Improving the analytical flexibility of thermal desorption in determining unknown VOC samples by using re-collection Duan, Z. Denmark has around 2, landfill sites which continue to emit methane for many years after the depositing of organic waste in landfills ceases.

So even though Denmark has not landfilled organic waste since , methane is still emitted. However, the precise emission level is unknown. Biocover At some landfill sites, the gas is collected with a view to utilizing the energy generated, while other landfills burn it. This is often not possible, however, also because the concentration of methane in the gas is too low—and this is where biocover technology comes in.

For a number of years, researchers at DTU Environment have conducted experiments on the technology, which have shown that oxidizing large parts of methane is possible by placing bioactive layers on top of the waste. Many old landfill sites are only covered by limited amounts of soil, which means the gas can easily be released. In brief, the biocover technology involves sealing the surfaces of old landfills to prevent methane from penetrating them.

Instead—by means of a gas drainage system—the gas is distributed through so-called 'biowindows', which are most comparable to a compost bed. Here the natural microorganisms of the compost transform methane into CO 2 see graphics at the bottom. Among other things, the researchers conducted experiments at a major Danish landfill site, where they reduced emissions from 10 kg of methane per hour to one kg per hour.

Therefore, it is assumed that methane emissions can be reduced by per cent at landfills that implement biocover. Instead, 'biowindows' 1 have been established whereby methane is distributed through a gas drainage 2.

Finally, the 'window' 3 is covered by compost. The microorganisms of the compost ensure that the methane is transformed into CO 2. This has prompted the Danish government to spend approx. DKK million over a three-year period on a subsidy scheme supporting the establishment of biocovers at closed Danish landfill sites. In total, biocover is expected to reduce the equivalent of , tonnes of CO 2 by Consulting engineers needed Associate Professor Charlotte Scheutz, who, together with Professor Peter Kjeldsen from DTU Environment, is responsible for developing biocover, says that while developing the technology itself, a measuring method was devised to identify the landfill sites where biocover will be most effective—and to document the effect.

Measurements carried out within limited areas of the landfill will not provide the full picture, as the gas may leak out across the entire area. Therefore, we have developed a method whereby tracer gas is released on the surface of the landfill site, which can be measured at some distance from the landfill.
