摘要：Plastics Waste cause serious environmental pollution and depletion of landfill space .This study includesrecycling of consumed transparent water bottles made from polyethylene terephthalate (PET) to prepare materials withproperties valid for use in some construction field. This study includes preparing first set of recycled polyethyleneterephthalate (RPET) with different melting temperature (180°C ,200°C ,220 °C , 240 °C) and mixing times(10,20,30,40,50 and 60 min) .50 minutes mixing time was chosen for mixing time .The second set of RPETcomposites filled with different weight Percentage of sawdust wood ( 10% , 20% ,30% , 40% , 50% and 60%).Weight percentage 30% of sawdust wood was chosen for RPET/S.D.W composites. Samples for physical tests (thermal conductivity and water absorption ) for the first set of RPET and RPET/S.D.W composites were prepared .Eight samples (A , B , C , D , E, F, G , H ) from RPET and RPET/S.D.W composites were prepared for thermalconductivity test . The results showed that the lowest thermal conductivity values 0.10 W/m.k was found for sample Aand 0.11 W/m.k for sample E of RPET and RPET/S.D.W composites at melting temperature 180°C . Eight samples(I , H , K , L , M , N , O, P ) for RPET and RPET/S.D.W composites were prepared for water absorption test . Lowestwater absorption value 0.76 was observed after 92 days immersion in water for Sample I prepared from RPET at180°C .It is concluded that RPET samples prepared at 180°C show best results for thermal conductivity and waterabsorption tests.
