04 Jan 2024 --- Researchers have developed a cushioning foam from cardboard waste. Their upcycled material is reportedly stronger and more insulating than traditional, plastic foam-based cushioning. Waste paper is one of the most common kinds of waste accumulated domestically. Newspapers and junk mail, but also paperboard envelopes and cardboard boxes can often be found in abundance, as e-commerce shopping continues to be popular. The researchers wanted to turn these containers and paper waste into sturdy but light mailing materials. Currently, to keep electronics and toys nestled tightly inside a box, molded cushioning materials, such as styrofoam, are typically used.
