Abstract: A method of recycling plastics, using a polyolefin feedstock from reclaimed plastic, in which a solution is created of at least one polymer of the feedstock in at least one solvent by dissolution in a reactor vessel, one or more contaminants are removed from the solution, the solvent is separated from the polymer and the polymer extruded for re-use, wherein a chain extender is introduced to the solution to modify the properties of the polymer in the solvent and increase its use in secondary applications. Embodiments are described using a peroxide in a solution of PE and butylal or xylene, colour pigments are filtered out and the solution is fractionated by polymer molecular weight selectively before and after the peroxide is added. The method lends itself to commercial scale processing with reactor vessels of 1,000 litres and greater by use of a fast dissolution reactor.

Abstract: The present invention relates to the fields of life sciences, micro- organisms and degradation of hydrocarbon chains such as polyolefins. Specifically, the invention relates to an isolated specific enzyme or a fragment thereof, wherein said enzyme or fragment is a superoxide dismutase and is capable of degrading a hydrocarbon chain or a polyolefin, and to a micro-organism or a host cell comprising the enzyme or a fragment thereof. Also, the present invention relates to a polynucleotide encoding the enzyme or fragment thereof, and to an expression vector or plasmid comprising the polynucleotide of the present invention. And still, the present invention relates to use of the enzyme, fragment, micro-organism, host cell, polynucleotide, expression vector or plasmid of the present invention for degrading a hydrocarbon chain such as a polyolefin; to a method of degrading a hydrocarbon chain such as a polyolefin with the specific superoxide dismutase enzyme or a fragment thereof; and to a method of producing the enzyme or fragment thereof of the present invention.

Abstract: Catalytic compositions for depolymerizing polyolefin-based waste material into useful petrochemical products and methods of use are described. The compositions are a composite of at least one zeolite catalyst with one or more co-catalyst(s) that is a solid inorganic material. These composite catalysts, along with heat, are used to both increase the depolymerization reaction rate of the feed streams and suppress poisoning effects of non-polyolefin polymers that may be present. This results in a shorter residence time in the depolymerization unit and more efficient process.

Abstract: Um ein Flächenmaterial bereitzustellen, welches möglichst stabil ist und sich möglichst einfach herstellen lässt, wird vorgeschlagen, dass das Flächenmaterial ein thermoplastisches Polymermatrixmaterial umfasst, in welchem ein Fasermaterial aufgenommen ist, wobei das Fasermaterial Fasern umfasst oder aus Fasern gebildet ist, welche zumindest näherungsweise parallel zueinander angeordnet sind, und wobei ein Anteil des Fasermaterials an dem Flächen- material bei ca. 75 Gew.-% oder mehr liegt, bezogen auf eine Gesamtmasse des Flächenmaterials.
