3D printers have grown in popularity recent years because of their ability to print objects quickly and easily. The material used on a 3d printer is called the filament. Using recycled materials produce filament gaining printing industry. One that can be make waste bottles Polyethylene Terephthalate (PET) type. This research was conducted see effect speed object dimensional stability. In this s...

Using the Life Cycle Assessment methodology, this study assesses environmental sustainability of two packaging alternatives for extra virgin olive oil: glass bottle and PET produced with 100% recycled granulate. Six scenarios were compared varying on type system distribution phase (in terms country logistics). The life cycle impacts estimated ReCiPe 2018 H evaluation method, using both midpoint...

Abstract The vast amount of not-recycled polyethylene terephthalate (PET) bottle waste is a serious threat to the environment. In order utilize waste, PET ultrafiltration membranes were prepared using as raw material by phase inversion technique. Low molecular weight glycol (PEG 400) was used additive for membranes. resin also membrane compare properties from and those resin. that showed simila...

In order to reduce carbon dioxide (CO₂) emissions and produce an eco-friendly construction material, a type of concrete that uses a minimal amount of cement, yet still retains equivalent properties to ordinary cement concrete, has been developed and studied all over the world. Hwangtoh, a type of red clay broadly deposited around the world, has traditionally been considered an eco-friendly cons...

Until now, there have been various studies concerning bottle-fed and breast-fed children. Prevalence of allergic manifestations like eczema and asthma among bottle-fed children is much higher than healthy controls. In this study, we found that respiratory infection for breast-fed children was 3.1%, whereas in bottle-fed children it was 25.1%for gut disorders, 9.2% in breast-fed vs.13.1 % f...
