A research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics - of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure.

CCS is technology that can capture and transport this CO2 and store it safely under the earth?s surface. Many have therefore begun to refer to CCS as carbon recycling, since the plan is to return the CO2 to where it came from, underground, for example in old, stable oil reservoirs that can be sealed.
