Top 5 Suppliers of Compact Granulators with Dry Separators in Japan [2025]
Let's talk about recycling equipment that's quietly revolutionizing how we handle waste. Compact granulators with dry separators might not sound like the most exciting topic, but here's why they matter: they turn scrap—whether it's old circuit boards, plastic waste, or metal shavings—into clean, reusable materials, and they do it without guzzling water (unlike messy wet processes). In a world where sustainability isn't just a buzzword but a business necessity, these machines are the unsung heroes of recycling plants, big and small. And when it comes to precision engineering and eco-friendly tech, Japan has long been a front-runner. Today, we're diving into the top 5 suppliers in Japan that are leading the charge with these game-changing machines. Whether you're running a small workshop or a large-scale recycling facility, there's something here for everyone. Let's get started!
1. EcoRecycle Tech Japan
If you've ever wished for a recycling machine that's as efficient as it is space-saving, EcoRecycle Tech Japan might just be your new favorite supplier. Founded in 2008, this Tokyo-based company has made a name for itself by focusing on "small footprint, big impact" equipment—and their
compact granulator with dry separator
line is a perfect example. What sets them apart? They've skipped the traditional wet separation methods entirely, leaning into
dry process equipment
that uses air flow and electrostatic sorting to separate materials. No water tanks, no sludge, no wasted resources—just clean, dry separation that cuts operating costs by up to 25% (according to their customer case studies).
- Model EG-DS800: Their bestseller, handling 500–800 kg/hour with 95%+ separation efficiency for plastics and non-ferrous metals
- Ultra-compact design: At just 3.2m x 1.8m, it fits in workshops where space is tight (no need for a dedicated warehouse corner!)
- Energy-efficient motor: Uses 15% less power than comparable models, a hit with factories aiming for carbon neutrality
- User-friendly interface: A touchscreen panel that lets operators adjust settings with a few taps—no need for a tech degree to run it
One of their standout clients? A Osaka-based electronics recycler that switched to the EG-DS800 last year. They reported a 30% boost in daily throughput and a 40% ｄｒｏｐ in water bills (since they ditched their old wet separator). "It's like having a mini recycling plant in one machine," the plant manager told us—high praise for a company that prides itself on making advanced tech accessible.
2. Nippon Green Machinery Co., Ltd.
Nippon Green Machinery isn't just about granulators—they're about creating full-circle recycling solutions. Based in Nagoya, this 40-year-old company has deep roots in
circuit board recycling equipment
, and they've leveraged that expertise to build granulators that excel at processing e-waste. Their star product? The GC-DS500, a compact granulator with a built-in dry separator that's specifically designed for shredding and sorting circuit boards. Why circuit boards? They're notoriously tricky to recycle, with a mix of metals (copper, gold, silver), plastics, and fiberglass. Nippon Green's machine grinds them into uniform granules, then uses a combination of air classification and magnetic separation to pull out the valuable metals—all in one seamless step.
- Model GC-DS500: Optimized for circuit boards, achieving 98% purity for copper separation (a big deal for recyclers selling to smelters)
- Quiet operation: At 75 dB, it's quieter than most office printers—no need for ear protection during shifts
- Modular add-ons: Pair it with their plastic pneumatic conveying system to automatically move sorted plastics to storage, cutting down on manual labor
- Durable blades: Made from high-carbon steel, they last 3x longer than standard blades, reducing maintenance downtime
A major electronics recycler in Kyoto recently expanded its circuit board processing line with 10 of these machines, and they're raving about the results: "We used to send circuit boards to an external processor, but now we're recycling them in-house and turning a profit on the metals we recover. The GC-DS500 paid for itself in under a year!" For anyone in e-waste recycling, Nippon Green is a name to remember.
3. Tokyo Recycling Solutions
Tokyo Recycling Solutions (TRS) is all about "recycling made simple"—and their take on compact granulators with dry separators reflects that philosophy. Founded in 2012 by a team of engineers who'd previously worked in automotive manufacturing, TRS knows a thing or two about building machines that are tough, reliable, and easy to maintain. Their flagship model, the TRS-DryGran 1000, is unique because it integrates a
hydraulic briquetter
right into the system. Here's how it works: first, the granulator shreds the waste, then the dry separator sorts it into clean materials, and finally, the hydraulic briquetter compresses those materials into dense, stackable briquettes. No more loose granules spilling during transport—just neat, uniform blocks ready for sale or further processing.
