Top 10 Plastic pneumatic conveying system Suppliers, Manufacturers, Wholesalers and Traders in Sao Tome and Principe

Tucked away in the industrial zone of São Tomé City, EcoFlow Recyclers Ltd. has been a cornerstone of the local recycling scene since 2010. What started as a small workshop repairing old shredders has grown into a full-service supplier, and their claim to fame? A plastic pneumatic conveying system that's become the gold standard for efficiency in the region.

"We built our first pneumatic system for a client who was struggling to move lightweight plastic pellets across their factory floor," says Maria Almeida, EcoFlow's lead engineer. "The humidity here can gum up machinery, so we added corrosion-resistant components and adjustable air pressure settings. Now, that system runs 12-hour shifts without a hitch."

Beyond conveying systems, EcoFlow has expanded into air pollution control system equipment, recognizing that recycling shouldn't come at the cost of clean air. Their latest model, the EcoClean 3000, uses a multi-stage filtration process to capture dust and fumes, making it a favorite among battery recycling plants. They also offer hydraulic briquetter equipment, which compresses metal scraps into dense blocks for easier transport—perfect for small-scale scrap yards looking to maximize storage space.

What sets EcoFlow apart? Their "Island-Proof" guarantee. Every piece of equipment is tested under São Tomé's high humidity and temperature conditions, ensuring it lasts longer than imported alternatives. "We don't just sell machines," Maria adds. "We build partnerships. If a client calls with a problem at 6 a.m., we're there by 7."

When João Santos founded GreenLink Technologies in 2015, he saw a gap: while larger African nations had access to cutting-edge recycling tech, Sao Tome and Principe was stuck with outdated, inefficient equipment. Today, GreenLink is bridging that gap, with a focus on li-ion battery breaking and separating equipment—critical as the country sees a surge in discarded smartphones and laptops.

"Lithium-ion batteries are tricky," João explains. "If you don't separate the components properly, you risk fires or toxic leaks. Our breaking system uses a low-speed, precision cutter to split casings without damaging the valuable metals inside, then a magnetic separator to pull out cobalt and nickel."

But GreenLink hasn't forgotten the basics. Their plastic pneumatic conveying system, the GreenFlow 500, is designed for modularity—so clients can start small and scale up as their business grows. "A lot of our clients are family-owned operations," João notes. "They might start with a single conveying line, then add a second when they take on more circuit board recycling work. We make sure the systems integrate seamlessly."

The company also prides itself on training. Every purchase includes a two-day workshop where GreenLink's technicians teach clients how to maintain and repair equipment, reducing downtime and reliance on expensive overseas service calls. "Last month, a client in Príncipe called because their conveyor belt jammed," João laughs. "We walked them through fixing it over the phone. That's the GreenLink promise."

TechCycle Industries is the go-to for businesses serious about electronic waste. Based in Neves, a coastal town on São Tomé, they specialize in circuit board recycling equipment, but their plastic pneumatic conveying systems are the backbone of their operation.

"Circuit boards have so many tiny, valuable components—gold, silver, copper—but they're mixed with plastic and fiberglass," says Carlos Mendes, TechCycle's operations manager. "Our conveying system uses gentle air flow to transport shredded circuit boards to our separation line, ensuring even the smallest bits don't get lost in transit."

Their flagship circuit board recycling plant, the TechSep 2000, can process up to 500 kg per hour, and it's paired with an air pollution control system that meets European emission standards—no small feat in a country with limited regulatory oversight. "We believe in doing it right, even if it costs a little more," Carlos says. "Last year, we helped a client in Santo António get certified for exporting recycled metals to Europe, all because our pollution control system kept their emissions ultra-low."

TechCycle also offers custom solutions. When a local university needed a compact conveying system for their research lab, they designed a miniaturized version of their pneumatic line that fits in a 10x10 ft room. "We listen first, then build," Carlos adds. "That's how we've stayed relevant for 12 years."

IslandRecyclers Co. started as a scrap metal yard in 2008, but today, they're one of the few suppliers in São Tomé offering a full suite of recycling equipment—including a plastic pneumatic conveying system that's a hit with plastic bottle recycling plants.

"Bottles come in all shapes and sizes, and they're lightweight, which makes them hard to move with traditional conveyors," explains Ana Gomes, IslandRecyclers' sales director. "Our pneumatic system uses suction to pull bottles through a network of tubes, sorting them by color along the way. It's like a high-tech vacuum for recycling."

The company also excels in hydraulic equipment, with their hydraulic briquetter being a top seller for aluminum and copper scraps. "A local scrap dealer was storing loose copper wires in bags that kept tearing," Ana recalls. "We set them up with our briquetter, and now they're saving 30% on storage space. Plus, the briquettes fetch a better price at the foundry."

IslandRecyclers' secret? They source as many parts locally as possible, from metal casings to electrical wiring. "Importing parts can take months, and shipping costs are sky-high," Ana says. "By working with local machinists, we can repair equipment in days, not weeks. Our clients love that we're invested in the community's success."

PowerRecyclers International may have "international" in the name, but their roots are firmly in São Tome. Founded by a team of expat engineers who fell in love with the island, they've made a name for themselves with their li-ion battery breaking and separating equipment, which handles everything from phone batteries to electric vehicle packs.

"Lithium batteries are the future, but they're also a hazard if not recycled properly," says David Okonkwo, PowerRecyclers' technical director. "Our breaking system uses a water-cooled blade to prevent overheating, and the separating line uses eddy currents to extract lithium, cobalt, and graphite. It's safe, efficient, and designed to handle the high volumes we're seeing as electric bikes grow in popularity here."

To complement their battery equipment, PowerRecyclers offers a plastic pneumatic conveying system that moves battery casings and plastic components to their recycling line. "The casings are often made of high-quality plastic that can be repurposed," David notes. "Our system ensures they're transported without cracking, so they retain their value."

