CHARACTERIZATION OF A CARDBOARD RECYCLING FACILITY'S PLASTIC WASTE FOR BENEFICIAL USE
An issue with old cardboard container (OCC) recycling is the generation of a plastic waste that currently either gets land-filled or burned. A Wandel screen, a common process unit, generates 35% of overall rejects that contain 75% of the facility's total plastic output. Plastic-rich Wandel wastes …

Temporary shelter for the homeless
A one-person cardboard structure was designed to temporarily shelter the homeless during harsh weather conditions. The overall form is based on the folding Yoshimura pattern. It is collapsible, wind and water resistant, and structurally rigid. The design is a prototype made from commonly available …

Incandescent molecules: An analytical investigation into materiality in contemporary abstract painting
… The expansive picture plane begins as a sheet of cardboard. By combining textural surface with carefully chosen colours, the cardboard sheds its humble beginning to become an art object. This is no mean feat. The surface eventuates from layers of sealants, gesso, and paint to which texture is …
