landfill gas

The implementation of projects for landfill gas utilisation is world wide based on very different criteria and temporally very diversified. While in Germany and some European countries only residual landfill gas potentials can be developed (due to the prohibition of deposition untreated waste) there are globally already a huge potential. For example there are in India, Russian or Africa only a view insignificant landfill gas utilisation projects in comparison with the potential. The reason is the stagnating trade with carbon emission certificates or not beneficial laws or payments for the produced electrical power. But in the last years also some requests for planning works were coming from these countries.

But that a good legal base and a good payment for green energy can provide enormous opportunities it can be seen in the project development in Turkey or in Belorussia. In the last 10 years a project scope of 100 MW(el) was developed in Turkey. But an own estimation shows a potential from more than 300 MW(el) - consequently there is a lot of more potential also in the future. In the frame of the up to this time preformed works there were developed new waste deposition technologies, the waste sorting was intensified and adapted degassing systems were implemented. Also biological plant for waste utilisation is in the development.

But in Germany the working area is different. Mainly it is based on - surface seeling of existing landfills, waste treatment, the search for new methods for utilisation of residual gas. The main focus from SEF-Energietechnik GmbH is - gas potential analyses, carrying out expertise and system analyses to increase the residual gas potential, upgrating of existing landfill degasing systems, active system support and regulation for landfill gas collecting systems, overview measurements, planning works and service for landfills with methane oxidation systems or for aerobisation of landfills. SEF owns specialised measurement equipment and a lot of experience for these works.
