EXTRACTION With the exception of slag and other manufactured aggregates most materials for aggregate production come from bedrock or unconsolidated deposits.

Discrete vs. Process Manufacturing ProcessPro

The raw materials used to create these products are the same from the first job to the next. Process manufacturing becomes more intricate due to its nature in converting/transforming raw materials and ingredients. With process manufacturing, the end product is unable to be unassembled to its original raw materials.
