Polyethylene terephthalate (PET) bottles are widely used as packaging material for natural mineral water. However, trace levels of acetaldehyde can migrate into natural mineral water during the shelf life and might influence the taste of the PET bottled water. 2-Aminobenzamide is widely used during PET bottle production as a scavenging agent for acetaldehyde. The aim of this study was the deter...
The United States generates the most plastic waste of any country and is a top contributor to global pollution. Multiple end-of-life strategies must be implemented minimize environmental impacts retain valuable material, but it challenging compare options that generate products with different lifetimes utilities. Herein, they present material flow model equipped consequential life cycle assessm...
The purpose of this study was to investigate the impact of temperature on the release of PET-bottle constituents into water and to assess the potential health hazard using in vitro bioassays with bacteria and human cell lines. Aldehydes, trace metals and other compounds found in plastic packaging were analysed in PET-bottled water stored at different temperatures: 40, 50, and 60°C. In this stud...
Polyethylene terephthalate (PET) is widely used in textile fiber, film, and bottles. Although PET bottle recycling has made great progress, other waste still not recycled. Gasification could be an option for or recovering energy chemicals from waste. However, single stream steam gasification fluidized bed seldom investigated. In this paper, individual experiments were then conducted a lab-scale...
Plastics play an essential role in modern society; however, the relentless growth of their production is threatening both human health and ecosystems. As a result, there are intensive efforts developing recycling technologies to repurpose waste plastics into building blocks for valuable materials. Here we show binuclear complex that can catalyse degradation poly(ethylene terephthalate) (PET)—th...
Studies on packaging accessibility are still incipient in Brazil. Many of these packagings can represent a challenge to users, whether due to non-informative labels, tricky tabs or seals, or even those that need strength to open. This paper brings a simple test to determine the necessary torque force to open PET bottles, and to predict the amount of users that could not open it. The findings su...
Stretch blow molding serves as the primary technique employed in production of polyethylene terephthalate (PET) bottles. Typically, a stretch machine consists various components, including preform infeed system, transfer heating bottle discharge etc. Of particular significance is temperature control within which significantly influences quality PET bottles, especially when confronted with envir...
One of the practical ways to overcome adverse environmental effects plastic bottle waste is implement bottles into concrete, one most widely used materials in construction industry. Plastic are mainly made polyethylene terephthalate (PET) and can be as a fiber reinforce concrete. In recent years, PET fiber-reinforced concrete (PFRC) has attracted researcher attention, several experimental studi...
Relatively recent citizen’s consciousness about plastic pollution forces industrial actors of packaging to re-invent their shaping processes and materials. Specifically, for bottle industry shaping, classical Polyethylene Terephthalate (PET) material is little by replaced recycled PET (rPET). The change in composition due recycling loops leads an inevitable adaptation the Injection Stretch Blow...
