“…Five different concrete samples (one neat concrete, one concrete with scrap rubber pieces and three concretes with waste PET bottle pieces) were considered. Thermal insulation performances of these samples were examined by the adiabatic hot-box technique, recently proposed by the authors [84]. The results revealed that proper addition of selected waste materials into concrete can significantly reduce heat loss or improve thermal insulation performance.…”

Abstract-In general, the quantity of plastics of all types consumed annually all over the world has been growing in a phenomenal way. The manufacturing processes, service industries and municipal solid wastes (MSW) generate numerous waste plastic materials. The increasing awareness about the environment has tremendously contributed to the concerns related with disposal of the generated wastes. It is believed that the management of solid waste is one of the major environmental concerns in the world. Due to limited space on landfills and increasing costs of plastics, utilization of waste plastics has become an attractive alternative for disposal. This paper provides a summary of experimental efforts on the utilization of poly(ethylene terephthalate) (PET) in civil engineering projects, mainly in road pavement, cements and concretes. Presented data indicate that use of waste PET for modification of asphalt, cement and concretes improved their selected properties, which makes economical this approach. Furthermore, using of waste PET in building materials reduce usage of new polymeric materials, which has significant effect on environment pollution (e.g. emission of carbon dioxide, waste disposal problems, etc.) Index Terms-Bitumen, building materials, concrete, PET, recycling.

“…Currently only 3.5% of generated polymeric products is recycled whereas these percentages for paper, glass and metals are, respectively, 34%, 22% and 30%. Bulent Yesilata and co workers studied the effect of waste PET addition on thermal transmission (or insulation) property of ordinary concrete and report that corresponding percentages for PET bottle pieces vary between 10.27% and 18.16%, depending on the geometries of added pieces [2]. Moreover, concrete-PET blends due to their ability in water absorption, a possible application could be in sports courts and pavements which need good water drainage [3].…”

Recycling of polyethylene terephthalate (PET) by aminolysis breeds environmental benefits. In this work Polyethylene terephthalate in the form of waste fibers were subjected to depolymerization through aminolysis using excess amount of ethanolamine in the presence of sodium acetate, as catalyst. Obtained product, bis (2-hydroxy ethylene) terephthalamide (BHETA) was in its pure form with sufficiently high yields. The purified product was characterized by FTIR, 1 HNMR and 13 CNMR spectroscopy as well as melting point determination. Since catalyst and raw materials have low price, synthesis of this material is economical and could be used as diol to synthesis of polyurethanes. In this search, polyurethanes have been synthesized based on BHETA, HDI and polyethylene glycol via prepolymer method. Termogravimetric analysis (TGA) and Differential scanning calorimetry (DSC) were carried out to study thermal stability, thermal transitions, T m and T g of synthesized polyurethanes. Effect of BHETA content in the main chain of synthesized polyurethanes on thermal stability of polyurethanes, strength and stiffness has been evaluated. BHETA based polyurethanes show Young's modulus about 300 MPa and elongation at break as 130% due to its aromatic structure.

“…Last few years waste rubber and mainly scrap tires were considered as one of the alternative energy sources (Stelmachowski & Słowiński, 2009. In addition grinded rubber waste and obtained granulate, fine rubber particles or rubber dust offer possibility for production of new composite materials with valuable properties -in (Aules, 2011;Sathiyamoorthy et al, 2011), for concretes with enhanced thermal insulation properties (Siddique& Naik, 2004;Yesilata et al, 2009), for sound insulation materials (Asdrubali, 2006) etc.…”
