Pyrolysis of waste

The management of sewage sludge in an economically and environmentally acceptable manner is one of the critical issues facing society today. In fact, the amount of sludges produced by wastewater treatment plants is going to dramatically increase in both industrialized and emerging countries. Recycling to agriculture (landspreading), incineration or landfilling are the most common disposal routes. However, landspreading leads to an increase in concentration of heavy metals in the soils and indirect emissions into air and water. Disposal by landfilling requires a lot of space and poses a potential environmental hazard. On the other hand, although incineration can provide a large volume reduction and energy recovery, it generates emissions into the air, soil and water. Several technologies presenting an alternative to conventional combustion processes are currently being developed. These technologies mainly include the wet oxidation process, pyrolysis and the gasification process. Pyrolysis has significant advantages over the other methods. Pyrolysis produces more useful products; gas, oil and solid char which may be used as fuels or a feedstock for petrochemicals and other applications. In addition, heavy metals (expect mercury and cadmium) could be safely enclosed in the solid char. Pyrolysis of sewage sludge under different conditions has been studied to investigate the pyrolysis mechanism and to characterize the gases, oils and solid char. Due to the advantages of pyrolysis, in this study, pyrolysis of two different types of sludge was carried out in a fixed-bed
reactor. The main goal of this study was to characterize the composition of gas and liquid products obtained from pyrolysis to determine their utilization area. To understand the thermal behaviour of sludges during pyrolysis, thermogravimetric analysis was also performed. At present, one of the sludges used in this study is disposed of by incineration, the other is disposed off by landfilling

HYDROGEN ROADMAP

In the last years the public interest in hydrogen and fuel cell technology has been significantly growing and it has become a common view that global problems such as security of energy supply or climate change can only be solved with hydrogen from renewable resources in the long term. However, the search for technical solutions for a future hydrogen economy has begun already 50 years ago when the U.S. Air Force tested first hydrogen fuelled gas turbines for jet planes /1/ in the mid fifties and NASA’s space programme evolved. Today hydrogen fuelled cars, home fuel cell units for the generation of power and heat and other consumer applications like portables have reached the stage of demonstration and the market introduction of first products could happen before 2010. In the US and Japan governments have already recognised the necessity to support the introduction of a hydrogen economy by political and fiscal measures. Besides the public funding of research projects for hydrogen technologies a strategic hydrogen roadmap was developed in the US and Japan. Targets for the commercialisation of mobile, stationary and portable applications have been formulated from a socio-economic level. Furthermore, milestones for a corresponding political and legal framework as well as for the technical and economical performance of different applications have been developed.
In Europe, there have been only minor activities, mostly based on member state level. Therefore the High Level Group for Hydrogen and Fuel Cells (HLG) pointed out the urgent need for Europe to create a political framework that “enables new technologies to gain market entry within the broader context of future transport and energy strategies and policies” and develop a European Roadmap for Hydrogen /3/. The HyNet partners in harmony with the European Commission’s DG Research decided to build on the vision of the HLG and to develop a first European Hydrogen Roadmap until the end of 2003 which will be the base for a fully validated roadmap which will be developed by HyWays under the Framework 6 Programme.
