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.
