4、ial applications in modern society.Key packaging applications support the medical and food storage services needed for populous urbanized life.Beyond packaging,plastics are used in buildings,water system infrastructure,transportation,machinery,clothing,electronics,and other consumer goods.They are a

5、lso fundamental to the construction capital equipment needed for a net-zero energy transition,such as solar panels and electrical wiring.The plastics sector is a major component of the broader petrochemical sector and source of greenhouse gas(GHG)emissions.The petrochemical industry accounted for 14

6、%of the total primary demand for oil in 2019 by volume.Converting oil and gas feedstocks to plastics directly emits 1.41.6 Gt COe/y and managing petrochemical waste emits another 0.2 Gt CO2e/y.1 Most primary production methods rely on fossil fuels for both material feedstocks and conversion energy.P
