دانلود کتاب Integrated Wastewater Management and Valorization Using Algal Cultures

Intensive development efforts and linear economic activities since the last century resulted in excessive natural resource use as well as environmental and health problems. When the cost of waste management and health care as well as declining levels of several important natural resources are considered, it is evident that this also represents major economic and social challenges. This new paradigm brought along integrating the concept of sustainability with all anthropogenic activities to create more sustainable means of producing, processing, and consuming the natural resources along with sustainable waste management practices. Among others, circular economy aims at accomplishing a closed-loop system to maximize the recovery of raw materials derived from the waste at end-of-life. The wastes should be considered as “misplaced renewable resources” that can be used again to generate valuable and marketable products, replacing the fossil-based resources. Reducing the carbon footprint of waste management activities, recycling and reuse of valuable materials, wastewater reuse, and bioproduct and biofuel generation from wastes characterize the main features of sustainable waste management. Thus, it is not only an integral part of circular economy but also offers a solid framework to alleviate sustainability and resource efficiencyerelated problems. Algal cultures have been used for nutrient removal from wastewaters for a long time. However, the research on algal biotechnology has been accelerating recently since it can integrate several processes with environmental and economic benefits, such as CO2 sequestration via photosynthesis, nutrient removal and recovery from wastewaters, and production of valuable products such as biofuels, human food, cosmetics, pharmaceuticals, animal, and aquaculture feed and fertilizers. This book revisits algal biotechnology and its potential contribution to sustainable wastewater management, resource efficiency, circular economy, and the United Nation’s Sustainable Development Goals. We would like to express our sincere appreciation to the diverse group of 35 experts from 7 different countries and 16 institutions who shared their experience, work, and vision.
