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 ...

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.

Production and characterization of wax and grease from waste plastic

IOP Conference Series: Materials Science and Engineering, 2021
Abstract World has opened up to start a plastic-free zone. Plastic reusing is the greatest test for us all. During reusing it is important to avoid the potential risk of environmental degradation and hazard. Consuming plastics makes it perilous to the general public. The major focus is to utilize waste grade 4 plastic and generate grease

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.
