There are many benefits of the CSB. Because we pair projects in close proximity, the CSB is the most environmentally protective approach to soil recycling. This is because transport distances are kept to a minimum and trucking fuel consumption is reduced by 80% compared to traditional disposal methods. In the first three years of operation, the CSB has lowered truck transportation by over 1.2 million miles and reduced diesel fuel consumption by 250,000 gallons. By lowering fuel consumption, we have also reduced greenhouse gas emissions by 2,500 tons and lowered many other truck exhaust pollution emissions. Direct exchange between construction projects also eliminates use of soil processing facilities and lowers the burden these facilities pose in environmental justice communities.
