[PMID: 38408502 DOI: 10.1016/j.biortech.2024.130491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/20/2023] [Revised: 02/21/2024] [Accepted: 02/22/2024] [Indexed: 02/28/2024]
Abstract
This study introduced two deep eutectic solvents, ChCl/oxalic acid (CO) and ChCl/ethylene glycol (CE), into a 34-day co-composting process of distillery sludge and distiller's grains waste to address challenges related to NH3 emissions. The addition of DES increased dissolved organic carbon by 68% to 92%, offering more utilizable carbon for microorganisms. SYTO9/PI staining and enzyme activity tests showed the CE group had higher bacterial activity and metabolic levels during the thermophilic phase than the control. Bacterial community analysis revealed that early dominance of Lactobacillus and Lysinibacillus in CE accelerated the onset of the thermophilic phase, reduced pile pH, and significantly decreased urease production by reducing Ureibacillus. Consequently, CE treatment substantially dropped NH3 emissions by 73% and nitrogen loss by 54%. Besides, CE fostered a more abundant functional microbial community during the cooling and maturation phases, enhancing deep degradation and humification of organic matter.

Acceleration of the biodegradation of cationic polyacrylamide by the coupling effect of thermophilic microorganisms and high temperature in hyperthermophilic composting. Bioprocess Biosyst Eng 2024; 47:403-415.

Abstract
As a flocculant of sewage sludge, cationic polyacrylamide (CPAM) enters the environment with sludge and exists for a long time, posing serious threats to the environment. Due to the environmental friendliness and high efficiency in the process of organic solid waste treatment, hyperthermophilic composting (HTC) has received increasing attention. However, it is still unclear whether the HTC process can effectively remove CPAM from sludge. In this study, the effects of HTC and conventional thermophilic composting (CTC) on CPAM in sludge were compared and analyzed. At the end of HTC and CTC, the concentrations of CPAM were 278.96 mg kg-1 and 533.89 mg kg-1, respectively, and the removal rates were 72.17% and 46.61%, respectively. The coupling effect of thermophilic microorganisms and high temperature improved the efficiency of HTC and accelerated the biodegradation of CPAM. The diversity and composition of microbial community changed dramatically during HTC. Geobacillus, Thermobispora, Pseudomonas, Brevundimonas, and Bacillus were the dominant bacteria responsible for the high HTC efficiency. To our knowledge, this is the first study in which CPAM-containing sludge is treated using HTC. The ideal performance and the presence of key microorganisms revealed that HTC is feasible for the treatment of CPAM-containing sludge.

Abstract
As a dewatering method of high moisture solid waste sludge, biodrying still faces environmental problems such as material loss and greenhouse gas emission in the process of treatment. In this study, biochar and magnesium chloride were used to explore the synergistic effect of enhancing sludge biodrying and reducing greenhouse gas emissions. The highest temperature of biodrying was raised to 68.2 °C within 3 days, extending the longest high-temperature period to 5 days, which reduced the water content to 28.8 % in the single addition of biochar treatment. The complex addition increased the NH4+-N content of materials by 57.49 % and decreased the NO3--N content of materials by 40.62 %. The use of additives significantly reduced the emissions of CO2, CH4, and N2O compared to the no-addition treatment. The increase in dominant Actinomycetes and Chloroflexibacter was the main reason for the reduction in gas emissions.

