In a world first, scientists at the National University of Singapore have figured out a way to successfully convert plastic bottle waste into aerogels. The new lightweight material has a range of uses including environmental remediation and firefighting. One advantage of the product is its ability to absorb oil as much as seven times more effectively than other commercially available products. And when coated with fire retardant chemicals, the aerogel withstood temperatures up to 620 degrees celsius. The findings are published here.
