The objective of this article is to investigate the integration a digestate treatment with biogas plant processing sewage sludge and food waste via process simulations: co-HTC mixed digestates supercritical water gasification (SCWG) aqueous effluent. optimum conditions are selected based on energetic yields, comparing relative equipment sizes besides hydrochar product. 200 °C, 30 % solid load, 1-h residence time for mixing ratios in scope: yields 3.58–3.59 MJ/kg reactor inlet. These result more than 60 K, P, N recovery hydrochar. SCWG effluent provides complete mineral form surplus energy production through syngas while causing some nitrogen loss as N2 gas. Although data calculated from individual HTC results, synergetic effect yield does not affect selection investigated (the origins digestates). Consequently, plants can evolve into multi-product biorefineries proposed integration. Meanwhile, study guide future experiments reduce required runs.

In this study, the agricultural digestate from anaerobic biogas production mixed with food wastes was used as a substrate to grow Trichoderma reesei RUT-C30 and atroviride Ta13 in solid-state fermentation (SSF) produce high-value bioproducts, such bioactive molecules be ingredients for biostimulants. The spp. reached their maximum growth after 6 3 SSF days, respectively. Both species were able cellulase, esterase, citric malic acids, while T. also produced gibberellins oxylipins shown by ultraperformance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) profiling. Experimental evaluation of germination parameters highlighted significant promotion tomato seed root elongation induced crude extracts SSF. This study suggests an innovative sustainable use whole agro-food waste valuable fungal biorefineries. Here, it has been applied plant growth-promoting fungi agriculture.

Anaerobic digestion (AD) is widely used for the sustainable treatment of biological wastes and production biogas. Its byproduct, digestate, a valuable organic waste needs appropriate management, which one major concerns with negative impact on efficiency biogas installations. One approach to extend utilization digestate as well improve its handling storage characteristics compaction into pellets. This study aimed evaluate behavior during cyclic loading unloading in closed matrix. The findings presented here may provide insights mechanisms pellet formation optimizing pellets improving their management. can be considered novel it applied loading, first time, view densification modeling pelleting prediction.

Exploring Cutting‐Edge Approaches in Anaerobic Digestion and Anaerobic Digestate Management

ChemBioEng Reviews, Год журнала: 2024, Номер 11(3), С. 573 - 594

Опубликована: Май 3, 2024

Abstract Exploring alternative energy sources is vital amid increasing human fuel consumption. Globally, biogas, rich in methane, hydrogen sulfide, and carbon dioxide, addresses demands through biomass anaerobic digestion (AD). Efficient digestate management, employing techniques like solid‐liquid separation composting, crucial for environmental protection. The goal to optimize nutrient‐rich byproduct utilization while minimizing negative impacts. This review analyzes diverse substrates, emphasizing challenges benefits. Key considerations include nutrient ratios, moisture content, co‐digestion, organic loading rate, retention time. study explores temperature's impact on microbial growth, biogas impurities, upgradation techniques, including biological methods. Fermentation, electrochemical biochar use enhanced AD are introduced. Discussing digestate's multifaceted aspects, the highlights its value applications aquaculture, animal feed, fermentation, bioremediation, fine chemical production.
