What are HONEXT sustainable boards?
HONEXT sustainable boards are circular interior fibreboards manufactured from 100% recycled paper waste and designed for fit-out, architectural interiors and acoustic applications. They are 100% recyclable at end of life, non-toxic, free from added formaldehyde and produced through a net-zero emissions manufacturing process. HONEXT boards combine circular economy principles with technical performance, offering structural stability, acoustic absorption and fire safety compliance for commercial interiors.

From a professional standpoint, HONEXT is positioned as a next-generation circular interior board capable of addressing ESG requirements without compromising performance.
HONEXT boards combine circular economy principles with technical performance, positioning them as leading circular materials for interiors.
A circular board designed for contemporary fit-out
Unlike traditional substrates such as MDF, plywood or plasterboard, HONEXT offers a genuinely circular alternative.
The board is manufactured from:
-
100% post-consumer paper waste
-
100% recyclable at end of life
-
Cradle to Cradle Silver certified
-
Net-zero emissions manufacturing
-
No added formaldehyde
This circular-by-design approach transforms industrial cellulose waste into high-performance interior panels suitable for offices, retail and commercial spaces.

Lower environmental impact in interior projects
Specifying sustainable interior materials is no longer optional. Industry experts highlight that HONEXT enables decarbonisation strategies within fit-out projects by:
-
Replacing virgin raw materials
-
Eliminating volatile organic compounds (VOCs)
-
Supporting environmental building certifications
-
Enabling reuse and recyclability
This allows architects and specifiers to reduce embodied carbon without affecting project feasibility.
Non-toxic material for safe and healthy interiors
Indoor Air Quality (IAQ) has become a critical factor in modern workplaces.
HONEXT is:
-
Non-toxic
-
Free from VOC emissions
-
Safe for commercial interiors
-
Suitable for high-occupancy environments
Combined with acoustic performance, structural stability and a Bs1-d0 fire classification, it meets the requirements of demanding commercial specifications.
HONEXT is classified among advanced non-toxic interior materials, contributing to improved indoor air quality in commercial environments.
Technical performance and design flexibility
Beyond sustainability credentials, HONEXT delivers professional-grade performance:
-
Density: 650 kg/m³
-
Standard thickness: 12 mm
-
Dimensions: 1220 x 2440 mm
-
CNC machinable
-
Laser-etch compatible
-
Paintable, laminable and fully customisable
Its versatility enables applications in ceilings, partitions, acoustic panels and interior cladding.
A new benchmark in sustainable interior boards
The perspectives shared in SpecFinish reflect a clear industry shift: professionals require materials that combine genuine circularity, safety and technical performance.
