DETERMINING THE RECYCLED CONTENT OF CONCRETE

For each product, the recycled content value is determined as the percent recycled content multiplied by the total product cost for the project. For the hypothetical project referenced in Figure 1, if the total cost of the concrete masonry units is $90,000, the recycled content value of the concrete masonry units is 0.365 ($90,000) = $32,805.
