CO2 could be used in 'green' plastic production

Excess carbon dioxide in the atmosphere has certainly become an environmental concern in recent years, but researchers from Germany’s Fraunhofer Institute for Environmental, Safety and Energy Technology are now experimenting with a process that uses CO2 to process plastic products in an environmentally-friendly fashion. They have discovered that by compressing the gas, it can be used to impregnate plastic objects with dyes, antibacterial compounds, or other substances. Traditionally, toxic solvents have been used for coloring plastic items.
