Algal Systems for Resource Recovery from Waste and Wastewater
This book provides comprehensive insights on existing technologies and up-to-date advances in the field of waste management and treatment using algal-based technologies via different approaches and systems.
Coverage includes:
Process fundamentals of algae-based wastewater treatment, including metabolic modelling, algal species for resource recovery and algae/bacteria interactions.
Critical insights on the status, major challenges and modern engineering solutions in microalgae-related wastewater treatment processes.
Case studies for coculturing microalgae with methanotrophs for enhanced nutrient recovery from wastewater.
Advanced ways for valorisation of algae-based processes by integrating them with other technologies such as anaerobic digestion, biogas upgradation and bioelectrochemical systems.
Up-to-date information on modern biotechnological approaches for deriving value-added bioproducts and biopolymers from microalgae, including biofuels, pigments and nutraceuticals.
This is an essential textbook for both undergraduate and graduate students pursuing degrees in environmental sciences, technologies, or engineering. Additionally, the book is equally useful for a broad audience, including researchers, engineers, and policy makers interested in the field of algal systems for waste and wastewater management. The book is also tailored to be used as an advanced manual for practitioners and consultancies working in the field of wastewater treatment and resource recovery.

Abstract
Currently, the world is facing major issues of degradation of land by natural as well as anthropogenic activities such as desertification, salinization, industrialization, pollution and population growth. The limited resources and the expanding global population require alternative resources to meet the demands in the future. Microalgae are contemplated as a favorable resource for high-value products, including carotenoids, phycobilin, astaxanthin, docosahexaenoic acid, eicosahexaenoic acid and omega-3/6 polyunsaturated fatty acids. Although the use of algae is not new, the idea of developing high value-added products concerning sustainability, economic viability, nutrition enrichment and environmental friendliness is attracting researchers to explore more about the potential of microalgal flora. Microalgae not only thrive under extremophilic conditions but also do not compete with plants for land resources. Having a short generation period, diverse biochemical composition, low-cost nutritional needs and fixation of CO2 are also significant reasons to promote their products. Also, the biorefinery concept and sustainable cultivation possibilities can substantially add to enabling sustainable production of high-value biomolecules, while proposing opportunities for increasing sustainable food and fuel supplies. However, a few challenges like inadequate domestic demand, constant maintenance of ideal conditions for cultivation and food regulations still need to be overcome.
