UTILISATION OF LIGNOCELLULOSIC BIOMASS FROM TOMATO PRODUCTION FOR ENERGY PURPOSES

Original language description

Lignocellulosic biomass (tomato shoots, stems, and leaves) is a relevant sustainable feedstock for methane digestion, but requires pretreatment. This is the effect of significant amounts of cellulose and hemicellulose surrounded by lignin, which is not digested by anaerobic microorganisms. The aim of the study was to develop an innovative technology to improve the biodegradation of lignocellulosic biomass from tomato production under methane digestion and pellet production (combustion). Thermomechanical pretreatment was performed in a single-screw extruder and granulator. The methane digestion process of extruded and unextruded biomass was carried out with daily measurements of the biogas yield and composition. The combustion of waste biomass pellets in a calorimetric bomb was also carried out to determine their calorific value. An energy balance of the extrusion and methane fermentation process was also made. The efficiency of pretreatment with optimisation of its parameters was evaluated. The main factors that influence the pretreatment of the lignin-cellulosic biomass were determined. The realisation of the proposed technological solution in the future will be cooperation with large greenhouse farms, which will allow implementation in practise.
