Our mantra has always been, “Wear Tough, Runs Long.” Whether times are tough or not, costs matter. We’re now bringing that same focus to plastic wear parts.

As the owner or operator, you’re constantly tasked with doing more with fewer people, stretching maintenance periods, and looking for the most competitive prices.

You also have to keep on top of trends and technology changes that improve efficiencies. With advances in single stream municipal recycling, larger scrap yards are now experimenting with roll screens for improved ferrous recovery.

Our customers in the recycling space are beginning to work with roll screens in sizing non-ferrous and fluff for the processing side of their operations. Roll screens have a major advantage due to their ease of adjustability in dealing with compressible products.

As with everything in metals recycling, adapting technologies used elsewhere has its drawbacks too.

The Start of Metal Recycling and Its Current Impact: WW2 Scrap Drives

Legend has it that one of the first contracts the U.S. Continental Congress penned was for muskets, which were to be used in the Revolutionary War effort. The Founders then penned another for gathering the scrap metal needed to help supply the craftsmen that made the muskets.

Revolutionary War muskets (or long guns) were actually made from wood with metal parts, which included the steel bayonets.

However, it stands to reason that the newly created Congress pushed for weaponry and other war items to be manufactured from recycled material whenever possible: the fledging United States was cash strapped.

According to information at Recycle Nation, George Washington urged the reuse of worn chains from frigates, while Paul Revere advertised for scrap metal of all kinds.

The American Civil War also saw collection for recyclable materials for both the North and South. People donated church bells, steeples, pots and pans – anything that could be used for the war effort.

But other than wars, when the need for metal was great, Americans didn’t consistently recycle metal goods. In fact, when World War 2 began, an “estimated 1.5 million tons of scrap metal lay useless on U.S. farms – enough to build 139 battleships weighing 900 tons each, 750,000 tanks 18-27 tons each, or countless airplanes, weapons and other materials.” (Source)

Navigating the Current Economic Cycle:
From Peak to Bottom to Recovery

Tom Stanek

Financial data on a monitor,Stock market data on LED

The term “commodity super cycle” is something I’ve been hearing regularly. Most metal recyclers believe we’re in a super cycle; I wanted to know how business owners can navigate this type of cycle, as well as how it plays out from peak to wind down.

I turned to my colleague, David Hunter. A 48-year financial market veteran, David’s experience includes managing global portfolios and equity pension funds, as well as market forecasting.


Tom: Are we in a commodity super cycle?

DH: First, let’s define it. A super cycle is a cycle that is unusually long in duration and very extreme in bottom to top price movement, far beyond what is seen in normal cycles. For example, I believe we are in the last decade of an economic super cycle, which I define as the period between two depressions, the last being the Great Depression of the 1930s and the next depression being one that I expect to hit in the 2030s. Within a super cycle are many shorter economic cycles with upturns and recessions.

Right now we are hearing a lot about a commodity super cycle because after decades of flatness, commodity prices are beginning to break out and show major price strength. I think it is premature to say we have entered a commodity super cycle because I expect a sharp economic downturn in the second half of 2022 to send commodity prices back down — and down sharply. All sectors of the global economy will be hit hard by this downturn, including commodities.

There will be a strong recovery beginning sometime in 2023 fueled by massive fiscal and monetary stimulus. It will be focused on infrastructure, and we’ll see similar expansion across the globe. Unlike recent recoveries, this one will not be led by the consumer. Rather, it will be an industrial-led recovery.

As a result, demand for commodities will surge and remain strong through the decade. This will drive commodity prices ever higher for several years. We will see prices of all commodities soar to levels few can imagine today. This will be the commodity super cycle.

As I like to say, thinking the commodity prices go straight from here into that super cycle is the equivalent of standing on the South Rim of the Grand Canyon and looking at the North Rim and thinking it is just a short walking distance away because one failed to account for the canyon that lies between the two rims. The same is true of commodities. There is a big canyon in the form of a global bust that lies between the current strong commodity boom and the big commodity cycle that will follow the bust.

When Is It Time to Change Shredder Hammers?

Tom Stanek

shredder hammers

When do you know it’s time to change your scrap metal shredder hammers?  What does it mean to “change” hammers?

Changing hammers refers to both replacing hammers with new, as well as “flipping” or “turning” hammers to another side to expose a fresh leading edge, or rotating hammers to a new position on the rotor.

The Lifecycle of Catalytic Converters – and What It Means for Scrap Metal Dealers

Note from Tom Stanek:

In May, our team attended a few sessions of ISRI’s virtual conference – including one on catalytic converter theft, which is rapidly rising due to the precious metals they contain.

