Alternative methods for the wool wax extraction from wool scouring wastes

Grasas y Aceites, 2007
Wool fibers have to be properly washed out before being processed into fabrics. This scouring process generates high pollutant wastes in two forms, a liquid phase and a solid phase. Both phases contain a large amount of the grease (wool wax) generated by

Lubricating Grease From Waste Cooking Oil And Waste Motor Sludge

, 2016
Increase in population has increased the demand of energy to fulfill all its needs. This will result in burden on fossil fuels especially crude oil. Waste oil due to its disposal problem creates environmental degradation. In this context, this paper studies utilization of waste cooking oil and waste motor sludge for making lubricating grease ...

Exploring The Co-composting Potentials of Raw Grease Trap and Grease Trap-Derived Soaps: Insights into Grease Trap Modification, Calcium Supplementation, and Microbial Community Analysis

Applied Environmental Research
Managing waste with grease traps poses a challenge because of the potential environmental issues associated with its disposal. In this study, two approaches were investigated to increase the biodegradability of grease trap waste: 1) converting raw grease

OPTIMIZATION OF COMPLEX TECHNOLOGY FOR GREASE WASTES UTILIZATION

Environment. Technology. Resources. Proceedings of the International Scientific and Practical Conference, 2015
Lipids constitute one of the major types of organic matter found in municipal wastewater. Many manufacturing, food processing and industrial facilities dispose of liquid waste into sewer lines. Liquid waste often contains fats, oils and grease and other organic contaminants which, over time, lead to clogs in pipes.

Mineral base oil recovery from waste lubricant grease

Rwanda Journal of Engineering, Science, Technology and Environment, 2018
Lubricants play an important role in the running of automotive and related machines. They prevent wear and tear of machines through the provision of a protective film between two moving parts. With time, the performance of grease is reduced creating a problem of waste lubricant grease.

Methane and Hydrogen Sulfide Production from Co-Digestion of Gummy Waste with a Food Waste, Grease Waste, and Dairy Manure Mixture

, 2019
Co-digestion of dairy manure with waste organic substrates has been shown to increase the methane (CH4) yield of farm-scale anaerobic digestion (AD). A gummy vitamin waste (GVW) product was evaluated as an AD co-digestion substrate using batch AD testing.
