The study consisted of three sections in which three tube columns were established in each section. Water-saturated compost was chosen as the source of greenhouse gas (GHG) emissions for all tube columns, and it was mixed with fine-fraction waste. This specific mixture was selected due to its suitability for laboratory investigations. The mixture, serving as the source of GHG emissions, was placed at the base of the tube columns with a thickness of 500 mm. A layer of 300 mm of sand was then added on top of this layer to separate the emission source from the Biocover layer. Finally, a 400 mm thick layer of biocover was applied at the top. All measurements were performed using a Picarro G2508 Cavity Raging-Down Spectroscopic Gas measurement device (Picarro Inc., USA, California). • First section (1 exp.) of the experiment. The experiment was set up on 6 June 2022. The composition of the biocover used is 60% fine-fraction waste, 20% soil, and 20% compost. 41 measurements per column, 123 measurements in total. • Secound section (2 exp.) of the experiment. The experiment was set up on 26 August 2022. The composition of the first biocover used is 25% stabilised compost, 25% fine fraction waste, 25% gravel (0-20 mm), and 25% ash. The Composition of the second biocover used is 40% fine fraction waste, 40% dried algae and 20% chernozem . 30 measurements per column, 90 measurements in total. • Third section (3 exp.) of the experiment. The experiment was set up on 27 October 2022. The composition of the first biocover used is 50% fine fraction waste and 50% clay soil. The Composition of the second biocover used is 40% fine fraction waste, 40% clay soil, and 20% cellulose (shredded paper). 36 measurements per column, 108 measurements in total.
