The use of recycled materials reduces the need for primary materials and it also minimizes the amount of waste in the production process. Therefore, by using recycled materials, the total material flow necessary for the production of a product can be reduced. Moreover, the total consumption of resources for the production of recycled material is, usually, remarkably inferior that in the product...

In this work, monopolymer blends of virgin polypropylene and photo-oxidized were prepare characterized. The samples subjected to accelerated ageing simulate the effects outdoor exposure polypropylene. After exposure, pelletized mixed with same polymer. rheological, mechanical morphological characterization was conducted on both polymers blends. Both viscosity properties decrease increases in co...

Abstract The increasing generation of plastic wastes forces us to search for final disposal technologies environmentally friendly such as pyrolysis, which becomes an interesting technique because it takes advantage the obtaining important products. In addition, catalytic pyrolysis by using commercial catalysts, e.g. zeolites, alumina or recovered from other industrial processes, allows decrease...
