Recently, Audi Auto officially released the seat preview of the new Audi A3, and said that the seats of the new car will be made of recycled materials, which also set off a discussion on environmentally friendly materials. In fact, with the enhancement of environmental awareness, people are more and more willing to accept the use of recycled materials, and many automobile manufacturers have also started research in this area, so the recycled materials on the new A3 are nothing new! Today, the author will take you to have a brief understanding.

First of all, let's briefly introduce what is recycled material, which refers to all raw materials that can be recycled in industry and reused after a certain processing process. According to different materials, there are many kinds of recycled materials, among which plastic recycled materials are the most. Recycled plastic particles are classified according to the different raw materials used and the characteristics of recycled plastic particles produced by processing, and are generally divided into primary recycled plastic particles, secondary recycled plastic particles and tertiary recycled plastic particles.

Audi A3

The parts of the new A3 made of renewable materials are seats and foot pads. For example, 89% of textiles on seats are recycled PET plastic bottles, which are processed into yarns. Each seat can use up to 45 PET plastic bottles with a capacity of 1.5 liter. In addition, the carpet of the new Audi A3 is made of 62 pet plastic bottles. Both appearance and texture can reach the same quality standard as traditional textile interior decoration. In addition, more and more auxiliary materials are used for other internal components, such as thermal insulation materials, trunk side decorative panels, trunk mat, etc.

Headquartered in Sweden)

Volvo announced its plan for renewable materials as early as 20 18, and said that at least 25% of the plastics used in all new cars of Volvo will come from renewable materials from 2025. To demonstrate the feasibility of the plan, Volvo released a brand-new XC60 in Gothenburg, Sweden. T8 plug-in test vehicle. The appearance of the new car is the same as the current model, but several plastic parts are replaced by renewable plastics. Specifically, the center console of the test vehicle is made of recycled fibers and plastics from discarded fishing nets and navigation cables, the carpet contains fibers made from pet (polyethylene terephthalate) plastic bottles, and renewable blended cotton materials from garment manufacturers' scraps, and the seats also use PET fibers from plastic bottles. In addition, the new car also uses the old seats on other Volvo cars to make sound insulation materials under the hood.

Jaguar Land Rover

Last year, Jaguar Land Rover cooperated with German chemical giant BASF to test a new renewable material, which will be applied to the front bracket of Jaguar I-PACE prototype, but at present, the material is still in the testing stage to see if it can meet the strict assembly safety requirements.

Bmw BMWX3

Previously, Geiger (geiger? Automotive) announced that it will choose Ravago's regeneration Mafill? CR？ HT？ 5344? H material, for BMW? X3 Manufacturing cooling air inlet components. Mafill？ CR？ HT？ 5344? H is Ravago's first recycled polypropylene (PP) product with global uniform specifications, which can provide the same quality whether produced with raw materials provided by Europe or the United States.

Ford

In addition, Ford Motor Company has done its best in environmental protection, reducing its carbon footprint by recycling plastic bottles and using them to manufacture auto parts. Car manufacturers use an average of 300 recycled bottles per car, which is equivalent to about 65.438+0.2 billion plastic bottles per year. It is used to manufacture the underbody of all cars and SUVs, as well as the tire lining of F-series trucks.

Ford said that recycled plastic is an ideal choice for auto parts, because it is light and can improve the aerodynamic performance of vehicles. According to Ford, better aerodynamics will be improved by 2020? Ford? Escape saves fuel and provides a quieter driving environment. In addition, Thomas, a design engineer at Ford Motor Company? Sweder said in a statement, "The underbody is a very large part. If we use strong plastic, its weight may increase by three times. " So renewable plastics are a better choice. They are lighter. Recyclers cut bottles into small pieces and sell them to suppliers, who make them into fibers for making plastic sheets. Then, Ford used these steel plates to make the body floor. Innovative plastic recycling and reuse has positive economic and environmental significance.

guiding principle

Polestar is a car brand jointly built by Geely and Volvo, and it also inherits Volvo's environmental protection attributes. In addition to the pure electric vehicle itself, it also uses environmentally friendly and renewable materials as far as possible in its internal materials. For example, Polestar's seats are prepared to use 3D knitted fabrics to reduce waste and simplify the handling of material sources. In the process of making components, single yarn is used, and the main material is 100% recycled yarn obtained from PET bottles.
