Phytoremediation Potential of Bioenergy Plants

The globally escalating population necessitates production of more goods and services to fulfil the expanding demands of human beings which resulted in urbanization and industrialization. Uncontrolled industrialization caused two major problems – energy crisis and accelerated environmental pollution throughout the world.

Presently, there are technologies which have been proposed or shown to tackle both the problems. Researchers continue to seek more cost effective and environmentally beneficial pathways for problem solving.

Plant kingdom comprises of species which have the potential to resolve the couple problem of pollution and energy.

Plants are considered as a potential feedstock for development of renewable energy through biofuels. Another important aspect of plants is their capacity to sequester carbon dioxide and absorb, degrade, and stabilize environmental pollutants such as heavy metals, poly-aromatic hydrocarbons, poly-aromatic biphenyls, radioactive materials, and other chemicals.

Thus, plants may be used to provide renewable energy generation and pollution mitigation.

An approach that could amalgamate the two aspects can be achieved through phytoremediation (using plants to clean up polluted soil and water), and subsequent generation of energy from the phyto-remediator plants. This would be a major advance in achieving sustainability that focuses on optimizing ‘people’ (social issues), ‘planet’ (environmental issues), and ‘profit’ (financial issues).

This book addresses the overall potential of major plants that have the potential to fulfil the dual purposes of phytoremediation and energy generation. The non-edible bioenergy plants that are explored for this dual objective include Jatropha curcas, Ricinus communis, Leucaena leucocephalla, Milletia pinnata, Canabis sativa, Azadirachta indica, and Acacia nilotica.

The book addresses all possible aspects of phyto-remediaton and energy generation in a holistic way. The contributors are one of most authoritative experts in the field and have covered and compiled the best content most comprehensively. The book is going to be extremely useful for researchers in the area, research students, academicians and also for policy makers for an inclusive understanding and assessment of potential in plant kingdom to solve the dual problem of energy and pollution.

His main research areas are phytoremediation, restoration of contaminated sites, and slow release fertilizers. He has published one book with Springer on “Algae and Environmental Sustainability”, as well as 28 research papers in national and international journals, 6 book chapters and 6 popular articles in magazines.?

Dr. Bhaskar Singh received his Ph.D. from the Indian Institute of Technology (BHU), Varanasi, India in 2010 and his M.Phil. from Pondicherry (Central) University, India with a gold medal (2006). Dr. Bhaskar completed his postdoctoral fellowship at Durban University of Technology, Durban, South Africa. He is currently serving as an Assistant Professor at the Centre for Environmental Sciences, Central University of Jharkhand, Ranchi, India. Dr. Singh is currently engaged in teaching in the thrust areas of Environmental Sciences like Environmental Earth Science, Natural Resources, Environmental Chemistry, Environmental Pollution Monitoring & Control Technologies, Environmental Management & Sustainable Development, and Environmental Law & Legislation. He serves as a reviewer for several international journals such as Fuel, Energy, Renewable Energy, Renewable & Sustainable Energy Reviews, Energy & Fuels, Journal of Cleaner Production, Materials Chemistry and Physics, Biofuel Research Journal, Oceanologia, and Journal of Agricultural Biotechnology and Sustainable Development. Dr. Singh is also Treasurer of the Ranchi Chapter of the Society “Professor HS Srivastava Foundation for Science and Society”. His current interests lie in the application of biodiesel synthesis from plant oil and algal biomass, the development of heterogeneous and green catalysts, and the corrosive aspects of biodiesel fuel. Dr. Bhaskar has co-edited one book with Springer titled “Algae and Environmental Sustainability” along with Dr. Kuldeep Bauddh and Prof. Faizal Bux. His publications include 33 research and review papers in peer-reviewed and high-impact international journals, as well as 7 book chapters with reputed international publishers.

Professor John Korstad?is a Professor of Biology and Past Director of the Honors Program at Oral Roberts Univ. in Tulsa, Oklahoma (USA). ?His educational background includes a BA in Geology and BS in Biology from Calif. Lutheran Univ., an MS in Environmental Science from Cal. State Hayward, and an MS and Ph.D. in Zoology from the Univ. of Michigan. His specialty is limnology (lake ecology), with specific expertise in nutrient-phytoplankton (microalgae)-zooplankton interactions. ?He has vast experience in aquaculture, including two sabbatical years conducting research at The Foundation for Scientific and Industrial Research (SINTEF) in Trondheim, Norway, which resulted in three published and numerous technical publications. He began pursuing algae to biofuels research during his Fall 2009 sabbatical leave. His goal is to bring together various industries like local oil refineries, electrical power plants, and cement factories that produce carbon dioxide waste, local industries like waste management landfills, and city sewage treatment plants with high nutrient loads in their waste water, in order to cultivate algae for biofuels. The algae would improve the air and water quality by taking up the waste CO2 and nutrients, while also providing a feedstock for biodiesel and/or ‘high-end’ products like omega-3 fatty acids. This would essentially be a win-win-win situation, and would hopefully develop into a vibrant industry that brings added jobs and revenue to the areas adopting it.
