Energy is a vital commodity. As the fossil fuel resources are limited and their demand is high, the energy gap can be met with the energy generation from renewable resources. Bio-energy generated from diversified sources provides local and emerging opportunities to reduce the over dependence on fossil fuels. Renewable energy from biomass is one of the most efficient and effective options among various other alternative sources of energy currently available. The anaerobic digestion of biomass requires less capital investment and per unit production cost as compared to other renewable energy sources such as hydro, solar and wind. Further, renewable energy from biomass is available as a domestic resource in the rural areas, which is not subject to world price fluctuations or the supply uncertainties as of imported and conventional fuels. Keeping in view the importance of biomass conversion into biogas, the book reports a methodology for maximising the biogas yield from the anaerobic digestion of organic wastes.
Assessment of potential drivers and barriers in biogas technology adoption as an alternative energy sources has recently become crucial and attractive due to the increasing demand for energy, the limited resource for buying fossil fuel and the environmental concerns. The Ethiopian domestic energy sector relies on a limited range of energy resources with a highest share being biomass that has brought substantial impact on the environment. Although Ethiopia is known by its large livestock resource potential, the level of manure resource utilization in this regard is very low. Overall, over 95 %of the domestic energy needs are met from biomass- based fuels thereby contributing to deforestation, loss of soil nutrients, and organic matter. However, so far, very limited studies were conducted in the area of rural energy in Ethiopia, specifically limited study has been conducted concerning the impacts, drivers and barriers of biogas technology on rural households. However, they did not asses the economic impact, and driving and constraining factors of the technology. Therefore, there is information gap on the benefit of biogas, its drivers and barriers on the study area.
Rwanda has been struggling to solve the energy issues consequent increase of biomass energy use for cooking that causes negative impacts on the health, the environment and the economy. Distinct financial and nonfinancial policies have been implemented to incentivize the use of renewable energy for cooking especially biogas energy with the purpose of giving alternative clean and sustainable energy supplies to all Rwandans, yet, penetration rate has remained extremely low. This paper investigated consumers' willingness to pay for domestic biogas digester technology as a substitute to traditional biomass energy for cooking in rural areas using conjoint analysis and discrete choice models. Estimation results show that consumers' preference to adopt domestic biogas digester technology increases with a sizeable biogas digester, with a low cost for biogas digester, with an increase in household income, with substantial guarantee period, and when the service provider is the private suppliers.
In today s energy demanding lifestyle, it is clear that there is a gap both now and in the future between energy needs for economic development and the ability of both the traditional and the conventional modern energy sectors to meet up with this need. It is therefore very expedient to explore and exploit new sources of energy, which are both renewable and eco-friendly. Renewable sources of energy contribute to sustainable development in diverse ways.Research in the field of bio-energy production reveals that organic waste generated from farms as well as municipal and domestic waste can be used as good sources of biogas.This book reveals the optimal conditions that give enhanced gas yield. Measurable physical quantities derived from our experimental data agreed with a Monod type kinetic equation. This book will therefore serve as a guide to biogas plant operators
In the modern energy-demanding lifestyle there is an overwhelming need for exploring sources of energy which are renewable and eco-friendly. Bioconversion of biowaste streams for energy production is an increasingly promising option. Through the biogas value chain, bioconversion presents a very attractive route to valorise various biowaste and enables communities to meet their energy needs, conserve resources and protect the environment. However there are challenges in sustainable implementation of biogas technology. The book has therefore reviewed the biogas value chain from a critical sustainability perspective. It has also covered a detailed case study of the potential of biogas production from biowaste in Kenya and how it influences environmental sustainability. The evaluation of biowaste energy potential and the development of a simple yet effective methodology to assess its sustainability are some of the key issues that this book has addressed. In addition, the book also incorporates a thought provoking analysis of the potential contribution of biowaste-based biogas energy to environmental sustainability from an integrated industrial and domestic case study perspective.
The book Analysis of a Commercial Thermophilic Biogas Plant is a product of a research that identified biodegradable waste materials like domestic/municipal effluence as economically viable alternative source of energy. The proposed Commercial biogas plant was mathematically modeled for urban area clean energy requirement. The capacity of the plant was estimated for a given cycle of operation. A nominal 1500m3 power gas plant was studied characteristically and its performance efficiency evaluated. It was observed that the rate of biogas production is a function of the reactor temperature, pH, substrate concentration, rate of degradation of biomass, and the accumulation of matter in the system due to bacteria growth.
