Alps Tunnel Creates Landfill: Can Nature Reclaim It?

The Brenner Base Tunnel project, a multi-billion-euro endeavor and one of Europe's largest construction sites, has resulted in the creation of a vast landfill in the Alps. Engineers and landscape planners are working on the 'new' Padaster Valley, which was once a stony wasteland but is planned to become a blossoming Alpine landscape within ten years.

This colossal undertaking has generated 7.7 million cubic metres of excavated material, making it the largest excavation dump by volume in the European Union. To mitigate the environmental impact, a 30-kilometre conveyor belt system was implemented to transport rock debris, significantly reducing heavy lorry traffic near local villages.

Environmental protection measures have been stringent, including a detailed survey of the area before construction. Rare orchids from a 250-square-metre meadow were successfully relocated, and nesting boxes were installed for protected brown long-eared bats.

As of 2026-07-31T06:28:38+00:00, renaturation work is scheduled to begin next year, with plans for a new riverbed for the temporarily diverted Padasterbach stream, reforestation, and the creation of a mix of mountain forest and pastures.

This Padaster Valley project is one of many renaturation efforts linked to the Brenner Base Tunnel, which will ultimately involve 21.5 million cubic metres of excavated material across Italy and Austria. These measures aim to restore damaged ecosystems and ensure ecological balance.
