Potential of Development of Mechanical-Biological Waste Treatment Plants in Germany

In Germany, there are currently existing 46 Mechanical-Biological waste Treatment plants (MBT-plants) operating with a total capacity of around 6 million tons. Most of the plants meanwhile possess about almost 6 years operating experience and have become an important part of Germany’s waste industry. But there is still a great range of possibilities to optimise the MBT-technology.

In Germany there are currently operating 46 MBT-plants, with a capacity of about 6 million tons. Nearly 25 % of the incoming municipal waste are treated bio-mechanically. The realized varying operation concepts are difficult to compare. According to the background of the German regulatory framework of the AbfAblV (waste storage ordinance) and the 30. BImSchV (immission ordinance) two extreme variations can be generally divided. The aim of the end-rotting process is to create as much waste material as possible and the ideal dry-stabilisation-alternatives have the aim to recycle all emerging solid residue materials energetically and substantially. Beyond that there are currently 20 up to 30 plants in Germany, operating a capacity of 2 up to 3 million tons yearly, which handle the delivered waste by mechanical-physical treatment (MT-plants) to produce Solid Recovered Fuels (SRF). These can be used energetically in coal-fired power plants, in the cement-industry or more and more often in especially constructed industrial waste combustion-plants (SRF power plants).

Most of the currently operating plants with MBT-technology were planned in the years 2001 until 2005 and were constructed under a high pressure of time. Since the middle of 2005 the MBT-plants have to stand the test at the market and comply durable and securely with the high requirements of the German AbfAblV and the 30. BImSchV in the operational practice. According to this background the plants with MBT-technology have been continuously optimised, to cure the teething troubles and to fit on the operation concepts to the permanently changing frameworks on the waste market. Meanwhile the plants with MBT-technology have gained a high procedural standard and emerged into an important pillar in the waste industry.

Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.

Charakterisierung von belüftetem Deponiematerial betreffend Verwertbarkeit und Ablagerfähigkeit

Als ein Teil der Erfolgskontrolle nach dreijähriger Belüftung eines Deponieabschnitts der Kreismülldeponie Konstanz wurde eine umfangreiche Probenahme- und Analysenkampagne durchgeführt. Ziel war darzustellen, mit welchem Aufwand sich von dem behandelten Deponiegut Wertstoffe abtrennen lassen, in welchem Zustand sich diese befinden und ob der Sortierrest sich ohne weitere Vorbehandlung auf einer MBA-Deponie ablagern ließe.
