The Waste-to-Energy Research and Technology Council (WTERT) was founded in 2002 as part of the Earth Engineering Center of Columbia University in New York, U.S.A and the Energy Recovery Council, the U.S. association of waste to energy companies in the U.S.
The Earth Engineering Center (EEC) is member of Columbia University’s Earth Institute. EEC brings together engineers, economists and political scientists to develop solutions to major environmental problems.
Over the years, universities and organizations in several other countries created WtERT organizations which are now members of the Global WtERT Council, Inc. (GWC). WTERT-Canada is hosted by Concordia University in Montreal.
Economic development has resulted in the annual generation of billions of tons of used materials which are a considerable resource and, when not managed properly, constitute a major environmental problem in industrial and developing nations. Therefore the WtERT examines the improved use of waste as a resource and the adequate recovery or disposal of the increasing waste amounts.
The guiding principle of WtERT is that the sustainable management of wastes must be based on science and best available technology and not what seems to be inexpensive now but can be very costly in the near future.
Our mission is to:
- identify the best available technologies for the recovery of materials and energy from urban and other residues of human activity
- conduct research and development as required, and
- disseminate this information by means of its publications, the web, and periodic meetings.
Founding member
Nickolas J. Themelis directs graduate research in the area of sustainable waste management, which includes ways to reduce the use of materials, recycling, composting, combustion with energy recovery, and sanitary landfilling of non-recyclable and non-combustible materials. He is the author or co-author of hundreds of papers and books on this subject, including the International Panel for Climate Change (IPCC), the Encyclopedia of Sustainability of Science and Technology (Springer pub.) and Renewable Energy Sources (Springer pub.). At Columbia University, he has been Chair of the School of Mines and, later, first Chair of the new Department of Earth and Environmental Engineering. He is founder of Columbia’s Earth Engineering Center and of the Global WTERT Council (GWC; www.wtert.org) with sister organizations in fourteen nations, including China and India.
At this time his primary research interests lie in the development of waste-to-energy processes that can be affordable in developing countries. For this work, he has been honored with outstanding contribution awards by the Materials and Energy Recovery Division of the American Society of Mechanical Engineers (ASME, 2011) and the Confederation of European Waste to Energy Plants (CEWEP, 2016). Prof. Themelis is member of the U.S. National Academy of Engineering.
Themelis received a BS in chemical engineering and a PhD in chemical metallurgy (1961) from McGill University (Montreal, Canada). He is the recipient of many scientific awards and a fellow of several U.S. and Canadian societies.

Our Partners
Recognized as one of the world’s foremost research centers on thermal conversion of waste, we collaborate with a multitude of academic organisations and research centers, to advance and promote the recovery of energy and materials from post-recycling commercial and municipal solid wastes, instead of landfilling them.
