It is our duty as scientists to ensure we leave them with the best possible environment,\u201d Aida said.<\/p>\n<p>Aida said the new material is as strong as petroleum-based plastics but breaks down into its original components when exposed to salt. The components can then be further processed by naturally occurring bacteria, thereby avoiding generating microplastics that can harm aquatic life and enter the food chain. As salt is also present in soil, a piece about 5cm in size disintegrates on land after over 200 hours, he said.<\/p>\n<p>The material can be used like regular plastic when coated, and the team are focusing their research on the best coating methods, Aida said. The plastic is non-toxic, non-flammable and does not emit carbon dioxide, he said.<\/p>\n<p><strong>For More News And Analysis About <span style=\"color: #ff6600\">South-Africa<\/span> Follow <span style=\"color: #ff6600\">Africa-Press<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; South-Africa.
