2. Energy recovery
Rubber objects have an interesting calorific value. If we consider tires, three tons of product have the same calorific value as two tons of heavy fuel oil (lecaoutchouc.com). There are, however, a few limitations.
halogen content must not exceed 2%, which limits the incineration of polychloroprene (rubber made from a chlorinated monomer).
Incineration is of particular interest to ELT. According to data published by Aliapur by 2022, 49% of ELT will be recycled into energy.
Most of this recovery is carried out in cement works, where in some cases the rate of incorporation can be as high as half the quantity...
