Resource conservation
Management approach and targets
Together with the Federal Government, DB Group intends to invest heavily in the modernization of the rail infrastructure in the coming years. Due to the extremely extensive construction activities in particular, there is therefore very high demand for resources (especially for concrete ties, track ballast and rail steel), which can contribute to the depletion of certain primary raw materials (e.g. iron ore, basalt, sand). This impact is also associated with greenhouse gas emissions in the supply chain, which we address as part of our net zero target. We are therefore planning to make greater use of low-emission building materials in the coming years. In this way, DB Group is combining its climate protection measures with circular economy strategies. In the downstream value chain, we work with waste disposal companies and processors to recycle our construction waste and reuse some of it as processed material in the infrastructure. Further information on waste management can be found under Output resource management.

The total quantity and share of recycled material for track ballast increased in 2025. As it was not always possible to promote processed, usually more cost-intensive track ballast due to the financing agreements with the Federal Government, no major increase was achieved.
The share of recycled concrete ties used fell further in 2025. The availability of reconditioned concrete ties is still limited. The reason for this is an extended restricted list of removed concrete tie types and years for reconditioning, which was introduced as a safety precaution. The background to this is a precautionary program for the inspection and replacement of concrete ties that has been running since summer 2022.
The slight increase in the share of recycled rail steel is due to the increase in the volume of reconditioned rails and the pilot project for low-emission rails. In 2025, 4,975 t (previous year: 2,695 t) of rail steel from the rail network were reused following reprocessing through reprofiling. The sharp rise is due to improved technical conditions for reprocessing and a framework agreement for the reprocessing of rails that came into force in 2025.
Recycling rate - output resource management
As part of the Group-wide efforts to operate more sustainably, the circular economy also plays an important role in DB Group’s resource output.
The “Circular economy and resource efficiency” technical guideline defines clear requirements and processes to ensure that materials that are no longer required are recycled and disposed of in a resource-conserving and legally compliant manner. The aim is to expand environmental benefits throughout the Group, to effectively utilize synergies and to ensure close cooperation within DB Group. The guideline thus makes a significant contribution to the continuous improvement of operational environmental protection and the implementation of binding standards within DB Group in Germany.

Period from October 1 to September 30.
DB Cargo AG is the only part of the DB Cargo business unit included. The waste is generated by our own activities and is managed by third parties outside DB Group.
The volume of waste increased in 2025. At about 95 %, the largest share was once again generated by construction waste. The reason for the absolute increase in construction waste was the construction projects implemented as part of the corridor modernizations. In 2025, we again maintained our recycling rate at a high level of over 95 %.
