Recovering energy from waste offers dual benefits – a) improved waste management, and b) provision of reliable energy to households, institutions and commercial entities. In this report, we present a socioeconomic assessment of three energy business models (briquette manufacturing, on-site (public toilet) energy generation, and agro-waste electricity generation) based on feasibility studies carried out in the city of Kampala, Uganda. We assess the potential economic, environmental and social impacts of waste-to-energy business models taking into consideration a life cycle of emissions to provide decision makers with the overall costs and benefits of the models to society versus a business-as-usual scenario.

On-site sanitation systems, such as septic tanks and pit latrines, are the predominant feature across rural and urban areas in most developing countries. However, their management is one of the most neglected sanitation challenges. While under the Millennium Development Goals (MDGs), the set-up of toilet systems received the most attention, business models for the sanitation service chain, including pit desludging, sludge transport, treatment and disposal or resource recovery, are only emerging. Based on the analysis of over 40 fecal sludge management (FSM) cases from Asia, Africa and Latin America, this report shows opportunities as well as bottlenecks that FSM is facing from an institutional and entrepreneurial perspective.

Handbook of Energy and Environmental Security educates the reader about the wider dimensions of the distinctive yet intertwined subjects of 'energy security and 'environmental security'. The book uniquely addresses these two increasingly important topics in a comprehensive and composite manner, describing the concepts and wider dimensions of energy- and environmental security in technological, economic, social and geopolitical perspectives. Divided into three main parts, the book deals with the subject of energy security in terms of its concepts, broader dimensions and allied issues, focuses on environmental security, and covers subjects in a cohesive manner, discussing their important interfaces and commonalities. Providing valuable scholarship for academics, researchers and analysts in the fields of energy and the environment, and using case studies to illustrate national and international levels, this is a valuable resource for energy- and environmental security challenges, especially in the areas of sustainable development and climate change. - Discusses the critical subjects of 'energy security' and 'environmental security' in a composite manner - Incorporates up-to-date data, case studies and comparative assessments - Energy and environmental policy frameworks are covered from the perspective of both developed and developing countries

Substitute Natural Gas from Waste: Technical Assessment and Industrial Applications of Biochemical and Thermochemical Processes provides an overview of the science and technology of anaerobic digestion and thermal gasification for the treatment of biomass and unrecyclable waste residues. The book provides both the theoretical and practical basis for the clean and high-efficiency utilization of waste and biomass to produce Bio-Substitute Natural Gas (SNG). It examines different routes to produce bio-SNG from waste feedstocks, detailing solutions to unique problems, such as scale up issues and process integration. Final sections review waste sourcing and processing. This book is an ideal and practical reference for those developing, designing, scaling and managing bio-SNG production and utilization systems. Engineering students will find this to be a comprehensive resource on the application of fundamental concepts of bio-SNG production that are illustrated through innovative, recent case studies. - Presents detailed scientific and technical information - Describes up-to-date concepts, processes and plants for efficient anaerobic digestion and gasification of wastes and syngas utilization - Compares gasification with anaerobic digestion for different situations - Proposes alternative strategies to increase efficiency and overcome energy balance limitations - Includes benchmarking data and industrial real-life examples to demonstrate the main process features and implementation pathways of bio-SNG systems from dry and wet waste, both in developed and developing countries

Where modern heating and cooking fuels for domestic, institutional, commercial and industrial use are not readily available, briquettes made from biomass residues could contribute to the sustainable supply of energy. This study reviews the briquette making process, looking at the entire value chain starting from the type and characteristics of feedstock used for briquette making to the potential market for briquettes in developing countries. It also analyzes the role that gender plays in briquette production. Depending on the raw materials used and technologies applied during production, fuel briquettes come in different qualities and dimensions, and thus require appropriate targeting of different market segments. Key drivers of success in briquette production and marketing include ensuring consistent supply of raw materials with good energy qualities, appropriate technologies, and consistency in the quality and supply of the briquettes. Creating strong partnerships with key stakeholders, such as the municipality, financiers and other actors within the briquette value chain, and enabling policy are important drivers for the success of briquette businesses.
