   Total SE said Thursday that it would invest more than 500 million euros ($584.1 million) to convert its Grandpuits refinery in France into a zero-crude platform for biofuels and bioplastics. 


  The French energy company said crude refining at the platform will be discontinued in the first quarter of 2021, while storage of petroleum products will cease in late 2023. 


  The platform will be refocused on the production of renewable diesel, bioplastics, plastics recycling and the operation of two photovoltaic solar plants. 


  Service stations and airports in the Greater Paris region won't be affected, according to the company, as they will be supplied by other Total refineries.
