Turn Plastic Back to Oil?

The BLEST company from Japan introduced a machine back in 2007 that they claim can revert waste plastic back to its oil form, without the use of flames or excessive gas emissions. The claim was revisited recently by Our World 2.0. Check out the excerpt below.

Though Japan has much improved its “effective utilization” rate over the years to 72% in 2006, that leaves 28% of plastic to be buried in landfills or burned. According to Plastic Waste Management Institute data, “effective utilization” includes not just the 20% that is actually recycled, but also 52% that is being incinerated for “energy recovery” purposes, i.e., generating heat or electric power.

“If we burn the plastic, we generate toxins and a large amount of CO2. If we convert it into oil, we save CO2 and at the same time increase people’s awareness about the value of plastic garbage,” says Akinori Ito, CEO of Blest.

Blest’s conversion technology is very safe because it uses a temperature controlling electric heater rather than flame. The machines are able to process polyethylene, polystyrene and polypropylene (numbers 2-4) but not PET bottles (number 1). The result is a crude gas that can fuel things like generators or stoves and, when refined, can even be pumped into a car, a boat or motorbike. One kilogram of plastic produces almost one liter of oil. To convert that amount takes about 1 kilowatt of electricity, which is approximately ¥20 or 20 cents’ worth.
