I found a reference to a composite building product called Newwood, made using a lot of content from recycled plastic bags. Probably similar to several other mixed wood/plastic products out there, but seems to be marketed as a direct substitute for plywood.

Lots of testimonials on its weather resistance, but nothing about structural strength.

Anyone used this stuff in a real-life application?

Something like that might be nice as flooring over a basement slab, come to think of it… no moisture issues, in theory.
