Greenhouse Gas Emissions Data from Laboratory Biocover Experiment

Description

Data from a laboratory experiment testing different biocovers for landfill technology are published. The data include emissions of methane, carbon dioxide, nitrous oxide and ammonia.

Steps to reproduce

The study comprised three sections, each containing three tube columns. Water-saturated compost mixed with fine-fraction waste was selected as the greenhouse gas (GHG) emission source for all tube columns, as this composition was deemed suitable for laboratory investigations. This emission source was placed at the base of each tube column with a thickness of 500 mm. A 300 mm sand layer was then applied to separate the emission source from the biocover layer. Finally, a 400 mm thick biocover layer was added on top. All measurements were conducted using a Picarro G2508 Cavity Ring-Down Spectroscopy (CRDS) gas analyzer (Picarro Inc., California, USA). • 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 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. • Third section (3 exp.) of the experiment. The experiment was set up on 27 October 2022. The composition of the first biocover used is 25% dried algae, 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.
