Helping to save the Earth one pad at a time! Hartz® Clean Earth™ Biodegradable Training Pads are uniquely designed to contain materials that do not harm the environment and are still more absorbent than leading training pads. The training pads have both a tear resistant film backing and super-absorbent core materials that are biodegradable. The pads are packed in a corrugate carton made of recyclable and biodegradable material to ensure complete earth friendly disposal.
