A MulchandaniDr. Ashok Mulchandani, Department of Chemical and Environmental Engineering, the University of California, USA

Presentation Title: Bio-Nanotechnological Approaches to Environmental Remediation

Abstract: The rapid industrialization and technological advances over the past century has on the one hand improved the quality of life and increased life expectancy, however, on the other hand has seriously compromised our environment. Large quantities of toxic inorganic and organic compounds introduced in the environment as a result of industrialization activities are posing serious health risk to humans. Cleanup of contaminated water and soil and prevention of future contamination from these compounds pose a serious technological challenge. Several physico-chemical methods for treating these pollutants have been developed and tested. However, these approaches are extremely costly, non-selective, introduce secondary contaminants or deplete important nutrients. Bio-based treatments, also called bioremediation, are considered to be eco-friendly and cost-effective, and are gaining acceptability in environmental cleanup applications. Bioremediation employs either naturally existing or engineered microorganisms or enzymes to either accumulate or transform pollutants to less or non-toxic compounds. Development of biotechnological tools for molecular, genetic and metabolic engineering has accelerated the advancement of designer biological materials for several bio-based remediation processes. In this presentation, I will present examples from our research group on engineering microorganisms and microbial pathways for enhanced removal of organic pollutants such as organophosphate pesticides/nerve agents, p-nitrophenol, etc., and heavy metals such as Cadmium, Mercury, Arsenic, etc.

Biography: Dr. Ashok Mulchandani is a Professor in the Department of Chemical and Environmental Engineering at the University of California and the Editor-in-Chief of the Applied Biochemistry and Biotechnology journal.

Paul NathanailPaul Nathanail - University of Nottingham & Land Quality Management Ltd, UK

Presentation title: Sustainable redevelopment – subservient remediation: when sustainable remediation is not enough

Biography: Paul Nathanail is Professor of Engineering Geology at the University of Nottingham and managing director of specialist contaminated land consultants Land Quality Management Ltd. His interest in sustainable remediation stems from a long track record in the broader field of sustainable urban land management. The concept is 'trending' and in danger of losing its impact through misuse on company websites and marketing literature. The plethora of spreadsheets, programs and applets purporting to diagnose sustainable remediation are in danger of cloaking a simple concept with overly elaborate, time consuming and expensive procedures. The middle ground in achieving a step change in how we remediate is to use simple tools and approaches to help identify those remedies likely to deliver optimal net social, economic and environmental benefits.

Ian ThompsonIan Thompson - University of Oxford, UK

Presentation title:Exploiting the potential of nano-scale iron for environmental clean-up

Abstract: Although the potential of iron for environmental clean-up has been exploited for many years, with the introduction of nano-scale zero valent (nZVI) variants the opportunities have increased enormously, but still largely remain unexplored and fully exploited. Their high reactivity for contaminant removal, reaction longevity and low toxicity/cost are just a few of the features that make them so appealing for remediation (metals and organics) of contaminated sites and recovery of resources from end-of-pipe waste waters. The current and future opportunities nZVI offers for providing sustainable de-contamination will be discussed including their role in new hybrid approaches which encompass biodegradation technologies.

Biography: Although he originally trained and worked as a microbial ecologist, Ian is a Professor of Engineering Science. His research group specialises in environmental biotechnology, with particular focus on the manipulation of micro-organisms using physical and engineered approaches (ultrasound, particle acceleration and nanomaterials) for industrial waste water treatment and remediation. Current research projects include the development of microbial based end-of-pipe clean-up systems for treating spent metal working fluids, exploiting nanomaterial-microbial cells interactions, microbial conversion of green waste to useful products, and development of novel nanomaterial-based biocides.
