From Biofiltration to Promising Options in Gaseous Fluxes Biotreatment

From Biofiltration to Promising Options in Gaseous Fluxes Biotreatment: Recent Developments, New Trends, Advances, and Opportunities provides an overview on the biological tools used for the treatment of the gaseous fluxes, with emphasis on traditional and perspective options, opening new horizons for research and implementation in practice. It is known that air pollution is an emergent global issue and a priority within the international environmental programs. Moreover, technologies based on biological methods are significantly contributing to the sustainable development concept. Thus this book provides tools for solving air pollution issues in a sustainable manner. These issues can be solved at different levels (e.g., "end-of-pipe" gaseous streams, indoor/outdoor air, closed environments), which can be approached by the different biotechniques presented in the book, from classical biofiltration techniques (part 1) to phytotreatment and microalgae-based techniques (part 2). Although all options have their particularities that make them special for certain applications, a special attention is drawn to the potential of the last one, which offers multiple possibilities for biomass valorization. Scientists from worldwide with relevant experience in their field have been contributed to the development of this book.

• Presents the main biotechnological aspects applied for gas purification, focusing on process understanding, limitations, and capability in different applications
• Promotes a sustainable future of the biofiltration process by enhancing their performance together with the simultaneously economic and environmental impacts
• Implements new aspects of scientific research and development in the field
