Abstract

Posidonia Oceanica is an endemic sea plant of the Mediterranean, which spans into great under seawater acres (25000 km2-5000 km2) and contributes to the oxygenation of sea water, the protection of the fauna and the prediction of any beach corrosion. Commencing from September- October, leaves and roots are extracted from the sea water plant and reach Cypriot beaches as well as other Mediterranean areas. The dry residues of this specific plant is a representative of large environmental, economical and social issues as well as many health problems in all Mediterranean beaches, as it causes great inconvenience for swimmers, but also the high cost of transportation and collection to reach the Board of Health. For this reason, it is very vital for differences in managerial methods of biomass to be examined and to find ways of conversion as a value added product, in this way inviting it to become more economically accepted. Managerial methods of P.Oceanica vary, since through the bibliography, there were various managerial approaches. For example, due to the fact of the sea water plant, a physics, chemistry and visual analysis was attempted, so that alternative solutions will be suggested, for the use and the application in agriculture as a means of the improvement of the land and their use as a source of energy. Additionally, excellent methods of management of this specific spermatophyte, is the production of bio fuels and the export of a widely adsorbent material that of the operative coal. Due to the big quantities which are brought to surface every year in Cypriot beaches, it was considered necessary to undertake a research in order to manage these residues. The present study, focused on the water capacity, the humidity of the residue after the drying out at 105νC, as well as the combustion of these, with activated sludge, deionized water, viomes of micro-organisms Chrysosporium Phanerochaete and only Chrysosporium Phanerochaete. The combustion with micro-organism was held into two containers, where one was placed at an incubator at 32νC and the other in a cupboard. The included humidity 0.308g P.Oceanica found to be at the same level of 79.05%, the water capacity could not be specified, but the results of combustion were not as expected, since the residue were not composted. Moreover, the samples of the residue were studied to identify any ashes to be equal as to 74.09%. The export of the substance called alginate was not successful due to P.Oceanica. Furthermore, the organic charcoal was studied within the oxidation of the samples with dual colouring of potassium alongside with the reduction of the pH stabilization and the electrical conductivity of the liquid solvent which was caused after the continuous washing with deionized water. The organic charcoal was not calculated due to the very dark colour which emerged after the residue oxidation.
