Eastoe and Oliveira\u2019s concern about the impact of plastic debris, also called white pollution, on the health of our ecosystems drove this study.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cWe were interested to see if we could find a way to repurpose plastic waste,\u201d Eastoe said. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The environment is also being harmed by synthetic dyes and other hazardous substances that are continually being leaked into our water supply. Many of these pollutants are causing significant damage to aquatic ecological systems.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThe development of methods of removing these compounds from industrial effluents is becoming increasingly important,\u201d Eastoe said in a statement. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cOur study both looks at the reuse of plastic to make a new material and the use of this material to tackle water pollution from dyes,\u201d he continued. \u201cThis breakthrough will be of interest to water companies worldwide and the next stage will be to see how it might clean-up other pollutants.\u201d<\/span><\/p>\n<h2><b>How it Works<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">In their study, the scientists broke down dyes by using active oxidation process. This process involves a heterogeneous (solid-state) photocatalyst, which helps to turn pollutants into less harmful products, such as water and carbon dioxide. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The method involves transforming polystyrene into a porous solid material.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To accomplish this goal, the researchers first had to dissolve lumps of plastic in a cyclohexane solvent, said Eastoe. They then froze the solution and removed the solvent using a vacuum. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThis leaves behind a highly expanded plastic,\u201d comparable to packing foam, explained Eastoe. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">The light and strong material created from polystyrene is then activated by using catalytic nanoparticles, he continued. \u201cNow the activated material can be used to break down pollutant dyes using light to trigger the degradation.\u201d<\/span><\/p>\n<figure id=\"attachment_23473\" aria-describedby=\"caption-attachment-23473\" style=\"width: 860px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"size-full wp-image-23473\" src=\"https:\/\/www.tun.com\/blog\/wp-content\/uploads\/2018\/03\/plastic.jpg\" alt=\"\" width=\"860\" height=\"545\" srcset=\"https:\/\/www.tun.com\/blog\/wp-content\/uploads\/2018\/03\/plastic.jpg 860w, https:\/\/www.tun.com\/blog\/wp-content\/uploads\/2018\/03\/plastic-300x190.jpg 300w\" sizes=\"(max-width: 860px) 100vw, 860px\" \/><figcaption id=\"caption-attachment-23473\" class=\"wp-caption-text\">Image: University of Bristol<\/figcaption><\/figure>\n<p><span style=\"font-weight: 400;\">The method will likely be used to break down dyes such as Rhodamine B, a dye banned in food production but often used to detect leaks in sewage treatment plants. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A team of researchers has developed a method to re-use common plastics to break down other harmful pollutants found in wastewater.
