Biodegradable Geosynthetics: GreenLine in Action

With GreenLine, Naue presents a product family that reliably fulfils temporary technical functions and then naturally decomposes. The technical article in the german magazine Geotechnik shows how biodegradable geosynthetics successfully bridge the gap between performance and ecology particularly in sensitive environments such as nature reserves, water protection zones, renaturation projects, and landscape or pathway construction.

GreenLine products stabilise the subsoil during the initial construction phase, provide filtration and separation functions, or offer temporary erosion protection for slopes and banks. Examples include Secutex® Green as a separation and filtration layer in path and trail construction, and Secumat® Green for temporary erosion control on embankments and waterways. Supplied in rolls, the materials are easy to install and support vegetation growth until natural roots take over their function. The result: predictable construction progress, clean site processes and dependable technical performance with reduced maintenance and deconstruction effort.

GreenLine is based on bio-based, fully biodegradable fibres. Once their function has been fulfilled, the materials decompose into harmless residues eliminating costly removal work and minimising site disturbance. For planners and authorities, this means that strict environmental requirements can be met more easily, the degree of intervention is reduced, and lifecycle costs are lowered. This is true circular thinking in construction delivering measurable benefits for both ecosystems and project outcomes.

The article provides a technical overview of GreenLine, describing its material composition, mode of action and typical applications from trail construction and bank protection to temporary slope stabilisation. It also shows how these systems close the gap between engineering performance and environmental protection.
Naue is continuously developing the GreenLine product range, expanding design principles and practical experience from reference projects to make sustainable solutions even more widely applicable in the future.
