ENERGY RECOVERY AND SOLID ORGANIC WASTE MANAGEMENT USING DRY ANAEROBIC DIGESTION

Abstract

Anaerobic digestion has always been regarded as a feasible course decreasing carbon-based matter and improving Hydrogen and Methane as renewable energy sources from organic carbons, and has managed to the overall gasification of biodegradable organic wastes further more. Although misty anaerobic assimilation has been well developed, it is a challenge to adapt this type fermentation technology for carbon-based unwanted with excess of solid contents. In such condition, arid methane fermentation would be an appropriate approach. Arid methane fermentation is a ground-breaking anaerobic digestion method of recycling solid organic backwoods for energy retrieval and releasing nutrient-rich fertilizer without dilution of substrate. This technology helps in Waste controlling in a country like Nepal, where municipal wastes, hospital wastes, domestic wastes, farm wastes, and livestock manure are existed in abundance. Though the assembly of biogas over anaerobic absorption is not a new knowledge, anaerobic digestion procedures are frequently worked at well below their best performance due to numerous influences. The feasible and advantage of arid fermentation process for treating solid organic wastes are deliberated. While the optimization of environmental situations inside the digester such as temperature, pH, buffering capacity and fatty acid concentrations etc. are investigated with a least retention time in this paper.
