Most plastics are made from petrochemicals, meaning they consume too many fossil feedstocks in their production.
Only 4% of the world’s fossil resources are used in plastic production and only 1.5% of the oil extracted in the world is used for the production of plastic packaging. However, in the long term, the vast majority of plastics will be produced from alternative feedstocks, such as recycled oils or secondary plastics, responsibly sourced biomass, or even CO2.
