LEE also offers training programs to help operators optimize press performance, ensuring clients get the most out of their investment. With the global lithium battery recycling market projected to hit $18 billion by 2030, LEE is poised to remain a key player.

For recyclers focusing on circuit boards and scrap cables, Rhine Valley Industrial Solutions (RVIS) in Schaan is a household name. The company's expertise lies in filter presses that bridge the gap between dry and wet process equipment—a critical advantage for circuit board recycling, which often involves both grinding (dry) and chemical leaching (wet) stages. "Circuit boards contain a mix of metals, plastics, and resins, so the waste stream is complex," says RVIS sales manager Thomas Koch. "Our filter presses can switch between separating acidic leachate (wet process) and capturing dust from shredders (dry process) with minimal reconfiguration." The company's CB-2000 filter press is a favorite among clients running circuit board recycling equipment, as it integrates with RVIS's own cable recycling equipment, including scrap cable stripper machines. Koch highlights the presses' durability: "We use corrosion-resistant materials like Hastelloy in the plates, which extends lifespan in harsh chemical environments." RVIS also offers a unique "try before you buy" program, letting clients test filter press performance with their actual waste samples—a service that has earned it a loyal customer base in Asia and North America.

When it comes to heavy-duty industrial recycling—think metal scrap, hydraulic briquettes, or large-scale baling—Princely Engineering Works (PEW) in Triesen is the supplier of choice for many global players. Founded in 1965, the company cut its teeth building hydraulic press machines equipment for the automotive industry before pivoting to recycling, bringing that same rugged engineering to its filter presses. "Our clients process everything from shredded car bodies to aluminum cans, so their filter presses need to withstand abuse," says PEW's managing director, Sofia Müller. The company's HP-5000 filter press, designed for high-pressure applications, can generate up to 250 bar of pressure, squeezing moisture out of dense materials like hydraulic briquettes or metal chips. PEW also pairs its filter presses with hydraulic baler equipment, creating a closed-loop system where waste is compacted, dewatered, and ready for melting or resale. "We recently supplied a plant in Germany that processes 20 tons of metal scrap daily—their PEW filter press has run nonstop for three years with only routine maintenance," Müller notes proudly. For recyclers dealing with high-volume, heavy materials, PEW's reputation for toughness is unmatched.

Alps Clean Tech GmbH, based in Balzers, takes a holistic approach to recycling equipment—one that positions filter presses as part of a broader environmental compliance strategy. "A filter press alone isn't enough to meet today's regulations," explains CEO Lena Schmid. "Recyclers need to address air pollution, water pollution, and waste disposal as a system." To that end, Alps Clean Tech offers turnkey packages that include filter press equipment, air pollution control system equipment (like scrubbers and baghouses), and effluent treatment machine equipment. The company's EcoSphere line, for example, combines a filter press with a multi-stage water treatment system to remove heavy metals and toxins from wastewater, ensuring it meets EU discharge limits. "We recently worked with a lithium battery recycler in France that needed to reduce its nickel and cobalt emissions by 90%," Schmid recalls. "By integrating our filter press with a reverse osmosis unit and activated carbon filters, they not only complied but also recovered 15% more lithium from their waste stream." Alps Clean Tech's focus on regulatory expertise has made it a trusted partner for recyclers operating in strict jurisdictions like California and Japan.

Vaduz Recycling Innovations (VRI) specializes in a niche but vital area: plastic recycling and conveying systems. The company's filter presses are engineered to handle the sticky, low-density byproducts of plastic processing, such as the wastewater from PET bottle washing or the sludge from plastic pellet production. "Plastic recycling generates a lot of fine particles and emulsified oils, which standard filter presses struggle to separate," says VRI's product manager, Jan Keller. The company's PlasticPress-1500 solves this with a unique membrane design that uses air pressure to squeeze out excess moisture, leaving behind a dry cake that can be incinerated or repurposed as fuel. VRI also integrates its filter presses with plastic pneumatic conveying system equipment, allowing recyclers to transport the dewatered cake directly to storage or processing. For clients looking to reduce plastic waste further, the company offers hydraulic briquetter equipment that compresses the dry cake into dense blocks for easier handling. "Our goal is to make plastic recycling as efficient and profitable as possible," Keller adds. "A good filter press turns waste into a resource, not a liability."

