The M&J next-generation preshredder draws on the proud traditions of the M&J PreShred 4000S, M&J Recycling's undisputed flagship in preshredding.
The evolution at M&J continues, and leading the charge is the new M&J P250. It now encompasses a modular design and decreased energy consumption, resetting the industry benchmark and building on its robustness.
The brand-new M&J P250 preshredder points directly into the future. It is stronger than ever, it uses less energy and then it is modular, which has great advantages.
The M&J next-generation preshredder draws on the proud traditions of the M&J PreShred 4000S, M&J Recycling's undisputed flagship in preshredding. Since its introduction, the M&J PreShred 4000S has long established itself as the industry leader in versatility and build quality. The P250 proudly touted as the Next Generation M&J preshredder, builds on the unique DNA of the 4000S, with enhancements that surely will reset industry benchmarks.
With the goal of continuously improving and innovating, engineering has created a modular design driven by the need to simplify maintenance and reduce operating costs.
All of the parts on the M&J P250 can be efficiently removed and replaced as needed. The obvious benefit of this new modular design is the advantage that operators only replace parts that actually are worn, ensuring high uptime in production and large savings on the operating budget because fewer hours and spare parts are spent on maintenance and service. The modular design also makes service work on the machine safer and easier to handle.
The M&J P250 also comes with M&J Recycling's newly developed E-drive solution, which is an obvious choice for many waste types. It offers the same performance as the traditional hydraulicly driven 4000S while reducing power consumption by 50 percent.
“Our main focus has been on creating a preshredder that makes maintenance super efficient, so the customer saves money on the operating budget and minimizes the costly downtime,” M&J Recycling CEO Uffe Hansen says. “The next generation preshredder can be quickly disassembled and reassembled, and you can replace only the parts that are really worn. In addition, it performs superbly on every conceivable parameter, as you would expect from an M&J shredder."
M&J Recycling says it is among the leading global green-tech companies within the waste and recycling industry and its waste shredders help companies around the world contribute to a greener future by utilizing the full potential of the planet’s resources.
As a global green-tech company, M&J Recycling is competitive and driven by results, and its global team is given the freedom, flexibility and support to reach their full potential.

Two West Virgnia University professors hope to create modular equipment capable of processing e-scrap efficiently.
Researchers at West Virginia University, Morgantown, are working to resurrect discarded electronics, recycle electronic scrap and recover minerals from these devices to make new products critical for national defense.
Terence Musho, associate professor of mechanical and aerospace engineering at the Benjamin M. Statler College of Engineering and Mineral Resources, is leading the project, which received more than $250,000 from the Defense Advanced Research Projects Agency at the U.S. Department of Defense (DOD).
The U.S. depends on countries like China to provide raw materials that are essential to manufacturing electronics for its national defense.
“Reliance on foreign national resources has led to the White House identifying a critical shortage in the semiconductor supply chain,” Musho says.
That shortage is one reason the DOD is eyeing readily available electronic scrap, like old “LEDs and microelectronic circuits used for amplifying radio frequencies, which contain critical supply chain materials,” he explains.
One key factor setting apart the research Musho is conducting with Statler Professor Edward Sabolsky from current systems for electronics recycling is the “ability to achieve very high temperatures in a very rapid manner,” which should allow their technology to be modular and portable, Musho says.
“That means the DOD can transport this technology around to the point of disposal of these e-waste materials,” Musho says. “Space debris is an issue that’s gaining attention, so one far-out idea is that this potentially could be used in space. You could collect junk satellites, recycle the waste and bring the raw materials back to earth. Another possible application would be [on] U.S. Navy ships, which could move this equipment around to different ports for waste recycling.”
The technology also has promise beyond the sphere of national defense.
“You could have a point-of-disposal e-waste recycler in each community,” Musho says. “Communities could recycle their own e-waste, get the raw materials out and sell those materials back to manufacturers.”
