Journal of Material Cycles and Waste Management, 20(4), 2100-2109.1438-49571611-8227https://doi.org/10.1007/s10163-018-0764-zhttps://link.springer.com/article/10.1007/s10163-018-0764-zhttp://hdl.handle.net/11452/34100The compostability of water-based paint sludge originating from the automotive industry was investigated. Six reactors were operated. Wastewater treatment sludge from the same industry was used as additional substrate, and corncob was used as a bulking agent. The level of paint sludge within the compost mixtures varied between 55 and 85%. All reactors yielded a temperature increase up to thermophilic phase levels (>40 degrees C) for a minimum of 5days, and organic matter and C/N losses were observed. BTEX concentrations decreased during composting. Nickel and tin levels in the final product exceeded the legal compost limits. The calorific value of the compost mixtures increased from 9532 to 18774kJ/kg at the end of the composting process. It was seen that the process applied in this study can be utilized as a biodrying step before the usage of paint sludge at cement kilns as additional fuel.eninfo:eu-repo/semantics/closedAccessEnvironmental sciences & ecologyBiodryingCompostingTreatment plant sludgeWaste managementMoisture-contentMelamine resinManureAir pollution controlAutomotive industryBrickmakingCementsIndustrial wastesKilnsMixturesPaintAutomotive manufacturingWastewater treatmentBio-dryingCement kilnTemperature increaseThermophilic phaseWastewater treatment sludgeWater-based paintsIndustrial wastesWaste treatmentArticle0004457598000192-s2.0-8505082961721002109204Environmental sciencesSludge Composting; Compost Quality; Compost
