Plastics wastes from a municipal solid waste (MSW) plant have a high-energy content and are suitable for fuel generation. Thermal cracking is one of the possible ways to obtain petrochemical feedstock from polymer wastes. Municipal waste plastic of LDPE conversion to kerosene grade fuel experiments were carried out under atmospheric conditions at temperatures between 150 ̊C and 420 ̊C. Low densit...

Polyethylene (PE) is one of the most widely used polymers in many industrial applications. Biomedical uses seem to be attractive, with increasing interest. However, PE it prone to infections and its additional surface treatment is indispensable. An increase in resistance to infections can be achieved by treating PE surfaces with substances containing antibacterial groups such as triclosan (5-Ch...

Nine urban intertidal regions in Burrard Inlet, Vancouver, British Columbia, Canada, were sampled for plastic debris. Debris included macro and micro plastics and originated from a wide diversity of uses ranging from personal hygiene to solar cells. Debris was characterized for its polymer through standard physiochemical characteristics, then subject to a weak acid extraction to remove the meta...

--This study attempts to understand the effect of different UV irradiation methods on the intercalation of LDPE/MMT nanocomposites, and its molecular behavior at certain isothermal crystallization temperature. Three different methods of UV exposure were employed using single composition of LDPE/MMT nanocomposites. All samples were annealed for 5 hours at a crystallization temperature of 100oC. ...

In this study, pyrolysis of low-density polyethylene (LDPE) and LDPE with aluminum (C/LDPE) wastes was carried out different heating rates (5, 10, 20 °C/min) at temperatures (400, 600, 800 °C). Product yields C/LDPE were compared, optimum liquid products analyzed to utilize as commercial waxes for future use. The properties pyrolyzed investigated proximate, elemental analysis, TGA. as-produced ...

The fracture toughness of a polymer-metal laminate composite is obtained by mechanical testing of a specimen containing a pre-crack. The laminate is a material used for packaging. It consists of a thin aluminium foil and a polymer coating. A centre cracked panel test geometry is used. Each of the layers forming the laminate is also tested separately. The result is compared with the measured fra...

We had immobilized cytochrome P450 (CYP) 1A2 and CYP reductase (CPR) onto a self-assembled phospholipid layer containing stearic acid (LDPE-StA-PC-SA) to confirm the functional interaction between CPR. The formation of resorufin from 7-ethoxy was observed by use film immobilizing CPR LDPE-StA-PC-SA. It clarified that fluidity LDPE-StA-PC-SA very important. actual activity did not depend on dens...

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...
