Concrete Batching - an overview | ScienceDirect Topics
Over a 6-month summer/autumn period, the energy consumption and production levels of six different concrete-batching plants were audited. The average CO 2 emissions due to batching per cubic meter of concrete produced were found to be 0.0033 t CO 2-e/m 3. Fig. 1.4 shows the contributions of each energy source to the total CO 2 emissions.
