The main environmental issue associated with the compost manufacture process is the production of a waste liquid leachate very complex in terms of composition. But, compost leachates may also be considered as a source of nutrients and can be converted to fertilizers. Physical and chemical properties were determined for a raw leachate from a mechanical biological treatment plant for municipal solid waste, to evaluate if it meets suitable requirements for using as commercial fertilizer according to the proposal of regulation of the European Parliament of 2016. So, this study intends to assess if the leachate can be used as a potential source for fertilizers. It qualitatively meets the requirements established for the composition of commercial fertilizers. Furthermore, the production costs of the leachate as a raw material are low since it is a waste effluent. Initial results showed low concentrations of some heavy metals and acceptable amounts of nutrients after concentration by batch distillation.
