With the goal of establishing an ecologi- cally and economically sound recycling sequence for decommissioned aircraft, Lufthansa Technik launched the project “2nd Life” in 2012. The background here is that repairing aircraft parts and storing replacement components is resource- intensive. However, decommissioned air- craft contain a myriad of valuable materials and parts that can be reconditioned and reused for maintenance and overhaul purposes once they have been recerti ed. This applies, for instance, when compo- nents in the active eet fail, their repair would lead to high costs or they would have to be sourced externally. In the reporting year alone, the MRO spe- cialist passed on four phased-out Boeing 747-400s from the Lufthansa Group to its subsidiary Lufthansa Technik Component Services (LTCS) in Tulsa, USA, for recycling. Since the start of the project, a total of 37 Lufthansa Group aircraft have been recy- cled via “2nd Life”. Depending on the type of aircraft, up to 1,000 components can be removed, including parts from landing gears, engines and auxiliary power units, cabin elements such as monitors and win- dows as well as instruments and data entry units in the cockpit. Which components are recycled depends on a number of factors, such as the consideration of which parts a particular aircraft was equipped with and the number of aircraft maintained by Lufthansa Technik that y with these sys- tems. Another important consideration is which parts are especially valuable, perhaps because they are no longer in production. In January 2014 and May 2015, the LSG Sky Chefs facilities in Detroit and Los Angeles both introduced a procedure that turns organic waste into water. The techno- logical basis is a closed decomposition system developed by EnviroPure that ac- celerates the natural decomposition pro- cess of organic waste. Provided there are optimum temperatures and suf cient oxy- gen, almost all types of organic waste can be decomposed in this way within 24 to 48 hours. The process works with the addition of a speci c biologically degradable addi- tive that supplies the bacteria naturally present in waste materials with comple- mentary micro nutrients. The result is a harmless liquid that can be discharged through the public sewer system. - “Zero Waste to Land ll” (ZLF) is a program that was launched in spring 2013 by LSG Sky Chefs at all 41 US locations to recycle 100 percent of its waste materials. At the end of 2015, the catering specialist achieved its ambitious goal. On December 31, the sum total of recycled waste materials reached 22,444 tonnes; for the program’s total duration this gure was 43,316 tonnes. Hans Bernd Schmidt Initiator of the “2nd Life” program Lufthansa Technik AG “With the project 2nd Life’ we have established an ecologically and economically sensible recy- cling circuit for decommissioned aircraft. Since the project’s launch, the Lufthansa Group has already recycled 37 phased-out aircraft in this way.” 56 // Climate and Environmental Responsibility
