El Cajon, California (PressExposure) August 21, 2011 -- The machine produced in various sizes, for both industrial and home uses, can easily transform a kilogram of plastic waste into a liter of oil, using about 1 kWh of electricity but without emitting CO2 in the process. The machine uses a temperature controlling electric heater instead of flames, processing anything from polyethylene or polystyrene to polypropylene (numbers 2-4). 1 kg of plastic produces one liter of oil, which costs $1.50. This process uses only about 1 kWh of electricity, which costs less than 20 cents!
As a child, Akinori Ito of the Blest Corporation, enjoyed playing in nature and like most children, didn't give much thought to the environment. But since growing up and having children of his own, he noticed the places where he used to play as a child had disappeared and decided to do something about it.
In 2000, there was much discussion about global warming. Also, in Japan there is very little space for garbage. Elsewhere in the world there are few places to dispose of garbage and the effects of trash can be very bad.
So Akinori thought that by using Japanese technology they should be able to convert the plastic garbage back into the oil it is produced from. It is made from oil so it should not be very difficult to covert it back, he thought, and that is how it started.
A good point of the small machine is that the plastic does not need to be broken down. You can insert it into the machines chamber as is. Here is how the plastic is converted back to oil; You turn on the machine and the temperature begins to rise. The plastics will begin to melt, and become a liquid. After the liquid begins to boil, gasses pass through a tube and enter a gas-trapping unit filled with tap water. The water cools the gas and turns the gas into oil.
The oil is OK to burn as is but can be further refined to produce gasoline, diesel and kerosene. If you further separate the oil, then it can be used for a car, motorbike, generator, boiler or stove. It can be used the same as regular oil.
Burning 1kg of plastic produces 3kg of CO2. Using electricity and heat, the plastic can be returned to oil and reduce about 80% of CO2 emissions.
