Abstract: A process for conditioning waste materials containing at least one waste material plastic, includes the steps of mixing the waste material to form a homogenous plurality of particulate waste material members; and, blending the homogenous plurality of particulate waste material members with a thermosetting blend resin and a cross-linking catalyst to form a blend. The waste material plastic forms ionic bonds with the thermosetting blend resin. A filled plastic product according to the invention includes a thermosetting resin matrix, and a filler material having a plurality of particles containing at least one component selected from the group consisting of heavy metals and filler plastics. The filler resins are selected from the group consisting of thermosetting materials and thermoplastic materials, and mixtures thereof.
