An integrated process for the manufacture of olefins and intermediates for the production of ammonia and urea, comprising an FCC reactor, a regenerator, a steam reforming unit, an air-separation unit, an ammonia production unit and a urea production unit, is described. This process makes it possible to minimize CO2 emissions to atmosphere, make use of heavy feedstocks of low added value (AR) for the production of light olefins, in addition to making maximum use of all the flows involved, thus increasing the energy efficiency achieved, all at the same time.
