Check Out the New Purging Compounds Knowledge Center

By: James Callari 14. May 2014

Earlier this month we launched a new Knowledge Center on the Plastics Technology website. Sponsored by Asaclean, this Knowledge Center focuses on the matter of purging.

 

Whether you run a single extruder in a university lab, or 30 injection molding presses in a Tier 1 automotive supplier, sooner or later you will need to purge your machine. Some of these reasons are beyond your control, but one thing for certain is: which material you use to purge your screw and barrel.

 

Navigate this Knowledge Center and tap into information on purging compound basics, purging for injection molding and extrusion, purging tips on hot runners, and troubleshooting. There’s also a FAQ section and a place where you can direct a specific purging questions to an Asaclean expert.

Did You Miss Our Drying Supplement?

By: James Callari 14. May 2014

 

As a subscriber to Plastics Technology you should have received by now a supplement that was polybagged with our May issue. It was called Drying Done Right and it is chock full of advice on materials drying from experts in the field, including leading processors. If it’s sitting on your desk, I suggest that you open the bag and take a look (of course give the regular issue a thorough read too). I think you’ll want to keep it handy and will be referring to it often.

If you can’t get your hands on it—perhaps one of your colleagues lifted it?—then click on this link and go to our digital edition. You can download the entire issue as a PDF and circulate it among your associates. Or if you prefer you can access on via our online archives.

Happy drying.
 

Printpak Spearheads Local Effort to Recycle Rigid Plastics

By: James Callari 1. May 2014

 

At a time when plastics are being challenged on a regular basis by governments, James City County in Virginia along with three other and Virginia municipalities have joined the ranks of more-progressive lawmakers by making accommodations for their residents to include rigid plastics in their curbside pickup for recycling.

 

Starting in July 2014, residents in these areas will be able to include plastics like yogurt cups and grocery store clam shells, among other plastic containers in their recycling bins.

 

The initiative was driven by Printpack Rigid, and Jamie Clark, its v.p. and GM.  One of Printpack’s U.S.- based rigid plastics processing plants, which produces sheet rollstock and a variety of barrier PET-based cups for applesauce, pudding, tuna and a variety of other applications, is located within James City County, where Clark also calls home.  As an officer of the Society of the Plastics Industry (SPI) and the chairman of the SPI’s Rigid Plastics Packaging Group (RPPG), Clark helped support a study on rigid plastics recovery within the county.

 

The Virginia Public Service Authority (VPPSA),  which manages curbside collection for the four municipalities, led the initiative with support from Printpack and RPPG.  The study showed when households were asked to recycle all of their rigid plastics, the entire quantity of recyclables went up by 20% with polypropylene and non-bottle PET making up the majority of the increase. Even PET bottles, which are already included in the program, saw a substantial bump. 

 

National recycling statistics show a trend in improvements in the recovery stream for rigid plastics.  Non-bottle rigid plastic recovery has increased threefold since 2007 to 2011 from about 325 million lb to 934 million lb.  In addition, the ratio of materials staying in Canada and the U.S. as opposed to shipping to other countries has increased from 37% to 61%, which is higher than aluminum and paper.

 

Initially, the VPPSA was reluctant when collection of all rigid plastics for recovery had originally been put on the table for discussion, Clark recalls. The market for mixed plastic seemed to be centered overseas, and VPPSA wanted assurances that if it were collected, it would actually be recycled.  Traditionally, the only plastic material they accepted was PET bottles and HDPE jugs with necks.

 

As the project progressed, VPPSA put their contract for collection out to bid.  But they did not include all rigid plastics in the RFQ because they were concerned that there wasn’t enough economic incentive to collect the material. VPPSA was also concerned that they might even see cost increases if they included all rigids.

 

After extensive research on this matter, Jamie Clark ensured them that the domestic market was developing to handle this type of recovery. “The expanded recycling won’t cost the localities more nor require a change in the regional contract.  There is enough market for the materials that contractors seem to be looking for more of this mixed plastic to buy,”  Clark states. He adds, “The scale of manufacturing in China shows the level of polypropylene consumed is three to four times of that in the U.S.  We should not be surprised that Asia has high demand for this raw material. This is a good thing.”

