used pet bottles disposal is an unsolved environmental problem, and there are many efforts for finding an applicable solution for it. many researches have showed that the degradation rate of the polymers increase with the smaller size of fibers. this work was carried out to convert used pet bottles into nanofibers by melt-electrospinning method. uncolored, washed and chipped pet bottles and the...

Problem: The demand of beverages in PET bottles is constantly increasing. In this context, environmental, technological and regulatory aspects set a stronger focus on recycling. Generally, the reuse of recycled material from post-consumer PET bottles in bottle-to-bottle applications is seen as least environmentally harmful. However, closedloop systems are not widely implemented in Europe. Previ...

in iran, the majority of vegetable oil producers , use pet for packaging their products . due to high solubility of pet oligomers in the oils , and shelf life of liquid oils , it is expected that some compounds migrate into the oil . this study was carried out to determine the amount of migration of terephtalates from pet bottles into sunflower oil and the effect of temperature and storage time...

interaction of menthol with polyethylene terephthalate bottles during storage time was tested at three different temperatures. menthol is a mint flavor agent added to yogurt drinks in iran and is considered as a factor affecting consumer acceptance. absorption of menthol to packaging material could cause a loss of quality in the final product due to diminished flavor intensity. tests were done ...

With the European Green Deal, importance of recycled products and materials has increased. Specifically, for PET bottles, a high content material (rPET) is demanded by industry consumers. This study was carried out in lab environment replicating real-life industrial processes, to investigate possible impacts on rPET quality over eleven recycling loops, aiming use amounts repetitively. A cycle i...

Due to the rapid industrialization taking place globally, the problems generated are acute shortage of construction material and increasing in productivity of wastes. The production and consumption of plastic and the rate at which solid plastic waste (SPW) are created have increased considerably. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. Th...

Eco -friendly architectural principles are being incorporated into more buildings every day in the world but they are still out of reach of many people due to lack of knowledge and awareness. Nevertheless, many traditional societies learned to build collaborating with nature, basing their buildings on an intuitive knowledge of the environment and climate, constructing buildings at a very low co...

Due to its chemical inertness and physical properties PET is particularly suitable for food packaging applications, especially for drinking water. More bottled water is consumed than other bottled beverages. This article is a survey and toxicological investigation of chemical compounds, which are able to diffuse from PET bottles to water. The exact detailed chemical composition of plastic mater...

Poly(ethylene terephthalate) (PET) bottles are widely used for beverages. Knowledge about the migration of organic compounds from the PET bottle wall into contact media is of interest especially when post-consumer recyclates are introduced into new PET bottles. Using migration theory, the migration of a compound can be calculated if the concentration in the bottle wall is known. On the other ha...
