Why Choose Our HDPE Geomembrane for Biogas Applications
Superior Gas & Liquid Containment
- Biogas digesters require a highly impermeable barrier to prevent methane (CH4) and other gases from escaping. Our HDPE geomembrane offers excellent gas containment properties, ensuring maximum biogas collection efficiency.
- The low permeability of our geomembrane prevents leaks, protecting the surrounding environment from contamination.
Exceptional Chemical Resistance
- Biogas production involves corrosive elements such as hydrogen sulfide (H2S), ammonia (NH3), and organic acids. Our HDPE liner is chemically inert, resisting degradation from aggressive substances.
- For floating covers and exposed applications, our geomembrane is UV-stabilized to withstand prolonged sunlight exposure without cracking or weakening.
- Performs reliably in extreme temperatures (-40°C to +60°C), making it suitable for both hot and cold climates.
High Tensile Strength & Puncture Resistance
- The reinforced structure of our HDPE membrane ensures resistance to punctures, tears, and mechanical stress, even under heavy loads.
- Perfect for underground biogas digesters where soil movement and pressure can compromise weaker liners.
Flexible & Easy Installation
- Available in large rolls and custom sizes, our geomembrane can be welded seamlessly to create a monolithic barrier, eliminating weak joints.
- Lightweight yet durable, allowing for easy handling and quick deployment in biogas projects.
Our HDPE geomembrane is designed for decades of service with minimal maintenance. By choosing our liner for your biogas project, you benefit from:
Reduced greenhouse gas emissions (better methane capture for energy production).
Lower maintenance costs (no frequent repairs or replacements).
Compliance with environmental regulations (prevents soil and water pollution).
