Landfills and landfilling in Estonia

From Sanitary to Sustainable Landfilling

Methane generation in landfills

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 collectin...

Nitrogen management in bioreactor landfills.

One scenario for long-term nitrogen management in landfills is ex situ nitrification followed by denitrification in the landfill. The objective of this research was to measure the denitrification potential of actively decomposing and well decomposed refuse. A series of 10-l reactors that were actively producing methane were fed 400 mg NO3-N /l every 48 h for periods of 19-59 days. Up to 29 nitr...

E-voting in Estonia

Estonia has one of the most established e-voting systems in the world. Internet voting remote e-voting using the voter’s own equipment was piloted in 2005 [12] (with the first real elections using e-voting being conducted the same year) and has been in use ever since. So far, the Estonian internet voting system has been used for the whole country in three sets of local elections, two European P...

In Europe, the distribution range of the zoonotic tapeworm E. multilocularis has expanded over the last few decades, and the parasite attracts increasing awareness as a public health issue (2–5).
