subgrade soil stabilization is one of the primary and major processes in the construction of any highway; also environmental authorities are concerned about the growing amount of polyethylene (pet) bottles produced by household sectors. this research in order to study effect of adding recycled polyester fiber on soil engineering properties, especially shear strength and california bearing ratio...

Bioremediation. The discovery of MG8, an efficient polyethylene terephthalate (PET) hydrolase enzyme from the human saliva metagenome, is reported by Worawan Bhanthumnavin, Chayasith Uttamapinant et al. in their Research Article (e202203061). Aside its plastic degradation capability, MG8 was further engineered via genetic code expansion into a covalent binder PET and can be used to attach prote...

The research aims to utilize polyethylene (PET), polypropylene (PP) and polystyrene (PS) plastic waste into liquid fuel by the pyrolysis process, currently, especially in Surabaya, a lot of waste, 13% - 14% is plastic. results sample from this study are distinguish temperature steam entering condenser also water condenser. And what will later be tested that oil close type gasoline or diesel. fo...

There are few studies on microplastic (MP) contamination in Colombia, and little is known about its impacts continental aquatic ecosystems. This study evaluated, for the first time, identification, abundance, distribution of MP particles surface water Luruaco Lake, low basin Magdalena River, included national programs marine sciences hydrobiological resources. Six stations four samplings were e...

Metals in recycled polyethylene terephthalate (PET) were analyzed by ICP-MS following microwave digestion with nitric acid. Physically and superclean-like recycled PET contained both Ge and Sb, and sometimes contained Co, P or Si. In contrast, the chemically recycled PET contained only Ge or Sb, and some samples contained Co. The recycled PETs did not contain Pb or Cd. Ge and Sb were catalysts ...

BACKGROUND Recent reports suggest that endocrine disruptors may leach into the contents of bottles made from polyethylene terephthalate (PET). PET is the main ingredient in most clear plastic containers used for beverages and condiments worldwide and has previously been generally assumed not to be a source of endocrine disruptors. OBJECTIVE I begin by considering evidence that bottles made fr...

In situ growth of cyclodextrin-based metal-organic frameworks (CD-MOFs) is investigated for the effective fabrication MOF composites through vapor diffusion method combined with O2 plasma treatment. The rate γ-CD-MOFs on poly(ethylene terephthalate) fibers (CD-MOFs–PET) determined 136 h, and CD-MOFs-PET 24 h time shows highest surface area without crystal deformation. specific 142.88 m2 g−1, wh...

Industrial-scale upcycling of waste polyethylene terephthalate (PET) plastic into porous carbon globally for CO 2 capture was verified as a multifunctional alternative to conventional absorption and management technologies.

In the rapidly developing modern society, many raw materials, such as crushed limestone and river sand, which are limited, are consumed by the concrete industry. Naturally, the usage of waste materials in concrete have become an interesting research area in recent years, which is used to reduce the negative influence of concrete on the environment. Hence, this paper presents the development of ...
