How do we eco-design? Why do we do it? What processes can we use?
Using these recycled polyester filaments enables us to reduce the CO2 emissions linked to the production of the yarn by at least 16% compared to using virgin polyester.
Why this choice? The carbon impact of raw materials represents one of the major parts of the environmental footprint of the product, according to the latest data available to us.
The plastic bottles are cleaned and shredded into flakes. These are then poured and melted, turning into a paste. The paste is transformed into filament thanks to an extrusion screw. This filament is then spun around a reel, creating the recycled polyester thread!
Using this dyeing process in the mass enables us to reduce the CO2 emissions linked to the production of the dyed textile by at least 46% compared to conventional dyeing.
Why work on dyeing? Because this stage in the production process is a major part of the product's environmental footprint.
To produce thread required for manufacturing fabric, we place polyester, in paste form, into a barrel. Equipped with a very narrow hole at its extremity, an endless screw (called an extrusion screw) forces the material to come out of the barrel in a thin filament.
At the same time as the polyester paste, we insert colour pigments in powder form. So when extruding the yarn, it comes out coloured and ready to use for designing our products.
Using these recycled cotton fibres enables us to reduce the CO2 emissions linked to the production of the thread by at least 21% compared to using virgin cotton.
Why this choice? According to the latest data available to us, the carbon impact of raw materials represents a major part of the environmental footprint of a product.
We recycle cotton from our production waste to reduce our waste and the use of virgin cotton. We extract the fibres to form a new thread. However the share of recycled cotton in a product can only be a maximum of 40% because recycled fibres are too short and have to be combined with new fibres.
By using organically grown cotton fibres, we can reduce the CO2 emissions linked to the production of the thread by at least 2.4% compared to the use of conventional cotton.
Organic cotton is grown with seeds that are free of GMOs (Genetically Modified Organisms) and without the use of pesticides whilst the crops are growing. Instead, farmers use natural fertilisers on the land and natural pest control to repel harmful insects.
Using these recycled polyester filaments enables us to reduce the CO2 emissions linked to the production of the yarn by at least 16% compared to using virgin polyester.
We collect plastics from production waste and end-of-life materials to recycle them. This involves shredding them into small pieces and melting them into a paste. Once in paste form, it is possible to inject it into a mould of the desired shape.
You may have already noticed it on our website: our products' carbon footprint is now available on each and everyone one of them.
What does that mean? What and for who is it of use? How do we go about it?
Don't move, and we'll explain everything on this page! It's because, at DECATHLON, we design our products that it's possible for us to be one of the only companies to be able to share specific data about their carbon footprint.
