Granulated (or recycled) Expanded Polystyrene (EPS) has many uses across many industries. It is ideal for use as particulate insulation in walls and ceiling cavities. Expanded Polystyrene is inert and non-toxic. It can also be used in landfill, helping to stabilize a site. Expanded Polystyrene promotes soil aeration and encourages plant growth on reclaimed sites. Expanded Polystyrene does not degrade, it does not form methane gas, nor will it leach substances into ground water.
