The Future of 3D Printing and Healthcare

When it comes to 3D printing, the sky is the limit. As 3D printing technology continues to advance, applications can be as far reaching as  airplane  and  automobile parts  to medical devices and even anatomically correct, biocompatible models. Although 3D printing technology is developing at a rapid pace, the technology itself is not new. It emerged in  the 1980s  as a means of creating rapid prototypes. In recent years the applications for 3D printed models have evolved with the available hardware, software, and printable materials. Evolving technology, paired with the creative and innovative minds of scientists, engineers, and physicians, has been the launching pad for developments within 3D printing technology specific to healthcare. One way 3D printing technology is poised to create better patient outcomes is in creating an anatomically and  patient-specific models  to aid in surgery and medical procedures. With the capability to 3D print patient-specific models, more acc

PET Recycling on the Rise

petrecycling
Two reports indicate that the U.S. recycling volume of polyethylene terephthalate (PET) went up in 2010, and the country’s recycling rate rose for the seventh consecutive year.
The plastic recycling industry’s annual all-bottle recycling rate report was released by the American Chemistry Council and the Association of Postconsumer Plastic Recyclers (APR). It includes data on PET and high-density polyethylene bottles and containers, which is the second most recycled plastic. Total plastic bottle recycling rate was 28.8%, up from 27.8% in 2009, and total pounds of plastic bottles collected increased by 123 million pounds for 2010 over 2009, with increases for PET, high-density polyethylene (HDPE), and polypropylene bottle resins, according to the report.
The numbers on recycling of post-consumer PET containers were presented in a report from the National Association for PET Container Resources (NAPCOR), APR, and the PET Resin Association. Mike Verespej, Washington, D.C. correspondent for Plastics News, writes:
After staying flat for two years, the volume of PET bottles recycled in the United States increased by 113 million pounds in 2010, pushing the recycling rate close to 30 percent for the first time since 1996.
The 2010 rate of 29.1 percent is up from a low of 19.6 percent in 2003, and is only 2.6 percentage points lower than the 31.7 percent rate in 1996.
Expanded bottle-deposit programs and sales that recovered to 2008 levels are responsible for the boost. NAPCOR told Verespej that although the total volume of PET bottles recycled increased from 1.444 billion pounds in 2009 to 1.557 billion pounds in 2010, almost half of the increase can be credited to expanded bottle-deposit programs in Oregon, Connecticut, and New York.
And, according to the NAPCOR report, negative growth in PET bottles and jars sold in the U.S. ended in 2010 with a rebound more robust than anticipated, and all beverage categories posted positive growth. Specifically, juice, juice drinks, and ready-to-drink tea had double-digit increases.
“Recycling our used plastics is one of the easiest ways all of us can help support our economy and the environment,” said Steve Alexander, executive director of APR in a statement. “Companies across the U.S., many of them small businesses, rely on a steady stream of recycled plastics to make useful, innovative products, such as performance fleece, low-maintenance backyard decks, kitchen gadgets, new bottles, and even auto parts.”
But the recycling industry may need to change how it does business to go further. To keep up with current and projected demand for recycled PET material, NAPCOR calculates that the PET bottle recycling rate would need to be at least 48% by 2013, according to its report. “Up to this point,” the report stated:
[T]he primary concerns of this industry — collection, design for recycling principles, and the use of recycled content — have been addressed voluntarily and inconsistently. The question is whether that sort of approach can support the current infrastructure and allow for the growth that will be necessary to make this a sustainable industry.

Phthalates and BPA Regulations: Are We There Yet?

It’s better to be safe than sorry.  But the Environmental Protection Agency  recently withdrew two proposed rules regulating chemicals  that it had developed under authority of the Toxic Substances Control Act (TSCA) and submitted to the White House’s Office of Information in 2010 and 2011.  Dr. Richard Deninson  of the Environmental Defense Fund explains it further: Faced presumably with the reality that OIRA [Office of Information and Regulatory Affairs] was never going to let EPA even propose the rules for public comment, EPA decided to withdraw them.  The two proposed rules that were just withdrawn would have: Designated as ‘chemicals of concern’ three classes of chemicals for which evidence is more than sufficient to warrant such a designation:  bisphenol A (BPA), a category of phthalates, and a category of polybrominated diphenyl ethers (PBDEs).  By listing a chemical as ‘of concern,’ EPA may obtain, and provide to the public, more information about the chemical than it

The Science Behind 4 Of The Greatest Polymers Of All Time

PMMA Applications: Lucite, dentures, aquarium windows Developed in: 1877 Polymethylmethacrylate is a very versatile polymer. If you ever see a clear plastic block, it's probably PMMA. It was first commercialized in the 1930s in Germany, and is now found anywhere one needs clear, strong material. This includes bulletproof "glass" at your favorite corner liquor store and the huge shark tanks at the Monterey Bay Aquarium. But my favorite use of PMMA is in so-called "frozen lightning" or Lichtenberg figure sculpture. Basically, put a chunk of PMMA into an electron accelerator, fire a bunch of electrons into the plastic until it's got about two million volts of charge, then touch the side of the plastic with a bit of wire and watch as bolts of lightning carve tracks inside the clear plastic. Superabsorbers Applications: Diapers Developed in: 1960s Back in the day, diapers were made from cloth. Frequently, those cloth diapers were filled with wads of n

Virginia Tech Students Create Foldable Bike Helmets

Helmets: Something you may have hated with a passion as a child, but your parents made you wear. As adults, one could argue helmet use is pretty divided. If you head down your local bike path or along a neighborhood street, you’ll see a good number of riders not wearing their helmets. Two Virginia Tech students think that’s a problem. Co-founders David Hall and Jordan Klein started  Park & Diamond  and set out to create a safe, compact, and stylish helmet to hopefully convince people to wear them every time they bike. The interest in refining technology to prevent bike related head injuries is  incredibly personal  for the team of innovators, especially for Hall. In 2015 Hall’s younger sister was involved in a bike accident in Philadelphia and remained in a coma for four months. The bicycle crash occurred at the corner of Park Avenue and Diamond Street in Philadelphia—which is reflected in the name of their company. How Helmets Work Just like the  crumple zone  in y
