Imagine that you are the mayor of a city named Metropolis and are in Charge of School logistics. Before doing so, you might have to ask yourself a few essential questions. What kind of transportation will you provide? Who will it benefit: students, staff or both? Where will the service be provided? When will it be provided: in the evening, morning? And finally, how much will it cost? All these essential questions need to be answered before starting to implement this project and to buy your buses. By doing so, planning, financing, building and operating the chosen mean of Transportation will become an easier task. After that, your political decisions will direct the choice of implication of private sector on the different aspects of your project.
Regenerative Thermal Oxidation in the Cement Industry – Technology and Operation –
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
The cement industry plays a pivotal role in meeting society’s needs for housing and infrastructure. Cement is one of the most important and widely used commodities in the world and is therefore a key ingredient of economic development. Current world production of cement is well above 4,500 million tons per year and growing.
The Added Value of the Balance Method for Waste-to-Energy Operators and National Authorities

Different directives of the European Union may require operators of Waste to Energy WTE plants to monitor the composition of their waste feed with respect to the Content of biomass and fossil organic matter. The mass fractions of both materials are not only of relevance for the amount of fossil and thus climate relevant CO2 emissions of the plant, but also for the ratio of renewable energy generated, as biomass in wastes is considered as renewable energy source.
The Market for Mechanical Biological Waste Treatment Plants in Europe
© TK Verlag - Fachverlag für Kreislaufwirtschaft (9/2016)
Both the number and capacities of mechanical biological treatment plants (MBT plants) have increased significantly in the past years. In late 2015, about 490 MBT plants were active in Europe, reaching a disposal capacity of circa 47 million annual tons. However, despite its steady growth, the MBT market showed volatility. The market development peaked in 2005/2006, with the commissioning of about 80 plants with a capacity of circa 9 million annual tons. In 2015, about 13 new facilities with a capacity of around 2.2 million annual tons went online. The MBT market has also shifted geographically, because the European countries have started implementing the EU Landfill Directive in different years. After MBT plants had mainly been constructed in Southern Europe, Germany and Austria before 2006, investments shifted towards the UK and more recently, towards Eastern Europe. In the coming years, an ambivalent development is expected. Whereas further MBT plants will be constructed in countries still sending large shares of their MSW to landfills, MBT technology will experience increasing pressure in the countries with low landfilling shares.
