In recent years, there has been increasing concern over public health threat presented by the introduction of different pollutants in the environment due to anthropogenic activities to a greater extent and natural processes to some extent. Many countries all over the world are currently facing severe problems as these pollutants are haemotoxic, carcinogenic, immunotoxic and teratogenic. There has been an increasing interest in the human health and environmental risk of pollutants present in solid waste or effluent generated by anthropogenic activities. Remediation of polluted sites by applying various physical, chemical, thermal and biological techniques is in practice. The first international conference on 'Sustainable Energy and Environmental Challenges' (SEEC-2017) was organized under the auspices of 'International Society for Energy and Environmental Sustainability' (ISEES) by the 'Center of Innovative and Applied Bioprocessing' (CIAB), Mohali, held from 26 to 28 February 2017. ISEES was founded at IIT Kanpur in January 2014 with the aim of spreading knowledge in the Fields of Energy, Environment, Sustainability and Combustion. The Society's goal is to contribute to the development of clean, affordable and secure energy resources and a sustainable environment for the society and to spread knowledge in the above-mentioned areas and awareness about the environmental challenges, which the world is facing today. ISEES is involved in various activities such as conducting workshops, seminars and conferences in the domains of its interest. The Society also recognizes the outstanding work done by the young scientists and engineers for their contributions in these fields by conferring them awards under various categories. This conference provided a platform for discussions between eminent scientists and engineers from various countries including India, USA, South Korea, Norway, Malaysia and Australia. In this conference, eminent speakers from all over the world presented their views related to different aspects of energy, combustion, emissions and an alternative energy resource for sustainable development and cleaner environment. The conference started with four mini-symposiums on very topical themes, which included (i) New Fuels and Advanced Engine Combustion, (ii) Sustainable Energy, (iii) Experimental and Numerical Combustion and v vi Preface
