Carbon Life-Cycle Assessments: Friend or Foe?

  • Posted on July 30, 2011 at 10:58 pm

Naomi Soderstrom, accounting professor at the Leeds School of Business, discusses the value and limitations of a life-cycle assessment, a popular tool that measures the environmental impact of an object from production through consumption. She explains how their accuracy depends on the scope and assumptions of the assessment. For example, when measuring a paper bag, do you assume the paper was harvested from a managed or wild forest? For a plastic bag, do you add the environmental impact of oil extraction embodied in the plastic?

Waste Plastic to Carbon nanotubes for Lithium-ion batteries : An innovation by Dr. Pol

ABC7 TV NEWS, January 15, 2010 (WLS) Hosea Sanders — Plastic bags from the grocery store could soon help power your cell phone. A suburban company is developing new technology that’s giving new life for the bags that usually ended up in a landfill. Plastic bags can take hundreds of years to decompose in a landfill and they are among the most challenging items for recyclers to manage. But new technology could turn those inexpensive bags into a commodity that’s highly valuable — and green. “Those are the carbon nanotubes which are working for this battery,” said Vilas Ganpat Pol, Argonne National Laboratory. This product that could change the price of a number of your favorite gadgets. “My supervisor asked me can we do something with the plastics?” said Pol. The chemist at Argonne National Laboratory. For the last couple of years, he’s been trying to find a good use for those menacing plastic bags. “They are everywhere. They take hundreds of years to decompose,” said Pol. After much trial and error, the 35-year-old thinks he finally hit the jackpot. Pol cuts up a plastic bag, stuffs it in a reactor, adds a cobalt metal catalyst and then heats it all up to 700-degrees Celsius. After a three hour cool down, he gets carbon nanotubes. It looks like a simple black powder, but it may as well be gold. The substance can be used in lithium-ion batteries — like the ones in your cell phone. It helps make them rechargeable. Pol’s findings are significant because making these …

moldless vacuum bagging carbon fiber bicycle frame

  • Posted on July 27, 2011 at 11:30 am

Using fillament wound carbon fiber tubing and prepreg carbon fiber plates as reinforcement gussets I was able to make a carbon fiber drivetrain chassis for a streamlined recumbent bicycle. We tacked the mitered tubes and gussets together with super glue on a granite surface plate to ensure perfect allignment and then wrapped them with woven carbon fiber tape and fabric that had been wet out with Loctite/Hysol E-120hp aerospace grade epoxy. Then using a welded aluminum frame with traditional bagging film, breather, peel ply on both sides we were able to achieve 30 inches of vacuum and held it for 12 hours. the next video in the series shows the part after curing.
