An apparatus and method for high pressure treatment of bulk material by extraction and/or impregnation may involve high pressure treating bulk material in a high pressure treatment volume of a pressure vessel apparatus at a high pressure level, especially high pressure in the range from 40 to 1000 bar. The method comprises at least the three following step sequences that are each controllable individually: pressurization, high pressure treatment, and depressurization. The high pressure treatment is performed in a continuous manner in the high pressure treatment volume. The high pressure treatment volume or the entire pressure vessel apparatus is in a fixed arrangement during the high pressure treatment. The continuity of the high pressure treatment is ensured solely by means of the high pressure treatment volume. This especially enables engineering optimization of high pressure treatment processes, for example extraction.

The present invention relates to a process for the production of ethylene-based polymers from waste plastics feedstocks comprising the steps in this order of: (a) providing a hydrocarbon stream A obtained by treatment of a waste plastics feedstock; (b) providing a hydrocarbon stream B; (c) supplying a feed C comprising a fraction of the hydrocarbon stream A and a fraction of the hydrocarbon stream B to a thermal cracker furnace comprising cracking coil(s); (d) performing a thermal cracking operation in the presence of steam to obtain a cracked hydrocarbon stream D; (e) supplying the cracked hydrocarbon stream D to a separation unit; (f) performing a separation operation in the separation unit to obtain a product stream E comprising ethylene; (g) supplying the product stream E to a polymerisation reactor; and (h) performing a polymerisation reaction in the polymerisation reactor to obtain an ethylene-based polymer; wherein in step (d): ⋅the coil outlet temperature is ≥800 and ≤870° C., preferably ≥820 and ≤870° C.; and ⋅the weight ratio of steam to feed C is >0.3 and <0.8. Such process allows for optimisation of the quantity of waste plastic material that finds its way back into a polyethylene that is produced as outcome of the process. The higher that quantity is, i.e. the higher the quantity of chemical building blocks that are present in the waste plastic material that are converted to the produced polyethylene, the better the sustainability footprint of the process is. The process allows for circular utilisation of plastics. In addition, the process allows for increased efficiency in the production of polyethylene in that the fraction of ethylene in the cracked hydrocarbon stream D is increased. A further advantage of the process of the present invention is that the overall energy consumption towards polyethylene is reduced.

The present invention provides an apparatus for manufacturing a mixture composition of organic and inorganic material and a method for manufacturing a mixture composition of organic and inorganic material using the apparatus, which can significantly increase the recycling rate of waste plastic or waste vinyl and minimize environmental pollution, by producing a block manufactured by effectively mixing organic polymers and inorganic soil.

In a process for recycling waste fabric comprising elastomeric material a polar solvent is flowed through the waste fabric in an extraction chamber to dissolve and remove the elastomeric material; the solvent is evaporated in an evaporation chamber and condensed to be sent to a solvent collection tank or back to the extraction chamber; the dissolved elastomeric material is eventually recovered from the concentrated polar solvent.

The invention relates to a pyrolysis method and reactor for recovering at least one component from a tire material using thermal decomposition. The tire material is delivered to a pyrolytic chamber (1), exposed to a controlled atmosphere and heated to a decomposition temperature of the at least one component in the pyrolytic chamber (1) by microwave radiation. A variable power microwave radiation at frequencies between 300 MHz and 2500 MHZ is applied to sequentially vary a temperature in the pyrolytic chamber (1) over a temperature range including the decomposition temperature of the at least one component.

A synthetic resin formulation can be made using a styrenic polymer created via the depolymerization of a polystyrene feedstock. In some embodiments the polystyrene feedstock contains recycled polystyrene foam. In some embodiments, the styrenic polymer has a molecular weight similar to virgin polystyrene. In some embodiments, the styrenic polymer has a higher molecular weight and reduces the amount of virgin polystyrene needed for a synthetic resin formulation. In some embodiments, the styrenic polymer has a lower molecular weight and increases the amount of recycled polystyrene that can be used in a synthetic resin formulation by increasing and homogenizing the melt flow of the recycled polystyrene. The synthetic resin formulation can be used to make expanded, extruded, and/or graphite polystyrene foam products, as well as rigid polystyrene and ABS products.
