Circular Economy
main raw material: water.
The following procedures were validated and implemented: quality control of the produced concrete with recycled or combined water; usage of recycled water in the production of concrete, truck washing and maintenance system of recycled water. These procedures adjust to the existing regulations and establish the steps to follow for the recycling of water and allow recording the data and using the information, so the concrete plant can show its operational practices associated to this activity.
In the procedure of concrete quality control, the data obtained by the quality of water and the concrete properties, adjusting to the local and international regulation requirements, the forging time and compression resistance shows on a calculation sheet, along with documentation ready to be revised and audited. Regarding the usage of recycled water in the concrete production, the daily data is transformed, using a calculation sheet, showing the amount of recycled water used, and its proportion according to the potable water, which can help develop strategies to increase recycling and diminishing the usage of potable water as raw material. Additionally, it allows us to estimate the daily concrete production with the storage of recycled water, and even the possibilities of sharing this water with other concrete plants, in cases of low demand of concrete production. The disposal of residual water sedimentation, originated from truck washing are also accounted in these procedures. They are the main reasons to move in the road of sustainability. By turning this dried mud into sub-products inside and outside the premixed concrete plant, there is no doubt that the concrete plant is moving in the road towards circular economy.
