Transforming Scrap Cables into Valuable Resources with Advanced Recycling Solutions
Introduction: The Growing Need for Cable Recycling in Indonesia
In the heart of Southeast Asia, Indonesia stands at a crossroads of rapid development and environmental responsibility. As the country urbanizes and digitalizes, the demand for electrical cables—powering homes, offices, and industries—has surged. But with progress comes a hidden challenge: the mounting pile of scrap cables. Discarded power cords, communication lines, and industrial wiring, once vital to connectivity, now linger in landfills or informal dumps, leaking toxic plastics and metals into soil and water. For a nation rich in natural resources yet grappling with waste management issues, recycling these cables isn't just an environmental imperative—it's an economic opportunity.
Scrap cables are more than just trash. Inside their rubber or plastic sheaths lies copper, one of the most valuable non-ferrous metals, and high-quality plastics that can be repurposed. Yet, traditional recycling methods in Indonesia often fall short: manual stripping is labor-intensive and unsafe, while outdated machinery struggles to separate metals and plastics efficiently. This inefficiency means lost revenue for recyclers and missed chances to reduce reliance on virgin materials. Enter the WCD-1200S Granulator, a cutting-edge solution that's changing the game for cable recycling in Indonesia. In this case study, we explore how one local recycling facility partnered with a leading recycling machine supplier to overhaul its operations, turning scrap cables into a sustainable source of income—all while meeting strict environmental standards.

Project Background: A Local Recycler's Struggle with Outdated Equipment
PT. EcoRecycle Indonesia, a mid-sized recycling company based in West Java, had long been a player in the local waste management scene. Specializing in e-waste and metal recovery, the company faced a recurring frustration: its cable recycling line was underperforming. "We were drowning in scrap cables," recalls Mr. Agus Setiawan, the company's operations manager. "Every month, we collected tons of them—from construction sites, electronics repair shops, even old factories. But our setup couldn't keep up."
At the time, PT. EcoRecycle relied on basic scrap cable stripper equipment and manual labor. Workers used hand tools to strip plastic sheaths, a slow process that often damaged copper wires, reducing their value. What little automation they had—a decades-old cutter—frequently jammed, halting production for hours. "We were losing 30% of copper to breakage, and the plastic waste was piling up because we couldn't separate it cleanly," Agus explains. Worse, the facility struggled to meet Indonesia's tightening environmental regulations. Without proper air pollution control system equipment, plastic fumes from heating during stripping posed health risks to workers and drew complaints from nearby communities.
By 2023, PT. EcoRecycle knew it needed a upgrade. The goal was clear: boost throughput, improve metal recovery rates, ensure compliance with environmental laws, and reduce labor costs. After researching options across Asia, the company reached out to a trusted recycling machine supplier with a reputation for tailored solutions. "We didn't just need a machine," Agus emphasizes. "We needed a partner who understood Indonesia's unique challenges—our mix of cable types, our space constraints, and our commitment to sustainability."

Challenges: Navigating Indonesia's Unique Recycling Landscape
PT. EcoRecycle's journey wasn't without hurdles. Indonesia's cable recycling sector faces a set of challenges distinct from other countries, making a one-size-fits-all solution impossible. Here's what the team had to overcome:
1. Diverse Cable Types, Inconsistent Quality:
Scrap cables in Indonesia come in all shapes and sizes—from thin household wires to thick industrial cables, each with different combinations of copper, aluminum, rubber, and plastic (PVC, PE, or XLPE). "One day, we'd get a batch of flexible phone chargers; the next, rigid power cables from a demolished factory," Agus notes. "Our old scrap cable stripper equipment couldn't adjust, leading to uneven stripping and wasted material."
2. Tight Environmental Regulations: In 2022, Indonesia's Ministry of Environment introduced stricter emissions standards for recycling facilities, particularly targeting volatile organic compounds (VOCs) from plastic processing. Without air pollution control system equipment, PT. EcoRecycle risked fines or even shutdowns. "We couldn't afford to cut corners on (environmental protection)," Agus says. "Our community depends on us to keep the air clean."
3. Space and Infrastructure Limitations: Located in a dense industrial park, PT. EcoRecycle's facility had limited floor space. Any new equipment needed to be compact yet powerful. Additionally, the local power grid required machines that could operate on 380V three-phase electricity without causing disruptions.
4. Labor Efficiency: While Indonesia has a large workforce, manual cable stripping is physically demanding and low-paying, leading to high turnover. PT. EcoRecycle wanted to upskill its team, shifting from repetitive tasks to operating and maintaining advanced machinery.

