Sustainability, Journal Year: 2025, Volume and Issue: 17(1), P. 321 - 321

Published: Jan. 3, 2025

Biogas is a renewable energy source that can be locally produced from the anaerobic digestion of several organic wastes, serving as partial substitute for natural gas derived non-renewable sources. This work provides an overview feedstock used biogas production, process, usage, and global Brazilian generation. In addition, potential output in Paraná State, Brazil was evaluated. Brazil, full biogas, especially within agricultural sector, has not been explored. Paraná, one Brazil’s leading producers, emerged prominent producer, particularly landfill industrial sources, primarily electricity According to findings this work, pig, chicken, confined cattle waste could generate 2.23 TWh electricity, equivalent approximately 8% state’s consumption. Moreover, biomethane surpasses 2021 production by 3.4 times. Based on results, significantly contribute sustainable generation, which would reduce greenhouse emissions promote cleaner more environmentally friendly matrix.

Spectral characteristics changes as affected by inoculating microbial agents during composting

Soil Research, Journal Year: 2025, Volume and Issue: 63(3)

Published: April 10, 2025

Context Microbial inoculations have become a key strategy to overcome the limitations of traditional composting (such as low microbial activity and degradation efficiency organic matter), attracting significant research interest. Aims This study aimed explore effect inoculation on spectral characteristics matter transformation during primary secondary fermentations. Methods Aerobic was carried out for 39 days compost samples at different stages were analyzed by UV-visible spectroscopy, Fourier transform infra-red spectroscopy (FTIR), X-ray diffraction (XRD). Key results The findings revealed that humification high polymerisation mainly occurred fermentation early fermentation, while degree decreased in late fermentation. facilitated oxidative decomposition fatty chains attached benzene rings stage leading formation functional groups such carbony1, carboxyl, hydroxyl, which promoted into humus. As progressed, carbohydrates, proteins, lignin, aliphatic compounds gradually decomposed, with an increase aromatic substances containing carbonate-containing rings. enhanced complete thus promoting humus effectively cellulose-like polysaccharide composting. Conclusions inoculum promote affecting physical chemical factors. Implications provides theoretical guidance optimising conditions, improving quality soil fertility.

Published: April 10, 2025

Rearing broiler chickens generates large quantities of waste material in the form bedding. Anaerobic digestion (AD) is a technology that can be applied to this waste. This study aimed evaluate AD litter, either screened (S) or unscreened (US), from different flocks, collected each production batch, totaling nine, commercial farm. was conducted batch biodigesters, and fraction separation performed through screening prior loading. The S substrate second fifth flocks did not produce biogas. Reductions total (TS) volatile solids were highest for substrates third flock (50.5% 58.3%, respectively). Only flock’s showed greater reductions than US substrates. Potential biogas methane also bedding both (336.8 218.2 L/kg TS, respectively) (296.8 213.4 concentration (64.8%), while substrate, it fourth (70.3%). Screening litter reduced process efficiency. We conclude inadvisable litter.

Abstract Residual antibiotics in chicken manure may interfere with the stability of anaerobic digestion (AD) and inhibit resource utilization efficiency. In this study, we aimed to enhance bio-methanation AD high-concentration sulfamethazine (SMZ) by adding metal (Fe, Co)-modified Enteromorpha -based hydrochar (Co-HC, Fe-HC). The results showed that Fe-HC Co-HC increased degree acidogenesis 1.25 times 1.58 times, respectively. maximum protein concentration EPS was 47.64% 72.5% after Co-HC. However, only demonstrated notable improvements both methane production SMZ removal Electrochemical analysis possessed a richer variety oxygen nitrogen functional groups, along superior electron exchange capabilities compared Fe-HC. Furthermore, microbiological assessments revealed enriched syntrophic bacteria (such as Syntrophomonas Mesotoga ), facilitating direct interspecies transfer (DIET) subsequently enhancing biomethane production. abundance genes involved significantly Co-HC, increase 75.86% Co1.5-HC treatment. Additionally, elimination antibiotic resistance ( sul1 , sul2 ) 65.66% This study offers theoretical foundation empirical support for synergistic improvement livestock poultry containing high concentrations, thereby helping overcome challenges posed recalcitrant substances.
