contains certain amount of bentonite and the final product can be used as an additional raw material in the field of brickmaking, ceramics, cement and other industries. Neither this way of disposal is suitable for the purpose of this invention, since it assumes the proximity of a high temperature source and the presence of e.g. ferrocyanides, so that the process of calcination can occur.
• Liquid phase of the waste whose density is between 800 to 1000 kg/m 3 , is continuously mixed, at a ratio of up to 300 kg of natural bentonite, to 1 m 3 of the liwuid phase of waste. After that a solid phase of waste is admixed and the mixture is inoculated and subject to forced aeration.
• Waste from olive oil production was used containing 28.6 % (by weight) of olive press cake, 17.4 % (by weight) of olive sap after the oil separation - so called marga and 54 % (by weight) of vegetable waste.
• Marga as the liqiud phase of waste with the density of 970 kg/ra 3 , was adjusted via mixing with natural bentonite, coming from the deposit Obrnice, at a ratio of 200 kg of bentonite to 1 m 3 of marga. The mixture was further mixed up with a solid phase, i.e. press cakes and with vegetable vaste while inoculation material was being added. Inoculation material was obtained as follows: 25 kg of the upper soil from the immediate vicinity of olive-trees was taken away and well mixed with 55 litres of untreated fresh-water water. After the sedimentation of insoluble parts the water portion was drawn off and immediately used.
• the adjusted compost charge its temperature of 31 °C, was charged into the bioreactor equipped with a controlled aeration regime and measurement of carbon dioxide concentration on the bioreactor off-gas.
• Appearance of the product shows unambiguously that the quality inter-reaction of original raw materials took place. Neither during the fermentation not after its completion the decomposition processes occurred which commonly accompany putrefaction of olive vaste with the release of undesirable and smelly compounds.
