Conditioning Biomass for Biogas Plants: Innovative Pre-Treatment and Digestate Valorization Techniques to Enhance Soil Health and Fertility

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3289 - 3289

Published: April 8, 2025

In line with the concept of sustainable agriculture, efforts should be made to increase green energy yield and minimize environmental impact mineral fertilizers, maintaining high agricultural productivity. alignment principles development, plant biomass-based is considered promising. A deep understanding enhancements anaerobic digestion process using biomass, along digestate post-treatment for regenerative agriculture improvements, are key elements achieve sustainability goals. This article describes innovative methods biomass pre-treatment aimed at enhancing biogas fertilizing potential obtained digestate. Moreover, valuable insights into conditioning valorization discussed. Among these, separation stabilization techniques emphasized. Furthermore, this provides a comprehensive source knowledge on soil quality, fertility, organic carbon sequestration, microbiota. The findings contribute broader how impacts agriculture.

Growth Dynamics and Nutrient Removal from Biogas Slurry Using Water Hyacinth

Sustainability, Journal Year: 2024, Volume and Issue: 16(11), P. 4450 - 4450

Published: May 24, 2024

Aquatic macrophytes, notably the invasive water hyacinth, exhibit proficiency in nutrient removal from polluted bodies, rendering them appealing for remediation applications. This study investigates potential of hyacinth phytoremediation, focusing on effect using nutrient-rich biogas slurry mixed with varying concentrations, i.e., 16.6, 33, 66.6, 100, and 133 mg/L investigation. The physiochemical properties liquid were evaluated before after treatment over eight weeks, continuous monitoring reduction rates. Results showcased substantial average reductions nitrogen, phosphorus, potassium, a relative growth rate 5.55%. also decreased pH, total dissolved solids, hardness, chemical oxygen demand. theoretical BMP was determined Buswell’s equation. Water grown concentration exhibited highest methane yield at 199 mL CH4/gm VS, along rate. used experimental data to create mathematical model that describes how depends number days (C). model’s quality effectiveness goodness fit (R2) observable approaches. polynomial model, referred as Poly 1, 2, is best describing relationship between percentage days, solution concentration. In this C has degree one (normalized mean 69.84 ± 43.54), while D two 30 21.65).

Enhancing Biogas Production Through the Co-Digestion of Fish Waste (FW) and Water Hyacinth (WH) Using Cow Dung as an Inoculum: Effect of FW/WH Ratio

Applied Sciences, Journal Year: 2024, Volume and Issue: 14(21), P. 9880 - 9880

Published: Oct. 29, 2024

The current investigation explores biogas production from water hyacinth (WH) and fish waste (FW) with cow dung (CD) as an inoculum source in two scenarios. In the first scenario, optimization of mono-digestion was performed where effect WH/FW (substrates) CD (inoculum) varied ratios 1:1, 1:2, 2:1, 3:1 observed to enhance production. second co-digestion using both FW WH substrates different (1:1, 2:1) a fixed amount studied. experiments were conducted 500 mL digesters duplicate under mesophilic conditions. Under conditions for FW, digester operating FW/CD 1:2 ratio demonstrated highest yield 970 ± 14.1 mL/g VS, containing 610 CH4 while WH, WH/CD 1:1 exhibited 925 49.4 methane content 440 VS. (1:1) showcased 1655 91.92 accompanied by 890 70.7 This followed 2:1 ratio, yielding 1400 56.5 1140 169.7 775 585 respectively. mixture at most significant decrease chemical oxygen demand (COD), reaching 91.68%. COD reductions over 80% all combinations instances. Anaerobic digestion (AD) simulations validated Gompertz model, high correlation coefficient values (R-squared) above 0.99 studied ratios, depicting between experimental data model predictions. propionic acetic acid did not cross threshold level, indicating no inhibition ANOVA analysis showed non-significant results (p > 0.310 p 0.824, respectively), overall < 0.024), efficiency variations among substrates. Paired sample t-tests revealed substantial differences which also significant.