WASTE MANAGEMENT (NEW YORK, N.Y.) 2023; 170:341-353. [PMID: 37748282 DOI: 10.1016/j.wasman.2023.09.023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 09/15/2023] [Accepted: 09/18/2023] [Indexed: 09/27/2023]
Abstract
The objective of this study was to investigate the potential effects of thermophilic bacterial consortia on compost efficiency and quality. The application of bacterial consortia resulted in an earlier onset of the thermophilic period (THP), an increased upper temperature limit, and an extended duration of the THP by 3-5 days compared to the control group (CK). Microbial inoculation significantly improved the efficiency of organic matter degradation, as well as the content of water-soluble nitrogen (WSN) and humic acid-carbon (HAC). In the case of consortium Ⅱ inoculation (T2), the activities of cellobiohydrolase, β-glucosidase, and protease were increased by 81.81 %, 70.13 %, and 74.09 % at the THP respectively compared to CK. During the maturation stage, T2 also exhibited the highest PV, n/PIII, n value (1.33) and HAC content (39.53 mg·g-1), indicating that inoculation of consortium Ⅱ effectively promoted substrate maturity and product quality. Moreover, this inoculation effectively optimized the bacterial communities, particularly the growth of Planococcus, Chelatococcus, and Chelativorans during the composting, which were involved in carbon and nitrogen conversion or HAC synthesis. Carbohydrate and amino acid metabolism, and membrane transport were predominant in the consortia-inoculated samples, with an increased gene abundance, suggesting that inoculation contributed to promoting the biodegradation of lignocellulose and the exchange of favorable factors. In conclusion, this study demonstrates that inoculating thermophilic bacterial consortia has a positive impact on enhancing the resource utilization efficiency of agricultural waste and improving the quality of compost products.

Abstract
Landfilling is the most widely used disposal method for municipal solid waste around the world. The main disadvantage of this strategy is formation of leachate, among other aspects. Landfill leachate contains highly toxic and bio-refractory substances that are detrimental to the environment and human health. Hence, the risk(s) of discharging potentially harmful landfill leachate into the environment need to be assessed and measured in order to make effective choices about landfill leachate management and treatment. In view of this, the present review aims to investigate (a) how landfill leachate is perceived as an emerging concern, and (b) the stakeholders' mid- to long-term policy priorities for implementing technological and integrative solutions to reduce the harmful effects of landfill leachate. Because traditional methods alone have been reported ineffective, and in response to emerging contaminants and stringent regulations, new effective and integrated leachate treatments have been developed. This study gives a forward-thinking of the accomplishments and challenges in landfill leachate treatment during the last decade. It also provides a comprehensive compilation of the formation and characterization of landfill leachate, the geo-environmental challenges that it raises, as well as the resource recovery and industrial linkage associated with it in order to provide an insight into its sustainable management.

Abstract
The purpose of this study was to investigate the effect of initial particle size (IPS) on the environmental parameters and heavy metal speciation during sludge composting. Three piles were conducted: fine material (FM, screen underflow), coarse material (CM, oversize product), and mixed material (MM, mix FM and CM in 1:1). Results showed that the temperature trends of the three piles in different layers were highly repeatable during the thermophilic period. With the decrease of IPS, the heating rate and the highest temperature of the pile increased, the thermophilic period was prolonged, and the highest temperature area in the pile shifted to a lower layer. It also promoted the organic matter degradation, compost maturation, and nitrogen fixation effect. Composting had a good effect on the passivation of heavy metals, especially Cd, Cu, and Pb. The passivation effect on Cd and Cu was FM > CM > MM, and on Pb was CM > FM > MM. Fourier transform infrared spectroscopy, excitation-emission matrix, and thermogravimetric thermal analysis indicated that FM had the highest content of aromatic structure and humic-like substance on D40. The redundancy analysis revealed that MM was beneficial to improve the internal uniformity during composting.

Abstract
The 34-day anoxic storage of Pinus massoniana sawdust (PS) in a sealed constant temperature and humidity chambers was carried out to simulate the limited-oxygen storage process inside piles at industrial scale. The effects of anoxic storage on feedstock's properties and pelletization process were investigated with respect to elemental composition, dry matter loss, thermogravimetric characteristics, energy consumption, pellets' density, and microbial communities, etc. After anoxic storage, the microbial community of PS samples was altered, such as the fungi content (Clonostachys, Strelitziana, and Orbilia, etc.), resulting the elemental composition of PS was altered. Thus, the cellulose and ash content of the stored PS were increased, while the hemicellulose, volatile, and fixed carbon were decreased. The energy consumption was increased 7.85-21.98% with the increase in anoxic storage temperature and with the additive of fresh soil collected from PS field in storage process. The single pellet density was altered slightly. Meanwhile, the moisture uptake of PS pellets was decreased. After anoxic storage, the combustion behavior of the stored PS became more stable. The results can be applied directly to guide the development of commercial PS storage and pelletization process currently under development in Asia, Europe and North America.

