GEOMEMBRANES FOR BIOGAS

WHY GEOMEMBRANES ARE A BETTER CHOICE FOR BIOGAS PRODUCTION

HDPE geomembranes are highly effective when used as bottom liner systems and as floating membrane covers in biogas systems. With their ability to seal, they keep rainwater and other contaminants out, and keep liquid and gases contained in the pond. By excluding oxygen, they enhance anaerobic digestion activity. They also seal in odors, an unfortunate result of anaerobic activity.

Key characteristics of geomembranes suitable for biogas containment and recovery applications include excellent UV and chemical resistance, greater mechanical resistance against wind uplift, higher impermeability to methane migration, better multiaxial tensile strain, added flexibility (to ease installation, welding quality and speed), and enhanced stress crack resistance.
