SAPAC's PU foam has a chemical inertion and can be eliminated through the domestic waste industry (Rest Wastes).The PU foam has got a high caloric value and therefor lends itself perfectly as a source of energy for combustion purposes after the recyling process. However in liquid form, the isocyanate can provoke allergies and respiratory problems. Therefor, SAPAC has invested in a vast park of refillable and completely closed bottles.
