Soft plastics are the scrunchable bread wrapper, typical wrappings that you'd get on pre-packaged foods. It's also used in a lot of industrial purposes like wrapping pallets. The soft plastics we knew would be something that we could quickly get to the bottom of and replicate the performance characteristics that we see in our high-value bitumens that we use to construct or to add to our asphalt. So we'd been looking at all different types of plastics and we were having some troubles trying to get the performance characteristics out of traditional PETs and harder plastics. And so we knew that these soft plastics didn't really have much of an outlet and were being collected in a clean source through supermarket collection schemes, and so we thought we've got a very ready source that seems to be not doing a lot. And we worked with some of our existing partners to come up with Reconophalt.
