Biodegradable films are a valuable and sustainable alternative to plastic for mulching soils since they avoid the environmental economic problems related removal disposal. Nevertheless, fast degradation of such materials could make them unsuitable mid- long-term use. In field experiment, agronomic performance biodegradable film (MB) was compared that conventional low-density polyethylene (LDPE)...
Increase of plastics accumulation in the environment cause ecological threats and has been one serious issue worldwide. In current study, two bacterial isolated strains Bacillus safensis amyloliquefaciens were used for their plastic degradation capabilities. The biodegradation low density polyethylene thermoplastic was assessed by weight reduction, Scanning electron microscopy (SEM) analysis cu...
The impact of a small amount polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (SEBS) on the thermomechanical and electrical properties blends comprising low-density polyethylene (LDPE) isotactic polypropylene (PP) is investigated. SEBS found to assemble at PP:LDPE interface as well within isolated PP domains. addition 10 wt% significantly increases storage modulus between melting temperat...
Proximate analysis, expressible water(EP), water holding capacity (WHC), pH value, total acidity, free fatty acids (FFA), thiobarbituric acid values (TBA), and microbiological examination were determined in order to evaluate the effect of packaging materials and treatments in addition to spice extracts on the shelf life of buffalo meat product stored for nine months under frozen condition. The ...
Abstract UF-SiAPP was prepared by modifying ammonium polyphosphate with the urea formaldehyde resin (UF), tetraethylorthosilicate (TEOS), and vinyltriethoxysilane (A-151). Moreover, a new intumescent flame retardant (IFR) used for low density polyethylene (LDPE) obtained mixing tris(2-hydroxyethyl) isocynurate (THEIC). The structure, morphology, mechanical properties of retardants LDPE composit...
The use of recycled raw materials and renewable sources are necessary for economical, social, environmental technological development. In this context, work aims to study the influence two lignin types, one derived from pine (Lig I) other eucalyptus, II) on polymer composites properties low density polyethylene (r-LDPE-Al) Pinus Elliotti wood flour (WF), in proportion 70% 30% matrix/reinforceme...
Plastics usage is rising daily because of increased population, modernization, and industrialization, which produces a lot plastic garbage. Due to their various chemical structures, long chain polymeric compositions, thermal/decomposition behavior, it challenging recycle these wastes into hydrocarbon fuels. In the current work, domestic waste was pyrolyzed at 473 973 K in fixed bed reactor comp...
