Uçaroğlu S, Gümrah BG. Management of water-based paint sludge originating from the automotive industry via composting. JOURNAL OF THE AIR & WASTE MANAGEMENT ASSOCIATION (1995) 2024; 74:279-289. [PMID: 38330298 DOI: 10.1080/10962247.2024.2316821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Accepted: 02/01/2024] [Indexed: 02/10/2024]
Abstract
Water-based paint sludge generated from the automotive industry is considered a hazardous waste due to its high carbon content and is challenging and costly to manage. This study investigates the management of water-based paint sludge through the composting process, considering its high carbon content. The water-based paint sludge was composted in five separate reactors with the addition of treatment sludge from the same industry as co-substrate and inoculum, as well as sunflower stalks as a bulking agent. The ratio of paint sludge added to the compost mixtures varied between 40% and 80%. The highest temperature was achieved in reactors where industrial sludge was added, and the bulking agent was used at a rate of 20% (R3 and R5). The most efficient composting process was conducted with the addition of 60% water-based paint sludge, 20% treatment sludge, and 20% sunflower stalks (w/w, wet weight basis) (R3). During this process, reductions in organic matter content were observed due to organic matter mineralization, resulting in a decrease in moisture during the maturation phase and consequently reducing waste volumes. The composting process can be a useful tool in addressing the challenges of paint sludge management. Utilizing the composting process not only reduces waste volumes, thereby minimizing environmental impacts, but also offers a sustainable approach to paint sludge management by lowering disposal costs. It is also possible to achieve more effective results by composting paint sludge with different recipes and the use of various bulking agents.Implications: Composting is a method that can be used to achieve stabilization, reduce the quantity, and enable biodrying of water-based paint sludge generated from the automotive industry. In this study, different ratios of paint sludge were mixed with treatment sludge from the same industry as co-substrate and inoculum, while sunflower stalks were added as a bulking agent, and a composting process was conducted. The addition of industrial wastewater treatment sludge and sunflower stalks has increased the efficiency of the paint sludge composting process. In the management of paint sludge, the composting process has emerged as a significant alternative that reduces disposal costs and environmental impacts.

JOURNAL OF ENVIRONMENTAL MANAGEMENT 2023; 328:116962. [PMID: 36470002 DOI: 10.1016/j.jenvman.2022.116962] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Revised: 11/21/2022] [Accepted: 12/01/2022] [Indexed: 06/17/2023]
Abstract
The present study experimentally quantified the pyrolysis behaviors of waste solvent-based automotive paint sludge (OAPS) and water-based automotive paint sludge (WAPS) at four different heating rates using thermogravimetric-Fourier transform infrared (TG-FTIR) spectrometry and pyrolysis-gas chromatography-mass (Py-GC/MS) spectrometry analyses. Flynn-Wall-Ozawa (FWO) and Kissinger-Akahira-Sunose (KAS) methods combined with the master-plots method were employed to investigate the pyrolysis kinetics and reaction mechanisms of waste automotive paint sludge. Three reaction stages and three reaction peaks in stage 2 were distinguished for both OAPS and WAPS degradation. The average activation energy (Ea) estimates for OAPS (FWO: 179.09 kJ/mol; KAS: 168.28 kJ/mol) were slightly higher than WAPS (FWO: 175.90 kJ/mol; KAS: 164.80 kJ/mol) according to FWO and KAS methods. The main pyrolysis reaction mechanisms of both OAPS and WAPS closely matched with the order-based model corresponding to 3rd and 2nd order random nucleation on an individual particle. The evolved gas species of CH4, CO2, phenols, NH3, H2O, and CO from OAPS and WAPS pyrolysis were identified by TG-FTIR. According to Py-GC/MS, hydrocarbons (47.2%) and O-components (42.7%) were relatively large after OAPS and WAPS pyrolysis, respectively. Melamine was the most abundant N-component product after pyrolysis of OAPS (5.8%) and WAPS (4.8%).

Abstract
Paint sludge (PS) is a waste product coming from spray application of paints in automotive industry. For the first time, this work assessed the economic costs and environmental impacts connected to recycling PS in bituminous binders for asphalt pavement applications. Previous works have demonstrated that PS could be used as a replacement of up to 20% (w/w) of neat bitumen in the production of hot mixture asphalts (HMAs), without worsening the technical performances of pavements. The annual production of PS from Italian automotive plants (3000 t/year) could be accommodated in a paved area of 1.64 km2 that, when employed in local roads, with an average width of 5 m, corresponds to approximately 330 km. Costs for treating PS to be prepared for recycling resulted in 144 €/t raw PS. This cost was of the same order, or even less, of that required for PS incineration or disposal in a landfill for hazardous waste (250-300 €). The LCA analysis revealed that the production of HMAs by employing a binder that contains 20% (w/w) of PS, reduced the gross energy requirement (GER) and global warming potential (GWP) indexes by 15% and 39%, respectively, compared to an HMA produced with the traditional process.

