Low carbon, environmental protection and green are the hot keywords of this year's Expo. Some foreign enterprises have recycled waste materials and made sustainable reuse products through relevant technologies.

At the Louis Vuitton booth, a bucket bag with LV logo on a blue background was thought to be denim from a distance, but when you look closer, you can find that it is made of felt material and a felt suit of the same type is placed beside it. According to the on-site staff, this material is jacquard cloth made of organic cotton and recycled wool, 100% recycled polyester fiber extracted from the existing inventory and recycled plastic for chains. The creation and use of sustainable and environmentally friendly materials in each product of felt series reflect its comprehensive consideration and challenge to creativity.

Cartier, in the same consumer goods exhibition hall, launched a new tank must watch this year. Coincidentally, it is also processed from waste. But from the appearance, we can't guess what material it is made of. After asking the staff, we know it is made of Apple waste. Compared with calf leather watch strap, the production process of the watch strap can save up to 10 liters of water resources, and the energy saved can complete about 200 smartphone charging, which is equivalent to saving 6 times of carbon emission.

In the sports goods exhibition area, Adidas displayed a hooded jacket called terrex myshelter Primaloft, equipped with 100% recycled fiber insulation. It is made of plastic waste from coastal and coastal areas. At the scene, the whole process of crushing, melting, spinning into yarn and finally making into clothes of recycled marine plastics was also vividly displayed to the audience.

At the kostron booth, the reporter found that they used triturn carbon dioxide technology to produce mattresses with carbon dioxide as the main raw material. It is reported that this technology can use carbon dioxide as a valuable alternative raw material for polyol production. Polyol and isocyanate can further synthesize polyurethane. Polyurethane can be used as memory cotton and used on mattresses to replace up to 20% of fossil based raw materials. Now, polyol raw materials based on this technology have been applied to many fields such as mattresses, sports floors, textile fibers and automobiles. At the same time, polyurethane can also be used as skin care products.
