This study evaluated the incidence of concentrated natural fibre, as well as the effects of adding a crosslinking agent on the torque when those components are mixed with low density polyethylene (LDPE). The natural fibre has a particle size of between 0.8-1.2mm and a moisture content of 0.17%. An internal mixer was used to measure the torque required to mix the polymer with the fibre. The effe...

This research work developed and evaluated the mechanical properties of coconut fibre reinforced low density polyethylene (LPDE) composite material. The effect loading on properties: tensile, flexural, impact material have been investigated. Also carried out was water absorptivity Sample categories were prepared by varying contents weight at 0%, 10%, 20%, 30%. aim is to reduce excessive waste d...

To understand the correlation between plastic structure and products, possible reaction mechanisms, pyrolysis–catalysis of different types waste plastics was investigated in presence an Fe/Al2O3 catalyst. Polypropylene (PP), high-density polyethylene (HDPE), low-density (LDPE), high-impact polystyrene (HIPS), general-purpose (GPPS) were used as feedstock. The results showed that PP, HDPE, LDPE ...

Atmospheric pressure discharge plasma has been studied and applied to environmental purification in recent years. We have been trying to purify diesel exhaust gas and we have verified that the combination of discharge plasma and honeycomb catalyst is quite effective for the exhaust treatment. However, complicated setup of high voltage power supplies and electrodes is required to generate stable...

In the present study, 7% silver-low-density thin polyethylene films were successfully prepared through the melt mixing method. These films were applied to reduce the harmful antibacterial properties of Huso huso fillets at refrigeration temperatures, thus extending their shelf life. The total viable bacteria count for H. huso fillets wrapped in a 7% Ag/LDPE nanocomposite was 3.04±2.43 (log CFU/...

Bio-based and biodegradable plastics promise considerable reductions in our dependency on fossil fuels the environmental impacts of plastic waste. This study quantifies economic consequences diverting municipal food waste wastewater sewage sludge from traditional management to biorefinery-based production polyhydroxyalkanoates (PHA) five geographical regions. The results show that PHA can outpe...

Abstract. The research presented in the article shows possibility of using some polymer materials composition asphalt concrete. analysis scientific works field concrete design efficiency plastic waste to obtain with specified physical, mechanical and operational properties. This technology allows not only reduce amount accumulated waste, but also improve condition highways by increasing strengt...

In this study, two strains of Aspergillus sp. and Lysinibacillus sp. with remarkable abilities to degrade low-density polyethylene (LDPE) were isolated from landfill soils in Tehran using enrichment culture and screening procedures. The biodegradation process was performed for 126 days in soil using UV- and non-UV-irradiated pure LDPE films without pro-oxidant additives in the presence and abse...

Polyolefins are of vast economic importance, which is reflected by an annual production of more than 70 million tons of polyethylene and polypropylene. While the major portion of these materials is produced with Zieglerand chromium-based catalysts, the older free-radical process that affords low-density polyethylene (LDPE) has maintained its significance.[1] Despite the necessity of working at ...
