Économie circulaire L'économie circulaire est une expression générique désignant un concept économique qui s'inscrit dans le cadre du développement durable et s'inspirant notamment des notions d'économie verte, d’économie de l'usage ou de l'économie de la fonctionnalité, de l'économie de la performance et de l'écologie industrielle (laquelle veut que le déchet d'une industrie soit recyclé en matière première d'une autre industrie ou de la même).
Son objectif est de produire des biens et services tout en limitant fortement la consommation et le gaspillage des matières premières, et des sources d'énergies non renouvelables ;
Selon la fondation Ellen Mac Arthur (créée pour promouvoir l'économie circulaire1), il s'agit d'une économie industrielle qui est, à dessein ou par intention, réparatrice et dans laquelle les flux de matières sont de deux types bien séparés ; les nutriments biologiques, destinés à ré-entrer dans la biosphère en toute sécurité, et des intrants techniques ("technical nutrients"), conçus pour être recyclés en restant à haut niveau de qualité, sans entrer dans la biosphère

| Résumé : |
Borealis, Clariant, Remondis, LyondellBasell – many of the big names in the plastics industry announced partnerships with Neste at, or in advance of, K 2019. The Finnish company is a sought-after partner in the industry. Kunststoffe spoke to Mercedes Alonso, Executive Vice President for Renewable Polymers and Chemicals, about what the partnerships mean and which chemical recycling technologies are most promising. In the interview, she also revealed why Neste purchases food residues for plastics production. |
| Note de contenu : |
- Neste has been heavily involved in chemical recycling for some time. Can you give us an overview ?
- There are various chemical recycling processes in existence. What are you working on exactly ?
- What processes do you consider particularly promising ?
- What plastics wastes are primarily involved ?
- So you mainly deal with polyolefins ?
- Chemical recycling is usually presented as cmplementary, not as a competitor to mechanical recycling. Do you also see it that way ?
- Where do you currently see the greatest difficulties with chemical recycling ?
- With Remondis, you announced your intention to chemically recycle 200 000 metric tons a plastic waste per year so you don't just have theoretical considerations but specific projects
- What does the demand side look like ? Is there a particular interest in polyols from chemical recycling ?
- Chemical recycling is often met with a certain skepticism. For example, the EU does not recognize it for recycling quotas. Do you see that as a problem and do you expect if to change soon ?
- Besides chemical recycling, Nest is also working with bioplastics. You use waste fats and oils for this
- Where do these waste fats com from ?
- Neste produces about 3 million metric tons of diesel from vegetable oils and food residues. How high is your capacity for bio-based hydrocarbons for plastics ?
- Recently, you have entered into partnerships with Borealis, LyondellBasell and Clariant to produce bioplastics. What does this involve, exactly ?
- Are these long-term partnership or only one-off collaborations ?
- What is your collaboration with Clariant like ? |
