The Danish Biocover Initiative - Methane Mitigation at Older and Smaller Landfills

View Case Study

Summary

In 2017, the Biocover Initiative was established with governmental support to obtain methane emissions reductions from older landfills containing organic waste. Due to their decreased cost efficiency, older and smaller landfills present a challenge for utilizing landfill gas for energy purposes. The project relies on bio-oxidation technology which microbially converts methane to biogenic carbon dioxide by filtering the landfill gas through compost layers. Preliminary results from 18 of the 22 established systems show an average methane oxidation efficiency of almost 70% higher than the average extraction efficiency of Danish landfill gas utilization facilities (50%).
