Maintenance – maintaining nature, life and ecosystems – is one of the mega-topics of our time. Too manyof us often waste what we have and throw away what we over-produce, and often there are too few whotake care to maintain what we already have or what we once had. Living sustainably can be a question ofmoney, and yet there are places in the world that are more sustainable than you would think: Did you know,for instance, that Ruanda doesn’t hand out plastic bags for free in supermarkets? Neither does Botswana.We all know that plastic ends up in the oceans and in fishes, birds and other animals which – fatally – mistakeit for their food. To save fishes and their natural surroundings, Sika Thailand took on a big challenge.Healthy coral reefs are plainly a sign of healthy oceans and hence of a healthy planet. But corals have beenseriously reduced in recent years: Extensive fishing and other forms of human encroachment have resultedin coral bleaching. Using cement and sand waste, Sika Thailand is producing cement cubes in which it isplanting coral fragments. The cubes are then placed on the seabed by divers to reafforest the coral reef.


At the same time, Sika Chile is maintaining good and healthy relations with its neighbors: It is supportingthe children at a nearby school by activating public green areas and developing other cooperationinitiatives with the school – such as guided tours of the laboratories.


Last but not least, this edition reports on the maintenance of reliable infrastructure for China’s growingpopulation and on the maintenance of art – and specifically an unforgettable piece of architecture,the Elbphilharmonie concert hall complex.


Yours sincerely
