Their flagship product, the lead acid battery breaking and separation system , is a marvel of engineering, combining a robust hydraulic cutter for initial battery disassembly with a precision separation unit that splits lead grids, plastic casings, and sulfuric acid with minimal manual intervention. What sets KERT apart is their obsession with efficiency: their latest model processes 2,000 kg of batteries per hour while consuming 30% less energy than competitors. Beyond equipment, they offer on-site training for operators, ensuring clients maximize throughput while adhering to safety protocols. "We don't just sell machines—we build partnerships," says CEO Min-Jun Park. "Our clients range from small scrap yards to multinational recycling plants, and we tailor every system to their workflow, whether they need a compact unit for urban settings or a mega-plant for industrial-scale operations."
2. Hanwha Recycling Solutions
A subsidiary of the Hanwha Group, Hanwha Recycling Solutions brings the conglomerate's legacy of innovation to the recycling sector, with a focus on ULAB breaking and separating equipment (ULAB, or "Used Lead-Acid Battery," is the industry term for scrap batteries). Their ULAB-specific line is designed to handle the variability in battery sizes and conditions, from car batteries to large industrial units. The equipment uses a two-step process: first, a gentle pre-shredder to crack casings without damaging lead grids, then a magnetic and air separation system to isolate lead fragments from plastic. What impresses clients most is Hanwha's commitment to sustainability—their systems reuse 90% of the water in their wet separation processes, and their plastic pneumatic conveying system equipment ensures no microplastics escape into the environment. "We started as a plastics recycler," notes sustainability director Ji-Hyun Kim, "so we understand the importance of keeping every material in the loop. Our ULAB equipment doesn't just recover lead; it turns plastic casings into high-quality pellets for new battery production."
3. GreenMech Engineering
While many suppliers focus solely on mechanical separation, GreenMech Engineering has made its mark by integrating air pollution control system equipment into every recycling line. Lead-acid battery recycling releases particulates and acid fumes, which can harm workers and violate environmental laws. GreenMech's solution? A three-stage filtration system: first, a cyclone separator to catch large dust particles, then a wet scrubber for acid mist, and finally a HEPA filter for ultrafine particulates. "In Korea, the fine dust regulations are some of the strictest in the world," explains sales manager Tae-Woo Lee. "Our clients can't afford downtime due to emissions violations, so we built our systems to not just meet but exceed standards. For example, our air pollution control machines reduce lead particulate emissions to 0.01 mg/m³—10 times lower than the legal limit." Beyond pollution control, GreenMech offers turnkey projects, including installation and ongoing maintenance, making them a favorite for first-time recyclers nervous about navigating complex regulations.
4. Daewoo Environmental Technologies
Daewoo is synonymous with heavy industry, and their foray into recycling equipment reflects that heritage—their systems are built for volume. Their flagship setup pairs a 4-shaft shredder equipment with advanced dry process equipment , capable of processing 5 tons of lead-acid batteries per hour. The 4-shaft design ensures even shredding, preventing jams and reducing wear on blades, while the dry separation unit uses electrostatic and density-based sorting to separate lead, plastic, and debris. What truly distinguishes Daewoo is their use of AI: cameras and sensors scan materials in real time, adjusting separator settings to maintain 99.8% purity. "We work with large recycling yards that process thousands of batteries daily," says chief engineer Seung-Ho Park. "They can't afford inefficiencies, so we built a system that learns from each batch. If a shipment has more plastic-heavy batteries, the AI tweaks the air flow and magnetic strength to keep separation sharp. It's like having a master operator on duty 24/7."
5. Seoul Battery Recycling Systems
Not every recycler needs a mega-plant, and Seoul Battery Recycling Systems caters to small and medium-sized operations with their compact granulator with dry separator equipment . Designed to fit in spaces as small as 50 square meters, this modular system can process 500–1,000 kg per hour, making it ideal for auto repair shops, small scrap dealers, or regional recycling cooperatives. The granulator uses a low-speed, high-torque motor to minimize noise (under 75 dB) and energy use, while the dry separator—small enough to fit through a standard door—uses vibration and air flow to separate materials. "We started this line after visiting rural recyclers who told us big systems were too expensive and took up too much space," says founder Mi-Sun Kim. "Our compact unit costs 60% less than industrial models and can be installed in a weekend. And because it's modular, clients can add a second granulator later if their business grows."
