Addressing the agricultural challenges of agri-food waste accumulation, this study assessed energy potential green residues from tomato (Solanum lycopersicum L. cv. Kmicic) plants in different fertilizer configurations and Shea nutshell (Vitellaria paradoxa) waste. Two key parameters were compared: (I) Calorific Value (CV), representing thermal treatment, (II) Biogas Biomethane production potential, biochemical treatment. Potential was estimated using Baserga method fermentable organic matter (FOM) method. Additionally, effect fertilization on elemental composition its analyzed. showed better properties for both utilization, with a CV 16.29 MJ/kg. The FOM methods estimation that highest yields 504.18 671.39 LN/kg DM, respectively. Among fertilized residues, volcanic tuff additive resulted an optimal C/N ratio (28.41) high 457.13 DM (Baserga) 542.85 (FOM). These findings demonstrate feasibility employing as promising feedstock production.

In order to study the effect of cotton stalk particle size on humification, stalks different lengths (5 cm, 10 15 cm) were co-composted with pig manure for 49 days. The results showed that cm treatment (T2) maintained a high-temperature stage 8 days, and total organic carbon decreased by 60.0%. T2 highest cellulose (57.0%) hemicellulose (77.1%) degradation rate, lowest lignin accumulation (69.8%), humus content (34.94 g/kg), which was 88.1% higher than in initial stage. FTIR analysis revealed significant changes functional groups. aromatic C=C stretching vibration (1650 cm−1) group increased 79.8%, showing better aromatization degree other two Two-dimensional spectroscopy phenolic alcohol hydroxyl groups first involved followed polysaccharides, hemicellulose, lignin, structures, enhanced this material transformation pathway. Microbial diversity identified seven main phyla, among Planctomycetota Acidobacteria abundance, closely related cellulose, compounds. Second, abundance characteristic species such as Planifilum fulgidum also certain advantages group. summary, optimized microbial activity matter effectively regulated composting humification process.

This study analyzed the effects of thermohydrolysis on anaerobic conversion efficiency lignocellulosic biomass, comparing conventional and microwave heating methods. The research aimed to identify optimal temperature duration for biomass pre-treatment maximize biogas output. Four temperatures (100 °C, 130 150 180 °C) six durations (10, 15, 20, 25, 30, 40 min) were tested. results showed that increased production compared at same durations. At 20 min produced 1184 ± 18 NmL/gVS biogas, which was 16% more than 1024 25 achieved through heating. Statistically significant differences in output between observed with greatest difference recorded °C °C: 13% 18% Notably, increasing from did not result a statistically rise production. energy balance analysis revealed heating, despite its lower resulted higher net gains. most favorable gain 170.8 Wh/kg, while 126.2 Wh/kg. Microwave became cost-effective starting yielding an surplus 18.2 maximum conditioning 426 Wh/kg 158 These findings suggest thermohydrolysis, particularly min, enhances both highlight potential as effective strategy boost methane fermentation yields, especially above °C.

Sewage sludge was treated with nanoscale zero-valent iron (nZVI) to enhance biogas and methane (CH4) production, the influence of key parameters on material’s anaerobic digestion (AD) efficiency analyzed using sigmoidal mathematical models. In this study, three dosages nZVI (0.5%, 1.5% 3%) were added system accelerate decomposition process. The results showed that cumulative yield after 41 days increased by 23.9% in reactor a dosage 1.5%. Correspondingly, highest CH4 production enhancement 21.5% achieved compared control. indicated optimal for AD system, as it governed yields maximum removal total volatile solids. Additionally, predict evaluate kinetic parameters, eight models applied. According modified Gompertz, Richards logistic models, shortened lag phase from 11 5 Schnute model provided best fit experimental data due coefficients determination (R2: 0.9997–0.9999 at 3% dosages), well lowest Akaike’s Information Criterion values errors. This demonstrated its superior performance other

Biomass is a significant renewable feedstock for the generation of bioenergy and gateway to shift from fossil fuels energy system. Efficient fractionation biomass into main components (cellulose, hemicellulose, lignin) still problem due its complexity. Organosolv recently emerging pretreatment technology that employs organic solvents selectively fractionate with high purity. In present review, organosolv thoroughly discussed in context solvent selection, use catalyst, comparison other processes. Biochemical thermochemical routes fractioned are also provided. Systematic search critical evaluation peer‐reviewed literature 2000 2024 scientific databases such as Web Science, Scopus, Google Scholar were made review. A rigorous screening procedure resulted inclusion 191 relevant articles, concentrating on recent innovations real‐life applications fractionation. The findings show enhances efficiency conversion product diversity adheres principles circular bioeconomy through recovery production valuable bio‐based chemicals. Despite promising characteristics, process faced challenges like operating costs low recovery, and, therefore, more research required implement it large‐scale This review focuses relevance clean potential be included future biorefinery systems allow transition toward low‐carbon era.

Due to the increasing global demand for feed protein, microbial protein has great potential of being able sustainably. However, application in animal cultivation industry is still limited by its high cost and availability on scale. From viewpoint industrial production, it vital specify crucial processes components further technical exploration process optimization. This article presents state-of-the-art technologies non-protein nitrogen (NPN) assimilation production. Nitrogen sources are one main factors media used large-scale fermentation. Therefore, available NPN synthesis, utilization mechanisms, fermentation corresponding strain reviewed this paper. Especially, random mutagenesis adaptive laboratory evolution (ALE) approach combined with (ultra-) throughput screening provided impetus increase yield. Despite underlying technological advances production extensive research development efforts required before commercial feed.
