Digital material passports - HONEXT®

This is part of the 'Unlocking sustainable designs through digital material passports' exhibited at The Summit — BE-ST Fest '23.

This material started with a vision to protect the planet and a challenge of how the polluting residue from paper and cardboard could be upgraded into something useful and valuable.

HONEXT® comes from waste and aims never to become waste again. These boards are made from primary paper waste sludge that is upcycled into non-toxic, recyclable, flame-retardant boards.

They are a bio-based, circular and carbon-negative alternative to traditional fiberboard, totally non-toxic and resin free. Lightweight, strong and with excellent acoustic properties, this product is fully recyclable and comes with a take-back system.

What is a digital material passport?

A material passport is a digital document listing all the materials that are included in a product or construction during its life cycle in order to facilitate circularity decisions in supply chain management at the end of the building life.

At Cundall, we want to create a passport for materials and products that will also provide information before its use, so designers and contractors have a better understanding of the materials and their impact on the embodied carbon and health well-being of a project, facilitating the inclusion of the best low carbon and healthy materials that align with their design.
