Objective
The olive oil extraction using the new two-phase decanters generates a material
constituted by a liquid-solid mixture called 'alpeorujo'. In some cases this by-
product is used for obtaining orujo-oil by extraction; in others, it is partially mixed
with compost and animal feeds, and in others it is simply considered as waste and
it is either discarded or destroyed or incinerated under more or less uncontrolled
conditions. The two-phases decanter has been fully developed during the last three
years. Its advantages over the three-phase system are that it produces a single
waste stream and requires less fresh water. The two phase system is currently
used by 25 % of the companies of olive oil extraction and the expectation is that
this percentage will continue to increase.
However, there are following problems with the two phase system which have not
been solved yet : Feasible treatments to validate alpeorujo and to reduce end-waste
are not well defined yet. A number of SMEs have to adapt their drying and
extraction systems for treating alpeorujo. The drying of alpeorujo is more costly
and difficult than it was originally predicted due to its high content of water, poly-
saccharides, and poly-phenols.
The objectives of this project are to define feasible alternatives for the validation
of alpeorujo. Several procedures will be investigated : balanced-protein enrichment
to produce animal feed; bioremediation and composting for plant and mushroom
cultivation; fluidized bed and spray drying; combustion/gasification for energy
recovery; and anaerobic digestion for the production of biogas.
The results will allow to develop industrial standards and methods for the treatment
of alpeorujo in an economical, feasible and environmentally sound approach.
Specific expected tangible impacts are : competitive products for the animal feed
market; plant fertilizers and mushroom cultivation media; new alternatives for
reducing energy costs and environment impacts; systems tools to assess costs and
impacts of alpeorujo treatment in industrial plants.
