Send The Design, Not The Furniture: How TRIBOO Is Trying To Scale Circular Interiors

A year after MaterialDistrict profiled founder Marc van der Heijden, TRIBOO is working on the parts of its circular furniture model that no single product can prove: a shared production network, soft seating designed to be taken apart, a supplier collective and environmental figures that can be used in a tender.

At MaterialDistrict Utrecht in March, TRIBOO did something more revealing than displaying finished furniture: it put a large-scale YIZUMI robot to work on the exhibition floor and printed a piece from its NeverEnding Furniture collection live. Around the printer stood the rest of the company’s circular toolkit: lightweight Greengridz table tops, Nexus tables finished with SeaWood, EverUse acoustic panels clad in i-did felt, and a table and vase printed from Dutch roadside grass, developed with Waardewenders.

MaterialDistrict’s 2025 profile of Van der Heijden covered the founding idea: local waste streams, parametric design, distributed 3D printing and furniture offered as a service. The question one year on is not whether TRIBOO has launched more circular products. It has launched several. The question is whether the system behind them is becoming repeatable, measurable and scalable.

A Platform and a Network Instead of a Warehouse

The most consequential change is in production. NeverEnding Furniture has always rested on the idea that a digital design can be manufactured close to where it is needed, from recycled plastics and fibre waste. Since TRIBOO and YIZUMI Germany signed a partnership at Formnext in November 2025, that idea has become a network plan. In June, the two companies said the first steps of a standardised international network were complete, with NeverEnding designs printable on YIZUMI systems in the Netherlands, Germany, Belgium and Brazil. According to TRIBOO, the print farms use the same robots, logistics and recycled materials in every country, so a design can move between them as a file, while its designer receives a fee per sale.

TRIBOO is also YIZUMI’s sales agent for these large-scale printers, so the network is a distribution channel both for furniture designs and for the machines that make them. The individual print farms have not been named and no production volumes have been published. An April announcement of what the companies called a world speed record for large-scale furniture printing is best read the same way: a statement of ambition rather than an independently verified benchmark.

The principle deserves to be taken seriously all the same. If machines, materials and process settings are standardised enough, the same design can be produced in several places without shipping bulky finished furniture across borders or holding stock. It also changes what a designer delivers: not only the table, but the file and the rules by which it can be made. The open question is one that specifiers will recognise. Consistent quality across print farms favours consistent feedstock, while the environmental case rests on local, variable waste streams. How the network reconciles the two will decide how local its local production really is.

One Chair, One Body

A collaboration with the Belgian company Nozzle shows a second use of the same technology. Nozzle’s UP office chair is configured from a 3D body scan and printed locally. According to the companies, the chair is modular, so parts can be repaired, adjusted or replaced, and printed parts made from upcycled waste can become feedstock for new chairs. TRIBOO offers it as a complete workstation with a height-adjustable Greengridz desk and an EverUse screen. Here, digital production is not only a route to local manufacturing, but a way to make a product for one person without returning to bespoke production.

The Harder Problem: Soft Seating

Tables and planters are relatively easy circular products. Upholstered seating is harder: a conventional sofa combines foams, textiles, boards, glue and staples that are difficult to separate at the end of its life. TRIBOO’s PUZZL collection, developed with CircleFoam Sustainable Products, is therefore a better test of its approach than another table.

PUZZL combines recycled textiles (wool, polyester and i-did felt), recycled EPS for the frame and recycled PU foam and latex, both from CircleFoam, Greengridz panels and 3D-printed parts made from recycled plastic or natural fibres. TRIBOO says the parts are assembled without glue or staples, so each can be separated into its own material stream. Returned seats are refurbished first; at the end of their life, the materials are to be recovered for the next generation of PUZZL, and TRIBOO pays a raw-material fee of €0.25 per kilogram on return. The first model, Tessella, is also available through TRIBOO’s furniture subscription.

The compact Shard, added in August, pushes the idea further. Rather than adding material to make a fully self-supporting object, it rests against the wall, which suits pods and alcoves, while remaining unanchored and easy to move. Circular design here is less about substituting a recycled material than about asking how much structure a product needs at all. TRIBOO says an industrial supply chain is already in place to recycle every component and remake it into the same seat. What a collection launched in May cannot show yet is that loop in practice: a seat returned, taken apart and remade.

From One Supplier to an Ecosystem

Scaling circular interiors is also an organisational problem. An architect rarely specifies only a table top; a workplace combines furniture, flooring, lighting, acoustics and kitchens, each with its own supply chain and end-of-life route. In June, nine companies launched Captains of the New Industry: TRIBOO, Alvero, Dekker Zevenhuizen, Signify, i-did, CircleFoam Sustainable Products, Studio Wae, SeaWood and Nowa Kitchen. Through any one member, a client can reach the combined range.

Several members already appear inside TRIBOO’s own products: Dekker Zevenhuizen makes the Greengridz panels, i-did supplies the felt for the EverUse screens, SeaWood the finishes on the Nexus tables, CircleFoam the foam in PUZZL and Signify the lighting above the printed tables. The collective partly formalises a supply chain that already existed. That is not a weakness, since a chain that works is a better starting point than a new one. The partners say they will present their first joint projects in the coming period, and that is where its value will show.

From Claim to Number

Measurement is the strand that needs the most care. Greengridz has an MRPI EPD, verified by Ecoreview and based on an LCA by SGS Search under EN 15804+A2. The declaration was first issued in 2022, updated in April 2024 and is valid until 2029. It covers the whole life cycle, from raw materials to end of life, where 80 per cent of the MDF is assumed to be recycled into activated carbon.

The EPD puts the climate impact of a one-metre Greengridz top, 600 millimetres wide and 38 millimetres thick, at 9.3 kilograms of CO₂ equivalent over its life: about 15.5 kilograms per square metre. TRIBOO compares that with particleboard and plywood tops of the same size, over the same life-cycle stages: 28.5 and 39.5 kilograms per square metre. That puts Greengridz about 45 per cent below particleboard and 60 per cent below plywood. On the Environmental Cost Indicator (MKI), calculated with the current Dutch method, the figures are €3.85 per square metre for Greengridz against €6.07 for particleboard and €11.68 for plywood.

The CO₂ figure for Greengridz comes from its EPD. The figures for particleboard and plywood come from separate LCAs by the same consultancy, checked by the same verifier but not published as EPDs. The EPD lists the MKI only under the previous calculation method; the current-method figure for Greengridz was supplied by TRIBOO.

The Next Test Is Repetition

Taken individually, these are incremental steps: a digital furniture platform with an international print network in its first phase, a chair, a seating system, a collective, a number. Together, they show where the circular furniture debate is heading. Proving that an attractive object can be made from waste is no longer the hard part. The hard part is the production network, logistics, partnerships, data and return loops that let the same principle work many times over.

The largest test so far is Movares, where TRIBOO furnishes six offices on a ten-year subscription: 1,000 workstations plus other furniture, phone booths and meeting pods. The next proof points are practical: whether print farms in four countries turn out the same product from different feedstock, how returned PUZZL materials perform after a first cycle, and whether an architect can procure a complete circular interior through the new collective.

That is what makes the printer at MaterialDistrict in March a useful starting point. On the exhibition floor, it was a spectacle. Six months on, the more interesting story is the system being built around it.

Editorial note: the CO₂ figures come from third-party-verified LCAs, for Greengridz published as an EPD. Other figures and performance claims attributed to TRIBOO are taken from TRIBOO’s published material and data, and have not been independently verified by MaterialDistrict.
