MUMBAI, India, March 14 -- Intellectual Property India has published a patent application (202617010961 A) filed by Next Generation Recyclingmaschinen Gmbh, Feldkirchen an
der Donau, Austria, on Feb. 2, for 'method for processing plastic waste.'
Inventor(s) include Wolf, Sven; and Hackl, Andreas.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to a method for processing plastic waste. The method comprises providing plastic waste material with a proportion of thermoplastics of at least 50 wt. %, heating and melting the plastic waste material by means of a single-shaft single-screw extrusion device, separating non-melted solid matter from the plastic material melt by means of the filtration device and heating the filtered plastic material melt further by means of a multi-shaft extrusion device. After the further heating, the filtered plastic material melt is transferred by means of the multi-shaft extrusion device to a continuous pyrolysis furnace reactor and is pyrolysed in said continuous pyrolysis furnace reactor at a pyrolysis temperature. Before transfer to the continuous pyrolysis furnace reactor, the filtered plastic material melt is heated by means of the multi-shaft extrusion device to a discharge temperature which is 50 C lower to 20 C higher than the pyrolysis temperature in the continuous pyrolysis furnace reactor."
The patent application was internationally filed on July 16, 2024, under International application No.PCT/AT2024/060278.
