Innovative materials for sustainable luxury.

Mercedes-Benz is pursuing a holistic approach. With “Ambition 2039,” we are pursuing the goal of a fully networked and net carbon-neutral^[1]Net carbon-neutral means that carbon emissions that are not avoided or reduced at Mercedes-Benz are compensated for by certified offsetting projects.
fleet of new vehicles in 2039 – eleven years earlier than EU legislation stipulates. Special attention is being paid to the conscious and careful use of non-renewable as well as renewable resources. The company is working intensively on closing material cycles, significantly increasing the proportion of recycled materials in its vehicles and researching new materials that are in harmony with nature. A focus is on biotechnologically produced materials. They have enormous potential to replace petroleum-based materials as well as materials of animal origin.

Mercedes-Benz Research & Development has launched a technology challenge to achieve the company's sustainability goals. The aim is to minimize the environmental impact of all components and materials used. Everything is being put to the test in order to reduce carbon emissions, increase the use of recyclates and enable the circular economy. It is about the question of innovative concepts and new technological approaches. The Technology Challenge is designed to produce solutions that are as sustainable as possible for use in series production. Sustainability and luxury go hand in hand for Mercedes-Benz. This is demonstrated by two examples from current research and development that make use of biotechnology.

Mercedes-Benz pursues the goal of achieving more with less. To this end, the company is accelerating its pace of innovation and bringing new, sustainable technologies into series production as quickly as possible. An example from the VISION EQXX. Thus, material from UBQ™ is used in the sound generators of the EQA and EQB: It is obtained from the conversion of mixed household waste, which has been difficult to recycle so far, and is therefore often thermally processed or ends up in landfill. The material includes food waste, mixed plastics, cardboard, and baby nappies. Further applications of UBQ™ such as underbody panels, wheel arch linings and engine compartment covers are currently being tested.

Design for environment

At Mercedes-Benz, sustainability does not begin with automobile production, but rather in the early stages of product development. Mercedes-Benz calls this “Design for Environment”. The vehicle manufacturer takes a holistic approach to this, both in terms of the CO₂ emissions and the consumption of natural resources. Mercedes-Benz is increasingly relying on secondary materials and the use of renewable raw materials in its vehicles.

In vehicle development, the composition of all materials to be used is reconsidered and possibilities for more sustainable alternatives are examined. This applies to surface materials and to the materials that are not visible to the customer. Examples in vehicle interiors include the use of materials containing high levels of recycled elements and innovative materials of the future. In the body and body shell, Mercedes-Benz already uses CO₂ reduced steel in some model series, the production of which significantly reduces CO₂ emissions compared with classic blast furnace steelmaking. The company relies and focuses on innovative materials and technologies designed to meet Mercedes-Benz’s demands for luxury and sustainability.

The vehicle interior is an important part of the brand experience for customers. The highest visual and haptic quality are top priorities, along with comfort, functionality, and durability. Since the early days of the car, leather has been synonymous with high-quality interior features that many customers desire. Here, too, Mercedes‑Benz takes a holistic approach to making this luxury sustainable.

Vehicle interior: Sustainably processed leather

In the CLE and Maybach EQS SUV, Mercedes-Benz already offers sustainably produced and processed leather. This offering is also set to be extended to models of the upcoming vehicle platform. The consideration ranges from livestock breeding to the tanning process. Mercedes-Benz already requires compliance with various animal welfare criteria in its specifications. Among other things, the company requires its suppliers to comply with the Animal Welfare Committee’s “5 Freedoms Of Animal Welfare ” in livestock breeding. In addition, an important requirement Mercedes-Benz has in terms of supplier selection is that the leather supply chain must be free from any form of illegal deforestation and that grazing areas must not contribute to the endangerment or loss of natural forests. In this respect, partners must disclose their entire supply chain, from the farming region to the final product.

For a for a less environmentally damaging tanning process, only plant-based, organic mineral or, alternatively, sustainable tanning agents that are completely free of chromium — such as dried coffee bean husks, chestnuts, or extracts from other renewable raw materials — may be used to tan leather for Mercedes-Benz products in future. In addition, the leather for Mercedes-Benz products may only be processed in tanneries that are certified according to the Gold Standard of the ‘Leather Working Group’. This includes important environmental aspects such as reducing the use of water, energy, and chemicals in the tanning process. In addition, Mercedes-Benz works together with suppliers to continuously improve the sustainability of leather products. For this purpose, the partners are required, for example, to present a life cycle assessment of the entire value chain from the farm to the finished leather. In this way, targeted measures can be taken to reduce the ecological footprint of the leather.

