Microfiltered digestate to fertigation: A best practice to improve water and energy efficiency in the context of biogasdoneright™

Abstract

Biogasdoneright™ is an innovative agricultural model aimed at achieving a sustainable agricultural intensification. The microfiltration of the by-product from biogas production, the digestate, is among technology innovations supporting the implementation of best practices in the Biogasdoneright™ system. Digestate microfiltration tests were carried out under different operating conditions, to fine tune the best working conditions of the equipment. Then it was possible to distribute the microfiltered digestate in fertigation on growing maize through drip lines without causing blockage. Microfiltered digestate to fertigation has proven to be a best practice to improve nutrients, water and energy efficiency in the context of Biogasdoneright™.
