PROJECT DESCRIPTION
BACKGROUND
The purpose of the project concerns the biological treatment of the liquid wastes of olive mills through the use of a biowheel, mixing of the liquid wastes with the extracted press cake from olives (solid waste of olives) and the production of organic fertilizers through the co-composting process. The final product should be free of toxic substances, should enrich the soil and should constitute a good quality fertilizers for plants in general. The project begins with the preparation of studies and designs regarding the technical specifications of the proposed installations. The particular needs of each olive oil mill are taken into consideration and a selection is made of sub-contractors and test fields. Following the selection, construction began on the units¿ sites and tests. Once it was completed, improvements were made on the operation of units. At this point, cultivation began using the produced fertilizers. Subsequently an evaluation was conducted on technical, environmental and economic aspects. The project ended by disseminating the results, during the entire project. It is hope that this project will lead to an optimal waste re-use method for the liquid wastes of olive mills.
