The influence of different additives: high density polyethylene (HDPE), low density polyethylene (LDPE) and TiO2 nanoparticles on the polyethylene terephthalate (PET)–rubber nanocomposite interface was investigated. The composites obtained by compression moulding from tire rubber and PET bottles’ waste were partially heterogeneous and partially compatible, as confirmed by the FTIRmeasurements. ...

The exponential increase of plastic production produces 100 million tonnes of waste plastics annually which could be converted into hydrocarbon fuels in a thermal cracking process called pyrolysis. In this research work, a direct current (DC) thermal plasma circuit is designed and used for conversion of low density polyethylene (LDPE) into diesel oil in a laboratory scale pyrolysis reactor. The...

High-density polyethylene (HDPE) has a linear structure with very little or no branching and possesses a high degree of crystallinity, but it is difficult to process. Low-density polyethylene (LDPE) however has a chaotic structure with short and long branches and is easy to process. Blending of polyethylenes (PEs) is a common industrial practice. The principal reasons behind the blending of PEs...

Background: Pseudomonas sp. AKS2 can efficiently degrade low-density polyethylene (LDPE). It has been shown that this degradation of LDPE by AKS2 is correlated to its ability to form biofilm on the polymer surface. However, the underlying mechanism of this biofilm-mediated degradation remains unclear. Since bioremediation potential of an organism is related to its adaptability in a given enviro...

There is a paramount demand on the enhancement of plastic package properties to reduce food loss and waste. With this awareness, ternary composite films based low density polyethylene (LDPE) reinforced with silver- (Ag/FS), copper- (Cu/FS) copper hydroxynitrate-fumed silica (CuHS/FS) micron-sized dual-side fillers, were produced via melt-blending compression molding techniques. The exhibited an...

We have fabricated three-layer films, comprising a varying content of ethylene–vinyl alcohol copolymer (EVOH) as the internal layer and blends of low-density polyethylene (LDPE) and low-density ethylene grafted with maleic anhydride (LDPE-g-MAH) as the external layers, by a coextrusion blown-film process. We chose to use blends to promote the adhesion between EVOH and LDPE and to reduce the num...

Simultaneous thermogravimetry-mass spectrometry studies of a pyrolytic decomposition of mixtures of different plastic wastes/coking coal were carried out. The investigation was performed at temperatures up to 1000oC in a helium atmosphere under dynamic conditions at a heating rate of 25 oC/min. Five thermoplastics, commonly found in municipal wastes: low density polyethylene (LDPE), high densit...

Hydrogen is largely produced via natural gas reforming or electrochemical water-splitting, leaving organic solid feedstocks under-utilized. Plasma technology powered by renewable electricity can lead to the sustainable upcycling of plastic waste and production green hydrogen. In this work, low-temperature atmospheric pressure plasma reactors based on transferred arc (transarc) gliding (glidarc)...

The global production and consumption of plastics have continued to increase. Plastics degrade slowly, causing persistent environmental pollution Developed waste plastic recycling methods are discussed in this report, with a focus on the dissolution/reprecipitation technique restore low-density polyethene (LDPE) wastes. Aspen HYSYS is used simulate LDPE. Turpentine/petroleum ether (TURP/PetE) c...

An innovative way to fix preformed nanocrystalline TiO(2) on low-density polyethylene film (LDPE-TiO(2)) is presented. The LDPE-TiO(2) film was able to mediate the complete photodiscoloration of Orange II using about seven times less catalyst than a TiO(2) suspension and proceeded with a photonic efficiency of approximately 0.02. The catalyst shows photostability over long operational periods d...
