Abstract
The aim of the study is to determine the yield of biogas and methane from slurry with the addition of three species of aquatic plants (Spirodela polyrhiza,Azolla caroliniana and Lemna ninor). Cultivation of traditionally used plants (eg.corn, oilseed rape) to produce biofuels requires arable land, while aquatic plants,as an alternative, can be collected from nature, and due to simple structure, growth rate and favorable chemical composition, they can be used as a primary or supplementary raw material in biogas plants without any pre-treatment. Four samples (control and three aquatic plant species) in three replicates were subjected to anaerobic digestion. Different species produce different amounts of biogas compared to the control (from 504.83 to 881.62 mL g-1 DM). The methane content is from 57.96 to 60.63% depending on the plant species. This indicates the tremendous potential of using these species of aquatic plants to produce biogas and methane.
