MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202647087625 A) filed by D&g Recycling Gmbh on July 17, 2026, for Method And Device For Separating Particles Made Of Different Plastics.
Inventors include Deinert, Jrgen; and Gtz, Andreas.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: The aim of the invention is to separate particles (6) made of different plastics. This is achieved in that the particles (6) are suspended in a first liquid (10) with a first density and are separated into first light particles (11) with a lower density and first heavy particles (12) which have at least the first density. The first heavy particles (12) are dried and are then separated at least into a first fraction (21) and a second fraction (22) by means of a first electrostatic separation (19) on the basis of the dielectric properties of the particles. The particles of the second fraction (22) can be electrostatically charged, and the particles of the first fraction (21), on the basis of the dielectric properties thereof, are not charged or are charged differently than the electrostatically chargeable particles of the second fraction (22). The particles of the second fraction (22) are then suspended in a second liquid (25) with a higher second density and are divided into second light particles (27) with a lower density and second heavy particles (28) which have at least the second density. The second light particles (27) are dried and are then separated into at least two other fractions (34, 35) by means of a second electrostatic separation (32) on the basis of the dielectric properties of the particles.
