Lard
Other uses

Rendered lard can be used to produce biofuel and soap. Lard is also useful as a cutting fluid in machining. Its use in machining has declined since the mid-20th century as other specially engineered cutting fluids became prominent. However, it is still a viable option. Lard and other animal fats were formerly used as an anti-foaming agent in industrial fermentation processes such as brewing; there, animal fats have been superseded by polyethers.
