Abstract
A polyphenylene ether group resin composite can comprise: polyphenylene ether group resin, flame retardation reagent, and recovered polystyrene group resin. The recovered polystyrene group resin can be recovered using limonene or thermal shrinkage recovery, and can comprises polystyrene that has been recovered from a product or a part of a product that has been used by an end customer for a period of time.

A polyphenylene ether group resin composite, comprising:
- polyphenylene ether group resin;
- flame retardation reagent;
- and
- recovered polystyrene group resin recovered using limonene or thermal shrinkage recovery, wherein the recovered polystyrene group resin comprises polystyrene that has been recovered from a product or a part of a product that has been used by an end customer for a period of time.

A method for making an article, comprising:
- dissolving a polystyrene group resin product that has been used as a product by an end customer for a period of time in a terpene group material;
- recovering polystyrene group resin from the polystyrene group resin product;
- melt blending the recovered polystyrene with polyphenylene ether group resin, 0.1 to 50 parts by weight flame retardation reagent, 0.01 to 5 parts by weight poly tetrafluoroethylene, and 0.1 to 70 parts by weight additive, wherein the parts by weight are based upon a total of 100 parts by weight of polyphenylene ether group resin, recovered polystyrene group resin and any virgin polystyrene group resin, and wherein the additive comprises at least one material selected from the group consisting of rubber substance, fiber form filler, non-fiber form filler, olefin group polymer, alicyclic saturated hydrocarbon resin, higher grade fatty acid ester, terpene variety, waxes, petroleum hydrocarbon variety, aromatic hydrocarbon group petroleum resin, polyoxy alkylene, fluorine group resin, antistatic reagent, ultraviolet rays absorption reagent, and pigment;
- extruding the blend;
- and
- molding the extruded blend to form an article.