Abstract
Vermicomposting is an eco-friendly method for treating organic wastes. This study investigated the effects of the addition of straw (S), biochar (B), nanocarbon (N), S + B and S + N to cow dung (CD) on earthworm (Eisenia fetida) performance, microbial properties and vermicompost quality. In general, the earthworm growth rate and cocoon production were enhanced by straw addition, but were inhibited by biochar or nanocarbon addition. However, biochar and nanocarbon increased microbial communities associated with organic matter decomposition, and improved metabolic functions, enzyme activities and vermicompost properties. Moreover, addition of straw in combination with nanocarbon resulted in the highest vermicompost quality index (VQI), and significantly increased the biomass of three different test crops (radish, lettuce and pakchoi). These results indicated that biochar and nanocarbon mainly improved microbial activities, while straw primarily enhanced earthworm performance during vermicomposting. In addition, straw combined with nanocarbon can be used to enhance the agronomic performance of vermicompost.

Abstract
Nutrient loss is a major problem during agricultural waste composting. This study investigated the impact of gasification filter cake (GFC) addition on gaseous emissions and nutrient loss during composting of chicken manure mixed with Caraganna microphylla straw. The GFC was added to the composting mix at dry weight rates of 0% (GFC0), 6.25% (GFC6.25), 12.5% (GFC12.5), 25% (GFC25) and 50% (GFC50). Overall, GFC12.5 and GFC25 efficiently enhanced organic matter decomposition, reduced N loss and enriched P and K concentrations during composting, as compared to GFC0. However, GFC6.25 did not show a significant effect on organic matter decomposition, while GFC50 had no effect on N loss. As a result, an overall enhancement of nutrient contents was observed in the final composts of GFC12.5 and GFC25. These results suggest that the addition of GFC at moderate-rates (i.e. 12.5% and 25%) can enhance nutrient retention and thereby result in a nutrient-rich compost.

Abstract
As a heterogeneous fraction, dissolved organic matter (DOM) in a compost is the most active because of its direct supply of energy sources for microbes. Also, the transfer and distribution of heavy metals in the DOM fraction attract many attentions of researchers. To this end, the dynamics of humic acids (HA), fulvic acids (FA), hydrophobic neutrals (HoN), and hydrophilic (Hi) fractions derived from DOM was investigated in this study, and the transformation of different DOM subfractions and distribution of heavy metals during food waste and sugarcane leaves co-composting were assessed by excitation-emission matrix fluorescence (EEM-FL) and inductively coupled plasma mass spectrometry (ICP-MS), respectively. The results revealed that HA transformed from polycyclic aromatic humic acid-like to polycarboxylic humic acid-like and FA changed from soluble microbial products (SMP) to humic acid-like; Hi and HoN composed mainly of SMP substances; FA showed more abundant compositions, such as SMP, humic acid-like and tryptophan. Heavy metals (As, Cd, Cr, Cu, Hg, Ni, Pb and Zn) were redistributed among different DOM subfractions in the thermophilic phase of composting. Compost DOM and its subfractions showed obvious effects on germination index (GI), biomass, root length, shoot length and healthy index of Chinese cabbage seedlings. These findings shed some novel lights into the dynamic composition and characteristics of DOM subfractions and their impacts on heavy metals distribution in a composting process.

Abstract
Melamine-based resins are used extensively in laminates, plastics, coatings, glues, and dinnerware. Little is known, however, about the occurrence of melamine and its derivatives in the environment. In this study, a nationwide survey of melamine and its derivatives, namely ammeline, ammelide, and cyanuric acid, was conducted, using archived sewage sludge samples collected from 68 wastewater treatment plants in the United States (U.S.). The sum concentrations of four target compounds in sludge ranged from 34 to 1800 ng/g dry weight (dw), with a mean concentration of 240 ng/g dw; melamine (46%) and cyanuric acid (40%) collectively accounted for 86% of the total mass of analytes. No significant geographical variation in the concentrations of melamine and its derivatives in sewage sludge was found. The estimated emission of melamine and its derivatives via land-application of sludge was approximately 1600 kg/yr in the U.S. The hazard quotient values for melamine in sludge-amended soils ranged from 2.2 × 10-5 to 4.4 × 10-3, indicating that the current levels of melamine in sludge pose a minimal risk to the soil environment.

