Potential for the First WTE Facility in Mumbai (Bombay) India

EEC Publication, Publications|

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.

Developments In Thermal Treatment Technologies

EEC Publication, Publications, WtERT - USA|

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.

Potential for Reducing Global Methane Emissions From Landfills, 2000-2030

EEC Publication, Publications|

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.

Municipal Solid Waste Management in Italy

EEC Publication, Publications|

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%.

Methane Generation in Landfills

EEC Publication, Publications|

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.

Investigations on Corrosion Protective Layers in Waste Incineration Plants

EEC Publication, Publications, WtERT - Germany|

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).
