    ABSTRACT: Batch digestion experiments were conducted to determine the effects of inoculums/substrate ratio of three different ratios (ISRs) 0.3, 0.5 and 1. The substrate chosen in this study was slaughterhouse waste from Adrar city (south west of Algeria). The inoculation was made by sludge issued from wastewater treatment plant. During this study, several parameters of anaerobic digestion were measured, such as pH, VFA, AT and volume of the produced biogas. pH variation and VFA/TA values have shown high stability of anaerobic digestion process.

    ABSTRACT: This study presents a feasibility analysis of grid connected photovoltaic system introduction to a dairy farm located in Mitidja plain (north Algeria) to promote farming sustainably. Real load data from ITELV BabaAli dairy farm of 26 dairy cows is used. The farm electricity consumption is mainly for milk production equipments and the cattle housing. The system is optimized by HOMER software using Mitidja global irradiation and the farm load profile. The electricity tariffs and the photovoltaic system components are modelled according to the Algerian market. Viability was determined according to the net present cost, electricity power flow and CO2 saving potential. According to the optimization criteria, two optimal systems that meet the dairy farm load of 23.6kWh/day have been found. The first optimized system offers a renewable electricity with an optimal cost of 9.7c$/kWh, and the second optimized system has a net annualized surplus electricity of 26.45MWh and a greenhouse gases mitigation of 554 tons over the system lifetime.

    ABSTRACT: At the dawn of the twenty-first century, one of the major problems of mankind is to combine the energy, the respect for environment. A problem of sustainable development has been clearly demonstrated in the Earth Summit in RIO (2012). Among the major battles to be fought in this century for the survival of the planet is to include energy efficiency as an international political priority, reduce emissions of greenhouse gases. Renewable energy, inexhaustible, clean, are needed in these conditions as a priority.
