Systems and methods for recycling waste plastics are provided, including a system for recovering styrene monomer from waste polystyrene. The system includes a mixing, heating and compacting apparatus to receive a supply of waste polystyrene and to output a densified polystyrene containing melt; a pyrolysis reactor configured to receive the densified polystyrene containing melt and a supply of recycled oligomers, pyrolyze the densified polystyrene containing melt and the recycled oligomers, and output a hydrocarbon gas stream and a solids residue stream; a quenching apparatus configured to receive the hydrocarbon gas stream output from the pyrolysis reactor and condense out oligomers for routing upstream to the pyrolysis reactor to be combined as the supply of recycled oligomers with the densified polystyrene containing melt, and to discharge an altered hydrocarbon gas stream for further processing; and a condenser configured to receive the altered hydrocarbon gas stream from the quenching apparatus and condense out styrene to form a styrene monomer oil product.

A feed device of a pyrolysis apparatus and a feed method through which material processed in the pyrolysis apparatus, such as plastic and/or rubber waste, can be fed into the pyrolysis apparatus. In the feed device there is a feed opening for the material to be processed, a feed chamber, closing members in conjunction with the feed chamber and a discharge opening, through which the material to be processed can be conveyed to the pyrolysis apparatus's pyrolysis chamber. A vacuum pump has been adjoined in conjunction with the feed device's feed chamber to achieve a vacuum or sufficient underpressure in the feed chamber after the material to be processed has been fed into the feed chamber and the feed chamber's closing members have been closed. After the closing member of the feed chamber's discharge opening has been opened, the material to be processed, from which the oxygen harmful to the pyrolysis process has been removed, is conveyed into the pyrolysis chamber.

An apparatus for distillation of feedstock, including a distillation chamber with an inlet for receiving feedstock and an outlet for discharging feedstock, and a plate for supporting the feedstock in the distillation chamber. The plate is positioned parallel to a substantially horizontal plane across a portion of the distillation chamber, and defines a plurality of transverse apertures extending transversely across a substantial portion of the width of the plate. A plurality of heating rods is included for insertion into the apertures of the plate to heat the plate. The apparatus also includes a conveyor enclosed within the distillation chamber and extending longitudinally across the distillation chamber, the conveyor having a plurality of paddles attached thereto that, when driven by the conveyor, move proximate and parallel to the plate to agitate feedstock on the plate, and to drive the feedstock from the inlet to the outlet of the distillation chamber.

A sealed portable industrial furnace for optimizing the concurrent production of charcoal, fuel gas, pyroligneous extract and tar includes an upright metallic body for receiving wood or biomass. A cover is mounted to the upper end of the upright body and the pressure relief system is incorporated into the cover. A perforated base structure is attached to the lower end of the upright body, and a discharge valve is incorporated into the base structure and is closed during production of the charcoal and then is opened to unload the charcoal produced. A support skirt encircles the base structure to support the body in upright position and defines an expansion chamber for the accumulation of combustion gases generated by the furnace. A series of inlet openings are located along the height of the upright body through which combustion air may be introduced under the action of a control system which receives temperate data from temperature monitoring devices located along the height of the body.

A system and method for plasma arc anaerobic thermal conversion processing is provided to convert waste into bio-gas; bio-oil; carbonized materials; non-organic ash, and varied further co-products. The system and process supports a variety of processes, including to make, without limitation, carbon, carbon-based inks and dyes, activated carbon, aerogels, bio-coke, and bio-char, as well as generate electricity, produce adjuncts for natural gas, and/or various aromatic oils, phenols, and other liquids, all depending upon the input materials and the parameters selected to process the waste, including real time economic and other market parameters which can result in the automatic re-configuration of the system to adjust its output co-products to reflect changing market conditions. Plasma arc carbonizer off-gases produced during carbonization are supplied to a controlled heated column for refining and recovery of the carbonizer hot gases into distillates.
