Abstract: A storage tank that stores sulphur with zero emissions uses reinforced EPS panels and an impermeable bottom. The reinforced EPS panels are reinforced with networks of horizontal and/or vertical galvanized or stainless steel wires that are interconnected by galvanized or stainless steel orthogonal wires.
