    Concrete batching is generally conducted at plants located at various strategic positions around a city or town to minimize transport time. Raw materials are mixed in elevated bins and placed directly into concrete trucks for final transport. This process is primarily powered by electricity, with small amounts of other fuels used on each site by small excavators used to move raw materials, etc.
