Provided are a composition for swelling pretreatment of a cured thermosetting resin material before decomposition, including a surfactant and an acidic material, and a method for swelling pretreatment of a cured thermosetting resin material before decomposition by using the same. When carrying out swelling pretreatment of a cured thermosetting resin material before decomposition by using the composition, it is possible to accelerate infiltration of the acidic material into the cured thermosetting resin material and swelling of the cured thermosetting resin material by virtue of the surfactant, and thus to increase the decomposition reactive surface area. Therefore, it is possible to increase reaction efficiency during the subsequent decomposition process, and to increase the decomposition ratio during the same period of time.

The present invention relates to a process for the catalytic decomposition of a polyolefin. More particularly, the present invention relates hydrocarbon-aided catalytic decomposition of a polyolefin using an aluminosilicate.

The present invention relates to a process for recycling solid waste from vulcanized elastomers based on sulphur or crosslinked with peroxides. In this context, the present invention proposes the recycling of said waste by means of radical de-crosslinking in the presence of ozone and de-crosslinking agents, without the use of high temperatures. The present invention also relates to recycled elastomers and the use of said recycled elastomers obtained by means of said process.
