## Material inputs to resolve

Aerospace and defense manufacturing

Northrop Grumman's public waste reporting provides company-level context, while aerospace and defense qualification makes material substitution unusually constrained.

The 2025 Sustainability Report's performance matrix lists 18,640 tons under recycling for 2025. The report excerpt reviewed here does not reconcile that figure to the pound-denominated quantities previously shown on this page, so those quantities are omitted. The matrix figure does not establish a recoverable stream approved for an aerospace material system. 2025 Sustainability Report [5]

**Not established** Site-level volume or recoverable grade

**Open** Site, grade and buyer evidence

**Screening** No commercial claim

**As of** September 18, 2026

- Manufacturing scrap and regulated waste streams
- Material offcuts subject to program and security controls

### Outputs and residuals to resolve

- Recycled material where approved
- Controlled disposal for nonqualifying streams

**First decision:** Material composition, program restriction, recycler approval and end-market acceptance.

## What is disclosed

The 2025 report matrix lists 18,640 tons under recycling. The reviewed excerpt does not reconcile the page's prior pound figures or establish site-level waste coverage.

#### What remains unproven

The report does not identify program-specific alloy, composite, coating, contamination, security or qualification data.

### Decision boundary

Northrop Grumman's public waste reporting provides company-level context, but aerospace and defense qualification makes material substitution unusually constrained. The public record supports one bounded next move: Material composition, program restriction, recycler approval and end-market acceptance. 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 |
|-|-|-|-|
| Manufacturing scrap and regulated waste streams | Composition and specification | Recycled material where approved | Site, volume and buyer evidence |
| Material offcuts subject to program and security controls | Condition and logistics | Controlled disposal for nonqualifying streams | Yield and destination 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

#### Controlled manufacturing-residual screen

Identify one non-program-sensitive residual where material identity and custody can be documented.

**Next evidence:** Material composition, program restriction, recycler approval and end-market acceptance.

#### Qualification path

Separate disclosed company activity from a usable commercial lane.

**Next evidence:** Named site, product grade and technical owner.

#### Commercial boundary

Do not infer customer demand from corporate reporting.

**Next evidence:** Buyer specification, commercial terms and approval.

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

Public reporting is company-level. It does not identify a site-specific stream, recoverable grade, yield, approved recycler or buyer. Program controls and technical qualification must be assessed for each potential pathway.
