Grinding is a versatile and popular finishing operation for achieving high surface quality products within a precise tolerance. It is primarily used in modern industries to grind superalloys, ceramics, composites and many difficult-to-cut materials that cannot easily machined by other traditional machining methods. Despite positive grinding outputs, this process suffers serious drawbacks, including excessive heat generation, which is more than ten times that of other traditional machining operations. To degrade temperature, conventional cutting fluid is applied in the compact grinding zone. Unfortunately, conventional cutting fluids are mostly petroleum-based and mainly extracted from crude oil. Furthermore, conventional fluids react at elevated temperatures, leading to environmental pollution and increases workers health concerns. All these factors are responsible for exploring sustainable alternatives to improve cutting fluid management and detract all issues by maintaining maximum efficiency and quality. The sustainable concept reduces environmental impact, minimizes fluid wastage, uses biodegradable cutting oils and enhances economic and social benefits. This chapter highlights the important sustainable concepts used in modern grinding processes, including vegetable oil lubricants, minimum quantity lubrication (MQL), green nanofluids, cryogenic grinding, ultrasonic-assisted grinding, and hybrid grinding systems. Results show that sustainable processes decrease heat generation, improve surface texture, increase abrasive wheel life and reduce grinding forces. Therefore, it can be an alternative to conventional mineral-based cutting fluid for increasing grindability and minimizing environmental problems.
