    Characterization Qualitative Of Soel For A Valorization Best Of The Biomass Produced
    (University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Saad, I.
    The main objective of this study was to qualitatively characterize biomass of Solanum elaeagnifolium Cav. (or SOEL) to highlight the essential alternatives its valorization. At first, we studied the potential of composting biomass of this plant. The physico-chemical characterization of biomass silverleaf nightshade has detected a wealth in organic carbon, which highlighted the potential value of this plant in the Co-composting with other biodegradable waste. In a second step, we assessed the possibility to develop this plant in the area of treatment in textile effluents by biosorption of dyes on fibers from the biomass of this plant, especially after the discovery of high levels of cellulose in its different organs.

    Effect Of Heat Treatment On The Germination Of Seeds Soel
    (University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Saad, I.
    The object of this work was to study the effect of thermal treatments (in the oven and in the compost) on the seed germination SOEL. The laboratory evaluation on the treatment in the oven berries at two temperatures (50°C and 60°C) for three exposure time ( one day, two days and three days) gave a germination rate zero for 60°C for an exposure time of one day. The spatio-temporal thermal monitoring of forestry compost windrow which was introduced to deal with berries SOEL showed a substantially homogeneous distribution of the temperature rising to 60°C and even longer swath stretching and used for a time period of 5 consecutive days. The germination rate was zero for all fruit seeds treated before the first reversal fact, regardless of the depth and location of the windrow considered that the berries were introduced. Thus, composting can be a solution to prevent the spread of SOEL by seed.

    Valorizations Environmental, Energy And Agronomic Of Biomethanisation Industrial Of The Avicolous Biomass
    (University of Eloued جامعة الوادي, 2015-01-01) M’sadak, Y.; Ben M’barek, A.
    This work consists in studying the anaerobie fermentation of the avicolous droppings on the level a digester pilot industrial. It was interested towards substitution partial of Forestry Compost (FC), produces locally in one seedbed except ground, by the avicolous methacompost refined in its two states, namely at the exit of decanter (AMCA) and at the exit of digester (AMCA') according one rate of 20%. The synthesis of the principal results is: the best assessments of depollution are obtained on the level of the mud tank as well concerning SM and DBO5; the incorporation of the avicolous methacompost with FC has a remarkable positive effect on germination, and consequently, on the growth of the seedlings of Acacia cyanophylla, in terms of height and of diameter; the best results of growth in height and diameter correspond to the mixture 80% FC + 20% AMCA'.
