Nanotechnology as potential method for recycling of PET bottles
Kráčalík, Milan ; Mikešová, Jana ; Pospíšil, L. ; Fortelný, Ivan ; Šimoník, J.
Recycling of PET worldwide is not sufficient. This issue results from decreasing molecular weight due to thermal, mechanical and hydrolytic degradation during multiple processing of polymer. The viscosity (next processability) of material can be increased by preparation of nanocomposites (formation of physical network in the polymer/clay system). The improved processing and utility properties of recycled PET were analyzed by rheology, morphology and tensile tests.
Use of compatibilization in recycling of commingled plastic waste
Starý, Zdeněk ; Kruliš, Zdeněk ; Beneš, Hynek
An efficient compatibilization system based on the combination of styrene-butadiene block copolymer (SBS) with ethylene-propylene random copolymer (EPM) has been developed for polyolefin/polystyrene blends and commingled plastic waste. Efficiency of this system can be further improved by incorporation of N,N´-disubstituted phenylenediamine stabilizer.
Recycling of soft polyurethane foams used in automobile industry
Beneš, Hynek ; Rösner, J. ; Horák, Zdeněk ; Kotek, Jiří ; Kovářová, Jana
Chemical recycling (glycolysis) of flexible PUR foams has been described. It was proved that obtained recycled polyols are suitable for preparation of rigid PUR foams and also for synthesis of compact PUR materials.
Impact of polymer recycling on environment
Horák, Zdeněk ; Beneš, Hynek ; Starý, Zdeněk ; Kruliš, Zdeněk
Negative impact of recycling technologies on living environment has been analyzed and concept of life cycle assessment (LCA - Life Cycle Assessment) has been shown as an efficient tool for selection of suitable recycling technology process. Several examples have proved usability of the mentioned approach.
