Recycling Of Solid Waste For Biofuels And Bio Chemicals

This book presents the latest advances in and current research perspectives on the field of urban/industrial solid waste recycling for bio-energy and bio-fuel recovery. It chiefly focuses on five main thematic areas, namely bioreactor landfills coupled with energy and nutrient recovery; microbial insights into anaerobic digestion; greenhouse emission assessment; pyrolysis techniques for special waste treatment; and industrial waste stabilization options. In addition, it compiles the results of case studies and solid waste management perspectives from different countries.

This book covers sustainable recycling processes (e.g. physical, biological, chemical, and thermo-chemical) of multiple organic solid wastes, provides methods for material recycle of wastes into value-added products including fuels and commodity chemicals that are able to be directly applied to promote manufacturing processes. Aimed at improving the awareness of effective conversion protocols and for developing innovative biomass conversion processes, this text was conceived as a collection of studies on state-of-art techniques and know-how for production of biofuels and chemicals from sustainable recycling of organic solid wastes. Topics in the text are discussed in terms of addressing recent advances, assessing and highlighting promising new methods or new technological strategies and direct conversion of organic solid wastes to process feeds. Highly-recognized authorities, experts and professionals have contributed individual chapters in selected areas to cover the overall topic in a comprehensive manner.

This book is a compilation of process, technologies and value added products such as high value biochemicals and biofuels produced from different waste biorefineries. The book is sectioned into four categories providing a comprehensive outlook about zero waste biorefinery and technologies associated with it. The emerging technologies that potentially put back the lignocellulosic waste, municipal solid waste and food waste into intrinsic recycling for production of high value biochemicals and bioenergy, along with associated challenges and opportunities are also included. The content also focuses on algal biorefineries leading to sustainable circular economy through production of broad spectrum of bioactive compounds, bioethanol, biobutanol, biohydrogen, biodiesel through integrated biorefinery approach. The volume also includes chapters on conversion technologies and mathematical models applied for process optimization. A sound foundation about the underlying principles of biorefineries and a up-to-date state-of-the-art based overview on the latest advances in terms of scientific knowledge, techno-economic developments and life cycle assessment methodologies of integrated waste biorefinery is provided. This volume will be of great interest to professionals, post-graduate students and policy makers involved in waste management, biorefineries, circular economy and sustainable development.

Circular Bioeconomy: Technologies for Waste Remediation covers information about the strategies and approaches facilitating the integration of technologies for wastewater and solid waste remediation. The book highlights the models developed to valorize wastes to produce biobased products. Various chapters presented in the book put a focus on sustainability approaches as a central theme in order to facilitate industries and policymakers to adopt circular economy goals. Since the principal idea of a circular bioeconomy is to transition from a linear economy, it involves advanced technological and designing breakthroughs to reduce waste with a closed looped system. Covers the integration of technologies and processes for waste remediation Narrates recent developments and perspectives on value added products from wastes Summarizes recent developments in lifecycle assessment and techno economic analysis using wastes for sustainable development Offers academicians, engineers, researchers and stakeholders help in adapting suitable technologies for solid waste and wastewater management

Offering a comprehensive approach, this title covers fundamentals, technologies, and management of biological processing of solid waste. It discusses kinetic modeling and synergistic impact evolution during bioprocessing of solid waste, environmental impacts such as greenhouse gas emission from biological processing of solid waste, energy recovery from solid waste, and biodrying of solid waste. It also presents cases and challenges from different countries, successful business models, and economic analyses of various processing options. Aimed at researchers and industry professionals in solid and hazardous waste management, this title offers a wealth of knowledge to help readers understand this increasingly important area.

Waste Biorefinery: Value Addition through Resources Utilization provides scientific and technical information surrounding the most advanced and innovative processing technologies used for the conversion of biogenic waste to biofuels, energy products and biochemicals. The book covers recent developments and achievements in the field of biochemical, thermo-chemical and hybrid methods and the necessities and potentials generated by different kinds of residual streams, including biomass in presumably more decentralized biorefineries. An assortment of case-studies from developing and developed countries illustrate the topics presented, covering energy, chemicals, fuels, food for animal recovery from different waste matrices, and more. Finally, the advantages and limitations of different technologies are discussed, considering local energy demand, government policies, environmental impacts and education in bioenergy. This book will serve as an excellent resource for science graduates, chemical engineers, environmental engineers, biotechnologists and industrial experts in these areas. Provides information on the most advanced and innovative processes for biomass conversion Covers information on biochemical and thermochemical processes and product developments surrounding the principles of biorefining Presents information on the integration of processes and technologies for the production of biofuels, energy products and biochemicals

Waste Biorefinery: Potential and Perspectives offers data-based information on the most cutting-edge processes for the utilisation of biogenic waste to produce biofuels, energy products, and biochemicals – a critical aspect of biorefinery. The book explores recent developments in biochemical and thermo-chemical methods of conversion and the potential generated by different kinds of biomass in more decentralized biorefineries. Additionally, the book discusses the move from 200 years of raw fossil materials to renewable resources and how this shift is accompanied by fundamental changes in industrial manufacturing technologies (from chemistry to biochemistry) and in logistics and manufacturing concepts (from petrochemical refineries to biorefineries). Waste Biorefinery: Potential and Perspectives designs concepts that enable modern biorefineries to utilize all types of biogenic wastes, and to integrate processes that convert byproduct streams to high-value products, achieving higher cost benefits. This book is an essential resource for researchers and students studying biomass, biorefineries, and biofuels/products/processes, as well as chemists, biochemical/chemical engineers, microbiologists, and biotechnologists working in industries and government agencies.
