$10,000-Gizmo Lets You Turn Plastic Bags Back Into Petroleum

By Patrick Morgan | February 17, 2011 5:43 pm

You could be spared the guilt of forgetting your eco-friendly cloth shopping bag on the trip to the grocery: A Japanese inventor has created the first home recycling system that can convert all those extra plastic bags back into oil.

His name is Akinori Ito, and his invention is now for sale through Blest Corporation. According to the website, one model–the Desk-top Waste Plastic Oiling System–weighs a mere 110 pounds. But the best part is that this non-polluting conversion process is also highly efficient: two pounds of plastic can be converted into one quart of oil using a mere kilowatt-hour of energy (a cost of roughly 20 cents).

It works by capturing the vapors released by heated plastic, and then funneling them through a network of pipes and water chambers, which gradually cool the vapors until they coalesce back into crude oil–where the plastics originally came from.

Everybody Panic! Reusable Shopping Bags Harbor Bacteria

By Eliza Strickland | June 25, 2010 12:04 pm

reusable-bagSo at some point you decided to do the right thing for the environment, and plonked down a couple of dollars for a reusable grocery bag. Bet you felt pretty good about yourself, huh? Well, some researchers have now come along to rain on your virtue parade. According to a new report (pdf), that bag is probably crawling with bacteria.

The researchers tested 84 bags, and found that all but one harbored bacterial colonies, and half contained coliform bacteria that suggest raw meat or uncooked food contamination. They also surveyed consumers about their use of these bags, and found that most people don’t keep separate bags for meat, and that they’re likely to tote clothes and all sorts of other things in these bags when they’re not grocery store-bound. Both these practices could allow for bacterial colonization.

But before you burn your reusable bags in a cleansing fire, consider this: The researchers also determined that either chucking a bag in the washing machine or rinsing it by hand reduced the bacterial counts to almost zero.

And The Washington Post dispassionately chimes in on another very relevant note:

The study was funded by the American Chemistry Council amid debate over a California bill that would ban single-use plastic bags. The council is opposed to that measure.