6. K-Tech Sustainable Solutions
K-Tech has carved a niche in wet process equipment , a method particularly effective for recovering sulfuric acid—a valuable byproduct often overlooked in dry systems. Their process starts with a hydraulic cutter to open batteries, then submerges components in a neutralizing solution that dissolves acid, which is later purified and sold to chemical manufacturers. The remaining lead and plastic are separated using water-based density sorting, and their effluent treatment machine equipment ensures no contaminated water is released. "Acid recovery is a game-changer for profitability," explains technical director Ho-Jin Lee. "A medium-sized plant can recover 500 liters of sulfuric acid per day, which sells for $0.50–$1 per liter. That turns a cost center into a revenue stream. Plus, our effluent treatment machine uses reverse osmosis to recycle 95% of the water, so clients save on utility bills too."
7. LG Eco-Systems
As the world shifts to lithium-ion batteries, LG Eco-Systems has future-proofed its offerings by designing systems that handle both lead-acid and Li-ion battery breaking and separating equipment . Their dual-purpose line uses adjustable shredders and sorting algorithms to switch between battery types in under an hour, eliminating the need for separate facilities. For lead-acid batteries, the system relies on mechanical separation and acid neutralization; for lithium-ion, it adds a thermal treatment step to safely handle flammable electrolytes. "Our clients told us they didn't want to invest in equipment that would become obsolete as EVs grow," says product manager Soo-Jin Park. "By combining lead-acid and Li-ion processing, we're giving them a 10-year+ roadmap. It's not just about today's recycling needs—it's about tomorrow's."
8. Pohang Heavy Industries
Pohang Heavy Industries is known for building equipment that lasts, and their lead-acid recycling line is no exception. Their hydraulic cutter equipment and 2-shaft shredder equipment are constructed with reinforced chromium steel blades and heavy-duty hydraulic rams, designed to withstand 10+ years of daily use. The hydraulic cutter excels at breaking down tough battery casings, while the 2-shaft shredder reduces materials to uniform particles for easier separation. "We test our equipment to failure in the lab, then build in 30% extra durability," says quality control head Kang-Min Lee. "A recycler in Busan has been using our first 2-shaft shredder for 12 years, and it still processes 800 kg per hour. That's the Pohang promise—we don't just sell machines; we build partners for the long haul."
9. Incheon Recycling Machinery
Incheon Recycling Machinery focuses on the "invisible" part of recycling: material handling. Their plastic pneumatic conveying system equipment is a hit with large plants, as it automates the transport of plastic fragments from separation units to storage or processing areas. Using high-pressure air, the system moves plastic pellets through tubes at speeds up to 20 m/s, eliminating the need for manual labor or conveyor belts. "We visited a client who had 10 workers shoveling plastic into bins—inefficient and risky for back injuries," recalls operations director Hyeon-Ju Kim. "Our pneumatic system cut their labor costs by 70% and reduced plastic waste by 15%, since nothing gets spilled on the floor. It's a small part of the recycling line, but it makes a big difference in daily operations."
s10. Kyunggi Environmental Systems
For recyclers navigating strict environmental regulations, Kyunggi Environmental Systems offers peace of mind with their integrated compliance packages. Alongside standard breaking and separation equipment, they include air pollution control machines equipment and water process equipment , ensuring clients meet Korean EPA, EU REACH, and even California's strict Proposition 65 standards. Their air systems use activated carbon filters and UV scrubbers to neutralize fumes, while their water treatment units remove heavy metals and acids, producing water clean enough for reuse in the plant. "Regulatory fines can shut down a recycling business overnight," says compliance officer Min-Soo Park. "We take the guesswork out by pre-certifying our systems with all major environmental bodies. Clients get a turnkey solution where every component works together to keep them compliant, so they can focus on recycling, not paperwork."
