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...

Marine debris (MDs) produces a wide variety of negative environmental, economic, safety, health and cultural impacts. Most marine litter has a very low decomposition rate (plastics), leading to a gradual accumulation in the coastal and marine environment. Characterization of the MDs has been done in terms of their pollutant content: PAHs, ClBzs, ClPhs, BrPhs, PCDD/Fs and PCBs. The results show ...

Poly(ethylene terephthalate) (PET) is a highly useful synthetic polyester plastic that widely used in daily life. However, the increase postconsumer PET as waste recalcitrant to biodegradation landfills and natural environment has raised worldwide concern. Currently, traditional recycling processes with thermomechanical or chemical methods also result deterioration of mechanical properties PET....

Multilayer plastic films provide a range of properties, which cannot be obtained from monolayer films but, at present, their recyclability is an open issue and should be improved. Research to date has shown the possibility of using whey protein as a layer material with the property of acting as an excellent barrier against oxygen and moisture, replacing petrochemical non-recyclable materials. T...

In nature, enzymes that deconstruct biological polymers, such as cellulose and chitin, often exhibit multi-domain architectures, comprising a catalytic domain non-catalytic binding module; the latter serves to increase enzyme concentration at substrate surface. This architecture has been shown improve hydrolysis of poly(ethylene terephthalate) (PET) using engineered cutinase enzymes. Here, we e...

Localism or regionalization has become a popular topic in urban design, but recent critics raise the question of whether the local or regional scale is most desirable for industrial ecosystems. As a way to explore the claim that localized metabolism is more sustainable, this study examines the costs and benefits of two differentially scaled strategies for the management of post-consumer polyeth...

The effect of high shear rate on the mechanical properties polyethylene (PE), poly(ethylene terephthalate) (PET), polystyrene (PS) and polypropylene (PP) waste blend was investigated. process carried out at a temperature 120°C using counter-rotating twin-screw extruder. A constant screw speed 250 rpm weight ratio PE/ PET/PS/PP components 1:1:1:1 were used. preliminary research showed that had n...

Human contact with cats, dogs, and other pets results in several million infections each year in the United States, ranging from self-limited skin conditions to life-threatening systemic illnesses. Toxoplasmosis is one of the most common pet-related parasitic infections. Although toxoplasmosis is usually asymptomatic or mild, it may cause serious congenital infection if a woman is exposed durin...

Fast fashion trends lead to significant quantities of textiles produced and discarded, its waste is incinerated or landfilled due a lack recycling technologies for mixed textiles. Recycling by hydrothermal liquefaction (HTL) novel approach produce bio-oil monomers, as no prior sorting color removal required. Herein, post-consumer polyester (polyethylene terephthalate (PET)) cotton garments were...

Abstract In recent times, efforts are channeled towards limiting the impact of waste plastic pollution on environment. This study examines beneficial utilization polyethylene terephthalate (PET) wastes, which is a non-biodegradable materials as partial substitute for sand in production non-load bearing hollow sandcrete blocks. The physical and mechanical properties such density compressive stre...