The company also runs a training program for young engineers, teaching them to maintain and repair recycling equipment. "We want to build local expertise," David says. "São Tome doesn't need to import technicians—we can grow our own."

CleanTech Solutions is all about precision. Located in the town of Trindade, they specialize in circuit board recycling equipment that extracts precious metals with pinpoint accuracy—and their plastic pneumatic conveying system is engineered to match that precision.

"Circuit boards have tiny gold pins and silver contacts that can get lost in transit," says Paula Sousa, CleanTech's founder. "Our conveying system uses variable air pressure to gently carry shredded boards, ensuring even the smallest particles reach the separation table. We've had clients tell us their metal recovery rate increased by 15% after switching to our system."

CleanTech also offers air pollution control system equipment tailored to circuit board recycling, which releases fewer toxins than traditional methods. "Burning circuit boards used to be common here, but it's terrible for the air," Paula says. "Our system captures 99% of the fumes, turning a harmful process into a clean one. It's not just good for business—it's good for our kids' lungs."

The company is also a pioneer in "dry process" recycling, which uses less water than wet systems—a critical advantage in a country where water resources are limited. "We designed our dry separation line to work with our pneumatic system, so we use 70% less water than traditional plants," Paula adds. "Sustainability isn't an afterthought here; it's how we do business."

As the name suggests, RapidFlow Conveyors is obsessed with speed—and their plastic pneumatic conveying system lives up to the hype. Designed for high-volume operations, their systems can move up to 2000 kg of plastic per hour, making them ideal for large-scale recycling plants.

"We built our first high-capacity system for a client in Ghana, but we quickly realized São Tomé needed it too," says Miguel Costa, RapidFlow's operations manager. "With tourism growing, the amount of plastic waste from hotels and resorts is skyrocketing. Our system ensures that waste is processed quickly, before it piles up."

RapidFlow also offers a range of accessories, from flexible tubing that bends around factory obstacles to sensors that detect blockages in real time. "A blockage can shut down an entire line," Miguel says. "Our sensors send alerts to a phone app, so operators can fix the problem before it becomes a crisis. We've had clients tell us the app alone saved them thousands in downtime."

Despite their focus on speed, RapidFlow hasn't sacrificed durability. Their systems are built with stainless steel components to withstand salt air in coastal areas. "We tested our first prototype on a beach in Praia das Conchas," Miguel laughs. "It got covered in salt spray for six months, and it still worked like new. That's the RapidFlow promise."

Sustainable Systems Ltd. is on a mission to make recycling accessible to small businesses—and their compact plastic pneumatic conveying system is a game-changer for startups. "Not everyone can afford a massive industrial system," says José Ferreira, Sustainable Systems' founder. "Our mini-conveyor fits in a 15x15 ft space and costs a fraction of the price, but it still moves 100 kg of plastic per hour. It's perfect for a family-run recycling shop."

The company also offers hydraulic briquetter equipment that's designed for ease of use. "Our briquetter has a simple control panel with just three buttons: start, stop, and compact," José says. "We've had clients who've never used machinery before learn to operate it in 10 minutes. No confusing manuals, no fancy degrees required."

Sustainable Systems' commitment to accessibility extends to financing. They offer payment plans with low monthly rates, allowing small businesses to invest in equipment without draining their savings. "A client once told me, 'I thought I'd never afford a conveyor,'" José recalls. "Now, they're processing twice as much waste and hiring two more employees. That's why we do this."

BatteryCycle Solutions is the go-to for all things battery recycling, from lead-acid car batteries to li-ion phone batteries. Their li-ion battery breaking and separating equipment is designed to handle the unique challenges of lithium chemistry, and their plastic pneumatic conveying system ensures battery casings are recycled, not wasted.

"Lithium batteries have plastic casings that are often made of polypropylene, which is highly recyclable," says Elisa Nunes, BatteryCycle's technical lead. "Our conveying system separates the casings from the battery cells, sending the plastic to a granulator and the cells to the breaking line. It's a closed-loop system—nothing goes to waste."

BatteryCycle also offers training on battery safety, a critical service in a country where many recyclers are unaware of the risks of lithium fires. "We host workshops where we teach people how to handle damaged batteries, how to store them safely, and how to use our equipment without accidents," Elisa says. "Last year, we trained over 200 recyclers. Knowledge is just as important as equipment."

The company is also working on a mobile recycling unit, which will travel to remote villages to collect and process batteries. "Not everyone can bring their batteries to a plant," Elisa adds. "We want to meet people where they are, making recycling accessible to every corner of the islands."

Rounding out our list is AllInOne Recyclers, a one-stop shop for recycling equipment. From plastic pneumatic conveying systems to hydraulic balers, they offer everything a recycling plant needs to get up and running—and their "StartSmart" package has helped dozens of new businesses launch.

"Starting a recycling business is overwhelming," says Francisco Lopes, AllInOne's founder. "You need a shredder, a conveyor, a separator, and pollution control equipment. Our StartSmart package includes a basic pneumatic conveying system, a small hydraulic briquetter, and a training session—all for a price that won't break the bank."

AllInOne's plastic pneumatic conveying system is designed to be compatible with equipment from other brands, making it easy to upgrade later. "We don't lock clients into our ecosystem," Francisco says. "If they want to add a better shredder from another supplier down the line, our conveyor will work with it. We want them to succeed, even if that means they buy from someone else someday."

The company also prides itself on after-sales support, with a 24/7 hotline for emergencies. "A client called at 2 a.m. once because their conveyor belt broke," Francisco laughs. "Our technician was there by 4 a.m., and they were back up and running by 6. That's the AllInOne promise: we're with you every step of the way."
