+ | Cradle to Cradle® carpet company Desso launches new circular economy material stream of up to 20,000 tonnes of chalk from local water companies | ||
+ | |||
+ | In a bold new move on the transformational journey to the circular economy, Desso, a leading global carpets and sports pitches company has developed a new material stream for its carpet tiles based on a partnership with a group of drinking water companies in the Netherlands. | ||
+ | |||
+ | As a Cradle to Cradle® company, Desso is committed to developing products that can be brought back and recycled in a non-toxic closed loop, the foundation for a regenerative circular economy. Through a rigid C2C assessment process, Desso strives to ensure its products consist of healthy materials, positive for human health and for the planet. The company vision is to develop environmentally responsible products that contribute to health and wellbeing in the built environment. This commitment to material health ensures that Desso realises this vision while its goods are in use and when they are being recycled. | ||
+ | |||
+ | In collaboration with Reststoffenunie, an association of drinking water companies in the Netherlands, Desso has found a way to upcycle re-engineered calcium carbonate (chalk) from local drinking water companies such as Brabant Water and WML (Water Maatschappij Limburg). The chalk is positively defined[1] in accordance with C2C criteria and is used for the production of Desso's carpet tiles with EcoBase™ backing, which is C2C Silver certified and 100% recyclable in Desso’s own production process. | ||
+ | |||
+ | The result of this new innovation is that Desso’s products with EcoBase™ backing will now contain on average 50% positively defined recycled content. | ||
+ | |||
+ | “This new development is a hugely exciting step forward in our vision to become a Cradle to Cradle® company developing products that meet high standards of creativity, functionality and are also positive to human health and the planet,” says Alexander Collot d’Escury, CEO of Desso. | ||
+ | Guïljo van Nuland, CEO of Brabant Water says: “The concept of recycling our waste as a material stream for Desso’s process fits perfectly with our status as the first climate-neutral drinking water company in Europe.” He added, “We are proud that our calcium granules contribute so positively to Desso’s Cradle to Cradle® carpet tiles.” | ||
+ | |||
+ | And Ria Doedel, CEO of WML, says: “More than 99% of our waste materials, especially iron and calcium, is now recycled. The innovations in this area are increasing and sometimes surprising. Our co-operation with Desso is a great example of this.” | ||
+ | |||
+ | Desso is the first carpet company in the world to use the upcycled calcium carbonate (chalk)[2], co-created by Desso’s R&D team and its partners in the water industry. It expects to draw as much as 20,000 tonnes of chalk from this circular economy waste stream for its carpet tiles in partnership with the Dutch water companies. Desso has also launched its new Transitions collection with this positively defined recycled content. | ||
+ | |||
+ | According to recent research the circular economy in total could generate one trillion dollars a year in cost savings globally[3] through a smarter use of material streams. | ||
+ | Desso is a member of the collaborative network, the Circular Economy 100[4], organised by the Ellen MacArthur Foundation and Desso’s CEO Alexander Collot d’Escury is a member of the steering committee of Project MainStream[5], a cross industry circular economy project organised by the World Economic Forum and the Ellen MacArthur Foundation. | ||
+ | |||
+ | “In Cradle to Cradle® philosophy, consistent and positively defined material streams are treated as nutrients for the technological or biological spheres,” says Ludwig Cammaert, Desso’s chief of R&D. “Our first task was to design the DESSO EcoBase® carpet tiles so that they could be disassembled when taken back in the post-consumer stage.” | ||
+ | |||
+ | The next stage was to look for new circular innovations, adds Cammaert. “We are always looking for ways to utilise consistent waste streams as a nutrient for the production of our carpet tiles today.” | ||
+ | |||
+ | In this case, he adds, R&D at Desso spotted along with its partners a way to use material streams from the drinking water industry, a completely different sector. The drinking water process leaves a residual of calcium carbonate after it has softened groundwater, a necessary step to make it suitable for drinking. In addition, soft water increases the life span of home appliances, as it reduces chalk deposits and therefore requires less cleaning. | ||
+ | “We had some challenges, but with the strong commitment and support of all the partners we were able to overcome them,” Cammaert adds. “Also with the help of Sibelco, an advanced global industrial minerals supplier, the calcium carbonate particle size and particle size distribution was tailored to Desso’s requirements, making this a true innovation in the value chain process.” | ||
+ | |||
+ | The process utilises a material stream that might otherwise have ended up in less valuable outlets; and by sourcing and processing this material stream locally, Desso and its partners could ensure it had a positive impact on the environment, and demonstrate perfectly how circular economy thinking can be brought into practice driven by Cradle to Cradle® principles. | ||

Le cradle to cradle
Cradle to cradle = du berceau au berceau
Le cradle to cradle à la base de l'économie circulaire
Cradle to cradle = du berceau au berceau
- Le best-seller Cradle to Cradle est enfin traduit en français. Publié pour la première fois en 2002, l'ouvrage du chimiste allemand Michael Braungart et de l'architecte américain William McDonough a d'ores et déjà séduit 50 millions de lecteurs aux quatre coins du globe. Traduit dans plus de vingt langues, il arrive cette semaine dans les rayons des librairies françaises.
