Extremely high organic matter content
Olive mill waste are rich in potassium, nitrogen, phosphorous and magnesium. The organic matter content in olive wet cake is up to 92%, therefore its controlled recycling as amendment to agricultural soils and mainly to soils poor in organic matter, as Mediterranean soils are, has been proposed as a solution for OMP management.
Support of the Government
According to Italian environmental legislation,olive mill pomace and waste water have to undergo treatment before their release into the environment. A new regulation permits use of wet solid waste from the two-phase process as fertilizers on croplands. Such spreading on land must be known to the authorities and supported by a technical report.
Reducing disposal cost
More and more olive mills change extraction process from three phase pres process to two phase extraction. Therefore, most of olive mill residues and OMP is semi-liquid and semisolid, contrary to the tradition three-phase in which the solid and liquid residue. Due to high disposal of olive mill residue, to seek for an option that can reduce disposal cost is necessary and immediate. Compost OMP needs ordinary open space not evaporative ponds, which can help olive mills reduce related cost.
Simple and cheap alternative
Choosing OMP as organic fertilizer production raw materials, just buy compost windrow turner and learn related composting technology, you can begin your composting. It might be an economical option without other ponds construction and investment.
Realizing organic matter cycling
Due to using olive mill residue as raw materials and making compost, it can be used as fertilizer for olive orchards and crops. In this way, it can be regarding as ecological cycle.
