  First Boeing 777 with AeroSHARK takes off on passenger flights

  Copyright: astakhovyaroslav 15.11.2022 On October 14 for the first time, a Boeing 777-300ER operated by Swiss International Air Lines (SWISS) took off on a passenger flight with the AeroSHARK surface technology jointly developed by Lufthansa Technik and BASF. The fuselage and engine nacelles of the aircraft were recently fitted with approximately 950 square meters of so-called Riblet films, which replicate the flow-efficient properties of shark skin in order to reduce drag. Flow simulations have already identified a savings potential of just over one percent for this type of aircraft. The first scheduled flights with the aircraft registered as HB-JNH will now serve to validate this savings potential in daily flight operations. Thanks to its special surface structure of microscopic ribs - known as Riblets - AeroSHARK reduces the frictional resistance of this aircraft's outer skin by just over one percent, according to the calculations and flow simulations.

For this Boeing 777-300ER of SWISS, this would equate to annual savings of around 400 tons of kerosene and more than 1,200 tons of carbon dioxide. The AeroSHARK modification of the HB-JNH began at the end of August and culminated in several test flights on September 8 and 9. During these flights, it had to be demonstrated in detail that the AeroSHARK modification had no negative impact on the operational safety and handling of the Boeing 777. As soon as the calculated savings potential has been validated in actual flight operations, the full-scale roll-out at the launch customers SWISS and Lufthansa Cargo is planned to begin. Further Boeing 777s will then receive the AeroSHARK modification as part of regular maintenance layovers. Both airlines plan to have all their Boeing 777-300ERs and 777Fs successively fitted with AeroSHARK. This would make them the first passenger and cargo airlines worldwide to optimize a complete sub-fleet with this technology. When all of the current eleven Boeing 777s at Lufthansa Cargo and twelve at SWISS have received their AeroSHARK modification, they will reduce the Lufthansa Group's carbon footprint by more than 25,000 tons annually.

  Innovative technology makes flexible packaging recyclable

  Copyright: seventyfourimages 03.10.2022 They are indispensable in modern everyday life: Flexible packaging made from several layers of film enables the hygienic and safe storage of many foods. However, the versatile packaging has a problem: sustainable disposal. After use, the bonded films in the material mix are difficult to separate from one another - and that is why such flexible packaging is unfortunately only partially recyclable. Covestro has identified the problem - and has developed a process for recycling companies and packaging manufacturers to address this problem: In the case of multi-layer film packages laminated with polyurethane (PU) adhesive, the respective materials can be separated from one another again thanks to the new technology. The team will now present the development at the K 2022 trade fair from 19 to 26 October in Düsseldorf.

Since the separation agent consists of natural ingredients and water, it is also very sustainable. For packaging manufacturers and recyclers, the process offers a major advantage: "Our know-how helps them to make better use of the residual value of their packaging and thus makes more materials available to the recycling industry," says Thomas Fait. Flexible packaging made from several layers of film enables the hygienic and safe storage of many foods. But they face a problem: the disposal. At K 2022, Covestro will present a new process for separating the laminated films. This makes recycling possible; Copyright: Covestro The New Business Development Manager for Adhesives at Covestro has led the development of the technology on a laboratory scale. "With projects like this, we contribute to achieve our corporate vision: to make the circular economy a reality. For this purpose, we work with partners from a wide variety of fields and industries and are always looking for ways how our products and technologies can help other companies become circular." At the K 2022 trade fair, the team will be presenting the technology to the plastics industry for the first time and looking for potential partners from the packaging and recycling industry to further develop the process together with them.