Innovative materials: development of sustainable textiles and leather alternatives

At the same time, Mercedes-Benz is conducting intensive research into animal-free alternatives to genuine leather. They should not only conserve natural resources for future generations, but also offer the highest quality in all aspects. A promising material in research is a partially biotechnologically produced leather alternative. According to the mass balance approach, it consists of a unique combination of recycled plastic and bio-based materials. In a chemical recycling process, pyrolysis oil from used tires and certified biomethane from agricultural waste are produced and then processed into plastic fibers. These microfibers form a semi-finished product to which proteins and bio-based polymers are added. This results in an innovative material combination that is not only structurally similar to genuine leather but can also be further processed like genuine leather in post-tanning processes. As a result, it has the same high-quality appearance and feel, as well as natural aging properties. The material is breathable, waterproof, and lighter than genuine leather, and it has a reduced CO₂ footprint in direct comparison. Additionally, the portion based on recycled plastic can be fully recycled.

Mercedes-Benz offers various leather-free trim options in its vehicle interiors, including selected compact models such as the A-Class. These include a high-quality leather replica as well as a microfibre nonwoven fabric that consists of up to 73 percent recycled material. It is used in the vehicle interior on the seat cover, steering wheel, centre console and door panel. The proportion of recycled material will be continuously increased in future and the range of leather-free equipment is to be extended to other vehicle models. For us, the sustainability of the materials is fundamentally decisive.

Recycled materials are already in series production in many vehicles today. In the interior, for example, Mercedes-Benz offers various high quality upholstery fabrics made from up to 100 per cent recycled PET bottles, in addition to leather replica and microfibre. The floor coverings in the EQS use a nylon yarn that comes from recycled carpets and recycled fishing nets. In addition, Mercedes-Benz also relies on the use of natural fibres and textiles to replace conventional plastics with renewable raw materials.

In Group Research, the company is examining the series launch of promising new materials that meet Mercedes-Benz’s high standards of sustainability and quality. This includes a high-performance plastic with a painted surface obtained through innovative chemical recycling. In chemical recycling, used tyres and otherwise difficult-to-recycle plastic waste are broken down into their chemical components in such a way that entirely new materials can be produced from them. The combination of raw materials from chemical recycling with the renewable raw material biomethane reduces the use of fossil-based resources. Mercedes-Benz has already entered first components from chemical recycling into series production. Since 2022 the EQE and S-Class are the first series-production models which are available with bow door handles manufactured using a combination of biomethane and pyrolysis oil made from scrap tyres, instead of raw fossil resources. The S-Class will also come with a crash absorber based on this combination of raw materials. As part of the front end, the part creates a more even distribution of the forces acting on the other car in a frontal crash. Forthcoming models such as the EQE SUV will be equipped with bow door handles made from this innovative plastic as well. Looking to the future, the aim is to progressively increase the use of this more sustainable recycled material, and also to use chemical recycling in combination with the biomass balance approach for further plastic vehicle parts.

Another promising material that could be used in rear seat cushions is a partially CO₂ based foam. The main component of this automotive-grade polyurethane foam is polyol, and it chemically binds CO₂ which would otherwise be released into the atmosphere. By weight, the carbon dioxide can make up to 20 per cent of the polyol.

A focus in Mercedes-Benz research is on biotechnologically produced materials. The company is researching synthetic silk, which is produced using biotechnology and has the same functional properties as conventional silk. Genetically modified bacteria produce silk proteins. These proteins are refined into a shiny, silky yarn using a wet spinning process (known from cellulose production). The synthetic silk is 100 percent biodegradable, lightweight, and highly durable, making it an extremely high-performance material. Mercedes-Benz has already showcased initial applications for the novel silk in the VISION EQXX and the Concept CLA Class in the form of a door pull and a door pocket.

Before a material is used in series production in Mercedes-Benz vehicles, it must undergo a series of tests and intensive long-term trials. This ensures that it meets the company's high standards for quality and appearance. Surface materials, especially on seats, must have a certain structural integrity to prevent wrinkles, waves, and pressure marks. They must withstand temperature differences of around 100 degrees, direct sunlight, abrasion from denim fabrics, products like sunscreen and disinfectants, and sweat over a long period without becoming unstable, discoloring, or emitting odors. It is equally important that they are easy to clean, waterproof, and suitable for decorative stitching, embossing, and dyeing in different colors. Seat upholstery must also ensure good heat transfer for seat heating and good air permeability for ventilation.

A holistic sustainability assessment of all materials includes not only the vehicle interior but also the body and shell. Special attention is being paid to materials that are particularly CO₂ intensive in production, such as steel and aluminium.
