If approved,\u00a0the material would be used alongside other aggregates like crushed stone, gravel, and sand.<\/p>\n<p>Florida is a major producer of fertilizer, and that leaves a lot of phosphogypsum as waste. Phosphorous is an important component of fertilizer, helping plants to grow strong roots and increasing crop productivity, according to NPR. To get it, phosphate rock is dissolved in sulfuric acid to make phosphoric acid.<\/p>\n<div class=\"image_wrapper first_wrapper\" readability=\"7\"><img fetchpriority=\"high\" decoding=\"async\" name=\"tccimg_100651094_m\" title=\"Miami skyline - Image via City of Miami Government\" src=\"data:image\/png;base64,R0lGODlhAQABAAD\/ACwAAAAAAQABAAACADs=\" alt=\"Miami skyline - Image via City of Miami Government\" width=\"640\" height=\"320\" class=\"first_image lazy\" data-width=\"1024\" data-height=\"512\" data-url=\"https:\/\/images.hgmsites.net\/lrg\/miami-skyline--image-via-city-of-miami-government_100651094_l.jpg\" data-src-h=\"https:\/\/images.hgmsites.net\/lrg\/miami-skyline--image-via-city-of-miami-government_100651094_l.jpg\" data-src=\"https:\/\/images.hgmsites.net\/lrg\/miami-skyline--image-via-city-of-miami-government_100651094_l.jpg\" data-src-l=\"https:\/\/images.hgmsites.net\/lrg\/miami-skyline--image-via-city-of-miami-government_100651094_l.jpg\" data-src-m=\"https:\/\/images.hgmsites.net\/med\/miami-skyline--image-via-city-of-miami-government_100651094_m.jpg\" data-src-s=\"https:\/\/images.hgmsites.net\/sml\/miami-skyline--image-via-city-of-miami-government_100651094_s.jpg\"\/><\/p>\n<p>Miami skyline &#8211; Image via City of Miami Government<\/p>\n<\/div>\n<p>This commonly used production process, which dates back to the 1840s, isn&#8217;t very efficient, the report explains. For every ton of phosphoric acid produced, more than five tons of\u00a0phosphogypsum waste is produced. The\u00a0phosphogypsum is usually left in massive heaps\u2014called &#8220;gypstacks&#8221;\u2014that can be up to 200 feet high and span 800 acres. They&#8217;ve also been linked to problems like sinkholes. Which explains why lawmakers are so eager to make use of the stuff.<\/p>\n<p>However,\u00a0phosphogypsum also contains &#8220;appreciable quantities&#8221; of the radioactive element uranium and other radioactive elements produced through the natural decay of uranium, according to the EPA. Uranium decay forms radium-226, which in turn decays to form radon, a cancer-causing radioactive gas. These elements are present in the original phosphate rock, but the fertilizer production process concentrates them, making\u00a0phosphogypsum more radioactive than the original rock, according to the EPA.<\/p>\n<div class=\"image_wrapper\"><img decoding=\"async\" name=\"tccimg_100749686_m\" title=\"Big rigs in traffic\" src=\"data:image\/png;base64,R0lGODlhAQABAAD\/ACwAAAAAAQABAAACADs=\" alt=\"Big rigs in traffic\" width=\"640\" height=\"398\" data-width=\"1024\" data-height=\"636\" data-url=\"https:\/\/images.hgmsites.net\/lrg\/big-rigs-in-traffic_100749686_l.jpg\" data-src-h=\"https:\/\/images.hgmsites.net\/hug\/big-rigs-in-traffic_100749686_h.jpg\" data-src=\"https:\/\/images.hgmsites.net\/lrg\/big-rigs-in-traffic_100749686_l.jpg\" data-src-l=\"https:\/\/images.hgmsites.net\/lrg\/big-rigs-in-traffic_100749686_l.jpg\" data-src-m=\"https:\/\/images.hgmsites.net\/med\/big-rigs-in-traffic_100749686_m.jpg\" data-src-s=\"https:\/\/images.hgmsites.net\/sml\/big-rigs-in-traffic_100749686_s.jpg\" class=\"lazy\"\/><\/p>\n<p>Big rigs in traffic<\/p>\n<\/div>\n<p>The NPR report cites\u00a0a fertilizer-industry trade group that claims using the material wouldn&#8217;t lead to radiation exposure beyond current EPA limits, and Chinese researchers that are &#8220;optimistic&#8221; about the ability of a new recycling process to remove radioactive material, with the caveat that more research is required.<\/p>\n<p>The EPA doesn&#8217;t allow use of\u00a0phosphogypsum in road construction, a policy that&#8217;s been in place almost continuously for 30 years (the ban was briefly lifted during the Trump administration).
