Resumo(s)
Leachate liquid streams originated from treatment plants contain carbon, nitrogen, phosphorus, potassium and trace elements. The present work aims to assess if a leachate, generated from a composting line of a mechanical and biological treatment facility, can be used as a potential source for liquid fertilizers, and thus propose and design a sequence of processes which could effectively convert the leachates to commercial liquid fertilizers according to the requirements of the proposal of regulation of the European Parliament of 2016 [1], [2]. The analysis shows that the leachate exhibits potential to be converted in an organo-mineral
fertilizer, since it exhibits high organic carbon content. However, some heavy metals and nitrogen and phosphorous nutrient contents do not fulfill the legislation requirements which implies a tuning of the liquid waste composition.