Not all filter press suppliers focus on manufacturing—some excel at connecting global buyers with the right equipment, and Sargans Industrial Traders (SIT) is Liechtenstein's premier wholesaler in this space. Founded in 1990, SIT sources filter presses from top European manufacturers (including some on this list) and distributes them to clients in over 50 countries, alongside auxiliary equipment like pumps, valves, and spare parts. "Many small to mid-sized recyclers don't have the bandwidth to design a custom filter press system from scratch," explains SIT's export manager, Karl Weber. "We simplify the process by offering pre-configured packages based on industry—whether it's a small wet process equipment setup for a local scrapyard or a large dry process system for an electronics recycler." SIT's strength lies in its inventory: the company stocks over 200 filter presses at its warehouse in Sargans, ensuring quick delivery for urgent orders. It also provides after-sales support, including technician training and maintenance contracts. "Our clients value reliability," Weber says. "When a filter press breaks down, downtime costs money. We make sure they have the parts and expertise to get back up and running fast."

Triesen Green Machines (TGM) caters to a often-overlooked segment: small-scale recyclers, community facilities, and on-site waste handlers. The company's claim to fame is its line of portable filter presses, which are lightweight, easy to operate, and designed for low-volume applications like restaurant grease traps, small-scale battery recycling, or lamp recycling. "Not every recycler needs a massive, industrial filter press," says TGM's founder, Heidi Meier. "A local auto shop recycling used oil filters, for example, needs something compact and affordable." TGM's MiniPress-500 fits the bill: weighing just 300 kg and requiring only a standard 220V power supply, it can process up to 500 liters of wastewater per day. The company also pairs its filter presses with specialized equipment like the bulb eater equipment, a handheld tool for safely crushing and recycling fluorescent lamps. "Our portable filter presses have been a game-changer for rural communities in Africa and South America," Meier adds. "They allow local recyclers to treat waste on-site, reducing the need to transport hazardous materials long distances."

Balzers Environmental Technologies (BET) specializes in high-temperature filter presses for metal melting and smelting operations—an area where standard presses often fail due to heat and corrosion. The company's MetaFilter line is built with heat-resistant materials like ceramic plates and titanium frames, making it ideal for use with metal melting furnace equipment or medium frequency electricity furnace equipment. "When you're melting lead, copper, or aluminum, the slag and dross generated are extremely hot and abrasive," says BET's technical engineer, Lisa Graf. "Our filter presses can handle temperatures up to 200°C, ensuring continuous operation even in harsh foundry environments." BET's presses are also designed to recover valuable metals from the slag, which can contain up to 10% residual metal. "A client in Turkey recently reported recovering an extra 2 tons of copper per month using our MetaFilter-800," Graf notes. Beyond filter presses, BET offers air pollution control system equipment to capture fumes from melting processes, making it a favorite among metal recyclers aiming to reduce their carbon footprint.

Rounding out our list is Eschen Precision Systems (EPS), a specialist in filter presses for electronic waste (e-waste) recycling—specifically, hard-to-process items like CRT monitors, lamps, and small batteries. E-waste contains a cocktail of toxins, including leaded glass (from CRTs), mercury (from lamps), and cadmium (from old batteries), making filter press design critical for safety. "CRT recycling, for example, generates leaded glass fines that can leach into water if not properly separated," explains EPS's R&D head, Dr. Elise Steiner. The company's CRT-Filter 2000 uses a combination of vacuum filtration and pressure pressing to capture 99.9% of lead particles, while its LampPress-300 is optimized for mercury-contaminated sludge from bulb recycling. EPS also offers a compact granulator with dry separator equipment, which works alongside its filter presses to recover valuable metals from e-waste. "Our mission is to make e-waste recycling safer and more profitable," Steiner says. "Every filter press we build is tested with actual e-waste samples to ensure it meets the strictest safety standards." With global e-waste projected to reach 74 million tons by 2030, EPS's niche expertise is more valuable than ever.
