A review of recent advances in the synthesis of environmentally friendly, sustainable, and nontoxic bio-lubricants: Recommendations for the future implementations

Environmental Technology & Innovation, Journal Year: 2023, Volume and Issue: 32, P. 103366 - 103366

Published: Sept. 20, 2023

Conventional petroleum-based lubricant resources are depleting rapidly, and their utilization severely threatens the environment. Environmental sustainability emphasizes need for an alternative to petroleum resources. The lubricants play a significant role in machinery's adequate energy-saving performance. Therefore, tribological aspects of maximum efficiency should be considered. current study reviews part bio-lubricants towards environmental sustainability. This review has been conducted according PRISMA approach, where sources bio-lubricants, performance, additives nanoparticles, benefits disadvantages, production techniques, economic aspects, future scope were explored discussed. Bio-lubricants possess better viscosity index, lubricity, biodegradability, non-toxic renewable nature than lubricants. However, lower thermo-oxidative stability higher pour points due moisture content require further improvements. Food security is another concern bio-lubricants. Consequently, it emphasized importance algae-based bio-lubricant reducing threat food security, water purification, greenhouse gas mitigation. Further improvements optimization methods required increase yield rates promote new (algae-based) bio substitutes with details physicochemical properties sustainable highlighted this research.
