Closing cycles.

Nature knows no waste! In the Botanic Garden, a central nature protection facility, untold amounts of biological waste are produced every year and these were conventionally disposed of to date. Closing the material cycles in the Gardens is the aim of the TerraBoGa cooperation project. With the financial support of the European Union and the Federal State of Berlin, the biological waste is being examined with respect to recycling it and, in accordance with the Garden’s needs, is being prepared using methods that were originally modelled on Terra Preta from the Amazon region in Brazil.
