This book on biogas is about the production and use of biogas with an emphasis on the raw materials and processes suitable for use in Southeast Asia. It is a gas formed when organic matter decomposes in an anaerobic digestion process. It can be made from any organic substance but the most economic are organic products from waste such as agricultural or general household waste, sewage, manure, municipal waste or food waste. As this raw material can be renewed indefinitely, biogas produced from it, is considered a renewable energy source. Worldwide interest in renewable energy sources is gathering momentum especially as concern for climate change mounts. Biogas generation helps reduce reliance on the use of fossil fuels. Producing biogas through biodigestion is non-polluting as there is no combustion or energy addition especially in the warmer climes of Southeast Asia. In this region, poorly managed landfills allow toxic liquids to drain into underground water sources. If instead, these wastes were used in a biogas plant, water pollution would be reduced. The same argument could be made for the local air quality. Therefore, biogas generation, in addition to producing renewable energy, also improves local water and air quality. The solid end-waste product of the biogas generation process is enriched natural organic matter (digestate), which can be substituted for chemical fertilizers, providing another environmental benefit to biogas. This book is primarily concerned with the production of biogas. From the raw material pre-treatment to the reactor design and operation to the post-treatment system, this book covers all aspects of production. There are many types of biogas reactors, each with their own advantages. Which reactor to select depends on the type and quantity of raw material, land area available and climate, among other factors. This book provides information on selecting and operating a suitable biogas system for interested parties bethey governmental, NGO¿s, private companies or individuals. Biogas contains primarily methane (CH4) and carbon dioxide (CO2). It may also contain small quantities of carbon monoxide (CO), hydrogen sulfide (H2S), moisture and siloxanes. Extracting the methane from all other gases is called biogas upgrading and the output is then referred to as biomethane. These upgrading processes are not the subject of this book as they are already the subject of a previously published book.

This book examines carbon-based nanocomposite materials and their application in various environmental fields, such as wastewater treatment, and air and soil remediation.

This book highlights the present scenario of energy demand and power generation technologies in tropical countries.

This book describes for first time the synthesis and intensified process design in the production of top biofuels. The production of biofuels is not new. In 2019, global biofuel production levels reached 1,841 thousand barrels of oil equivalent per day, in stark comparison to the 187 thousand barrels of oil equivalent per day that was produced in 2000. Growth has largely been driven by policies that encourage the use and production of biofuels due to the perception that it could provide energy security and reduce greenhouse gas emissions in relevant sectors. From a technical point of view, almost all fuels from fossil resources could be substituted by their bio-based counterparts. However, the cost of bio-based production in many cases exceeds the cost of petrochemical production. Also, biofuels must be proven to perform at least as good as the petrochemical equivalent they are substituting and to have a lower environmental impact. The low price of crude oil acted as a barrier to biofuels production and producers focussed on the specific attributes of biofuels such as their complex structure to justify production costs. Also, the consumer demand for environmentally friendly products, population growth and limited supplies of non-renewable resources has now opened new windows of opportunity for biofuels. The industry is increasingly viewing chemical production from renewable resources as an attractive area for investment. This book uniquely introduces the application of new process intensification techniques that will allow the generation of clean, efficient and economical processes for biofuels in a competitive way in the market.

This book shows possible solutions to how a profitable energy supply can be implemented with almost no population resistance. Worldwide, more than 80 % of our energy needs are still covered by fossil fuels. Under these circumstances, can climate change still be stopped?Essential technologies for usage of wind energy with an emphasis on high-altitude wind utilization are presented. Airborne wind energy is one of the most promising technologies to enable a renewable energy turnaround in an economical way. The main problem of conventional renewable energy is the insufficient availability. To ensure a 100 % supply of renewable energy, enormous and very expensive storage capacities would have to be built up.How we can cover our entire energy needs (electricity, mobility and heat) in the future without fossil fuels, without risking the competitiveness of our economy, is shown in this book.

This book reviews the history and evolution of district heating networks, with a focus on current and future issues of the district heating sector. Novel developments in the field of low temperature district heating are studied, limitations for safe operation and avoidance of bacteria are considered, and the associated improved performance of the system with fewer network losses is presented.This book showcases how the evolution of district heating networks is linked to the increased use of renewables and de-carbonized heat sources with specific focus to waste heat streams and solar energy systems. Considering the novelty of these technologies, technological developments and funding schemes for these investments are still immature to some extent. For that reason, a comprehensive review of the main aspects of energy planning as well as district heating economics and financing schemes for large-scale investments in renewable energy systems for district energy systems is performed.In the light of digitalization, networks are increasingly monitored, allowing for a drastic change in the approach for network operation. This book also explores the increased digitization and monitoring of networks and how this impacts network operation.This book is of interest to engineers, academics and officials interested in energy systems, presenting readers with the key concepts and tools to adapt to the evolution of district heating into an integrated, digitized and higher performing system.

This book examines the role of the evaluation models in decision-making processes for the construction of circular cities in the digital revolution. In particular, the book explores the need for a rethinking of development models proposed by the circular economy which requires the valorization of natural, social and economic capital. Urban environment represents a crucial field of analysis in which applying the circular-economy principles in order to steer a course towards a sustainable economy characterized by processes meant to create value instead of extracting it, which put a step forward in the pathway towards a better future in terms of economic, environmental and social effects and desirable outcomes. In this context, the design of urban regeneration processes and housing environments requires the adoption of inclusive analysis/assessment models combined with the structuring and organization of public/private investments that can contribute to creating positive natural and social impacts as well as economic and financial returns. This fundamental paradigm shift is accentuated in the current context, in which the digital revolution is reinventing the future and calls for a rethinking and reformulation of value systems in the era of technological process innovations, while respecting economic, natural and social ecosystems.
