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 ...

Information on the flows of specific polymers through anthroposphere forms basis any assessment environmental implications plastic. This work presents a dynamic probabilistic material flow analysis seven commodity thermoplastics: low-density polyethylene (LDPE), high-density (HDPE), polypropylene (PP), polystyrene (PS), expanded (EPS), polyvinylchloride (PVC), and terephthalate (PET). The exami...

The global demand for plastic is increasing year by due to its indispensable uses and excellent properties. Plastic wastes persist many years their slow deterioration cause severe environmental problems. Therefore, there a growing focus worldwide on waste disposal methods overcome adverse impacts. As plastics are petroleum-based materials, the pyrolysis of fuel oil, gases, char, has more concer...

nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...

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...

The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view but it represents a goal that has yet to be achieved by the recycling industry. The W2Plastics project aims at a fundamental change of the present status of plastics recycling by creating a breakthrough technology for the recycling of polyolefin’s from complex wastes, i.e...
