Grease Formulation from Palm Oil Industry Wastes
Waste and Biomass Valorization, 2018The treatment and disposal of petroleum-based lubricant waste presents serious challenges to the grease production industry due to its environmental impact. The use of vegetable-oil-based lubricant can solve such issues. In this study, an experimental grease formulation composed of spent bleaching earth (SBE) as the thickener, waste cooking oil (WCO ...

Conversion of Waste Transformer Oil into Grease
2020This work is aimed to study the viability of waste transformer oil (WTO) as grease’s base oil. The shift of lubricant formulation towards high-performance materials and green formulation has led to the development of various lubricant formulations, including grease. Waste reduction is one of the formulation research trends where waste-based material, i.

Lubricating Grease Handling and Waste Management
2016Lubricating grease just like any other lubricants, its waste require careful disposal as it contain pollutants. In response to economic considerations and environmental protection, there is a growing trend of regeneration and reuse of waste lubricants. Accordingly, this work provides an overview on various ways of handling, disposal, treatment of waste

Thermo-chemical extraction of fuel oil from waste lubricating grease
Waste Management, 2013This study investigated the recovery of oil from waste grease through the process of thermal degradation in an aqueous solution of potassium hydroxide (KOH) followed by solvent extraction. Waste high temperature metal bearing grease was dissolved in a 15 w/w% KOH solution at 80°C while being agitated at 2000 rpm using a shear action agitator for a ...

Life-Cycle Assessment of Biodiesel Produced from Grease Trap Waste
Environmental Science & Technology, 2016Grease trap waste (GTW) is a low-quality waste material with variable lipid content that is an untapped resource for producing biodiesel. Compared to conventional biodiesel feedstocks, GTW requires different and additional processing steps for biodiesel production due to its heterogeneous composition, high acidity, and high sulfur content.

Dynamical modeling for biodiesel production from grease trap wastes
Chemical Engineering Science, 2014Abstract Grease trap wastes have been recently considered as an alternative feedstock for biodiesel production due to its relatively low cost and availability. These wastes are characterized by a high content of free fatty acids (FFA) and then, its processing towards biodiesel requires an esterification.

Enhancing biomethanation of municipal waste sludge with grease trap waste as a co-substrate
Renewable Energy, 2011Abstract Grease trap waste (GTW) presents a challenge to wastewater treatment processes due to its slow biodegradation kinetics, high oxygen demand, and risks of pipeline blockage. The objective of this work was to evaluate the feasibility of GTW as an organic-rich co-substrate to improve biomethane production in the anaerobic digestion of municipal ...

Pyrolysis of Waste Fryer Grease in a Fixed-Bed Reactor
Energy & Fuels, 2007Waste fryer grease (WFG) is an environmentally preferable option for hydrogen production. In the present work, the pyrolysis of waste fryer grease in the absence of catalyst was studied in a fixed-bed reactor. The effects of various operating parameters such as reaction temperature (650−850 °C), carrier gas (N2) flow rate (30−70 mL/min), and reactor ...
