This unique compendium provides an insight into the role of emerging marine biorefineries based on macroalgae (seaweeds) in the development of a sustainable use of ocean resources for economic growth-blue economy.The useful reference text shows a complete picture on the motivation to develop seaweed technologies, and how the combination of biology, cultivation technologies and downstream processing with economics can address the social challenges through the blue growth.

"Algae are mysterious and fascinating organisms that hold great potential for discovery and biotechnology." —Dr. Thierry Tonon, Department of Biology, University of York "Science is a beautiful gift to humanity; we should not distort it." —A.P.J. Abdul Kalam In this book, we emphasize the importance of algal biotechnology as a sustainable platform to replace the conventional fossil-based economy. With this focus, Volume 2 summarizes the up-to-date literature and knowledge and discusses the advances in algal cultivation, genetic improvement, wastewater treatment, resource recovery, commercial operation, and technoeconomic analysis of algal biotechnology.

Traditionally, the ocean economy is viewed solely as a mechanism for economic growth. In this business-as-usual approach, large-scale industrial economies have developed the ocean economy through the exploitation of maritime and marine resources, often without consideration of how those activities impact the future health or productivity of those same resources. This has led to aquatic ecosystems being viewed and treated as limitless resources; the marine environment becoming a dumping ground for waste; overfishing diminishing fishing stocks; ocean habitats being degraded from coastal developments; sea-level rise impacting coastal communities and infrastructure; increasing ocean acidification; and the marginalisation of poor coastal communities. Recognising the failings of the traditional ocean economy, there is a transition underway around the world towards the Blue Economy. This concept moves beyond the business-as-usual approach with economic development and ocean health complementary to one another. In the Blue Economy, the environmental risks of and ecological degradation from economic activity are mitigated or significantly reduced. Therefore, economic activity is in balance with the long-term capacity of the ocean ecosystems to support this activity and remain healthy and resilient. This book will provide an overview of the various technologies used to promote cross-sectoral and multi-scalar collaboration, facilitate the integrated management of sectors and resources, foster partnerships between governments and industry, encourage R&D in new technologies in resource use and management, and scale-up innovative financing mechanisms in the development of a Blue Economy. Also, the book will contain in-depth case studies that illustrate how locations, of differing climates, lifestyles and income levels, have implemented technologies to facilitate the development of the Blue Economy. Developing the Blue Economy will provide an accessible resource for practitioners and researchers working in the field on the various innovative technologies being implemented around the world to create a Blue Economy.

Ocean plays a significant role in energy production, human health and economy. Seawater, seaweed, microalgae, yeast, bacteria act as feedstock for biofuels and bioproducts. This book focuses on the application of marine biomass for production of energy, fertilizers, nutraceuticals, pharmaceuticals, cosmetics, bioplastics and other value-added products. It presents technological advancements and optimization strategies for enhancing process efficiency, overcoming challenges and maximizing the potential of marine-based biorefinery. It also describes how marine resources can be applied to wastewater treatment, eco-restoration, environment protection and sustainable development.

The utilization of various types of biomass residue to produce products such as biofuels and biochemicals means biorefinery technology using biomass residues may become a one-stop solution to the increasing need for sustainable, non-fossil sources of energy and chemicals.Refining Biomass Residues for Sustainable Energy and Bioproducts: Technology, Advances, Life Cycle Assessment and Economics focuses on the various biorefineries currently available and discusses their uses, challenges, and future developments. This book introduces the concept of integrated biorefinery systems, as well as their operation and feedstock sourcing. It explores the specificities, current developments, and potential end products of various types of residue, from industrial and municipal to agricultural and marine, as well as residue from food industries. Sustainability issues are discussed at length, including life cycle assessment, economics, and cost analysis of different biorefinery models. In addition, a number of global case studies examine successful experiences in different regions.This book is an ideal resource for researchers and practitioners in the field of bioenergy and waste management who are looking to learn about technologies involved in residue biorefinery systems, how to reduce their environmental impacts, and how to ensure their commercial viability. - Explores a range of different biorefinery categories, such as industrial, agricultural, and marine biomass residues - Includes a Life Cycle Assessment of biorefinery models, in addition to costs and market analysis. - Features case studies from around the world and is written by an international team of authors

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.

Algae offer potential to produce renewable chemicals and fuels using solar energy and carbon dioxide from atmosphere or in flue gases while simultaneously reducing the generation of greenhouse gases. Since these can be grown on marginal lands with micronutrients and macronutrients often present in waste streams, algae-based chemicals and fuels do not compete with foods. Still large-scale production of algae-based fuels and chemicals faces considerable technological and economical challenges and it would by necessity require a biorefinery approach wherein all the possible algal components are converted into value-added compounds. The present series on algal biorefineries represents a forum for reporting the state of the art of different technologies as well as the latest advances in this field. The volume II of this series complements the volume I in terms of the current state of the art. Different chapters in this volume address diverse issues ranging from genetically modifies algae to new products to life-cycle analysis of algal products.