The precious and rare-earth metals used in electronics often are recovered using pyrometallurgy or hydrometallurgy. Those processes use either high temperatures or hazardous chemicals to extract minerals from electronics and both require large quantities of input material to be economical.
Therefore, the DOD has focused on recovering seven specific elements from e-scrap, chief among them gallium, indium and tantalum.
Musho will use computational thermodynamics to simulate the mineral recovery process, and Sabolsky will validate the simulations to prove the process works in practice.
Musho says he is confident that it will work, especially because Sabolsky’s previous research laid the groundwork for this study.
“Ed did a previous study on coal fly ash, a waste product of coal-fired power plants, and he demonstrated that this process works for other critical elements present in fly ash,” Musho says. “Now, we’ll take that knowledge, improve upon it and apply it to e-waste.”
The project’s first phase is a nine-month study demonstrating Musho and Sabolsky’s e-scrap recycling process in the lab.
After that, they say they plan to refine the approach to “hit tighter purity standards” for the recovered minerals. They also will scale up to process greater quantities of material and work on packaging the technology within a small, modular unit that’s easily transported as they begin to consider commercialization.
“We have an abundance of critical materials currently sitting in e-waste in our landfills,” Musho says. “It’s just a matter of determining the best method to recover these elements. The technology we’re developing provides a supply chain solution not only for DOD electronics but also consumer electronics.”
The county purchased the Mack LR Electric in May to help meet its goal of zero emissions by 2050.
The Miami-Dade County Department of Solid Waste Management (DSWM) in Florida has introduced its first-ever electric-powered waste collection vehicle.
The department purchased the LR Electric refuse vehicle from Greensboro, North Carolina-based Mack Trucks in May of this year. A prior release announcing the purchase states the LR Electric model will be used in residential route collection for Miami-Dade County.
According to Congresswoman Frederica Wilson, Miami-Dade used funding opportunities and support from the federal government to help its transition to zero-emission refuse trucks.
“Initiatives like these are a big step towards environmental justice and with the help of the Inflation Reduction Act, we are going to invest even more in cleaner trucks and buses that we use every day at every level of government—from here in Miami-Dade County up to the halls of Congress,” she says.
DSWM says the new vehicle will undergo yearly maintenance, allowing for significant cost savings when compared to the quarterly maintenance required for the department’s fossil fuel-powered vehicles. Additionally, powering the vehicle with electricity produces zero emissions and significantly reduces noise when compared to diesel engines.
“This truck represents our countywide commitment to climate action and brings us one step closer to our goal of net zero emissions by 2050,” says Miami-Dade County Mayor Daniella Levine Cava. “This electric-powered waste collection truck joins a growing county-wide fleet of clean vehicles as we work to reduce the county’s carbon footprint, preserving and protecting our community for generations to come.”
At current fuel pricing levels, DSWM expects to see a return on investment within five years. The vehicle will be parked and recharged each night at the county’s Resources Recovery waste-to-energy facility.
“This electric truck is a testament [to] what smart policies can do, to think that the waste-to-energy facility can be the source of powering this truck, this puts Miami-Dade County in a very unique position to truly use clean energy, [or] non-fossil fuels. We are going to see a future of cleaner air in our county with this vehicle and others like it that will potentially be powered by the same facility and hopefully get us off the grid resulting in savings and efficiencies for taxpayers,” says Jose “Pepe” Diaz, Miami-Dade County chairman.
DSWM Director Mike Fernandez adds, “The waste this truck picks up during the day will be incinerated at the Resources Recovery Facility, creating the electricity to recharge the truck at night. This will be the first automated side loader waste collection vehicle in the U.S. that will be powered by the very waste it collects. This will be a full-circle process.”
The DSWM provides waste collection and disposal services to more than 340,000 households in unincorporated Miami-Dade County and the municipalities: Aventura, Cutler Bay, Doral, Miami Gardens, Miami Lakes, Opa-locka, Palmetto Bay, Pinecrest, Sunny Isles Beach and Sweetwater.
