Biogas‐storage‐ and Biogas‐filling‐facilities – Approvals for construction products and techniques In accordance with the building and water regulations, assessments of fitness for use pursuant to the Building Codes can be issued for construction products and techniques used in storage and filling facilities of biogas plants since September 2015. The article explains which building and water regulations apply to construction products and techniques intended for such use. The requirements in both legislative areas have considerable effects on the characteristics of construction products and techniques intended for contact with fermentation substrates and fermentation residues. In particular, the water regulations set out strict requirements for construction products intended for use in such facilities, which are reflected in high verification requirements for functional reliability and fitness for use. The paper focuses on general aspects, which apply to all approval elaboration and granting processes for construction products and techniques used in the before‐mentioned areas of biogas plants. More specific aspects of approval elaboration will also be addressed, using the example of selected construction products and techniques. The article provides guidance for product manufacturers and for qualified planning and design. It also explains certain specific provisions to be met by specialised firms and qualified professionals within the meaning of water legislation and by operators of biogas storage and filling facilities.
