Use of Anaerobic Digestate from the USP Bioenergy Plant as Fertilizer

Short Introductive summary

On the USP Campus, located in the city of São Paulo, we have a Bioenergy and Biofertilizers Plant with an installed capacity of 75 kWe and is composed of a receiving unit, two 430 m3 bioreactors, a 430 m3 digestate tank, and a cogeneration unit. The digestate is a by-product and has potential to be used as a biofertilizer as it contains high concentrations of nutrients such as N, P, and K, among others, which can meet the nutritional demands of crops. The main objective of this work was to quantify the nutrients contained in the crude digestate and its separate phases by two different methods, decantation and centrifugation, to evaluate the digestate treatments. Throughout the article, will be presented the potential of digestate from bioenergy and biofertilizer Plant from USP to be used as biofertilizer.
