European Commission’s “Circular Economy Action plan”
European Commission's "Circular Economy Action plan" Prof Themelis, of Columbia University has a commeny about the European Commission's "Circular Economy Action plan": On waste management, there is not one word about energy recovery by combustion of post-recycling wastes? By now, according to Eurostat data, 28% of EU MSW is used as fuel in waste-to-energy (WTE) plants (450+ of them in EU). http://europa.eu/rapid/press-release_IP-15-6203_en.htm [...]
Comment of Prof. Themelis on the broad use of the word “Incineration” and “Incinerators”
Comment of Prof. Themelis on the broad use of the word "Incineration" and "Incinerators" In many parts of the world landfills are set on fire to create landfill space. Even in the U.S., each year there are about three thousand unintended landfill fires (see Dwyer and Themelis, Dioxins study on Google). These events can be called "incineration" but do not apply to the modern waste to [...]

Overview of Food Waste Composting in the U.S.
According to the State of Garbage, in 2006, forty-six of the fifty states reported tonnage data for “recycled” (composted or mulched) organics, including yard trimmings and food residuals, and/or wood (non-C&D). The total tonnage of organics composted or mulched was 20,368,139 tons in 2006 . This amount represented 5% of estimated Municipal Solid Waste (MSW) generated in the U.S. (387 million tons).Download Publication (pdf)
Use of Statistical Entropy and Life Cycle Analysis to Evaluate Global Warming Potential of Waste Management Systems
The statistical entropy (SE) function has been applied to waste treatment systems to account for dilution or concentration effects on metals. We later extended it to account for carbon flows, especially in waste management systems involving thermal treatment. Now, a simple lifecycle “net energy” metric – encompassing the “lost energy” that would have been gained when high-calorific materials are landfilled rather than combusted with energy recovery – is introduced to account for additional influxes of carbon when using landfilling as the primary disposal method. When combining net energy calculations and long terms effects of landfilling, waste to energy (WTE) becomes a more attractive option for dealing with non-recycled municipal solid waste (MSW). A greenhouse gasforcing factor is also introduced to account for the entropy generating effects of methane. When incorporating forcing and lost energy, WTE performs notably better than landfills with respect to entropy generation and carbon.Download Publication (pdf)
Potential for the First WTE Facility in Mumbai (Bombay) India
The city of Mumbai (Bombay), India is facing a solid waste management crisis. The infrastructure has been unable to keep pace with economic development and population growth, resulting in insufficient collection of municipal solid waste (MSW) and over-burdened dumps. Improper disposal of solid wastes over several decades and open burning of garbage have led to serious environmental pollution and health problems. This study examined the solid waste management process in Mumbai and the potential for implementation of waste-to-energy facilities.Download Publication (pdf)
Developments In Thermal Treatment Technologies
A 2007 WTERT survey showed that the global waste-to-energy capacity (WTE) increased in the period 2001-2007 by about 4 million metric tons per annum. By far, the principal technology used globally for energy recovery from municipal solid wastes is combustion of “as received” MSW on moving grates (“mass burn” or stocker technology). This paper also includes a brief report on the results of a study by WTERT on ways to increase beneficial uses of WTE ash in the U.S.Download Publication (pdf)

Potential for Reducing Global Methane Emissions From Landfills, 2000-2030
By E. Matthews, and Professor Nickolas J. Themelis Sardinia 2007, Eleventh International Waste Management and Landfill Symposium Global generation of municipal solid waste (MSW) is now ~1200 Tg/yr (1 Tg = 1012 g), >70% of which is landfilled. Landfilling of waste contributes ~30-35 Tg methane (CH4 )annually to the world's total CH4 emission of ~550 Tg/yr. Recycling and thermal treatment of waste in wasteto-energy (WtE) facilities contribute equally to diverting MSW from the waste stream destined for landfills and to mitigating CH4 emission. Waste generation is estimated to more than double by 2030 indicating that CH4 emission from waste will rise substantially in the absence of strong policies to reduce landfilling rates. To investigate the potential for future mitigation of methane emission from landfills, we developed reference projections of waste generation, recycling and landfill-gas capture, together with four WtE scenarios ranging from very conservative to very aggressive. Based on these scenarios, global 2030 CH4 emission, including reductions from recycling, range from 86 Tg (most conservative) to 27 Tg (most aggressive). WtE appears to provide the best option for limiting future waste-related emission.Download Publication (pdf)

Municipal Solid Waste Management in Italy
Italy is a European country with population of 58.5 million. It is divided into 20 regions that can be aggregated in three macro-geographical areas (North, Center and South). The generation of municipal solid wastes (MSW) in Italy in 2004 was 31.1 million metric tones. The source - separated collection of recyclables and compostables was 22.7% of the total MSW production. However, the situation is very different between the macro-geographical areas of Italy: the North has reached a value of 35.5%, the Center 18.3% and the South 8.1%.Download Publication (pdf)
Methane Generation in Landfills
Methane gas is a by-product of landfilling municipal solid wastes (MSW). Most of the global MSW is dumped in non-regulated landfills and the generated methane is emitted to the atmosphere. Some of the modern regulated landfills attempt to capture and utilize landfill biogas, a renewable energy source, to generate electricity or heat. As of 2001, there were about one thousand landfills collecting landfill biogas worldwide.Download Publication (pdf)

Investigations on Corrosion Protective Layers in Waste Incineration Plants
Peter Crimmann, Dietmar Bendix, Martin Faulstich, Sulzbach-Rosenberg / D WTERT-Germany 2005
Corrosion in the hot gas area of waste incineration plants is a severe problem that often causes premature damage of components. In general, these components are made of base materials, which are not stable in corrosive conditions (boiler steel). Thermal spraying is an alternative to the most usual process cladding, which has the potential to create cost-efficient protective coatings. Until now, there are still not enough experiences about quality assurance (porosity, oxides) and long run behaviour inside the incineration plants with sprayed coatings. Since many years, ATZ Entwicklungszentrum is involved in the development and/or advancement of materials, technologies, and applications of thermal spraying for corrosion protection. Currently, pipes, coated with different materials and different technologies are tested by different strategies (corrosion tests under laboratory scale and/or directly in incineration plants).Download Publication (pdf)

Management of Solid Wastes in Vietnam
In the past decade, strong economic growth and uncontrolled urbanization have greatly magnified the problems with Vietnam’s solid waste management system, pushing waste management to the forefront of environmental challenges with which it must contend. Not only has there been an increase in the amounts of waste generated, the composition of the waste has changed as well. The current system is already overtaxed due to lack of institutional capacity and insufficient human and capital resources as can be evidenced by low collection rates and inadequate waste facilities. Given socio-economic trends, the issue of how to deal with its solid waste will only become more critical as Vietnam industrializes.Download Publication (pdf)
