Whether it’s scanning incoming loads or monitoring scrap throughout processing, the GammaView from S.E. International Inc. is the ideal choice for detecting high levels of gamma contamination.
One of the various challenges faced when processing scrap metal is the potential for incoming loads to contain radioactive materials. The consequences of not catching these materials early in the process can be dire and result in a very costly cleanup effort.
This includes the tricky hunt for the source of contamination after the initial alarm is raised. Having quality instrumentation to help can be the difference between a relatively smooth operation and a rocky road with many potholes. This is when the Radiation Alert GammaView from S.E. International Inc. comes in handy. Its intelligent design, accompanied by high levels of sensitivity and accuracy, makes it ideal for circumstances such as these.
Radioactive contamination of scrap metal can occur for a variety of reasons. Most of the time it’s the result of small amounts of contaminated material being improperly disposed of. This could be due to not being labeled correctly or a lack of awareness about what’s being discarded.
Either way, the result is the same, and companies end up with an entire load that needs to be rejected. Even though finding these materials can be hard, it’s better to do it when it first arrives at a facility than to discover it further along in the process. Processing radioactive materials unknowingly brings the potential for cross-contamination with much of the inventory. Cleanup can be costly and dangerous as operators risk exposing workers to radiation.
Most of the time, a piece of contaminated material is discovered by the large portal monitors that scan the incoming trucks first. Once an issue has been confirmed, further inspection with a hand-held survey meter can help pinpoint the exact location of the radiation source.
Companies will begin their surveys by establishing a background count. Normal background radiation levels vary at different locations, different times and in different areas of the same room. To accurately interpret the readings you get, it is good to establish normal background radiation counts for each area the company plans to monitor.
The GammaView is intuitive and makes this task a simple process of navigating the easy-to-use interface. Directions for performing a timed count are readily accessible in the operations manual and on our website. After the company has determined normal background for its area, scanning can begin.
The operator needs to get close to the object being surveyed without contaminating the detector. The GammaView comes equipped with a highly sensitive sodium iodide detector. This determines the appropriate distance with greater ease and accuracy.
After determining the correct distance to start, the scan can begin. Generally, operators will want to move the detector no more than 2-3 inches per second, all the while making sure to pass over as much of the area to ensure that nothing is missed. The ergonomic compact design and portability of the GammaView make it ideal when performing a task of this nature.
While scanning, operators can listen to the beeper and view the counts on the graphic display to determine if any levels are above average background. The device will chirp faster when high levels of radiation are detected. The counts displayed on the unit will also increase in value. The GammaView’s graphic display is easy to read and comes with a backlight function.
The Radiation Alert GammaView was designed to tackle these events in a way that alleviates some of the pitfalls of radiation surveying. For more information, click here or call 931-964-3561.
American Recycling of Western North Carolina processes roughly 30,000 tons of recovered fiber annually in Asheville, North Carolina.
Sonoco Recycling, a unit of Hartsville, South Carolina-based packaging producer Sonoco, has announced its purchase of American Recycling of Western North Carolina, a privately owned paper recycler in Asheville, North Carolina.
American Recycling of Western North Carolina processes approximately 30,000 tons of recovered fiber annually. The business expects to generate approximately $9 million in sales in 2021 and it is strategically located approximately 65 miles from Sonoco’s Newport, Tennessee, uncoated recycled paperboard mill, Sonoco notes in a news release announcing the purchase.
“This acquisition provides Sonoco’s mill operations with a stable, lower cost supply of recovered fiber with the opportunity to grow volumes in the region,” says Palace Stepps, division vice president and general manager of Sonoco Recycling.
Sonoco Recycling collects approximately 2.8 million tons of old corrugated containers, mixed paper, metals and plastics through its five material recovery facilities and 20 recycling centers annually, serving more than 100 communities.
The transaction is expected to close in the first half of 2022, Metso Outotec says.
Helsinki-based Metso Outotec says it has signed an agreement to divest its Metal Recycling business line to an affiliate of Mimir, an investment company based in Stockholm, with the transaction expected to close in the first half of 2022. The parties have decided not to disclose the value of the transaction, with Metso Outotec adding that the divestment will not have a material impact on its financial results.
The Metal Recycling business that Mimir purchased includes the Lindemann and Texas Shredder brands. The business will change its name in conjunction with the divestment and operate globally under the Lindemann brand, with headquarters in Düsseldorf, Germany. The business unit's nearly 160 employees will transfer to the new company in connection with the transaction. The net sales of the business totaled 77 million euros (nearly $87.4 million) in 2020.
Metso Outotec announced its intention to divest its recycling businesses in late October 2020. These businesses have since been reported as part of discontinued operations in Metso Outotec’s financial statements. The divestment of the company’s Waste Recycling business to Helsinki-based Ahlström Capital’s fully owned investment company Ahlstrom Capital BV was completed earlier this December.
Piia Karhu, senior vice president, Business Development and Metal Recycling business line, at Metso Outotec, says, “We are delighted that going forward, the Metal Recycling business will continue to implement its strategy together with the new owner Mimir. As an established standalone company, its full focus will be on the metal recycling markets and customers.”