Le concept de ces pionniers de l'écologie industrielle « nouvelle génération » peut se résumer ainsi : rien n'est déchet, tout est nutriment. Autrement dit, le Cradle to Cradle (littéralement, « du berceau au berceau »), est un processus « qui met en œuvre à la fois l'analyse chimique des éléments à utiliser et un système social fondé sur la restitution », dixit Michael Braungart en introduction de son ouvrage. Une philosophie que les deux auteurs tentent de diffuser auprès des industriels du monde entier, notamment via leur laboratoire hollandais Environmental Protection and Encouragement Agency (EPEA).
Un réseau Cradle to Cradle
- Les entreprises converties au C to C ne parlent d'ailleurs plus de « cycle de vie » d'un produit, mais bien de « cycle d'usage ». Car une fois sa phase d'utilisation terminée, un produit C to C doit être facilement démontable, et ses composants, réutilisables à l'infini. Sur le papier, l'idée est forcément séduisante. Mais garantir un usage circulaire des produits industriels suppose une implication des entreprises et une collaboration inter-sectorielle inédites.
« Il s'agit de maîtriser parfaitement la toxicité et l'empreinte écologique des matériaux, de revoir la conception des produits, pour qu'ils soient aisément montables et démontables, de garantir leur reprise en fin d'usage et de mettre en place des filières de recyclages spécifiques », témoigne Hélène Babok, directrice développement durable de Steelcase France. Le fabricant international de mobilier de bureaux a été parmi les premiers à engager une stratégie globale Cradle to Cradle. Et si une cinquantaine de ses produits certifiés C to C sont déjà sur le marché, la généralisation du processus à l'ensemble de sa gamme reste un travail de longue haleine. « Nous rencontrons quelques difficultés à récupérer des données toxicologiques auprès de nos fournisseurs, ajoute Hélène Babok.
Car certains produits, comme un siège de travail par exemple, comptent plus de 150 composants, et chacun de ces composants peut faire intervenir jusqu'à 60 substances chimiques. Par ailleurs, la fabrication de ce siège fait intervenir une quarantaine de fournisseurs environ, qui eux mêmes collaborent avec nombre de fournisseurs.» La mise en place de filières de collecte et de recyclage suppose quant à elle d'établir des partenariats, notamment pour en supporter le coût économique. Spécialisé dans la collecte et le traitement des déchets, le groupe hollandais Van Gansewinkel, qui se définit également comme fournisseur de matière première et d'énergie, travaille ainsi avec plusieurs partenaires Cradle to Cradle (Phillips, Van Houtum Papier, le fabricant de moquettes Desso, etc.) pour boucler la chaîne de vie des produits. De l'avis de tous, le sourcing des données est à améliorer et le partage d'expérience à encourager. « Nous sommes dans un processus d'amélioration continue » résume Hélène Babok.
Le Cradle to Cradle séduira-t-il les français ?
Le processus a cependant du mal à passer les frontières françaises. Certes, Steelcase, Herman Miller, Van Gansewinkel, Desso et quelques autres pionniers diffusent le concept, insufflé par leurs maisons mères, via leurs filiales françaises. Mais le Cradle to Cradle est encore loin de rencontrer le succès qu'il connait par exemple en Hollande. Là-bas, 200 entreprises sont converties au C to C, le ministère de l'environnement élabore une stratégie d'approvisionnement pour les organisations gouvernementales, 40% des profits du commerce gazier ont été alloués à la R&D du Cradle to Cradle, et un master dédié au concept est en passe d'être proposé à l'Université de Rotterdam. Pourtant, de l'aveu même de Michael Braungart, « la traduction française a été difficile à réaliser. »
Alors comment expliquer ce retard français ? Pour Eric Allodi, directeur d'Intgéral Vision, société de conseil chargé de promouvoir le C to C, « la France, pays des Lumières et du rationalisme, n'est pas encore entrée dans l'ère post-moderne, contrairement aux pays d'Europe du Nord. Dans ces pays, les gens se revendiquent davantage citoyen du monde que citoyens d'une nation. Or, cette mentalité est plus propice au déploiement du Cradle to Cradle, qui suppose une vision globale et une volonté de changer de paradigme. »
Pour l'heure, Intégral Vision travaille avec trois sociétés françaises, dont Dim, qui d'après Eric Allodi a lancé un programme de recherche pour développer un collant to C (Dim refuse encore de communiquer sur ce projet), et Tarkett, leader mondial du revêtement de sol et surfaces sportives, qui vient d'annoncer son partenariat avec EPEA. « Le Cradle to Cradle est une source d'innovation, assure Anne-Christine Ayed, chargée de la recherche, de l'innovation et de l'environnement chez Tarkett. Plus les entreprises s'engageront dans cette démarche, plus les citoyens se mobiliseront. » Un appel qui sera entendu ?
