1. A method for producing hydrocarbons from polymer-based waste, wherein the method comprises:
arranging a gasifier in parallel with at least one cracking unit, wherein the gasifier is a fluidized bed gasifier;
supplying polymer-based waste to the gasifier and gasifying the polymer-based waste with steam at a temperature of 640-750° C. and at a pressure of below 4 bar in the gasifier for forming a product mixture comprising at least olefins;
supplying raw material to a cracking device of the cracking unit and producing a hydrocarbon mixture comprising olefins from the raw material in at least one cracking unit; and
supplying the product mixture of the gasifier and the hydrocarbon mixture of the cracking unit to a recovery unit of the hydrocarbons for separating at least one hydrocarbon fraction.
