Abstract: A method for manufacturing a toy building element includes providing an acrylonitrile butadiene styrene (ABS) waste material, screening the ABS waste material for at least one property indicative of regulatory compliance and/or polymer morphology, and recovering recycled ABS polymer from the screened ABS waste material by grinding and/or a solvent dissolution recycling process. A resin is obtained by mixing the recovered recycled ABS polymer optionally with one or more additives and optionally with one or more additional polymers selected from additional ABS polymers, styrene-acrylonitrile (SAN) polymer, and butadiene or butadiene-containing polymer. The toy building element is manufactured by processing the resin. In some embodiments, screening evaluates CMR substances, metal migration limits, butadiene-to-SAN ratio, butadiene sphere size distribution, and/or butadiene sphere crosslinking.

Abstract: The present disclosure relates to a toy building element made of a polyester material and manufactured by processing of a resin comprising at least one polyester, at least one reactive impact modifier and at least one non-reactive impact modifier. The present disclosure also relates to a method for the manufacture of such toy building element.

Abstract: A toy building element made of recycled Acrylonitrile Butadiene Styrene (“ABS”) material and manufactured by processing, of a resin comprising, mechanically recycled ABS polymers and/or chemically recycled ABS polymers recovered from a solvent dissolution recycling process. A method for the manufacture of a toy building element includes providing and screening an ABS waste material. The method includes recovering recycled ABS polymers from the screened ABS waste material by subjecting the ABS waste material to grinding and/or a solvent dissolution recycling process. The method includes obtaining a resin by mixing the recovered ABS polymers with one or more additive(s) and optionally one or more ABS polymers selected from the group consisting of virgin ABS polymers, chemically recycled ABS polymers recovered from pyrolysis and chemically recycled ABS polymers recovered from chemical depolymerisation. The method thereafter includes manufacturing the toy building element by processing the resin.

Abstract: The present invention relates to toy building elements made of a biopolymeric material. The present invention also relates to a method of manufacturing said toy building elements.
