A New Type of War-Related Pollution: Fiber-Optic Drone Tether Debris and War-Derived Polymer Microfibers

Abstract

Contemporary drone warfare is creating environmental materials that do not fit established categories of military debris or conventional plastic pollution. This paper introduces fiber-optic drone tether debris (FODTD) as a new source-category of war-related contamination. Fiber-optic-guided drones use long polymer-coated optical tethers to resist electronic warfare and signal jamming. After use, loss, or destruction, these tethers may remain dispersed across soils, vegetation, agricultural fields, peri-urban areas, and post-conflict landscapes. The paper argues that FODTD should be treated not as incidental battlefield litter, but as a distinct environmental object. Its significance lies less in acute toxicity than in persistence, filamentous morphology, diffuse spatial distribution, and long-term interaction with soils, vegetation, land use, and co-occurring contaminants. The paper also introduces the concept of war-derived polymer microfibers (WDPM), understood as possible micro-scale transformation products of weathered and fragmented drone tethers. Ukraine provides an early large-scale setting for observing this emerging contamination pathway. Recognizing FODTD and WDPM is important for visual mapping, material characterization, soil and vegetation sampling, environmental monitoring, and post-conflict land recovery planning.
