Preparation of Industrial Greases from Aircraft Waste Oils

Eco-Friendly Multipurpose Lubricating Greases from Vegetable Residual Oils

Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...

Maltodextrine nanoparticles loaded with polyphenolic extract from apple industrial waste: preparation, optimization and characterization

The main aim of this study was to prepare apple pomace polyphenolic extract (APPE- referred to as a core) loaded into biodegradable and commercially available natural polymer such as maltodextrin (MD-referred to as a shell). The polymer coating potentially improves its low stability and bioavailability and also directs the control release of the encapsulated material. The MD-nanoparticles (NPs)...

Waste oil management: Analyses of waste oils from vehicle crankcases and gearboxes

In accordance with waste strategy for Turkey, the study was carried out to analyses waste engine crankcase oils and waste gearbox oils generated from vehicle maintenance services in order to determine their suitability for recycling, recovery or final disposal based on regulation published by Turkish Ministry of Environment and Forestry on 21 January 2004. The regulation requires all waste oil ...
