Plants that burn waste fuels enjoy a negative fuel cost (they are paid by industries needing to dispose of materials that have energy content and can be safely disposed of in the cement kiln thanks to its high temperatures and longer retention times). As a result, the inefficiency of the wet process is an advantage—to the manufacturer.

Air emissions in cement and lime manufacturing are generated by the handling and storage of intermediate and final materials, and by the operation of kiln systems, clinker coolers, and mills. Several types of kilns are currently used in cement manufacturing (preheater– precalciner (PHP), preheater (PH),
Cement is seldom used on its own, but rather to bind sand and gravel together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Cement is the most widely used material in existence and is only behind water as the planet's most-consumed resource.
