Although recycling is considered the core of a circular economy for returning materials to the supply chain, its procedures are poorly understood. Waste recycling is considered a big source of energy saving and a promoter of CO2 recovery. Besides that, it generates jobs and changes markets worldwide. The Brasilian National Policy on Solid Waste (PNRS) recognizes Waste Pickers as the major socia...

We present a comprehensive model to computationally study molecular structure development in the recycling extrusion process of low-density polyethylene (LDPE) and provide initial results versus reported experiments as guidance. Molecular weight distribution (MWD) branching (BD) are modeled by applying combination population balance modeling, method moments pseudo distributions. Special cares h...

The quantity of polymer waste in our communities is increasing significantly. It therefore necessary to consider reuse or recycling avoid an increase the risk public health. This project aimed at using pulverized low-density polyethylene (LDPE) as a source reinforce and improve compressive strength, reduce water absorption geopolymer ceramics (GC). Clay:LDPE composition consisting 5%, 10%, 15% ...

A powerful simple biochar catalyst derived from nanocellulose was applied to the catalytic upcycling of waste plastics into H2 and liquid fuels for first time. For results model low-density polyethylene (LDPE) pyrolysis, C8-C16 aliphatics monocyclic aromatics were dominant constitutes product with yields ranging 22 68 wt%. At temperature 500 °C LDPE ratio surpassing 3, could be completely degra...

In this study, some mechanical properties of wood-plastic composite material produced from bamboo (Bambusoideae) were investigated. Wood-plastic materials by mixing Low Density Polyethylene (LDPE) and fibers at the rates 5% 10%. The wood-composite samples subjected to tensile strength bending tests results examined. showed that decreased 6% as ratio increased addition, increasing 10% average ea...

Among the various requirements that high voltage direct current (HVDC) insulation materials need to satisfy, sufficiently low electrical conductivity is one of most important. The leading commercial HVDC material currently an exceptionally clean cross-linked low-density polyethylene (XLPE). Previous studies have reported DC-conductivity (LDPE) can be markedly reduced either by including a fract...

Aiming at reducing the environmental impact of low density polyethylene (LDPE) when employed as mulching film, this study was focused on partial substitution material with proteins extracted from Hermetia illucens, also known black soldier fly (BSF). Insects were reared chicken manure and food leftovers in a circular economy perspective. To evaluate effects processing conditions amount BSF prop...

Abstract This study experimentally demonstrates the potential of co-chlorination as a green process alternative to conventional independent chlorination polyolefins, which involves use non-environment-friendly solvents like carbon tetrachloride (CCl 4 ). Low-density polyethylene (LDPE) was used representative polymer in this and co-chlorinated with paraffin. Apart from being reactant, paraffin ...

Post-consumer plastic waste contains blends of numerous types polyethylene (PE) and isotactic polypropylene (i-PP), whose recycling is challenging due to the complexity this stream. A comprehensive knowledge composition these recyclates essential understand structure-property relationship systems therefore upcycle them for high-value applications. To aim, we used Temperature Modulated DSC (TM-D...

Graphite lacquer was simply sprayed on glass and low-density polyethylene (LDPE) substrates to obtain large area films. Scanning Electron Microscopy (SEM) images, Raman spectra, X Ray Diffraction (XRD) spectra current-voltage characteristics show that at room temperature, the as-deposited films different have similar morphological, structural electrical properties. The morphological characteriz...
