Infineon Technologies AG

Power semiconductors, automotive electronics and water and solvent recovery

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.

37.51M m³ FY2025 water withdrawal

16.32M m³ FY2025 water recycling

32% FY2025 recycling and reuse rate

>1,000 t Solvents recovered and reused annually

• 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.

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

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.

This is a public screening map. It separates company-disclosed flows from open qualification work. It does not convert a destination into a buyer or an announced ambition into operating capacity.

Turn solvent recovery into a qualified supply lane

Recovery is only useful when the solvent clears the same process and safety requirements as virgin input.

Next evidence: Map chemistry, purification, test specification, reuse point and residuals.

Make wafer reclaim visible at product level

A reclaimed test wafer can prevent raw-material waste, but the value depends on cycles and yield.

Next evidence: Join wafer identity, reclaim cycles, defect class, reuse and final route.

Prioritize new-factory water design

Infineon says new Dresden capacity is intended to integrate newer recycling technology by fall 2026.

Next evidence: Define baseline, technology, expected recovery, commissioning evidence and operating result.

Source hierarchy: filings and company disclosures first. The brief states what those sources support and leaves the unresolved plant, grade, permit, buyer and mass-balance questions explicit.

Infineon has a material-transition lane with unusually usable public numbers: 37.51 million cubic metres of water withdrawn, 16.32 million cubic metres recycled, a 32% recycling rate and more than 1,000 tonnes of solvents recovered and reused. The next question is where those loops hold their quality at the process level. The next useful working session starts with: 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.
