Sentences with phrase «into ethylene»

Natural gas liquids (NGLs) ethane and propane get extracted and sent to a «cracking facility» where ethane is made into ethylene (the foundation of polyethylene - the most common plastic in the world, frequently used for packaging, bottles, and synthetic clothing), and at a dehydrogenation plant, propane is made into propylene (the foundation of polypropylene - a plastic commonly found in food packaging and vehicle manufacturing).
