This paper gives a short overview on the historical background and the formation of terra preta in the Amazon region. The composition of terra preta and the importance of charcoal and other ingredients for the formation and their carbon sequestration capacity are discussed. There is an outlook on how to recreate this very useful and nutrient rich type of earth in a synthetic way by mentioning current sources and studies.

The effects of lactic-aid conditions in urine-separation dry toilets and a subsequent treatment by vermicomposting are assessed. Research focused on analysing standard chemical and biochemical properties of the toilet products to evaluate their stability and maturity, and establish nutrient status.
