“…HTT enables efficiently dewatering and upgrading of biomass wastes [18]. We have also verified that HTT can degrade the residual antibiotics in AMR and improve the dewaterability of AMR to allow its safe disposal and efficient production of solid biofuel [5,7,9,10]. Although HTT can partially remove nitrogen present in AMR [8],…”

The NO emission characteristics from both conventional and air-staged combustions of antibiotic mycelial residue were investigated in the temperature range of 1073 ~ 1273 K. The effect of hydrothermal treatment (HTT) prior to combustion on the NO emission was clarified. In conventional combustion, the NO emission from combustion of the hydrothermally pretreated antibiotic mycelial residue (HTT-AMR) was 20~30% lower than that from combustion of the directly dried antibiotic mycelial residue (Dried-AMR).

“…As the residues come from the fermentation processes, they are usually rich in moisture 3 existing mostly as bond water or water inside the mycelial cells [5,6]. Therefore, the incineration of AMR after efficient removal of moisture is anticipated to be the most feasible way for its innocent treatment and safe utilization [5,[7][8][9][10].…”

“…Certain types of substrate pretreatments also have a high impact on the gas yield. Recent studies showed that even 1.5–3 times higher methane output is possible than without pretreatment . While the available and used biogas yield data is from measurements on different biogas plants, taking these factors into consideration, the recent biogas installation of Hungary should be examined, but there is no available data about the type of plants being built; therefore, to eliminate these, the mathematical averages were used in every case.

m_{normalO normalD normalM} = m_{s} \cdot \frac{c_{\min} + c_{\max}}{2}

V_{b} = m_{normalO normalD normalM} \cdot \frac{K_{\min} + K_{\max}}{2}

V_{b} = n_{normalG normalV normalE} \cdot \frac{K_{\min} + K_{\max}}{2}

There are huge possibilities in using agricultural by-products for power or heat generation CHP, but this is still underdeveloped in Hungary. As the assessment of available capacities is an essential criterion of increased utilization, a method is provided to determine the biogas potential. The amount of available agricultural by-products to be used as substrate for biogas production in a Hungarian subregion is investigated as an example. The amount of biogas to be produced gives the theoretical potential from which the economic potential can also be estimated, taking into account the feasibility of certain types of biogas plants. The possibilities are shown through the example of a Central-Eastern European subregion with typical agricultural production. The biogas potential is calculated from the by-product generation of the agriculture, including both the farmers and large companies and unused arable lands as well. Although there are other possible biogas substrates available, such as sewage and communal waste, the goal is to determine how agriculture could participate in the energy production of the region, so these were not included in the calculation of biogas potential. The biogas could replace more than 35 million m 3 of natural gas, which is about 70% of the subregion's annual consumption or could be used to generate 123,692 MWh/a of electricity, which corresponds to 56% of the area's annual electricity consumption.

“…The pre-treatments in the presence of the catalyst showed an inhibition in the methanogenic activity due to high sulphate concentration, which, led to the growth of the sulphate reducing bacteria. Li et al [72], studied the hydrothermal pre-treatment on the methane production potential of antibiotic mycelial residue (AMR). Varying the treatment time from 0 to 60 min and temperature from 80 • C to 180 • C. The best digestion results were observed at a temperature of 120 • C for 60 min with a methane yield of 290 mL/g VS, which was almost 3 times the methane yield of raw AMR (100 mL/g VS).…”

Improvement of Anaerobic Digestion of Lignocellulosic Biomass by Hydrothermal Pretreatment

et al. 2019

Lignocellulosic biomass, comprising of cellulose, hemicellulose, and lignin, is a difficult-to-degrade substrate when subjected to anaerobic digestion. Hydrothermal pretreatment of lignocellulosic biomass could enhance the process performance by increasing the generation of methane, hydrogen, and bioethanol. The recalcitrants (furfurals, and 5-HMF) could be formed at high temperatures during hydrothermal pretreatment of lignocellulosic biomass, which may hinder the process performance. However, the detoxification process involving the use of genetically engineered microbes may be a promising option to reduce the toxic effects of inhibitors. The key challenge lies in the scaleup of the hydrothermal process, mainly due to necessity of upholding high temperature in sizeable reactors, which may demand high capital and operational costs. Thus, more efforts should be towards the techno-economic feasibility of hydrothermal pre-treatment at full scale.
