    Abstract: A method for recycling EVA plastic foamed material may include steps of collecting excess plastic foamed compound; granulating through hot melt method; weighing and mixing granular plastic compound; rolling mixed compound into plastic film; and foaming plastic film to produce EVA foam mat. The excess plastic foamed compound can be recycled and reused in the present recycling method, which has environmental benefits and reduces the manufacturing cost. Also, the EVA foam mat, which is formed from the high-quality of the plastic film coupled between two unfoamed plastic mat bodies, has strong structural strength and prolonged lifetime, which prevents the EVA foam mat from deformation due to heavy pressure and protects the floor or tiles thereunder.
