How can I request a HONEXT® sample?

You can easily request a sample kit by filling out our contact form.

How should HONEXT® panels be transported, handled and stored?

HONEXT® panels must remain flat during transportation and storage, with the front side always facing up. They must be stacked by dimensions and mounted on supports or chocks that allow the batches to be lifted and handled without damaging the material. We recommend HONEXT® pallets to contain a maximum of 30 panels. The edges must be protected whenever the material is handled, especially when unpacking it.

It is recommended to store HONEXT® panels in a space protected from the elements and without high temperature and relative humidity levels, always avoiding sudden changes in these conditions.

Can HONEXT® be laminated?

Yes. HONEXT® can be laminated like any other type of wood-based panels. It can only be recycled if separated from the bonded sheets.

The material withstands well the use of a hot plate press with common industrial adhesives, of a cold plate press with aqueous dispersion adhesive based on polyvinyl acetate (white glue), and of hand lamination with solvent-based polychloroprene contact adhesive (contact adhesive).

You can find more details on how to laminate HONEXT® in our Processing and Handling Manual.

How can I repair HONEXT® panels?

To repair bumps or deep scratches on installed and processed HONEXT® panels, the use of wood putty is recommended.

The panel should be painted with plastic, enamelled or thixotropic paint to obtain a homogeneous colouration both on the original surface and on the areas covered by putty. If the material has not been previously sanded, caulking makes it lose its texture, making repairs slightly visible.

These wood putties allow for the recycling of the material as long as they are applied in small quantities.

How should HONEXT® panels be cleaned?

For regular, everyday maintenance of HONEXT® panels, use a dry cloth or vacuum. For more thorough cleaning, use a moistened cloth with a soft degreaser, then wipe it with a dry cloth. As HONEXT® is a porous material, contact with oily substances must be avoided.

– Avoid using sponges made of steel or other abrasive materials that would scratch the surface
– Avoid banging or cutting the surface with blunt objects which could scratch it and remove its protective layer
– Do not use alcohol, stain removers, thinners, acetone, trichloroethylene, ammonia, bleach, vinegar, anti-limescale cleaners or any other fluid containing these substances
– Do not use abrasive powder cleaners or detergents which could ruin the aesthetic appearance and surface finish of the product
– Do not drag objects across the surface to avoid scratching
– Do not concentrate on one area when cleaning the surface, as this may alter its appearance.

What varnishes, paints, dyes and primers should be used with HONEXT®?

HONEXT® panels can be treated with the most common coating products for wood-based materials, but there are certain recommendations that should be followed to achieve best results.

We recommend the use of water-based products as they align with the sustainability standards of HONEXT®. Any water-based product used must be fast-drying and not be diluted.

Natural products based on waxes and oils commonly used on wood materials also deliver excellent results when applied on HONEXT® panels, respecting the aesthetics of the material while protecting it.

To help the paint cover the natural colour of the panels, a white primer is recommended. Bear in mind that some neutral-colour varnishes might accentuate the natural pigments found in the material, causing darker stains on the panel’s surface.

When applied in small percentages, the below products, also used in natural wood and wood-based materials, do not affect the recyclability of HONEXT®:

– Water-based acrylic paints and varnishes (e.g. FA1019 by ICA Iberia)
– Oil-based paints and dyes (e.g. Naturoil by ICA Iberia)
– Polyurethane or enamel water-based varnishes
– Any primer specified for wood

You can find more about the recommended coating products and how they should be used in our Processing and Handling Manual.

How should HONEXT® be nailed and screwed?

Pinning is a clean and easy way to install HONEXT® with good results. The panels can be pinned on grid structures using a pneumatic nail gun. When installing HONEXT® on a wooden structure, we recommend using PVA glue to minimise the use of pins and avoid the natural bending of the panel.

Wood screws can be used on HONEXT® panels, although untapered sheet-metal or production screws can give even better results. HONEXT® panels can hold screws as well as most softwoods, but it is advisable to drill a pilot hole before inserting the screw to ensure maximum performance.

What adhesives are recommended for HONEXT®?

In general, wood glues offer great bonding results with HONEXT®, as the material absorbs the adhesive better than most wood and wood-based panels. It can be glued without using pins or screws.

Standard industry glues work perfectly, although they may impact the panel’s recyclability. That’s why we suggest using only non-toxic glues.

For optimum performance, we recommend using polyvinyl acetate (PVA or white glue) and methyl cellulose glues.

Check out our Processing and Handling Manual for details on how to apply these glues and ensure the later recyclability of the material.

Can tools and fastening systems for wood be used in HONEXT®?

Yes. Most commonly used tools for wood and wood-based materials can be used to process and transform HONEXT® panels.

Refer to our Processing and Handling Manual for instructions on which tools to use and their mode of employment.

How should HONEXT® be sawed, drilled, sanded, machined or engraved?

HONEXT® panels can be transformed like most common wood-based construction materials.

You can find detailed instructions on how to saw, drill, sand, machine and engrave HONEXT® in our Processing and Handling Manual.

Are HONEXT® panels fire and moisture resistant?

The current reaction to fire of HONEXT® panels is class C-s1,d0. The material will reach class B-s1,d0 by Q4 2021

HONEXT® panels are resistant to moisture and water vapour.

Are HONEXT® panels recyclable?

HONEXT® is a circular production material that allows for 100%, infinite recycling. Once our material reaches its natural end after many years of use, the cycle starts again. We feed the material back into the process and generate a new set of HONEXT® panels.

