The invention comprises methods of robotically separating unwanted heteroatom-containing materials from a plastic mixture and catalytically pyrolyzing the resulting mixed plastics to obtain olefins and aromatics. Systems and compositions useful in the catalytic pyrolysis of plastics are also described. L'invention comprend des procédés de séparation robotisée de matériaux contenant des hétéroatomes indésirables à partir d'un mélange plastique, et de pyrolyse catalytique des matières plastiques mélangées résultantes pour obtenir des oléfines et des composés aromatiques. L'invention concerne en outre des systèmes et des compositions utiles dans la pyrolyse catalytique de plastiques.
