The main material groups at König + Neurath are steel, wood and wood derivatives, plastics and aluminium.
Steel is used for instance in desk and cupboard frames, chair mechanisms and metal shelves. Visible steel parts are protected by solvent-free powder-based lacquers. This also enables a wide colour choice.
Aluminium is significantly lighter than steel and can be formed easily. Because of its properties it is often used for instance for profiles in free-standing dividers and desktop screens. We also use it in the construction of room systems and in the form of cast aluminium in starbases for chairs. In our cast aluminium parts, 100% of the aluminium comes from secondary sources. This means it is 100% recycled material. When recycled aluminium is used, the energy requirement is up to 95% lower than with the standard light metal extraction method from ore.
For extruded aluminium profiles, König + Neurath has opted for Hydro REDUXA. This is an aluminium with considerably lower carbon emissions compared with the European average, specifically a maximum of 4.0 kg CO₂/kg aluminium. An externally verified EPD - Environmental Product Declaration confirms the correctness of this statistic).
Wood and wood-based materials
König + Neurath has a high throughput of wood and wood-based materials. It is used for instance in work surfaces, cupboard, pedestal and sidefiler carcasses, and as wooden bases for visitor chairs. We have agreed with our wood derivatives suppliers that we will only accept chipboard containing wood from sustainable forestry. In doing so we ensure that around three quarters of all wood we buy originates from sustainable sources.
We set high standards for textiles before approving them for inclusion in the König + Neurath fabric – collection. Our collection only features fabrics that are certified in accordance with OEKO-TEX® STANDARD 100, EU Ecolabel, GREENGUARD Gold, Cradle to Cradle® and Indoor Advantage™ Gold. The leather in fabric group 50 carries the Blue Angel certification.
The use of recyclate and recycling potential at the end of the product life cycle
Our product developers constantly evaluate whether it is possible to use recyclates. Recyclates are materials that have been used before and have become waste from either the industry process or the consumer. Whether recyclates can be used is decided on the basis of the static and aesthetic requirements of the product, as well as its assured availability on the market long-term. We aim to use as high a proportion of recyclates as possible in our products, as long as we can do so without compromising product quality. Information about the proportion of recyclates in the products can be found in the K+N environment certificates, which are available from the media database.
At the end of the product lifecycle, when recycling is the only option left, our products are easy to dismantle and therefore mostly recyclable. To make dismantling easier, König + Neurath provides dismantling instructions for its main products. The idea is to make it easier to separate according to material type and recycle the individual materials.
