Gasoline from plastic scrap

A liter of gasoline can be obtained from a kilogram of old plastic sachets by applying a technology being developed by the specialists of the Mendeleyev Chemical Engineering University in Russia . The technology focuses on obtaining gasoline mainly from man-caused carbonic wastes – such as polyethylene, polypropylene, polystyrene and polyethylene terephthalate wastes. It is only known that these are grinded wastes of a single production. The technology suggested by V.F. Shvets and his colleagues is based on catalytic thermal treatment of polymeric materials. Its basic stages are as follows: First, the wastes should be grinded (it is not necessary to wash them) and melted down. Then they should be mixed with the catalyst powder and exposed to thermal destruction, (kept for some time in the reactor at a definite temperature and pressure)

Innovation in plastics will provide opportunity in fuel cell application

Unlike a battery cell, fuel cell operates indefinitely and yields only water. A fuel cell is an electrochemical device that generates electricity and heat and is expected to replace lithium batteries. The most promising technology looks to be that of proton exchange membrane which is suitable for 1-50 KW output. The cell uses polymer membrane and conductive plate that divides, reunite proton and electron generating electricity. Many cells would be required to generate sufficient electricity since each cell produces only small amount of current.

Flexible packaging gains market share as it replaces rigid packaging

Plastic flexible packaging is gaining market share globally, including in North America , as per a report by Freedonia. Gains in packaging will benefit from changes in food consumption patterns and trends such as portion control, which are altering the way snack food is packaged. Flexible packaging will benefit from the trend toward individually wrapped products, of which pouches are expected to experience the fastest growth through 2010.

HDPE pipes – sustainable solution for water crisis in India

The Indian Subcontinent and Water Crisis India is the 7 th largest country by geographical area and the second most populous country in the world. Of India's 1.1 billion people, almost 70 % of the Indians reside in rural areas, though in recent decades migration to larger cities has led to the exponential rise in the urban population.

Legilative regulations provide an opportunity for growth of bio plastics

Bio plastics, being a new class of polymers having influence on the waste disposal problems of polymers, have to depend upon international regulations and standards. These have a tremendous impact on the growth of bio plastics. The use of bio plastics in packaging depends upon the regulations & standards and their acceptance all over the World.

Eliminating black spots in extruded film/sheet with careful processing and good quality polymer

Processors occasionally find black spots in extruded products such as films and sheets. Thin film creates very conspicuous black spots that are obviously not only unacceptable, but can create holes in the product when the film is subsequently oriented. The two basic sources for black spots either originate in the polymer raw material or gets introduced during processing. The polymer can also contain formulation defects that char instead of melting, becoming a dark speck surrounded by a gel.
