Recycled rubber storage

Recycled rubber from whole tires into chips and crumbs can generate heat up to 115 *C in the ambient grinding process. This can on storage without sufficient cooling lead to spontaneous combustion. The presence of iron in the natural rubber compounds can catalyze the oxidation process, causing rubber degradation. This degradation is accelerated with heat. During grinding processing generation of crumbs and storage, volatiles and hot fumes may be generated.

Thus the recycled rubber must be sufficiently cooled, either by water or air to avoid spontaneous combustion. Rubber crumbs should be stored at ambient temperature in dry areas but not in tin sheds or tin roof warehouses.
