Abstract

Due to the harmful effect on the environment, landfill gas has to be collected and processed. One of the possible solutions would be to cover the landfill with a bioactive layer, where methane is oxidized. The main goals of the closure project at Kudjape landfill were to extract the fine < 40 mm fraction from the landfill in order to construct a methane degradation cover and to transform the closed landfill into a recreational area. Multi-purpose pathways were designed to cover the remediated landfill and were connected to the existing trails nearby. The trails can be used for jogging, hiking or biking and during winter time, for skiing and sledging. The surrounding area was cleaned from fly trash and new vegetation was planted into the cover layer. Car park and rest areas were created to attract people. The installation of the methane degradation layer along with the landscape restoration were finished in autumn 2013. Soon after the restoration it was noticed that some of the planted trees were not adapting to the environment and died off. The current study describes the extent of die-off over time, focuses on understanding the reasons for vegetation failure, and proposes measures to correct them. The research continues to monitor the processes within the methane degradation cover layer in order to provide recommendations for similar projects in the future.
