Scrap tires are not considered harmful waste, but their stocking and disposal are a potential health and environmental risk. Properly controlled calcinations at high temperatures make tire combustion an interesting alternative due to its high calorific power, comparable to that of fuel-oil. Consequently, using them as an alternative combustible material in cement kilns makes it possible to give it a valuable use. However, it remains to be assured whether the impurities added to the clinker through these fuels do not affect its structure or properties.This paper shows the studies carried out on different clinkers under laboratory conditions with different levels of addition of scrap tire ashes, added by partially replacing traditional fuel in cement kilns.

“…Elastomers such as natural rubber (NR), styrene-butadiene rubber (SBR), and ethylene propylene diene monomer rubber (EPDM) have low microwaves absorption due to their non polar characteristic. This limitation can be overcome by the addition of conductive filler like carbon black [8][9][10] .…”

Blends of ground tire rubber devulcanized by microwaves/HDPE - Part A: influence of devulcanization process

et al. 2015

SbstractThe main objective of this work is the study of the influence of microwaves devulcanization of the elastomeric phase on dynamically revulcanized blends based on Ground Tire Rubber (GTR)/High Density Polyethylene (HDPE). The devulcanization of the GTR was performed in a system comprised of a conventional microwave oven adapted with a motorized stirring at a constant microwaves power and at various exposure times. The influence of the devulcanization process on the final properties of the blends was evaluated in terms of mechanical, viscoelastic, thermal and rheological properties. The morphology was also studied.

“…Three products are derived from pyrolysis: gas with a high calorific value, pirolytic oil that can be used as fuel or as a source of benzene, toluene, xylene (BTX) or limonene and char that can be used as fuel, activated carbon or carbon black [2][3][4][5][6][7].…”

“…Styrene butadiene (SBR), polybutadiene (BR), nitrile (NiR) and chloroprene rubbers together with natural rubber (NR) are the main constituents of tyre crumbs [5,[7][8][9]. Their chemical structure with aromatic and aliphatic constituents plays an important role in determining the composition of the oils derived from tyre crumbs.…”
