Abstract This study presents a new approach for the recycling of bilayered PET waste in an efficient, continuous process with depolymerization degree >97%. The complex was converted by chemolysis into its monomers ethylene glycol (EG) and corresponding salt terephthalic acid (TA) twin-screw extruder (TSE). Via this method, starting materials production were recovered, highly contaminated com...

The massive amount of plastic waste in our natural environment is a global concern. In this study, recycling to partially replace sand concrete investigated. performance Resin8, unique combination all types plastics and Polyethylene Terephthalate (PET) concrete, has also been Replacement contents 5%, 10%, 15% for by volume were performed. mixes incorporating recycled tested against reference mi...

Abstract Biocatalytic degradation is an emerging strategy aiming for energy-efficient recycling of poly(ethylene terephthalate) (PET), the most commonly used thermoplastic polyester. Besides material composition and physico-chemical parameters, kinetics co-determined by evolving nanotopography. In this study, 3-dimensional development surface characteristics amorphous PET film, reacted with a h...

This was a cross-sectional study to explore the factors influencing practices about household sharp waste management among type 2 diabetics in Delhi, India. The study used selfadministered questionnaires to find socio-demographic characteristics, diabetes management characteristics, and knowledge, attitude and practices (KAP) towards household sharp waste management. While there is a large amou...

The waste problem in Indonesia is an unfinished problem. growing population increases the amount of originating from human activities, both organic and inorganic waste. Inorganic such as plastic difficult to decompose naturally, so research needed on use make environmentally friendly paving blocks. aim this know compressive strength percentage water absorption value. Using experimental data col...

There has been a considerable imbalance between the availability of conventional building materials and their demand in recent past. On other hand, plastic waste is abundantly available disposal Polyethylene Terephthalate Plastics (PET) big challenge, as repeated recycling PET bottles poses potential danger being transformed only small proportion are recycled. In this work an attempt made to ac...

The co-pyrolysis of various biomasses mixed with two types plastic waste was investigated in this study. Mixture M1 consisted 30% m/m styrene–butadiene rubber (SBR), 40% polyethylene terephthalate (PET), and polypropylene (PP). M2 PET, PP, acrylonitrile–butadiene–styrene copolymer (ABS). SBR, ABS, PP used study were from the automotive industry, while PET originated scrap bottles. Co-pyrolysis ...

This paper investigates the effects of properties fresh concrete incorporating shredded Polyethylene Terephthalate (PET) bottles and Manufactured Sand (M-sand) together as fine aggregates replacement in mixtures. The investigation to determine correlation were mainly experimental based experiments involved Slump Test, VeBe Test Compaction Factor Test. There two different batches prepared, which...

Abstract Physical recycling of plastics is among the most important approaches circular economy. The efficiency influenced by many factors including number cycles, composition plastics, chemical modifications, additives and others. Currently, however, there are no methods enabling to distinguish quality for recycling. In this work, we address issue suggest a new method based on correlation sole...

The enzymatic degradation of polyethylene terephthalate (PET) occurs at mild reaction conditions and may find applications in environmentally friendly plastic waste recycling processes. The hydrolytic activity of the homologous polyester hydrolases LC cutinase (LCC) from a compost metagenome and TfCut2 from Thermobifida fusca KW3 against PET films was strongly influenced by the reaction medium ...
