Biogas production potential from reeds

Abstract

Aim of this research was to study the use of reeds for biogas production. Reeds from the Pape lake area were selected for anaerobic digestion experiments in laboratory. Reeds were chopped and prepared in four groups from 1 mm up to 20 mm. Their chemical and physical properties were analyzed. The results show more methane can be extracted from green reeds 0,281 lCH4/gDOMadd and from dry reeds 0,226 lCH4/gDOMadd-the smaller reeds were chopped the greater methane yield. Experiment results show reeds are more useful in biogas production when in cofermentation with other raw materials. Profitable biogas extraction from reeds can be accomplished in adjunction with sapropel and fertilizer production.