ISRI is reaching out and educating scrap metal dealers about this topic in order to stop legitimate dealers from purchasing stolen converters.

In order to better understand why thieves have focused on stealing these items, I turned to Nigel Dove. The founder and CEO of Vortex De-Pollution & Recycling Equipment, Nigel knows his stuff backward and forward. He and his company have a conscious dedication to the client and making the depollution process safe and productive.

In this guest post, Nigel shares with us the lifecycle of catalytic converters – which is quite eye-opening! – what makes them so valuable, and how you, the scrap metal dealer / yard owner or manager can determine legitimate converter scrap versus stolen items.


 

Catalytic converter theft is rampant because that’s where the money is. One converter can net a thief $300. Twenty converters can net a thief or ring of thieves $6,000 – a nice haul for an hour or less of effort.

Catalytic converters are very easy to remove – all that’s needed is a $20 Sawzall and a minute or two of uninterrupted time.  One thief or a few working together can clear out entire parking lots. Think long-term parking at airports, rental car fleet lots, and new vehicle holding lots.

What makes a catalytic converter so valuable? The precocious metals they contain.

Metal Casting “Lightweighting” Trends: Impacts for Automotive Recycling Yards / Shredders

Tom Stanek

metal-recycling - lightweighting

Andrew Halonen of Mayflower Consulting presented at the AFS Metalcasting Congress 2021 about the trends of reducing weight in metalcastings (aka “lightweighting”).

This topic is of interest to the metal recycling industry in particular. As vehicle designers work to reduce weight in order to meet federal and state fuel economy guidelines – as well as reduce vehicle manufacturing costs – fewer ferrous casted parts will be needed.

Although more manufacturers are incorporating lightweighting into their designs, the changeover is still met with some resistance. Halonen cited four reasons: Cost, system over component, changing the supply chain, and other material innovations.

Once a manufacturer decides to change the material makeup of a part – for example, moving from aluminum to an aluminum alloy or other material – the manufacturer is forced to seek out new suppliers. Vetting new suppliers and their facilities and processes is costly and time-consuming.

And, while a manufacturer may redesign one part to be lighter, other parts are redesigned to incorporate more steel or iron depending on load, wear, function, etc. – negating the overall weight savings.

In one example, Halonen compared the 2019 Mustang Convertible with the 1969 Mercury Cougar XR7 Convertible. Both vehicles feature the same platform – yet in 50 years, only 11 pounds have been shaved off the weight!

EPA Releases 2018 MSW Facts and Figures; Ferrous Metals Recycling Up 3%

Tom Stanek

The EPA released its comprehensive report for Municipal Solid Waste (MSW). The report covers all materials recycled, landfilled, composted or combusted with energy recovery in 2018.

Overall, metals (ferrous, aluminum, and other) accounted for close to 9% of total MSW – or 292 million tons.

Ferrous

The largest source of ferrous metals (steel and iron) in MSW are found in durable goods such as appliances, furniture and tires. The numbers below don’t include ferrous materials found in construction materials and transportation products, including automobiles.

Key figures for 2018

  • Ferrous metals generated: 19.2 million tons (6.6% of total MSW)
  • Total recycling rate: 60%
  • Durable goods: 28% (4.7 million tons)
  • Recycling rate steel cans: 71% (1.1 million tons)

Landfills received 10.5 million tons of steel in 2018 – representing 7.2% of all MSW landfilled. (View all ferrous metal data.)

Post COVID: Preparing your recycling facility for infectious diseases and illnesses

Tom Stanek

metal-recycling-post-covid

COVID-19 has highlighted industrial sanitation issues often difficult to address in recycling facilities. How a recycling facility responds to an infectious outbreak depends on the severity and type, as well as orders from the state and/or local government.

In response to COVID-19, for example, some cities in Massachusetts stipulated that canteen trucks were no longer allowed at industrial facilities or construction sites. Workers and facility managers had to scramble to cover some on site meal prep while trying to improve hygiene and sanitation.

And too, the facility’s size and type will dictate the response needed. A large wholesale scrap yard receiving 24 hours, 6 days a week has different considerations than a smaller retail operation open 5-6 days a week.

In a piece for the July/August 2020 issue of Scrap magazine, we cover the three long-term changes facility owners and operators will need to consider post-COVID.

These considerations include:

  • Having a written plan with the rules spelled out.
  • Upgrading temporary facilities by adding handwashing or sanitizing stations.
  • Centralizing employee break areas that share plumbing and are easy to clean and restock with PPE and other supplies.