Abstract
This study aimed to reveal the potential effects of exogenous lignocellulases addition on the composting efficiency and microbial communities. The lignocellulases addition at the mesophilic phase (MEP) greatly expedited the substrate conversion and the rise of temperature at the initial stage, driving the early arrival of thermophilic phase (THP), caused by the positive effects of Sphingobacterium and Brevundimonas. When being added at the THP, the potential functions and interactions of microbial communities were stimulated, especially for Thermobispora and Mycothermus, which prolonged the duration of the THP and expedited the humic acid formation. Simultaneous addition (MEP and THP) significantly altered the microbial community succession and activated the microbes that contributed to the lignocellulases secretion, exhibiting the highest cellobiohydrolase (36.19 ± 3.25 U· g-1 dw) and xylanase (47.51 ± 3.32 U·g-1 dw) activity at the THP. These findings provide new strategies that can be effectively utilized to improve the efficiency and quality of composting.

Abstract
Climbing Hempweed (CH) is one of the top ten most obnoxious weeds on the planet, as well as one of the most destructive weeds. Its disastrous spread on the agricultural field has hampered the production of a wide range of crops. Various management techniques have been used to eradicate the weed, but none have been completely successful. As a result, management through the use of weed biomass will aid in the eradication of the weed as well as the production of a value-added product. To utilize invasive weed CH for the production of rotary drum compost (R1) and rotary drum followed by vermicompost (V1), two composting technologies were used. These technologies are being compared on several physicochemical parameters to determine their efficacy. V1 compost had the highest total Kjeldahl Nitrogen (TKN) (3.01%), potassium (3.45%), and total phosphorus (16.42 g/kg) levels, while R1 compost had 2.58% TKN, 2.8% potassium, and 14.25 g/kg total phosphorus. Subsequently, the increasing trends in mitotic index (%) of R1 and V1 samples imply that the cytotoxic effects of CH were decreased due to composting and vermicomposting processes. Genotoxicity assessment revealed that an aberration percentage of 1.64 was observed in 100% concentration of V1 (after 30 days) and 4.34% in R1(after 20 days). R1 and V1 were used to evaluate the performance of Abelmoschus esculentus where the highest fruit harvest was seen at 25% amended R1 compost and 35% amended V1 compost. The application of 25-35% R1 compost and 35-40% V1 compost was found to be the most beneficial for the development of Abelmoschus esculentus. There was no significant difference in heavy metal (Mn, Fe, Cu, Co, and Zn) content in the fruit of Abelmoschus esculentus post-application of R1 and V1 compost.

Abstract
Biodrying in conjunction with compound stone amendment was used to treat kitchen waste, which improved biodrying. After 16 days, the pile moisture content decreased from 68.8% to 23.0%. Lignin, cellulose and hemicellulose concentrations decreased from 104.6 mg g-1 d.b., 322.9 mg g-1 d.b. and 155.9 mg g-1 d.b., respectively, to 74.0 mg g-1 d.b., 224.8 mg g-1 d.b. and 134.5 mg g-1 d.b., respectively. The Shannon index for bacteria increased from 2.5 to 3.1, while for fungi, it decreased from 4.6 to 0.6. The relative abundances of Amino Acid Metabolism and Carbohydrate Metabolism exceeded 7%. The thermophilic phase during the process inactivated the pathogenic microorganisms, increased the bacterial diversity, decreased the fungal diversity, and potentially improved the metabolism of nutrients, including amino acids, carbohydrates, lipids and vitamins. The biomarker analysis and predicated protein sequences provide genetic evidence to elucidate why the thermophilic phase is the peak time for nutrient metabolism.

