Top 10 Desulfurizer Suppliers, Manufacturers, Wholesalers and Traders in Dominican Republic

Nestled in Santo Domingo's industrial zone, Caribbean Eco-Recycling Solutions (CER) has been a trusted name in the Dominican recycling scene since 2010. What started as a small trading outfit has grown into a full-fledged manufacturer, with a focus on lead acid battery recycling equipment—a sector where desulfurization is non-negotiable. "We saw early on that many local recyclers were struggling with outdated equipment that either didn't meet emissions standards or broke down constantly," says Maria Alvarez, CER's operations director. "Our mission became to build reliable, affordable machines that make compliance feel manageable, not impossible."

CER's star product? Their de-sulfurization machines equipment , designed specifically for lead acid battery breaking and separation systems. These units use a chemical-neutralization process to strip sulfur from battery paste, turning it into calcium sulfate—a safe, reusable byproduct. "Our clients love that it's low-maintenance," Alvarez adds. "A small team can operate it with minimal training, and it integrates seamlessly with our lead acid battery breaking and separating plant setups. We've even helped a family-run recycler in La Vega triple their output while cutting emissions by 40%."

Beyond desulfurization, CER also offers air pollution control machines equipment to complement their systems, ensuring that every step of the recycling process—from shredding to melting—stays clean. What sets them apart? Their 24/7 technical support. "Recycling plants can't afford downtime," Alvarez explains. "If a machine breaks at 2 a.m., our team is on the phone or on-site within hours. That's the Caribbean difference."

When it comes to lithium-ion battery recycling—a fast-growing sector in the Dominican Republic—Dominican Green Tech Industries (DGTI) leads the pack. Based in Santiago, DGTI recognized the demand for specialized equipment as electric vehicles and portable electronics became more common on the island. "Lithium batteries are trickier than lead acid—they're volatile, and their byproducts require precise handling," says Juan Mendez, DGTI's founder. "Our li battery recycling equipment is built to tackle that complexity, and desulfurization is a key part of that puzzle."

DGTI's li-ion battery breaking and separating equipment uses a dry process to shred batteries and separate metals, plastics, and electrolytes. But it's their integrated air pollution control system equipment that truly shines. "Lithium recycling releases sulfur dioxide and other gases," Mendez notes. "Our desulfurization units scrub these emissions before they leave the plant, using a water-based filtration system that's both effective and energy-efficient. A client in Punta Cana recently told us their neighbors no longer complain about odors—now that's a win."

What makes DGTI stand out? Their commitment to innovation. They recently launched a mobile desulfurization unit for small-scale recyclers who can't afford a fixed setup. "Not everyone has the space or budget for a full plant," Mendez says. "This unit fits in a truck, connects to existing equipment, and still meets national emissions standards. It's our way of making sustainability accessible to everyone."

Santo Domingo Recycling Systems (SDRS) prides itself on being a "one-stop shop" for recyclers, and their product lineup reflects that ambition. From circuit board recycling equipment to dry process equipment , SDRS covers nearly every niche—but their desulfurization offerings are what keep clients coming back. "Circuit boards contain sulfur-based flame retardants, and when you shred them, those compounds can become airborne," explains Carlos Rojas, SDRS's technical advisor. "Our desulfurization systems trap those particles before they escape, protecting both workers and the environment."

SDRS's circuit board recycling plant wcbd-2000a with dry separator (500-2000kg/hour capacity) is a fan favorite, and it's often paired with their compact desulfurization module. "The module uses activated carbon filters to sulfur compounds, and it's easy to swap out the filters—no special tools needed," Rojas says. "A tech school in Santo Domingo even uses our smaller units for their vocational training program. It's rewarding to see the next generation of recyclers learn on equipment that's actually used in the field."

Beyond equipment, SDRS offers training workshops for plant operators, ensuring that clients get the most out of their desulfurization systems. "We don't just sell machines—we build partnerships," Rojas adds. "If a client is struggling with a process, we send a team to audit their workflow and suggest tweaks. That's why 80% of our business comes from repeat customers."