 

HAMMERING OUT THE DETAILS

 

This past January, Printpack executives and representatives from the SPI, the Southeast Recycling Development Council, County Waste, the MRF (the company that won the bid), and James City County’s Economic Development and General Services Departments met to work out the program’s details. “The meeting was targeted to roll up our sleeves and figure out how to expand plastics recycling locally,” said Clark.  County Waste came in with the attitude of, ‘we’re ready to do it, we’re already doing it elsewhere, so let’s roll.’ County Waste clearly understood that maximizing collection and recycling of all rigid plastics was profitable.

 

James City County Economic Development Group was instrumental in aligning the parties and moving this initiative forward.  Clark added, “There is good reason that Forbes Magazine ranked Virginia the best state for Business in 2013.”

 

Citizens of the county can expect a simple procedure of simply separating out their plastics in a separate bin to be picked up with regular waste disposal.  With local industries and citizens at large aligned, this no cost solution to aid in the recovery of plastics is projected to be a hit in this community.

Step Up and Support Manufacturing Day

By: James Callari 16. April 2014

The third annual Manufacturing Day is coming up Oct. 3. Far away, you might think, but close enough that you maybe start planning if you intend to participate.

 

Manufacturing Day, for those who don't know, is an important day for any company that makes things to show off their businesses, technology and the products they make to students, parents, teachers, and job seekers who are interested in learning about manufacturing and the skills and training needed to start a career in the field. To strut their stuff, as it were.

 

I believe plastics processors need to take this event more seriously.

 

The second annual Manufacturing Day was held last Oct. 4. On that day, more than 825 manufacturers in 48 states opened their doors to in excess of 35,000 guests to show what manufacturing is all about.  “Manufacturing Day 2013 was a success because hundreds of manufacturers invited their communities—including students, educators and legislators—to visit their operations and see first-hand the value of the work they do”, states Ed Youdell, president and CEO of the Fabricators & Manufacturers Association.  

 

Youdell added: “By focusing the events of so many manufacturers around a single day, participants collectively delivered the message that manufacturers are of significant importance to the U.S. economy, are well-managed companies that can compete globally, and offer family-supporting careers to students who follow technical and community college paths as well as four-year degree programs.”

 

Manufacturing Day gives companies a chance to inform the general public about the issues they face, such as a shortage of skilled labor. During the events they hosted, many manufacturers reported how this shortage affects them on a day-to-day basis, as well as the solutions they are developing to tackle it. That message was delivered not just to the 35,000 visitors at local events, but to more than 80 million viewers of the website and social media postings.

 

“At The Manufacturing Institute, we are working to help manufacturers attract quality talent and develop the workforce pipeline,” noted Jennifer McNelly, president of the group . “When we all work together, manufacturing is stronger, and when manufacturing is stronger, the U.S. is stronger.”

 

“The robust response and participation in Manufacturing Day from across America shows manufacturers’ commitment to developing the talent needed for a 21st-century workforce,” added Jay Timmons, president and CEO of the National Association of Manufacturers. “By opening shop floors to young and curious minds around the country, we are able to show that modern manufacturing is a technology-driven industry that offers secure, good-paying jobs and the ability to develop products that will change the world.”

 

But of the 800+ manufacturers that opened their doors to interested people last October, only a handful—fewer than 10—were processors. That’s a disappointing number at any point, particularly when this industry, like many others, is having enormous challenges finding young talent.

 

One processor that took part in the 2013 festivities was Plastic Molding Technology (PMT), El Paso, Tex. "The goal of the Manufacturing Day event at PMT was to draw greater attention to the outstanding opportunities a career in manufacturing can provide, and to promote the pursuit of skills leading to a long-term career for qualified candidates," said Charles A. Sholtis, owner and CEO of the company. “Manufacturing is coming back to the U.S.,” Sholtis added. “The role of manufacturing in the supply chain has become increasingly important to end markets. Hopefully, by opening up shop floors around the country to students and other businesses, we were able to show modern manufacturing for what it is—a sleek, safe, technology-driven industry that offers secure, good-paying jobs.”

 

 

Bill Carteaux, president and CEO of the Society of the Plastics Industry, put it this way: “A high-quality manufacturing sector is vital to our nation’s ability to thrive within a global economy. It’s important that we invest financial and human resources into expanding manufacturing so that we can continue to create American jobs and grow our economy. Companies that participate in Manufacturing Day help secure the future of the plastics industry by promoting its innovative technologies and opportunities.”

 

PMT plans on participating again this year, and expects a bigger turnout at its plant than last year. Why don’t you give it some consideration? Log on to mfgday.com to learn how to get involved.
