Title: Investigation of Biogas, Methane, and CO2 Production with the Addition of Urtica Dioica (Dry and Fresh) in a Laboratory Anaerobic Reactor
Keywords: anaerobic digestion, biogas, carbon dioxide, methane, nettle, Urtica Dioica

Abstract: The aim of this study is to evaluate the impact on biogas, methane, and CO2 production with the addition of Urtica Dioica (dry and fresh) in a laboratory anaerobic reactor with a working volume of 350 ml at 37 °C for 54 days. Cattle manure from an eco-farm as the inoculum starter. Nettle Urtica Dioica, which is an inexpensive and readily available weed, stimulates microbial activity and creates a favorable environment for accelerating their growth and reproduction. The results of the measured cumulative volumes—3385 ml of biogas and 1926 ml of methane, with 57% methane and 8% CO2—were obtained by mixing 80% cattle manure and 20% fresh nettle. This provides evidence of the catalytic effect of the fresh nettle addition on the process.