Abstract
The aim of this study was to investigate the influence of inoculants on compost stability, maturity and enzyme activities during composting of chicken manure and cornstalk. Two microbial inoculants (originated from aerobic municipal sludge and municipal solid waste, respectively) were used in composting at the rate of 0.3% of initial raw materials (wet weight). No microbial inoculums were added to the control. The experiment was conducted under aerobic conditions for 53 days. The results show that enzyme activity is an important index to comprehensively evaluate the composting stability and maturity. Microbes originated from sludge works best in terms of composting stability and maturity (C:N ratio decreased from 15.5 to 10, and germination index increased to 109%). Microbial inoculums originated from sludge and municipal solid waste extended the time of thermophilic phase for 11 and 7 days, respectively. Microbial inoculums originated from sludge and MSW significantly increased the average of catalase activity (by 15.0% and 12.1%, respectively), urease activity (by 21.5% and 12.2%, respectively) and cellulase activity (by 32.1% and 26.1%, respectively) during composting.

Abstract
Green waste was separately inoculated on day 0 and day 14 with either Trametes versicolor or Phanerochaete chrysosporium to determine their effects on composting time and compost quality. Inoculation with T. versicolor and P. chrysosporium caused more rapid and higher increases in compost temperatures, increased the duration of the thermophilic temperature stage, and reduced the maturity time. Inoculation with T. versicolor and P. chrysosporium greatly increased the quality of the final composts in terms of pH, electrical conductivity, organic matter concentration, C/N ratio, germination index, and nutrient content. Inoculation with T. versicolor and P. chrysosporium also significantly increased the degradation of lignin by 7.1% and 8.2%, respectively, and increased the degradation of cellulose by 10.6% and 13.6%, respectively.

Jiang J, Liu X, Huang Y, Huang H. Inoculation with nitrogen turnover bacterial agent appropriately increasing nitrogen and promoting maturity in pig manure composting. WASTE MANAGEMENT (NEW YORK, N.Y.) 2015; 39:78-85. [PMID: 25769536 DOI: 10.1016/j.wasman.2015.02.025] [Citation(s) in RCA: 110] [Impact Index Per Article: 12.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2014] [Revised: 01/05/2015] [Accepted: 02/18/2015] [Indexed: 06/04/2023]
Abstract
The nitrogen turnover bacterial (NTB) agent, which is closely related to nitrogen turnover, was comprised of a bacterial consortium of ammonifiers, nitrobacteria and Azotobacter in this study. The three constituents of the bacterial consortium were added to pig manure and wheat straw mixtures in different doses and at different times, and subsequently composted to investigate their effects on nitrogen transformation and maturity. Throughout the period, the total N loss was 35-56%, 10.7-22.7% of which consisted of NH3, and 18-35% of the initial organic carbon was degraded. Adding the NTB agent prolonged the thermophilic stage by one to six days compared to the control. The lowest N loss (35%), the highest degradation rate of organic carbon (35%) and the greatest increase in total nitrogen content (36.1%) occurred in the inoculation with 1% NTB agent at the beginning of composting. However, adding 1% NTB agent after the thermophilic stage and 3% NTB agent at the beginning of composting had no positive effect with respect to retaining nitrogen or accelerating the maturation process. Therefore, the inoculation with 1% NTB agent at the beginning of composting was effective for reducing N loss and promoting maturity.

JOURNAL OF HAZARDOUS MATERIALS 2012; 243:28-36. [PMID: 23127275 DOI: 10.1016/j.jhazmat.2012.09.013] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/06/2012] [Revised: 09/06/2012] [Accepted: 09/07/2012] [Indexed: 06/01/2023]
Abstract
Melamine resin (MR) is introduced to the environment from many industrial effluents, including waste paint sludge (WPS) from the automobile industry. Melamine resin contains a high nitrogen (N) content and is a potential N source during composting. In this study, two carbon sources, waste paper (WP) and plant residue (PR), were used to study their effects on composting of WPS. Additional work tested the WPS-composts effects on plant growth and soil water quality. After 84 days of composting, 85% and 54% of the initial MR was degraded in WP- and PR-composts, respectively. The limiting factor was that the MR created clumps during composting so that decomposition was slowed. Compared to the untreated control, both WP- and PR-composts increased growth of cucumber (Cucumis sativus), radish (Raphanus sativus) and lettuce (Lactuca sativa). Concentrations of trace elements in plants and soil water did not rise to a level that would preclude WPS-composts from being used as a soil amendment.
