What to do with "concrete waste" at any type of concrete plant

What to do with waste concrete? Let's get two things cleared up right away: This information applies to any type of concrete operation, be it ready-mix, precast, block, pipe, etc. As an industry, we need to stop calling it waste. Waste has regulatory meanings, and sounds like garbage. Your excess material is not waste. More on that below.

EWC codes | List Of Waste

When waste is moved or disposed of you must use a waste transfer note/consignment note. This describes the waste, producer of the waste and the disposal point. A standard coding system classifies and describes the type of waste. These are called EWC Codes (European Waste Codes) as specified in the List Of Waste Regulations.