We recommend working the material in a way that preserves that degree of recyclability.

What are the material’s technical properties and specifications?

HONEXT® panels are 100% recyclable and emissions-free and have excellent mechanical and thermodynamic properties.

Our panels do not not emit formaldehyde or other volatile organic compounds (VOCs) and are Cradle to Cradle Silver Certified and Material Health Silver Certified.

HONEXT® has greater sound absorption properties than drywall and MDF, and is resistant to moisture and water vapor. Its current reaction to fire is class C-s1,d0, with Class B-s1,d0 expected to be reached by Q4 2021.

HONEXT® panels provide better thermal and sound insulation than other materials with similar applications, and it offers greater resistance to bending and is lighter than traditional partitioning materials.

Is HONEXT® Cradle to Cradle Certified®?

HONEXT® is Cradle to Cradle (C2C) Silver Certified, Material Health Silver Certified and GBCe Certified. Our ambition is to reach C2C Golden Certified in the next renewal of the certification.

Is HONEXT® emissions-free?

HONEXT® is entirely emissions-free. It does not emit formaldehyde or any other volatile organic compounds (VOCs) thanks to a unique, nature-inspired process that maximises the bonds between cellulose fibres.

Additionally, our production process is carbon neutral. We source our waste locally to eliminate the need for transportation, and our factory is designed to have zero environmental impact: gas and electricity are generated through waste digestion, and process water is kept in a closed loop, being permanently recycled.

Why is every HONEXT® panel unique?

As our raw material is 100% mixed waste, each HONEXT® panel is different and has a visually unique surface.

The colour of each batch of HONEXT® panels varies slightly within the range of light beige and grey tones depending on the waste used.

The panels sometimes display a set of water stains. These are formed during the material’s production process and come from the dyes contained in our raw materials. The intensity and shape of the stains vary from panel to panel.

The material can also contain traces of plastic coming from post-consumer paper waste and that cannot be eliminated in our process. This plastic melts due to the high temperatures in the drying process, causing darker spots of Ø1-10mm on the material. The surface may also display smaller coloured dots of Ø0,5-1mm caused by the inks present in our raw material. Other particles such as metals or unmelted plastic pieces can also be found.

The aesthetic heterogeneity of HONEXT® panels does not in any way affect the material’s mechanical properties or post-processing.

What is the look and feel of HONEXT® panels?

HONEXT® panels have both sides differently textured as a consequence of the meshes that support them during the production process, with each face displaying a different texture.

The base colour of HONEXT® may vary slightly depending on the residue used to produce the panel, usually staying in the range of light beige and grey tones. Its surface is not homogeneous, varying slightly in tone and exhibiting horizontal watermarks on its front face.

How are HONEXT® panels produced?

The manufacturing process of HONEXT® panels comprises four steps:

First, we analyse, sort, and classify the raw waste based on its composition to achieve a standard product. Based on the quality of the batch of waste, we add in more post-consumer cellulose fibres if necessary.

We then subject the mix to our signature, nature-inspired process, adding organic components to generate stronger bindings between the cellulose fibres with no need for resins.

Next, we add healthy, non-toxic additives to the now upcycled cellulose fibres. Once added, we compress and shape the material into a wet panel.

Finally, we feed the wet panel into a drying tunnel, letting the remaining water evaporate with the high airflow and temperature. HONEXT® is now ready for use.

The 100%-recyclable composition of HONEXT® panels allows us to reclaim them at the end of their natural life cycle and produce a new set of panels.

Where does the waste used to create our panels come from?

The waste fibres used to produce HONEXT® come from primary sludge waste from paper mills and post-consumer cardboard waste. Waste is sourced locally to eliminate the need for transport and related emissions.

Our first functional factory, which is integrated into a landfill in Vacarisses, Spain, is just the first step in a future global network of modular production facilities located right where waste is produced.

What is HONEXT® made of?

HONEXT® panels are made of upcycled waste fibres from paper mill primary sludge and post-consumer cardboard waste – all mixed with non-toxic additives in an innovative, nature-inspired process.

What benefits does HONEXT® have over similar materials?

Thanks to our unique, nature-inspired manufacturing process, HONEXT® panels are zero-waste, resin-free, and 100% recyclable, and have no added emissions of VOCs like formaldehyde.

What is HONEXT®?

HONEXT® is an innovative Barcelona-based company that manufactures a carbon-neutral, circular, biotech process that upcycles waste fibres into fully recyclable and non-toxic panels for construction applications.

Established in 2011 by co-founders Pere and Pol Merino, HONEXT® is based on a research project from Universitat Politècnica de Catalunya. After 10 years of development, HONEXT® panels are manufactured at no cost to the planet at the company’s first functional factory, integrated into a landfill in Vacarisses, Spain.

Why HONEXT®? What makes it so unique?

In the EU alone, paper mills generate more than 7 million tons of sludge waste per year – a volume that only increases as paper recycling rates grow.

Through a proprietary and proven manufacturing process, HONEXT® has managed to turn waste fibres that would otherwise end up in a landfill into a healthy, circular alternative to traditional partitioning and cladding materials that can be endlessly recycled.

All the waste we use to make our panels comes from local sources, which eliminates the need to transport materials across long distances. No transport, no CO2 – a production model that, together with our zero-emissions process results in a neutral carbon footprint.

And this is just the beginning. Our goal is to create a globally distributed network of modular production plants that solves the paper industry’s pervasive waste problem by upcycling waste right where it is generated.
