Environmental Impact of Aggregates - Concrete

In some cases, silt particles can be recovered by flocculation so that they can be used as part of the fine aggregate. To minimise transport costs, aggregates are processed at their source or the landing point of marine materials. The major environmental concerns of aggregate production are outlined in the Table.
