Current Developments in Biotechnology and Bioengineering: Sustainable Bioresources for the Emerging Bioeconomy outlines recent advances in bioenergy, biorefinery and the bioeconomy, an essential element for a 21st century bio-based society. The book provides information on biomass and various conversion technologies with different parameters that affect the conversion process. Sections cover different bioproducts, biorefinery systems, energy and greenhouse gas emission balances of bioenergy and biorefinery, and environmental and economic footprints of bioeconomy. Finally, different strategies adopted by developed and developing countries for the promotion and implementation of a bioeconomy concept for a bio-based society are systematically covered. The book provides comprehensive information starting from early progress to the latest trends on bioenergy, biorefinery and bioeconomy with special reference to the developed and the developing countries and the linkage between bioeconomy and climate change mitigation in simple scientific language to appeal to a wider audience. - Includes the fundamentals and concepts of biomass and bioenergy - Outlines recent technology development for biomass conversion - Provides concept for different bioproducts - Covers global strategies and policies on the development of bioeconomies

Interest in anaerobic digestion (AD), the process of energy production through the production of biogas, has increased rapidly in recent years. Agricultural and other organic waste are important substrates that can be treated by AD. This book is one of the first to provide a broad introduction to anaerobic digestion and its potential to turn agricultural crops or crop residues, animal and other organic waste, into biomethane. The substrates used can include any non-woody materials, including grass and maize silage, seaweeds, municipal and industrial wastes. These are all systematically reviewed in terms of their suitability from a biological, technical and economic perspective. In the past the technical competence and high capital investment required for industrial-scale anaerobic digesters has limited their uptake, but the authors show that recent advances have made smaller-scale systems more viable through a greater understanding of optimising bacterial metabolism and productivity. Broader issues such as life cycle assessment and energy policies to promote AD are also discussed.

A sustainable and stable energy supply is essential for a country’s stability and wellbeing. Seychelles, like many small island developing states (SIDS), currently depends on imported energy, in the form of fossil fuels. The high dependence on fossil fuel imports means Seychelles is highly vulnerable to disruptions in global markets. The situation is exacerbated by a reliance on imported food, which accounts for about 70 percent of food consumption. To limit this dependence, it is aiming to increase its reliance on renewable energy to 15 percent by 2030, with a long-term ambition of using 100 percent renewable sources for electricity production. Sustainable bioenergy is one form of renewable energy that can be used to green a country’s energy mix. This Sustainable Bioenergy Assessment report for Seychelles looks at the potential for sustainable bioenergy within the country, considering the country context, conditions and delicate habitat. The report considers sustainable biomass sources from the agriculture, forestry and waste sectors. The assessment was conducted following the bioenergy and food security (BEFS) approach of FAO, and identifies a number of bioenergy pathways relevant for the country. Within the report, the different forms of biomass, their availability and viability are assessed. Livestock, crop and forestry residues, and the biodegradable portion of waste, otherwise destined for landfill, are among the sources of biomass considered. The use of these biomass types and amounts are then assessed from a technical and economic point of view, under different price scenarios, for the production of energy.

This volume presents refereed papers based on the oral and poster presentations at the 4th International Conference on Renewable Energy Sources, which was held from June 20 to 23, 2017 in Krynica, Poland. The scope of the conference included a wide range of topics in renewable energy technology, with a major focus on biomass and solar energy, but also extending to geothermal energy, heat pumps, fuel cells, wind energy, energy storage, and the modeling and optimization of renewable energy systems. The conference had the unique goal of gathering Polish and international researchers’ perspectives on renewable energy sources, and furthermore of balancing them against governmental policy considerations. Accordingly, the conference offered not only scientific sessions but also panels to discuss best practices and solutions with local entrepreneurs and federal government bodies. The Conference was jointly organized by the University of Agriculture in Krakow, the International Commission of Agricultural and Biosystems Engineering (CIGR), the Polish Society of Agricultural Engineering, AGH University of Science and Technology (Krakow), the Polish Society for Agrophysics under the patronage of the Rector of the University of Agriculture in Krakow, and the Polish Chamber of Ecology.

One of the main objectives of the Agreement on Agriculture (AoA) negotiated under the Uruguay Round is to improve the access of developing countries to foreign markets. Constraints in the domestic supply chains of many countries, along with weak marketing support and trade facilitation services, have prevented them, however, from exploiting the opportunities provided by the AoA and by other agreements to improve market access. The aim of this guide is to inform policy analysts on issues that should be considered while developing policies and measures to break the main processing and marketing constraints that prevent their countries from fully exploiting their agrifood export potential.

This book presents the state of the art in biogas production using anaerobic digestion technology, with an emphasis on waste utilization/valorization. Offering a comprehensive reference guide to biogas production from different waste streams, it covers various aspects of anaerobic digestion technology from the basics, i.e., microbiological aspects to prominent parameters governing biogas production systems, as well as major principles of their operation, analysis, process control, and troubleshooting. Written and edited by internationally recognized experts in the field of biogas production from both academia and industry, it provides in-depth and cutting-edge information on central developments in the field. In addition, it discusses and reviews major issues affecting biogas production, including the type of feedstock, pretreatment techniques, production systems, design and fabrication of biogas plants, as well as biogas purification and upgrading technologies. ‘Biogas: Fundamentals, Process, and Operation’ also addresses the application of advanced environmental and energy evaluation tools including life cycle assessment (LCA), exergy, techno-economics, and modeling techniques. This book is intended for all researchers, practitioners and students who are interested in the current trends and future prospects of biogas production technologies.
