Effects of Heating Method and Activating Agent on the Porous Structure of Activated Carbons from Coconut Shells
Waste and Biomass Valorization - Tập 3 - Trang 131-139 - 2011
Xin-hui Duan, C. Srinivasakannan, Kun-bin Yang, Jin-hui Peng, Li-bo Zhang
An extensive experimental study has been attempted to assess the effect of heating method and the activation agent on the pore characteristics of activated carbon from coconut shell. The results show that the textural characteristics of activated carbon improve with increase in holding time until an optimum, while the yield decrease with an increase in the holding time, using conventional activati... hiện toàn bộ
Valorization of the Coagulant Bioactive Compound of the Moringa seed Residue: Treatability of Fish Processing Residuary Waters
Waste and Biomass Valorization - Tập 14 - Trang 4113-4126 - 2023
Marcia Regina Fagundes-Klen, Cristiane Thais Bourscheidt Gullich, Carina Contini Triques, Dalila Maria Formentini-Schmitt, Marcia Teresinha Veit, Rosangela Bergamasco
Moringa oleifera seeds have been studied as a natural coagulant to treat different kinds of wastewater. However, from this seed, ben oil can be extracted, which has other commercial applications, generating a residue. In this study, the purpose is to use Moringa oleifera seeds and the residue from the ben oil extraction to treat a fish processing plant wastewater. Therefore, the research aims at b... hiện toàn bộ
Wet and Coarse: The Robustness of Two-Stage Crude Glycerol Mediated Solvothermal Liquefaction of Residual Biomass
Waste and Biomass Valorization - Tập 11 - Trang 2171-2181 - 2018
Lukas Jasiūnas, Raminta Skvorčinskienė, Linas Miknius
Biomass residues were liquefied via two stage crude glycerol (CG) mediated solvothermal liquefaction (STL) at moderate temperatures with intention for industry-friendly production and direct biopolyol utilisation. Digested sewage sludge, hemp stalk hurd and sugar beet pulp were chosen as the local case feedstocks. The study goal was to investigate how robust CG-mediated STL is in terms of differen... hiện toàn bộ

Current Treatment Technologies of Cheese Whey and Wastewater by Greek Cheese Manufacturing Units and Potential Valorisation Opportunities
Waste and Biomass Valorization - Tập 8 - Trang 1649-1663 - 2017
K. Valta, P. Damala, E. Angeli, G. Antonopoulou, D. Malamis, K. J. Haralambous
In the present study, recording and evaluation of the current practices applied for the treatment of wastewater and cheese whey, derived from ten cheese manufacturing units in Greece, was performed. Wastewater from cheese manufacturing includes milk losses, wastewater generated by the staff and by the washing of equipment, floors and milk transferring vehicles. Based on the study, cheese whey is s... hiện toàn bộ
Energy and Economic Evaluation of the Production of Biogas from Anaerobic and Aerobic Sludge in Brazil
Waste and Biomass Valorization - - 2020
Susan J. B. Cañote, Regina Mambeli Barros, Electo Eduardo Silva Lora, Oscar Almazan del Olmo, Ivan Felipe Silva dos Santos, Jean Agustin Velásquez Piñas, Eruin Marturcelli Ribeiro, João Victor Rocha de Freitas, Hellen Luisa de Castro e Silva
This study conducted energy and economic analysis for biogas production from an Upflow Anaerobic Sludge Blanket (UASB) and activated sludge from the Copasa and Fânia® Wastewater Treatment Plants (WWTP), both of which are located in the city of Itajubá, Minas Gerais, Brazil. The methodology adopted for the research study included Physicochemical laboratory analyses of sludge samples. Furthermore, a... hiện toàn bộ
Improving Polyphenol Extraction from Lemon Residues by Pulsed Electric Fields
Waste and Biomass Valorization - Tập 10 - Trang 889-897 - 2017
Sara Peiró, Elisa Luengo, Francisco Segovia, Javier Raso, María Pilar Almajano
In this contribution, the influence of Pulsed Electric Fields (PEF) of different intensities (3–9 kV/cm and 0–300 μs) on the extraction of Total Phenols from lemon peel residues by pressing was investigated. According to the cellular disintegration index, the optimum treatment time for the increase in permeability was determined as 30 pulses of 30 μs. It was determined that the effect of PEF was i... hiện toàn bộ
Optimized Production of Fatty Acid Ethyl Esters (FAEE) from Waste Frying Oil by Response Surface Methodology
Waste and Biomass Valorization - Tập 12 - Trang 2303-2310 - 2020
Marcelo F. Ortega, David Donoso, Hamza Bousbaa, David Bolonio, Rosario Ballesteros, María-Jesús García-Martínez, Magín Lapuerta, Laureano Canoira
In Europe, recent regulations on advanced biofuels have prompted a search for new fuel sources and the development of synthesis methods meeting the demanding specifications of the sector. However, in developing countries such as Algeria, where a significant stock of frying oil is unused, the use of diesel engines powered with waste-oil-derived biofuels must be explored. In this work, the variables... hiện toàn bộ
