Use of an ultrasonic bath in the production of digestate extracts

  • 1 Kaunas University of Technology, Lithuania

Abstract

This study examines the potential of digestate, a byproduct of anaerobic digestion, in organic farming and its environmental implications. The EU produces around 180 million tons of digestate annually, mainly from agricultural sources. Renewable energy policies have promoted the use of biogas digestate. Analyzed the organic carbon concentration in digestate extracts using ultrasonic bath methods with water and potassium hydroxide solution. The study highlights factors influencing organic carbon concentration, including raw material origin, extraction time, temperature, and solvent type.
