Scientists turn bioplastic cutlery into building foam

New Zealand scientists have developed a method for converting biodegradable plastic knives, spoons, and forks into foam that can be used as wall insulation or in flotation devices.

Biodegradable plastics are specially designed to degrade quickly and cannot be recycled. Researchers at the University of Canterbury in New Zealand have developed a method for converting biodegradable plastic knives, spoons, and forks into foam that can be used as wall insulation or in flotation devices.

As an experiment, the scientists placed cutlery in a special chamber filled with carbon dioxide. By changing the level of pressure, the researchers observed how carbon dioxide expanded inside the plastic, creating foam, and later scientists received foam.

Every time plastic is recycled, it loses a little of its strength. But for foam, this is not important: in many applications, strength is not required from it. This material is used as wall insulation or in flotation devices.

Recycling biodegradable plastics can partially solve the global problem of environmental pollution. Although the biodegradable material eventually degrades in nature, it is better for the environment if the plastic is recycled.