“This is a great opportunity for Metal Recycling to take the next step in our development,” says Ioannis Giouvanitskas, vice president of Metso Outotec Metal Recycling. “Mimir has the resources to quickly expand our leading market position and to be able to provide our products and services to a growing, global customer base.”
Joakim Notö, managing partner and group chairman at Mimir Invest, says, “We warmly welcome Metso Outotec Metal Recycling to Mimir and look forward to driving growth for this attractive business together with its employees.”
He adds, “Metso Outotec Metal Recycling is a typical Mimir investment, being carved out from a large corporation with leading technology and engineering expertise that positions it among the premium brands in its markets.”
Mimir is a global investment firm acquiring non-core business units of large corporations as well as private companies that need operationally oriented ownership. The Mimir group has operations in 20 countries worldwide, employing 1,200 people.
Recycling represents a tangible solution for climate action and is an engine for economic development.
Recycling market development is not a new concept. In the 1990s, the U.S. Environmental Protection Agency (EPA) created programs to try to drive recycling and recycled-content use and purchasing. Programs such as Jobs Through Recycling (JTR) included funding for grant programs like Recycling/Reuse Business Assistance Centers and Recycling Economic Development Advocates and facilitated a network of recycling market development professionals.
The 1997, the U.S. EPA publication “Jobs Through Recycling Program: What is the Connection Between Jobs and Recycling?” described the JTR program and its grant funding as supporting local companies using recovered materials with technical, business, financial and market assistance, including writing business plans, securing financing and assessing the marketplace for recovered materials.
These programs did affect jobs and recycling in the U.S.; however, support wanned—both political and financial. Initially, federal programs and mandates drove recycled-content purchasing within the government, but the private sector lagged behind. As political views shifted, so did the funding. Though results could sometimes be uneven or programs unexpectedly discontinued, these seminal efforts helped lead to the development of the current nationwide recycling system.
Since the turn of the century, overseas manufacturing was expanding in light of its low-wage labor advantages and cost-effective overseas backhaul capacity. Strong trade trends made recyclable bales from Europe and North America very attractive. Over time, the capacity to use these recyclables outpaced supply. Consequently, export markets were accepting lower quality, off-specification bales to ensure supply requirements.
The focus for large importing mills that could handle more contamination became capturing a quantity of recycled materials. North American suppliers increased supply through convenience-sensitive single-stream collection programs and sped the mixed materials through material recovery facilities (MRFs) without removing all the contaminants. With little direct negative feedback in the form of rejections and downgrades, U.S. suppliers pushed the limits on contamination to meet supply demands. U.S. recyclers became comfortable with the export market and lagged in innovation to match the evolving recycling stream and packaging materials.
Smaller overseas mills and processors did not have the technology to deal with the contamination included in the commodity bales. That led to increased pollution in those countries. The Chinese government started to crack down on the contamination via increased inspections with its Green Fence and National Sword policies.
“The situation became untenable for regulators in those markets,” Michael Timpane, vice president of process optimization and material recovery at RRS, says. “The supply chain partners were missing the point that, though recycling is an essential input for manufacturing, off-spec materials with high contamination led to high disposal costs, lower yields and, in many cases, illegal dumping of plastics and paper contaminants into the environment, especially at smaller uncontrolled mill sites.”
When China instituted restrictions, other markets, such as Vietnam and India, started to take a large portion of materials that initially was going to China. But those markets, too, started to have similar issues with underperforming mills and the perception that the West was dumping its offal in their homelands. Inspections and bans followed in those destinations as well.
Overseas mills established their own MRF infrastructure and ramped up recovery domestically. In addition, large Asian mills started buying assets in the U.S. to generate materials to send to their manufacturing facilities overseas as either an intermediate pulp-state product or as a finished paper product.
“U.S. collection programs were under financial stress due to the decrease in commodity value and the need for capital investments to improve technology to meet higher quality specifications,” says Sean Duffy, associate senior consultant with RRS and former president and chief operating officer of ReCommunity LLC, a MRF operator.
The market disruption cascading from National Sword and a growing chorus of outcry over environmental impacts related to recycling exports, particularly around the issues of ocean plastics and unregulated waste dumping/burning, led to a reinvigorated focus on domestic recycling market development. Improving domestic recycling markets was seen as a primary solution to make the U.S. recycling system more resilient and responsible while providing the supply chains necessary for brands to fulfil emerging goals around recycled content.

Policymakers and state agencies also are circling back to the notion that the recycling industry can be an effective economic development engine with triple bottom line benefits: people, planet and profit. Conditions are more favorable than ever to support recycling market development in light of technological advances and strengthened demand for recycled content through voluntary and mandatory requirements.
Recycling market development centers are entities or programs that typically are established and/or funded by state government. They are focused on improving recycling markets by supporting businesses that use recycled materials, bringing together resources, providing expertise and tools to coordinate strategies and overcome barriers and working to achieve positive environmental, community and economic outcomes.
