[**LyondellBasell (LYB)**](https://www.lyondellbasell.com/?ref=plasticsiq.com) **is collaborating with** [**Armando Alvarez Group (AAG)**](https://armandoalvarez.com/en/?ref=plasticsiq.com) **at its Wesseling site in Germany to implement bio-circular solutions practically. The pair will be demonstrating how bio-circular** [**materials**](https://www.plasticsiq.com/topics/materials/) **can be integrated into daily operations without compromising safety or performance.**

## LYB collaborates with Armando Alvarez Group to implement bio-circular solutions

The Wesseling site is using Form-Fill-Seal (FFS) bags with attributed bio-circular content, certified under ISCC+ standards. The two companies bring together material expertise and [packaging](https://www.plasticsiq.com/topics/packaging/) knowledge to support more [sustainable](https://www.plasticsiq.com/topics/sustainability/) industrial packaging applications. This approach shows how sustainability can be embedded into operational processes while also meeting performance and safety expectations.

#### How it works:

- LYB supplies *Circulen*Renew polymers sourced from bio-circular feedstock to AAG.
- AAG then produces Form-Fill-Seal (FFS) bags with up to 96% attributed bio-circular content, applying an ISCC+ certified mass balance approach.
- Those bags are then utilised at the Wesseling site to package and deliver select materials to customers.

#### Benefits of this approach include:

- Progress toward lower carbon outcomes, with *Circulen*Renew polymers offering up to 44% lower product carbon footprint (PCF) on a cradle‑to‑gate basis compared to fossil‑based alternatives.
- Traceability through third-party ISCC+ certification.
- Enhanced learning across teams and partners.
