I'm glad that all of the makers of 3D printers are going green and coming up with ways that allow 3D printer owners to use recycled waste plastic and turning them into the plastic filaments used for 3D printing objects.

This allows 3D printer owners to reuse their waste plastic instead of buying spools of plastic filaments.

Some 3D printer manufacturers are already demonstrating the the ability to just take any plastic object such as a bottle cap, and then grind it up for use as 3D printing material like in this video.