Abstract
Multiple types of biochemical parameters were determined in the course of the composting process with rice straw and Chinese traditional medicine residues as substrates. The water-soluble fractions (WSFs) were analyzed by excitation-emission-matrix fluorescence (EEM-FL), and the maximum PV/III value (1.2) was observed in thermophilic phase (THP). Bacterial community analysis results indicated that the genera with the capacity of degrading lignocellulose dominated in mesophilic phase (MEP) and THP. The metabolic pathways based on KEGG analysis revealed that the amino acid, carbohydrate and energy metabolism pathways in THP were higher than the other two phases. The correlation analysis between EEM-FL and the bacterial community revealed that the genera with high abundances in the THP were significantly positively correlated with fulvic acid-like materials and humic acid-like organics. The quantification results of the lignocellulose-degrading genes in different phases further verified the key functional bacteria obtained by correlation analysis during the composting process.

Role of lignin and thermophilic lignocellulolytic bacteria in the evolution of humification indices and enzymatic activities during compost production. WASTE MANAGEMENT (NEW YORK, N.Y.) 2021; 119:122-134. [PMID: 33059162 DOI: 10.1016/j.wasman.2020.09.042] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 09/06/2020] [Accepted: 09/07/2020] [Indexed: 06/11/2023]
Abstract
This study aimed to evaluate the effect of lignin content and thermophilic lignocellulolytic bacteria bioaugmentation on composting process. Treatments including bioaugmentation with thermophilic lignocellulolytic bacteria isolates such as Paenibacillus validus, Paenibacillus koreensis, Bacillus nealsonii, a mixture of the three mentioned bacterial isolates and control were compared at two level of organic media (high lignin content and low lignin content) in the form of nested factorial design. Several indices such as humification and enzymatic activities were monitored to evaluate the composting rate. The results revealed that high lignin treatments displayed higher ligninase, xylanase, protease and urease enzymatic activities compared to low lignin treatments. On the other hand, low lignin treatments showed higher level of humification indices, cellulase, beta-glucosidase and alkaline phosphomonoesterase enzymatic activities in comparison with high lignin treatments. Also, all measured enzymatic activities are at their highest between the second and the tenth weeks; however, this trend decreased to reach a steady point from the 18th weeks to the 24th weeks, but for urease enzymatic activity, a totally different trend in high and low lignin treatments was observed. Moreover, the highest humification indices as well as the cellulase and β-glucosidase enzymatic activities were associated to the Bacillus nealsonii isolate and the full consortium. They also displayed the highest ligninase, xylanase, protease, and urease and phosphatase activities. The efficient isolates shortened the time required for completing the composting process for about 2 to 4 weeks compared to the control treatments. For all measured indices, the control treatment had the lowest values.

BIORESOURCE TECHNOLOGY 2021; 320:124357. [PMID: 33166884 DOI: 10.1016/j.biortech.2020.124357] [Citation(s) in RCA: 37] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2020] [Revised: 10/26/2020] [Accepted: 10/28/2020] [Indexed: 06/11/2023]
Abstract
Industrial-scale composting of food waste (FW) was performed at different aeration frequencies (C_5_25: 5 min aeration + 25 min interval, C_10_20: 10 min aeration + 20 min interval, C_15_15: 15 min aeration + 15 min interval and CK: stuffiness) to ascertain the optimal aeration frequency to accomplish polymerization and humification of compost. The tested aeration frequencies affected the oxygen uptake rate, oxygen spatial distribution, and ultimately influenced the humification of compost. Extensive aeration was not beneficial to accumulate nitrogen and phosphorus during composting. Aeration frequency influenced the succession of bacterial community primarily through affecting O2 concentration and the release of various enzymes by these bacteria. Regulating O2 concentration by adjusting aeration strategies may provide guidance for accelerating maturity of composting. Considering various factors, this paper recommends the scheme of heating period (C_5_25), thermophilic period (C_15_15) and psychrophilic period (no aeration).
