Sustainable Energy and waste management are among the focus for researchers and government activities
Sustainable Energy and waste management are among the focus for researchers and government activities. The anaerobic digester is a device used to produce energy, methane gas, from organic wastes. In this paper, an evaluation of Biogas Generation from Food in effluent waste in Student Cafeteria of Samara University presented. An observation used to identify the waste used for this research at initial survey. Four different distinguishable waste categories were identified for sample taking. Point one is a place where leftover food is temporarily stored and locals take for animal feed. Point two is from first manholes where effluent food contains cooked oils. The third category is oil-free waste points. The fourth point contains stored water which is separated by overflow process through the manhole of the food waste. Since changes in pH, temperature and C/N ratio are major factors affecting Anaerobic digestion, these factors are determined experimentally. The solid waste sample was taken from point two and point three to analysis their moisture content, organic matter, total nitrogen and C/N. The C/N ratio of waste is much greater than the allowable range for both waste samples. An addition of nitrogen contained material is necessary to improve the ratio of C/N before feeding this waste to the biogas digester. Furthermore, the quality of wastewater at point four was also analyzed to determine a possibility of using it for irrigation purposes for our campus.