States that had recycling market development programs since the 1990s and early 2000s, including Minnesota, South Carolina, Pennsylvania and Michigan, have been reinvigorated with a sense of urgency and added resources, while several states, including Washington, Colorado, New Jersey, Maryland and New York, have begun developing new recycling market development centers,.
Recently, AMERIPEN and RRS published the report “Best Practices for State Recycling Market Development Centers” based on research into leading centers nationwide that highlights elements for state governments and related stakeholders to consider when establishing or improving recycling market development centers. Fundamental to a successful program are a proper establishing framework, implementation and operational funding, operational structure and programming tools and resources:
"Recycling market development centers serve an important function to facilitate collaboration, innovation and partnership along the entire recycling value chain,” says Will Sagar, executive director of the Southeast Recycling Development Council (SERDC), Hendersonville, North Carolina. “This function is essential to connecting many of the disparate pieces within the recycling system, allowing domestic recycling markets to grow and thrive.”
State agencies play a key role in establishing and funding the center but also must engage a range of public and private partners, including local governments, collection and processing operators, reclamation and end market manufacturers, research institutions and trade organizations. There is no one-size-fits-all approach, however. Rather, each state has the opportunity to customize the approach based on local conditions.
According to the “Post-consumer Plastics Recycling Data Report,” from 2010 to 2019, U.S. postconsumer plastic recovered for recycling shifted from an approximate 40 percent/60 percent export/domestic ratio to an approximate 10 percent/90 percent ratio. The COVID-19 pandemic has had a major impact on global supply chains for all products, and domestic supply chains could prove to be more reliable.
Additionally, U.S. paper mills are expanding and converting as a result of overseas regulations and increased demand for packaging, especially boxes, because of COVID’s impact on e-commerce.
“The U.S. recycling and manufacturing industries need to see each other as partners in creating products with recycled content for the consumer,” says Dan Felton, executive director of AMERIPEN, St. Paul, Minnesota. “A collaborative effort is needed to improve commodity bale quality and create domestic end markets for these materials.”
Recycling should no longer be seen as simply an environmental practice that prevents material from going to the landfill. Recycling represents a tangible solution for climate action and is an engine for economic development, creating jobs and local investment in communities. The timing is right, and the opportunity is here for communities, recyclers and manufacturers to align and collaboratively drive growth and move forward toward a truly circular economy.

A briquetter supplied by Weima helps the company manage its production scrap.
The city of Peoria, Illinois, is home to eyeglass manufacturer Maui Jim, which is known for its fashion-forward approach to sunglasses and prescription eyewear.
The company’s sustainability goals increase the value of its products to modern consumers as Maui Jim has taken steps to implement green practices during production and recycling initiatives for its end-of-life products.
The process of creating custom lenses involves loose, airy scrap and cutting fluid. Each lens starts out as an 11-millimeter-thick piece of plastic that is machined and polished to the correct shape and thickness.
“As we start the whole process of making a pair of prescription lenses, they go into what we call an orbit lens generator,” Paul Ponder, vice president of prescription manufacturing at Maui Jim, says. “It creates swarf as it cuts that lens down to prescription shape and thickness. That swarf is flushed out with a fluid, used to cool the lens during the cutting process. It is also used as a wetting agent to flush it through the evacuation tubes. That fluid, which is taking the waste out, is cleaned back up and then comes back to the machine for reuse.”
Bazell Technologies has worked with Satisloh to provide the best-in-class coolant delivery equipment that Maui Jim uses to generate lenses. The engineers at Bazell worked with Weima, a German company with a U.S. sales and service office in Fort Mill, South Carolina, to select the right briquette press for the job—in this case, a Vario model—to compress the lens swarf and separate the cutting fluid for reuse.
The shavings, once they have been separated from the cutting fluid, are then conveyed from the cleaning unit to the Weima briquette press. The machine sits in its own designated space just off the production floor. Its footprint is minimal, but its presence in the process makes it possible to recycle the fluid and the swarf.
“It takes the processing of the debris off the production floor and saves space,” says Paul Dick, president and managing director of Bazell Technologies, Concord, California. “This allows space for more lens generators on the production floor.”
With 12:1 compaction rates, Maui Jim saves space by processing scrap created during production shifts instead of storing it in its original form. The briquette press compresses these shavings into round, puck-shaped briquettes that are then picked up by a recycler to be transformed into postconsumer resin, or PCR, and integrated into other material streams.
Maui Jim found that the cost for the recycler to pick up this scrap was comparable with the landfill fees they would accrue. The value of this landfill diversion added to the reasons why Maui Jim opted to recycle this material instead.
Maui Jim’s recycling efforts don’t stop there. The lifetime warranty on each pair of Maui Jim glasses extends to lenses and frames. Each time a pair of glasses is sent in for minor repairs, the frames and/or scratched lenses are also picked up by a recycler to be made into new things. The consumer will receive a pristine pair of glasses, and the damaged frames or scratched lenses leave the facility to be given a second life.
“Certainly, we want to be environmentally friendly, doing everything we can to keep anything from going to a landfill,” Ponder says. “All our lens waste, all our frame waste, any defects or rejects—it’s all recycled. Our frame designers are always looking at ways to be environmentally friendly.”
