Page 5: Introduction
1.2.1 Environmental Policy ABB is committed to its environmental policy. We strive continuously to make our products envi- ronmentally more sound by applying results obtained in recyclability and life cycle analyses. Prod- ucts, manufacturing process as well as logistics have been designed taking into account the envi- ronmental aspects. -
Page 6: Recycling The Transport Material
1.2.3 Recycling the Transport Material ABB designs all transport material to be recyclable where practical. The recycling of the transport material depends on the material type and availability of local recycling programs. After receiving the system into the site, the package and the transportation locking have to be removed. -
