# TSMC

> TSMC's material-transition opening is the fab itself: ultrapure water, specialty chemicals, gases, wafers and process recovery at a scale where a small yield improvement becomes a physical-economy decision. Its 2025 reporting says waste isopropanol was reprocessed into electronic-grade products. That is a real qualification lane. The first useful unit is one fab, one process family, and one closed-loop chemical specification.

## Material inputs to resolve

Pure-play foundry, advanced logic, specialty technologies and advanced packaging

TSMC's 2025 sustainability reporting identifies water positive, net zero emissions and nature commitments, and describes a cross-regional reclaimed-water exchange model, reprocessing isopropanol waste liquid into electronic-grade products, and adoption of blue ammonia for critical chemicals. TSMC's 2025 annual report states 15.0 million 12-inch-equivalent wafer shipments and more than 17 million of annual capacity. Public sources do not establish one fab-level mass balance for water, chemicals, gases, wafer scrap and recovered-input allocation.

**NT$3.809T** 2025 consolidated revenue

**15.0M** 2025 12-inch-equivalent wafer shipments

**>17M** Annual 12-inch-equivalent capacity

**Water positive** One of TSMC's three 2025 sustainability commitments

- Silicon wafers, photoresists, specialty gases, solvents, acids, bases, metals and packaging inputs
- Ultrapure water, electricity, natural gas and cleanroom consumables
- Spent chemicals, wastewater, wafer scrap and returned process materials available for qualified recovery

### Outputs and residuals to resolve

- Advanced logic and specialty semiconductors, wafers, packages and process services
- Wastewater, spent chemicals, wafer scrap, gases and cleanroom waste
- Fab-level recovery yield, supplier allocation and customer product accounting remain open

**First decision:** Choose one fab and one process family. Map water, chemical, gas, wafer and packaging inputs to recovery, reuse, qualification and product evidence.

## Scale signal

TSMC reports 15.0 million 12-inch-equivalent wafer shipments and more than 17 million of annual capacity in its 2025 annual report.

#### Water signal

TSMC describes a cross-regional reclaimed-water exchange model for industrial users.

#### Chemical signal

TSMC reports reprocessing isopropanol waste liquid into electronic-grade products and adopting blue ammonia for critical chemicals.

#### Evidence boundary

Corporate progress is public. A complete fab and process mass balance remains a qualification task.

### Decision boundary

The public record supports one bounded next move: Choose one fab and one process family. Map water, chemical, gas, wafer and packaging inputs to recovery, reuse, qualification and product evidence. It does not establish a buyer, commercial approval or supply agreement.

## Material flow map

| Material or stream | Qualification gate | Process or destination | Evidence still needed |
|-|-|-|-|
| Ultrapure water | Purity, reliability and watershed context | Fab process and reuse system | Withdrawal, discharge, reuse and product boundary |
| Spent chemicals | Composition, contamination and recovery quality | Distillation or chemical recovery | Input spec, yield and electronic-grade qualification |
| Silicon wafer scrap | Defect class, contamination and sorting | Recovery or disposal | Volume, destination and recovered-material evidence |

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.

## Three defensible entry lanes

#### Make one fab loop auditable

A company-wide water or recycling number is not enough for a customer or process decision.

**Next evidence:** Select fab, process, chemical family, water loop and reporting boundary.

#### Scale electronic-grade recovery

TSMC has publicly described isopropanol recovery. The next question is repeatability, yield and product qualification.

**Next evidence:** Map supplier, recovery process, purity, reuse point and avoided virgin input.

#### Connect yield to material demand

Every defect and rework event carries wafer, chemical, energy and water consequences.

**Next evidence:** Join process-yield data to material use, scrap and recovery for one technology node.

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.

## Material Transition editorial interpretation

The next useful working session starts with: Choose one fab and one process family. Map water, chemical, gas, wafer and packaging inputs to recovery, reuse, qualification and product evidence.
