Infineon Technologies AG ETR: IFX

Power semiconductors, automotive electronics and water and solvent recovery

IFX
Public materials brief.

Infineon's circularity case is process-specific, which makes it more useful than a generic resource claim. In fiscal 2025 it reports a 32% water recycling and reuse rate and more than 1,000 tons of solvents recovered and reused. The decision is to trace one closed loop, such as a solvent or production-water stream, through collection, purification, requalification and return to a semiconductor process.

Infineon's public fiscal 2025 water disclosure reports 37.51 million cubic metres of withdrawal, 11.59 million cubic metres of ultrapure-water use, 16.32 million cubic metres of water recycling and a 32% total recycling rate. Its waste disclosure reports more than 1,000 tonnes of solvents recovered and reused annually, plus wafer reclaim and repeated test-wafer reuse. Public reporting does not establish one site and process balance joining recovery quality, avoided virgin input, product yield and final allocation.

Material inputs to resolve

  • Silicon wafers, photoresists, solvents, acids, bases, specialty gases, metals and packaging inputs
  • Ultrapure water, cooling water, process water and cleanroom consumables
  • Recovered solvents, reclaimed test wafers, recycled water and reusable wafer boxes

Outputs and residuals to resolve

  • Power semiconductors, automotive, industrial and communications devices
  • Chemical residues, silicon sludge, wastewater, wafer scrap and packaging waste
  • Process-level quality, avoided virgin input and product allocation remain open
First decision: Select one Infineon site and one solvent, wafer or water loop. Join input composition, recovery quality, reuse point, process yield, operating cost and final output.

Control

Infineon develops power systems and semiconductor solutions for automotive, industrial, energy and communications applications.

Water scale

Infineon reports 37.51 million cubic metres of water withdrawal and 16.32 million cubic metres recycled in fiscal 2025.

Circularity signal

Infineon reports more than 1,000 tons of solvents recovered, technically requalified and reused in fiscal 2025, alongside wafer reclaim and test-wafer reuse.

Evidence boundary

Group and site-program metrics still need a process-level material passport.

Decision boundary

Infineon's circularity case is process-specific, which makes it more useful than a generic resource claim. In fiscal 2025 it reports a 32% water recycling and reuse rate and more than 1,000 tons of solvents recovered and reused. The decision is to trace one closed loop, such as a solvent or production-water stream, through collection, purification, requalification and return to a semiconductor process. The public record supports one bounded next move: Select one Infineon site and one solvent, wafer or water loop. Join input composition, recovery quality, reuse point, process yield, operating cost and final output. It does not establish a buyer, commercial approval or supply agreement.
