Actions

 

During the period between October 2003 and December 2006, that the implementation of the DIONYSOS Project took place, the following actions materialized:

Various alternative scenarios for the management of winery wastes were designed, tested and evaluated. These scenarios aimed at the effective and integrated treatment of the specific waste and simultaneously at the recovery of the polyphenols content.

The optimum management scenario was selected according to technoeconomic and environmental criteria.

Based on the selected scenario a test plant was designed and constructed at pilot scale.

The pilot plant operated during two successive wine producing periods. During this period continuous improvements of the pilot plant took place in order to achieve its optimum performance

The application of the developed technology led to the production of:

Enriched polyphenolic extract (1 Kg per 100 Kg of grape pomace)

Pure polyphenols (e.g. resveratrol)

The above products are suitable, in terms of chemical form and purity, to be used as raw material in various applications:

- production of medicines

- production of cosmetics

- production of food supplements etc.

Natural organic fertilizer (compost).
