Abstract
Abstract In this study, an alternative method for recycling residues of labels and stickers (parings) containing biaxically oriented polypropylene (BOPP) and polyurethane-based glue was discussed. The recycling of this type of material is complicated, once the separation and the milling processes are difficult to be accomplished, due to the presence of a large amount of glue. In this study, sugarcane bagasse ash was used to enable the milling process of stickers residues. Composites were prepared with post-consumer polypropylene extrusion with different polypropylene/parings ash ratio. These materials were analyzed by tensile, three point flexural, hardness, density, water absorption, Izod impact tests, thermogravimetric analysis, environmental exposure and scanning electron microscopy. Addition of sticker residues/ash to the polypropylene matrix makes the material more rigid and does not affect significantly thermal and degradation properties. Thus, the recycling process proposed in this paper is environmentally and economically viable.

Labels and stickers play the role of providing information are: rinsing water, bagasse, leaves, sugarcane tips and ash, on products, in order to attract the consumer, give information vinasse, filter cake and yeast

The sugarcane ashes have previously been characterized[1], showing that the CBCA is basically constituted of silica grains, with sizes varying between 10 and 400 μm, containing 14% of organic matter, referent to the remaining carbonized sugarcane fibers, and 2% of moisture
Summary
Labels and stickers play the role of providing information are: rinsing water, bagasse, leaves, sugarcane tips and ash, on products, in order to attract the consumer, give information vinasse, filter cake and yeast. Power to the national system, by means of cogeneration. When those labels and stickers are produced, many parts of them are cut out; the remaining material is called “parings” by the printing industry. Those adhesive parings are not recycled or reused; they are kept in the factories or are inconsequently thrown away on dumps.
