Application of Anaerobic Digestion for the Treatment of Municipal Solid Waste in Several Projects

In a circular economy there can be no place for waste announced EU Environmental Commissioneer Janez Potocnik in his opening speech for the green week in June 2014 in Brussels. This year´s topic Circular Economy - saving resources, creating jobs showed a clear sign and dedicated this years congress in the opening speech to the circular and resource economy and therewith to the waste management economy.
In the resolutions taken at environmental summit conferences in the last 20 years priority focus was always given to closed circular economy processes to save natural resources and to reduce CO2 emissions, which have their origin in the use of fossile fuels. This aspect has been taken over by the European Union long time ago and the EU directive 1999/31/EC where article 5 considers the limitation of organic materials to be landfilled.

This EU directive 1999/EC/31 has been interpreted differently in several member countries of the EU and consequently has been converted into national laws differently. Landfill criteria, as criteria for the biological degradation or the remaining biogas potential have been established - within others - by law in different countries. Further requirements, such as calorific value, TOC, leachate quality, etc. have been introduced.

In order to reach a reduction of organic material in the landfills a big focus has to be layed on the source segregated organic household waste, e.g. bio-waste, food and kitchen waste and industrial organic waste streams such as end of lifetime food waste, food waste from restaurants and big kitchens, …. As one of the leading countries in source segregation of organic household waste Germany has now put forward the obligation for the municipalities to introduce the source segregation of organic waste by October 2015. Actual numbers show that even in Germany more than half of the population is not yet even connected to the source segregation of organic waste and more than a quarter of the waste disposal authorities do not even offer a brown bin to their citizens. Estimations show, that even Germany is already collecting 4.3 million tons of bio-waste there are another 4.3 million tons of bio-waste disposed off together with the residual waste.
