Researchers have developed a process to convert discarded polystyrene into carbon sponge material that can capture carbon dioxide from the atmosphere. The technology represents an approach to address climate change by repurposing waste materials for environmental benefits.

The development involves upcycling polystyrene, commonly known as styrofoam, which is typically difficult to recycle through conventional methods. By transforming this waste material into a carbon sponge, researchers have created a dual environmental benefit of waste reduction and carbon capture.

Separately, Singapore has reportedly implemented climate technologies that draw from 19th-century methods, though specific details about these approaches were not available in the provided sources.

The carbon sponge material created from polystyrene could potentially be used in various applications for atmospheric carbon dioxide removal, contributing to efforts to reduce greenhouse gas concentrations in the atmosphere.
