> Sika's 2025 reporting makes waste recovery an explicit product and operations issue. Nonrecoverable waste intensity fell to 5.4 kilograms per ton sold, 9.6% below the 2023 baseline, while 58.4% of total waste was diverted from disposal. The sources reviewed do not identify a specific Sika product or packaging stream with a named recovery route.

## Material inputs to resolve

Construction chemicals and building-system materials

Sika reports 5.4 kilograms of nonrecoverable waste per ton sold in 2025, down 9.6% from its 2023 baseline, with 58.4% of total waste diverted from disposal. The public record still does not establish which residual or product family is commercially open.

**-15%** Nonrecoverable waste target per ton sold

**Open** Site, grade and buyer evidence

**Screening** No commercial claim

**As of** September 18, 2026

- Formulation inputs and production residues
- Construction-chemical packaging and end-of-life materials

### Outputs and residuals to resolve

- Recovered material where chemistry permits
- Nonrecoverable waste requiring documented reduction

**First decision:** Safety data, chemistry, packaging format, recycler acceptance and product approval.

## What is disclosed

Sika identifies reuse, recovery and recycling as priorities and sets a 15% reduction target for nonrecoverable waste disposed per ton sold.

#### What remains unproven

No public source identifies a particular plant, formulation, packaging format, recovery partner or specification.

### Decision boundary

The public record supports one bounded next move: Safety data, chemistry, packaging format, recycler acceptance and product approval. 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 |
|-|-|-|-|
| Formulation inputs and production residues | Composition and specification | Recovered material where chemistry permits | Site, volume and buyer evidence |
| Construction-chemical packaging and end-of-life materials | Condition and logistics | Nonrecoverable waste requiring documented reduction | 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

#### Formulation-adjacent recovery

Find a high-volume material family where recovery does not compromise performance or safety.

**Next evidence:** Safety data, chemistry, packaging format, recycler acceptance and product approval.

#### 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.