- Model TRS-DryGran 1000: Handles 800–1000 kg/hour, with a built-in briquetter that compresses materials into 5kg or 10kg blocks
- All-in-one design: Saves space by combining three steps (granulating, separating, briquetting) into one machine
- Low maintenance: A self-cleaning separator screen that reduces clogs, and blades that can be replaced in under 30 minutes
- Versatile: Works with everything from aluminum shavings to plastic scraps—no need to buy separate machines for different materials
A metal recycling yard in Yokohama recently added two TRS-DryGran 1000s to its operation, and the owner had this to say: "Before, we'd granulate, separate, then manually load material into a separate briquetter. Now it's all done in one go, and we've cut labor costs by 40%. Plus, the briquettes are so uniform that smelters are paying us a premium for them!" For recyclers who want to streamline their workflow, TRS delivers.
4. Osaka Precision Systems
If "precision" is your top priority, Osaka Precision Systems (OPS) should be on your shortlist. This Osaka-based supplier has built its reputation on machines that deliver consistent, repeatable results—and their compact granulator with dry separator is no exception. What makes OPS stand out? They've borrowed technology from the semiconductor industry to create a dry separation system that's eerily accurate. Using high-speed cameras and AI-driven sensors, their machines can identify and sort materials with 99.2% precision—even tiny particles of metal or plastic that other separators might miss. It's overkill for some, but for industries where material purity is non-negotiable (like medical plastic recycling or high-grade metal recovery), it's a game-changer.
- Model OPS-PrecisionDS: 500–1200 kg/hour capacity, with AI-powered optical sorting for ultra-high purity (ideal for medical or food-grade plastic recycling)
- Smart diagnostics: The machine self-monitors for wear and tear, sending alerts to your phone when parts need replacing
- Customizable sorting: Adjust settings to target specific materials (e.g., "only separate ABS plastic from PC plastic" or "prioritize copper over aluminum")
- Energy recovery: Captures excess heat from the motor and uses it to warm the separation chamber, improving air flow efficiency in cold climates
A pharmaceutical packaging recycler in Hokkaido switched to OPS machines last year, and their quality control manager explained: "We can't have even a trace of the wrong plastic in our recycled resin, because it goes into making new pill bottles. The OPS-PrecisionDS sorts with such accuracy that our reject rate dropped from 8% to 0.5%. It's not just a machine—it's a quality control tool." For high-stakes recycling, OPS is worth the investment.
5. Hokkaido EcoEngineering
Last but never least, Hokkaido EcoEngineering (HEE) brings a unique perspective to the table: they focus on machines that work in harsh environments. Based in Sapporo, HEE originally designed equipment for mining and construction (think cold temperatures, dusty conditions), but they've adapted that ruggedness to recycling equipment. Their
compact granulator with dry separator
line is built to withstand the kind of wear and tear that would break a standard machine—making them a favorite among recycling plants that process tough materials like scrap metal, glass, or even small electronic appliances. And yes, they still prioritize efficiency: their dry separation uses a combination of magnetic sorting and air classification, but with reinforced components that can handle debris without jamming.
- Model HEE-ToughGran: 600–1500 kg/hour, built with reinforced steel frames and dust-resistant motors (perfect for outdoor or semi-outdoor setups)
- Low-temperature operation: Works reliably in temperatures as low as -15°C, a must for Hokkaido and northern Japan
- Easy to clean: A quick-disassemble design lets operators hose down the granulator chamber in minutes (no more scrubbing stuck-on debris!)
- Multi-material processing: Shreds and sorts everything from aluminum cans to small motor parts without needing to reconfigure the machine
A scrap metal yard in Akita has been using HEE-ToughGran machines for three winters now, and the owner laughs when he talks about them: "We left one outside during a snowstorm last year—big mistake, right? But when we fired it up the next day, it ran like nothing happened. These things are built like tanks." For recyclers in tough climates or those processing heavy-duty materials, HEE is the supplier that won't let you down.
