Acquisition of Torrefied Biomass from Jerusalem Artichoke Grown in a Closed Circular System Using Biogas Plant Waste

Abstract

The aim of the research was to investigate the effect of biogas plant waste on the physiological activity, growth, and yield of Jerusalem artichoke and the energetic usefulness of the biomass obtained in this way after the torrefaction process. The use of waste from corn grain biodigestion to methane as a biofertilizer, used alone or supplemented with Apol-humus and Stymjod, caused increased the physiological activity, growth, and yield of Jerusalem artichoke plants and can limit the application of chemical fertilizers, whose production and use in agriculture is harmful for the environment. The experiment, using different equipment, exhibited the high potential of Jerusalem artichoke fertilized by the methods elaborated as a carbonized solid biofuel after the torrefaction process. The use of a special design of the batch reactor using nitrogen, Thermogravimetric analysis, Differential thermal analysis, and Fourier-transform infrared spectroscopy and combustion of Jerusalem artichoke using TG-MS showed a thermo-chemical conversion mass loss on a level of 30% with energy loss (torgas) on a level of 10%. Compared to research results on other energy crops and straw biomass, the isothermal temperature of 245 °C during torrefaction for the carbonized solid biofuel of Jerusalem artichoke biomass fertilized with biogas plant waste is relativlely low. An SEM-EDS analysis of ash from carbonized Jerusalem artichoke after torrefaction was performed after its combustion.

Sustainable Drying and Torrefaction Processes of Miscanthus for Use as a Pelletized Solid Biofuel and Biocarbon-Carrier for Fertilizers

“…At (300 °C, 6 min) there was observed closest to 50% mass loss which according to the literature is one of the most optimal mass loss for the biochar production as additive/carrier of C for fertilizers. At (525 °C, 5 min) the mass loss was closest to 75% mass loss which from the process and it economic point of view is reasonable temperature for the production of biosorbents/activated carbons [ 98 , 99 ]. It can be also added that this can impact the bio economy by the fact that an optimal mass loss ratio to energy loss for different energy crops during the torrefaction process has a significant impact on both carbonized solid biofuel and biochar as carriers for fertilizer prices (too much or too little heat for the process has a significant impact on the final product prices) [ 100 ].…”

Obtaining Granules from Waste Tannery Shavings and Mineral Additives by Wet Pulp Granulation

“…The compatibility of protein hydrolysate with many other chemical materials (bentonite, dolomite, kaolin) increased absorption at leaf level, and biodegradability paves the way for toxicity reduction and plant health stimulation [ 54 , 55 , 56 , 57 ]. Protein hydrolyzes from tanning waste can induce plant defense responses and increase the plant’s tolerance to various abiotic stresses (salinity, drought, temperature, and oxidizing conditions) [ 58 , 59 ]. The investigation in this article constitutes a multi-stage cycle of research in the field of recycling and reusing waste generated by tanneries.…”

Change in Mixing Power of a Two-PBT Impeller When Emptying a Tank

“…Thus, an increase in mixing power only occurs with the axial action impeller. PIV methods that were used in this research are also widely used in different applications as in designing heat exchangers [42,43] and dryers [44][45][46][47][48].…”
