This video describes an experimental 3D printing process of turning scrap cardboard into pulp and using a 3D printer to form it into virtually any dense three-dimensional shape.

This gets into the dream of the 3D printer being the ancestor of the replicator from the Star Trek franchise. It makes sense to want to recycle materials at home. It already takes a huge amount of energy for materials to be created, shipped to a factory, processed into goods, shipped out to stores and then being brought home by the consumer. Hauling materials to a recycling center uses even more energy. Being able to recycle at home would create less waste and have less of an impact on the environment.
