Bio-lubricants are environmentally friendly alternatives to traditional lubricants, made from renewable resources like vegetable oils and animal fats. They are designed to reduce friction and wear in machinery while minimizing harmful effects on the environment when spilled or disposed of. These lubricants offer similar performance to conventional options but are biodegradable and non-toxic. Bio-lubricants are increasingly used in various applications, including automotive engines, industrial machinery, and marine equipment, helping to promote sustainability in industries that rely on lubrication for efficient operation.
