Researchers have demonstrated it is possible to economically produce plastics that have a net-zero greenhouse gas emissions balance over their entire life cycle. And they may cost less, too.
Since the early 1950s, plastics have found their way into almost every area of modern life. Between 1964 and 2014, plastic consumption increased twenty fold, from 15 to 311 million tonnes (around 16.5 to 342.8 million tons) per year.
Not only has environmental pollution from plastic waste increased during this time, but the amount of petroleum its manufacture consumes is large, as are the associated greenhouse gas emissions.
Now, researchers have created a new computational model of global plastic production and disposal that combines three technologies that already exist: plastic recycling and plastic production from biomass and from CO2 through carbon capture and utilization (CCU).
As the calculations showed, the key is to use as much recycled plastic as possible, supplemented by the other two manufacturing methods. These three types of manufacturing correspond to the principle of the circular economy.
By optimally combining the three technologies, the quantity of energy required can be reduced by 34% to 53% compared with the current fossil-based manufacturing practice, supplemented with extensive carbon capture and storage (CCS)—particularly in waste incineration plants, where plastic products are burned at the end of their life cycle.
The cost of the newly proposed manufacturing method is on a par with that of this alternative fossil manufacturing scenario. Under favorable conditions, by 2050 the cost of global plastic production can be reduced by as much as $288 billion per year compared to the alternative scenario.
