The study of the presence bisphenol analogs in environment has been very relevant recent years because their toxic potential discovered, and since they are not regulated like A, use industry excessive. This identifies quantifies for first time A four uncommon waste from polypropylene (PP) polyethylene terephthalate (PET) production processes that may originate degradation some compounds used du...

Plastic waste disposal is a significant environmental concern due to its low degradability and management practices, especially in developing countries. recycling considered the most effective method, which minimizes impacts. This paper discusses use of poly(ethylene terephthalate) (PET), high-density polyethylene (HDPE), polypropylene (PP) plastic as aggregates concrete industry by incorporati...

This study aimed to assess the amount of plate waste and how plate waste was disposed by early adolescent girls using a mobile food record (mFR). Participants were girls nine to thirteen years residing in O'ahu, Hawai'i (n = 93). Foods selected and leftover were estimated using a three day mFR. Each leftover food was then classified as thrown into the trash, fed to a pet, eaten later, or other ...

objective(s): the ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. the aim of this study was to evaluate the uptake of 18ffluorothymidine (flt) pet in renal cell carcinoma (rcc), and to compare this to 18f-fluorodeoxyglucose (fdg), and to an immunohistochemical measure of cellular proliferatio...

The depolymerization of polymers by enzymes is of great interest for biodegradable plastics, a group of materials which has been developed as an answer to increasing problems in plastics waste management. Polyesters play the dominant role in biodegradable polymers and recently a model of polyester degradation by hydrolyses (lipases) has been published. The chain mobility of the polymer chains p...

This study aims to investigate the effect and possibility of using waste plastic as a sustainable cost-effective polymer modify bitumen binders. Different types have been used in this modification, including polyethylene terephthalate (PET), high-density (HDPE), low-density (LDPE). The modification targets physical characteristics, rheological properties, binders’ resistance ageing. Both long- ...

Abstract: One of the most abundant and negative impacts on environment is plastic waste. PET (Polyethylene Terephthalate) bottle waste largest waste, has not been processed optimally. The purpose this research was to examine manufacture briquettes from mixed with natural materials, such as coconut shells wood sawdust starch adhesive. This uses an experimental method that begins carbonization pr...

Water shortage is an immediate and serious threat to our world population. Inexpensive and scalable methods to clean freshwater and wastewater are in high demand. Nanofiber filtration membranes represent a next generation nonwoven filter media due to their unique properties. Polyethlyene terephthalate (PET) is often used in the packaging of water and other commonly used materials, leading to a ...

The global aquatic pet trade encompasses a wide diversity of freshwater and marine organisms. While relying on a continual supply of healthy, vibrant aquatic animals, few sustainability initiatives exist within this sector. Public aquariums overlap this industry by acquiring many of the same species through the same sources. End users are also similar, as many aquarium visitors are home aquaris...

Biomass use and recycling are among the few options to reduce greenhouse gas (GHG) emissions of growing plastics sector. The bio-based plastic polyethylene furanoate (PEF) is a promising alternative terephthalate (PET), in particular for small bottle applications. For first time, we assessed life cycle global warming potential (GWP) 250 mL PET PEF bottles over multiple mechanical (MR) chemical ...