Hispaniola Environmental Machinery (HEM) takes a holistic approach to recycling, focusing on systems that work together seamlessly. Based in San Pedro de Macorís, HEM specializes in cable recycling equipment and hydraulic press machines equipment , but their desulfurization units are the glue that holds many of their setups together. "Cable recycling involves melting plastic and metal, which can release sulfur fumes," says Linares Fernandez, HEM's sales manager. "Our desulfurization machines act as a safety net, ensuring that even if something goes wrong in the melting process, emissions stay within legal limits."

HEM's scrap cable stripper equipment is designed to remove plastic insulation from wires, but when paired with their air pollution control machines equipment (which includes desulfurization), it becomes a closed-loop system. "We had a client in Barahona who was fined for excessive emissions before switching to our setup," Fernandez recalls. "Within three months, their emissions were 90% lower, and they're now one of the government's 'model recyclers.' That's the impact we strive for."

What makes HEM unique? Their focus on durability. "Our machines are built to withstand the Caribbean heat and humidity," Fernandez says. "We use stainless steel components and corrosion-resistant coatings, so even after years of use, the desulfurization units perform like new. For recyclers operating on tight margins, that reliability is everything."

Punta Cana Sustainable Technologies (PCST) may be best known for their lamp recycling equipment and bulb eater equipment (a nifty machine that crushes fluorescent bulbs to recover mercury), but their desulfurization offerings are quietly making waves in the metal recycling sector. "Metal melting furnaces—like our medium frequency electricity furnace equipment —release sulfur dioxide when scrap metal is heated," explains PCST's founder, Roberto Torres. "Desulfurization isn't just about compliance here; it's about protecting the furnace itself. Sulfur can corrode the lining, leading to costly repairs. Our units extend furnace life by up to 50%."

PCST's desulfurization systems use a lime-based injection process to neutralize sulfur gases, turning them into solid calcium sulfite. "It's a simple, effective method, and the byproduct can be sold to construction companies for use in cement," Torres adds. "A metal recycler in Bavaro told us they now make an extra $2000 a month from selling that byproduct. That's sustainability with a side of profit."

PCST also offers on-site testing for clients unsure of their sulfur emissions. "Many recyclers don't realize how much sulfur they're releasing until they get a fine," Torres says. "We bring in portable monitors, run tests for a week, and then recommend the right desulfurization setup. It's a free service, and it helps us build trust."

La Romana Recycling Innovations (LRRI) has carved a niche in motor recycling machines equipment and motor stator cutter equipment , but their desulfurization expertise spans multiple sectors. "Motors contain copper windings and steel cores, but when you shred them, the insulation materials—often sulfur-based—can create toxic dust," says Elena Marquez, LRRI's product developer. "Our desulfurization systems use wet scrubbers to capture that dust, turning it into a slurry that can be safely disposed of or repurposed."

LRRI's lead refinery furnace setups (used in lead acid battery recycling) are another area where desulfurization takes center stage. "Refining lead involves high temperatures, and without proper desulfurization, you're looking at heavy emissions," Marquez notes. "Our units are designed to handle the heat, with refractory linings that withstand temperatures up to 1200°C. We recently supplied a refinery in San Cristóbal that now meets EU emissions standards—something they never thought possible."

What sets LRRI apart? Their customization options. "No two recycling plants are the same," Marquez says. "A small motor recycler in Monte Plata needs a different desulfurization setup than a large lead refinery in Santo Domingo. We design each system to fit the client's space, budget, and output goals. It takes longer, but the results speak for themselves."

San Pedro Eco-Equipment (SPE) focuses on the often-overlooked world of refrigerator & AC recycling machines equipment , and their desulfurization systems play a critical role in that niche. "Refrigerators and AC units contain refrigerants, oils, and plastics—many of which release sulfur compounds when shredded," explains David Pena, SPE's sales director. "Our refrigerant extraction machine l refrigerant recycling machine sd-680 removes harmful gases, but the real work happens in the shredding phase. That's where our desulfurization units kick in."

