Environmental Impact of Concrete Batch Plants in Texas
Concrete batch plants are environmentally responsible.
A standard concrete plant permit limits particulate matter (such as dust) to less than 5 pounds per day for the entire facility. By comparison, an unpaved road can generate 5.5 pounds of particulate matter in a single day.
As an example, in Hays County, Texas, there are 145 miles of unpaved roads that with a single vehicle per day, could generate 798 pounds of particulate matter per day, which is significantly greater than an average ready-mix concrete plant. In other words, regular traffic on dirt and gravel roads actually produces more particulate matter than any single concrete batch plant.
Most concrete batch plants repurpose rainfall and water that is used on site. Facilities utilize storm water and process water collection systems on-site to collect and repurpose water back into the production process at the facility for aggregate cooling, dust suppression, and wash-down water for trucks. Every gallon that is repurposed in this manner, translates to water supply savings. A concrete batch plant’s municipal water usage can be cut by as much as 50 percent by using this type of water management approach. This means that an average concrete plant may consume the same (or even less) than 10 neighboring households.
