Resumo:

It exposes the problem of pruning from the perspective of waste management, that is, from the point of view of an institution responsible for urban cleaning in a large city. In Rio de Janeiro, there are more than 600,000 “public” trees, and their pruning and the removal of branches and roots of fallen trees due to strong winds or even by degradation of the individual is an immense work that few know about. Teams of trained and formed professionals are required, as well as a lot of equipment. In addition, in public institutions, political pressure is unimaginable, which occurs mainly on the part of city councilors, so that the agency responsible for pruning meets their requests with priority. This service is an invaluable means of political bargaining that few know about. In addition, it is difficult to meet all these demands. Some want the trees to be pruned leaving only their trunk; others want the plants not to be touched. Anyway, it is a demanding and expensive activity that I can discuss in the time that I will have at the congress. Let us say that this is not a very scientific or botanical view, but a more pragmatic one, which also includes the best uses that the COMLURB tries to give to waste: composting, fuel for ceramics, biomethanization, public furniture manufacturing, etc.