SPE's desulfurization systems for refrigerator recycling use a two-stage process: first, a cyclone separator to catch large sulfur particles, then a wet scrubber for finer dust. "It's overkill for some, but we believe in going above and beyond," Pena says. "A hotel chain in Punta Cana recently started recycling their old AC units with our equipment, and they've been able to market themselves as 'zero-emission recyclers'—a big plus for eco-conscious travelers."

SPE also offers auxiliary equipment like conveyors and sorting tables, making it easy for clients to build a complete recycling line. "We want to take the stress out of setup," Pena adds. "From delivery to installation to training, we're with the client every step of the way. Desulfurization might not be the most glamorous part of recycling, but it's the part that lets businesses sleep at night."

Cibao Recycling Technologies (CRT), based in Moca, has made a name for itself with wet process equipment and water process equipment —and their desulfurization systems are designed to work hand-in-hand with these setups. "Wet processes use water to separate materials, but that water can become contaminated with sulfur compounds," says Ramon Diaz, CRT's chief engineer. "Our desulfurization units treat the water before it's reused or discharged, ensuring it meets Dominican water quality standards."

CRT's filter press to collect the paste of ulab (used in lead acid battery recycling) is often paired with their water-based desulfurization system. "The filter press separates lead paste from water, but the water still has sulfur residues," Diaz explains. "Our unit uses lime to precipitate the sulfur, turning it into a sludge that's easy to remove. A recycler in Santiago told us their water bills dropped by 30% after installing it, since they can now reuse the treated water."

What makes CRT unique? Their focus on energy efficiency. "Many desulfurization systems are power-hungry," Diaz notes. "Ours use variable-speed pumps and solar-powered controls, cutting energy use by up to 25%. For rural recyclers with unreliable electricity, that's a game-changer."

Barahona Green Machines (BGM) specializes in hydraulic briquetter equipment , hydraulic baler equipment , and other machines that compress recyclables into dense blocks for transport. But their desulfurization systems are a hidden gem, especially for plastic recyclers. "Plastic pneumatic conveying systems can stir up sulfur-rich dust from recycled plastics," says Sofia Lozano, BGM's marketing manager. "Our desulfurization units use electrostatic precipitators to trap that dust, keeping it from escaping into the air."

BGM's plastic pneumatic conveying system equipment is often sold with their desulfurization add-on, and clients love the combination. "A plastic recycler in Barahona was struggling with dust complaints from nearby homes," Lozano recalls. "After installing our system, the dust levels dropped so much that the neighbors actually came by to thank them. That's the kind of impact we live for."

BGM also offers training courses for operators, covering everything from basic maintenance to troubleshooting desulfurization issues. "Knowledge is power," Lozano says. "If your team knows how to spot a filter that needs changing or a pump that's about to fail, you avoid downtime. We even certify graduates, which looks great on their resumes. It's our way of investing in the industry's future."

Rounding out our list is Azua Environmental Systems (AES), a company that prides itself on "complete recycling solutions." From li-ion battery breaking and separating equipment (500-2500kg/hour capacity) to air pollution control system for li battery recycling plant , AES does it all—and their desulfurization systems are the backbone of their offerings. "We don't just sell a machine; we design a process," says Hector Guzman, AES's CEO. "Desulfurization isn't an afterthought here—it's integrated into every step, from pre-shredding to final processing."

AES's rotary furnace for paste reduction (used in lead acid battery recycling) is a prime example. The furnace melts lead paste, and as sulfur gases rise, they're immediately channeled into a desulfurization unit that uses ammonia-based scrubbing. "This process is 99% effective at removing sulfur dioxide," Guzman says. "We recently completed a project for a large recycling facility in Santo Domingo, and their emissions are now lower than the EU's strictest standards. That's a big deal for a country that's trying to attract green investment."

What makes AES stand out? Their global partnerships. "We work with German and Chinese manufacturers to source the best components, then assemble everything locally," Guzman explains. "That means our desulfurization systems have the quality of imported equipment but the price tag of a Dominican-made product. It's the best of both worlds."
