    摘要： A method for preparing a fraction of sorted plastic waste in at least one first container (10), and a recycling plant for carrying out the method are provided. The method comprises a step of pre-processing of multifractional plastic waste by sorting the plastic waste into at least a first fraction and a second fraction according to physical, chemical and/or optical properties of the plastic waste by a sorting unit. The method comprises a step of filling at least a part of the first fraction through an inlet (11) of a first container (10) by a first filling unit (112, 1111) at a container filling position, a step of mono-fractionally storing the part of the first fraction in the first container (10) at an intermediate storing position, and a step of mono-fractionally post-processing the part of the first fraction by at least one post-processing unit.

    摘要： The present invention relates to a polymerization reactor assembly, comprising a reactor having a housing and an inner space, the reactor comprising at least one inlet, at least one outlet, a draft tube having a substantially cylindrical shape and an inner space, wherein the draft tube is located within the inner space of the reactor so that an upper opening and a lower opening of the draft tube are fluidly connected with the inner space of the reactor, and a stirrer comprising a top plate located above the lower opening of the draft tube, a stirrer blade having a helical shape, which surrounds the draft tube, wherein the axis of the draft tube and the axis of the stirrer blade are coinciding, the stirrer blade extending concentrically with respect to the draft tube and the housing of the reactor, and a bottom plate located below the lower opening of the draft tube, wherein the inner space of the reactor comprises sections A, B, C, and D, wherein section A is the space defined by the housing of the reactor and an upper surface of the top plate, section B is the space defined by the housing of the reactor, the draft tube, a lower surface of the top plate and an upper surface of the bottom plate, section C is the space defined by the housing of the reactor and a lower surface of the bottom plate, and section D is the inner space of the draft tube, wherein the top plate has at least one first opening fluidly connecting section A and section B, wherein the bottom plate has at least one first opening fluidly connecting section B and section C, wherein the bottom plate has at least one second opening fluidly connecting section C and section D, and wherein the stirrer is rotatable around the draft tube and inside the housing of the reactor. The present invention further relates to a process for polymerization of at least one alpha-olefin monomer using the above reactor assembly.
