The cover picture shows a view of the BASF site in Ludwigshafen, Germany; the largest and most highly integrated chemical site in the world. Integration, also called "Verbund," is the key success factor for sustainable chemistry. Ludwigshafen is also home to BASF's central research facility, where some of today's most efficient selective oxidation processes have been developed. One recent example is the new hydrogen peroxide to propylene oxide (HPPO) process shown in the inset. It was developed at BASF in a joint effort with Dow and is now the world's largest chemical process using H2O2 as oxidant. In their Review on page 508 F. Cavani and J. H. Teles critically assess the most recent developments in industrial oxidation processes.
