The high need for polymeric materials and the availability of agro-industrial wastes, such as rice production chain, demand development technologies to obtain composites based on these waste materials. Therefore, this work aims develop using low density polyethylene (LDPE) a polymer matrix husk or ash, prepared by micronization in whirlwind mill, reinforcing fillers. processing was carried out ...

Visible-light-absorbing graphitic carbon nitride–TiO2 nanorod nanomaterials (g-C3N4@TiO2NR) were successfully immobilized using a one-step UVA-induced photocatalytic procedure on commercially obtained flexible low-density polyethylene (LDPE) films. Self-cleaning properties evaluated in solid–liquid and solid–gas phases malachite green as model molecule under UV-A visible light irradiation. For ...

In the UK waste management systems biodegradable and compostable packaging are not automatically detected separated. As a result, their fate is generally landfill or incineration, neither of which an environmentally good outcome. Thus, effective sorting technologies for plastics needed to help improve composting rates these materials reduce contamination recycling streams. Hyperspectral imaging...

This article focuses on increasing the shelf life of both pasteurized (Pa) and traditional (Tr) butters wrapped in Ag-Low Density Polyethylene (LDPE) film concentration 2.5%, 7.5%, 12.5%, 17.5% at refrigerated temperature up to one month. Silver nanoparticles were synthesized (20.63 nm) through chemical reduction followed by melt mixing method produce Ag-LDPE films. A mixed model-ANOVA Repeated...

Microplastic particles (MPs) are widely distributed pollutants in the environment. While a growing number of studies have shown that MPs toxic to plant and animal life, systemic efforts reduce their presence been scarce. Low-density polyethylene (LDPE) polystyrene (PS) one most common among all plastic-forming MPs. In this study, pure bacterial strains, Bacillus licheniformis Lysinibacillus &lt...

Nowadays, nanoscale innovations in the forms of pathogen detection, active packaging, antimicrobial packaging and barrier formation are poised to elevate food packaging to new heights. Antimicrobial nanocomposite LDPE films containing ZnO nanoparticles at different concentrations (e.g. 1%, 3%, 5%  and 3%  nano-ZnO pulse 10% polyethylene grafted maleic anhydride (PE-g-MA), w/w pure LDPE), were p...

Multi-objective optimization of an industrial low-density polyethylene (LDPE) tubular reactor is carried out at design stage with the following objectives: maximization of monomer conversion and minimization of normalized side products (methyl, vinyl, and vinylidene groups), both at the reactor end, with end-point constraint on number-average molecular weight (Mn,f) in the product. An inequalit...
