Abstract
The objective of the present study is to formulate added value polymer granite composite (PGC) based on granite (G) waste scraps as filler and unsaturated polyester (UP) obtained from chemically recycled post-consumed poly (ethyleneterephthalate) wastes (PET) as a matrix to be used in different candidate applications. Both wastes were collected from local dumping sites. Factors affecting the properties of the acquired PGC products e.g. polymer constitutions, granite/styrenated polyester ratios were studied systematically. The reached polymer granite composite has many advantages e.g. low density, very small water absorption percentage, short curing and hardening time, acceptable compressive strength values and significant thermal stability. Moreover, the environmental reward due to the utilisation of accumulation of the two problematic solid wastes is certainly a gain.
