“…The removal of RBB dyes increases from 5 to 60 minutes then relatively constant. It is in accordance with a research conducted by Torgut et al [33] in which RBB removal by activated carbon polymer reached equilibrium after 60 minutes. In order to evaluate the kinetics of the dye removal, pseudo-first order and pseudo-second order kinetic models are proposed.…”

This work implicates the synthesis of biochar-hematite nanocomposite from bamboo sawdust and its photodegradation characteristic for remazol brilliant blue. The nanocomposite was prepared through a one-step pyrolysis process in a tubular furnace under a flow of nitrogen and impregnation using FeSO4.7H2O and FeCl3.6H2O. The physicochemical properties were characterized by x-ray diffraction and Fourier transform infrared spectroscopy, which confirmed that hematite was successfully identified on the surface of the nanocomposite. The results also show that the nanocomposite is suitable for photodegradation application. The decolorization of remazol brilliant blue is suitable with the Langmuir isotherm model and pseudo-second-order kinetic model. At pH = 1, initial concentration = 200 mg/L, contact time = 60 minute and nanocomposite dosage 0.4 g/L, the decolorization efficiency reached 96.9%.

“…It may be due to the higher initial concentration of the solution increases the driving force to overcome all mass transfer resistance in the adsorption process [21]. time greatly affects to the amount of RBB uptake [33]. Contact time is very important to determine the equilibrium time of RBB uptake [30].…”

“…Pyrolysis can be carried out using catalyst (Alfernando et al, 2019;Prabasari et al, 2019;Fitriyanti, 2020) or without catalyst (Ayodeji and Oni, 2018;Alfernando, Nugraha, Prabasari, Haviz, Nazarudin, 2020). Due to a quite expensive catalyst, thermal cracking is more preferred despites its limitation in selectivity (Gaur, Mishra, Chowdhury, Baredar, Verma, 2020).…”

Pyrolysis is the one solution to recycle hydrocarbon-based waste material such as used lubricant and cooking oil. The aim of this research was to determine the effect of temperature and sample ratio on the liquid yields of a mixture of used lubricant and cooking oil. The semibatch reactor was used with a constant nitrogen flow rate of 5 mL/min. Three different ratios of sample mixture were applied in this experiment: 0.5:1, 1:1, and 1.5:1, and three different temperatures: 4000C, 4500C, and 5000C. The thermal pyrolysis of a mixture of used lubricant and cooking oil was deemed as the most effective pyrolysis to produce liquid fraction was obtained from reaction condition with the sample mixture ratio of 0.5:1 at 5000C. At this reaction condition, the liquid yields was 58.90% which consist of 64.12% were C1-C3 and 29.54% were C5-C15. Liquid fraction is predicted to increase as the temperature increase and the ratio of used lubricant to cooking oil decrease. When the ratio is increased , more gas fraction is produced.

“…In the context of biodiesel production from WCO, it has been reported that the heterogeneous over homogeneous catalysis has great advantages due to its lower cost, lower corrosion, reuse, and easy separation (Gaur et al, 2020). The generation of residues in the reaction is a variable to consider for the determination of the environmental impacts in a LCA.…”

The objective of this work was to assess the environmental impacts of producing biodiesel by heterogeneous and homogeneous catalysis. The raw material for the process was the waste cooking oil (WCO) generated at 27 food courts of Autonomous University of the State of Mexico. The study was conducted by applying Life Cycle Assessment methodology and the environmental impacts were calculated with the SimaPro 9.1.0.11 PhD software with the Ecoinvent database. The method was CML-IA base line C3.06/EU25. The assessed impact categories were: Abiotic Depletion Potential (ADP, elements), Abiotic Depletion Potential (ADP, fossil fuels), Global Warming Potential (100 years) (GWP), Ozone Layer Depletion (ODP), Human Toxicity (HT), Freshwater Aquatic Ecotoxicity (FWAE), Marine Aquatic Ecotoxicity (MAE), Terrestrial Ecotoxicity (TE), Photochemical Oxidation (PO), Acidification (A) and Eutrophication (E). In addition, end point environmental indicators were also calculated (Ecosystems Quality, Human Health Damage and Resources Availability) by the method ReCiPe 2016 Endpoint (H) V1.04 / World (2010) H/A. The system boundary enclosed three main stages, WCO collection, pre-treatment and reaction (to produce biodiesel). It was concluded that the reaction stage is the one with the highest environmental impact. In this sense, the highest impact categories were ADP (fossil fuels) (105.56 MJ), GWP (8.91 kg CO2 eq) and MAE (2387.89 kg 1, 4-DB eq). Nevertheless, it was also found that the GWP for the heterogeneous process is 82.52 % lower than that calculated for the homogeneous process. In addition, the human health damage of the homogeneous process is 1.77 points and is higher than the observed with the heterogeneous process.