The Solution: A Customized Cable Recycling System
After conducting on-site assessments and analyzing PT. EcoRecycle's needs, the recycling machine supplier proposed a comprehensive cable recycling system centered around the WCD-1200S Granulator. This wasn't just a single machine—it was an integrated workflow designed to address every challenge, combining:
"The supplier didn't just sell us equipment—they designed a process," Agus says. "They even adjusted the system to handle our most common cable types, like the jelly-filled cables used in telecommunications, which are notoriously sticky and hard to process."
- WCD-1200S Granulator: The core of the system, a high-capacity granulator built for efficient separation of metals and plastics.
- Scrap Cable Stripper Equipment: Upgraded pre-processing tools to remove outer sheaths before granulation, reducing wear on the granulator blades.
- Hydraulic Cutter Equipment: A rugged pre-chopper to cut long or thick cables into manageable pieces (5-10cm), ensuring smooth feeding into the granulator.
- Air Pollution Control System Equipment: A multi-stage filtration unit to capture dust and fumes, including activated carbon filters for VOCs.
- Plastic Pneumatic Conveying System Equipment: A network of pipes and blowers to transport separated plastic granules from the granulator to storage, saving floor space.
"The supplier didn't just sell us equipment—they designed a process," Agus says. "They even adjusted the system to handle our most common cable types, like the jelly-filled cables used in telecommunications, which are notoriously sticky and hard to process."
Implementation: From Installation to Training
In early 2024, the new system arrived at PT. EcoRecycle's facility. The installation team from the recycling machine supplier worked alongside local technicians to set up the equipment, ensuring it fit within the facility's tight layout. "They were meticulous," Agus recalls. "The hydraulic cutter equipment was placed near the loading dock for easy access, the granulator in the center, and the air pollution control system equipment near the exhaust vents. It was like solving a puzzle—and they made it look easy."
Training was another critical phase. Over two weeks, the supplier's engineers trained PT. EcoRecycle's 12-person team on every aspect of the system: operating the touchscreen controls of the WCD-1200S, maintaining the hydraulic cutter blades, replacing filters in the air pollution control system, and troubleshooting common issues. "Many of our workers had never used computers before," Agus laughs. "But the interface was so intuitive—with icons and simple instructions—that even our most senior technician, Pak Joko, picked it up in a day."
One key customization was the addition of a variable-speed drive on the granulator, allowing operators to adjust rotor speed based on cable type. "For thin wires, we slow it down to avoid over-grinding; for thick cables, we speed it up for better separation," explains Pak Joko, now the facility's lead technician. "It's like having a machine that thinks for itself."

Results: By the Numbers—A Transformation Story
Six months after commissioning, the results spoke for themselves. PT. EcoRecycle's cable recycling line had undergone a dramatic transformation, with metrics that exceeded even the supplier's projections.
"The numbers don't lie," Agus says, pointing to the table. "We're now processing four times more cables, and the copper we recover is 98% pure—good enough to sell directly to smelters. The plastic granules, too, are in high demand from local manufacturers making pipes and containers."
Beyond the metrics, the impact on the community has been profound. With the air pollution control system equipment in place, complaints from neighbors have stopped. "Kids used to cough when they walked past our facility," Agus notes. "Now, we even have parents asking about job openings—they see us as a responsible employer."
| Metric | Before (Old Equipment) | After (WCD-1200S System) | Improvement |
|---|---|---|---|
| Daily Throughput | 500 kg/day | 2,000 kg/day | +300% |
| Copper Recovery Rate | 75% | 98% | +23% |
| Plastic Recovery Rate | 60% | 95% | +35% |
| VOC Emissions | 150 mg/m³ (non-compliant) | 12 mg/m³ (well below limit) | -92% |
| Labor Cost per kg | IDR 5,000/kg | IDR 1,800/kg | -64% |

The Process Flow: How It All Works Together
To understand the system's success, let's walk through a typical day at PT. EcoRecycle's cable recycling line:
Step 1: Feeding and Pre-Cutting
– Scrap cables arrive at the facility and are sorted by type (e.g., power cables, data cables). Thick or long cables are first fed into the hydraulic cutter equipment, which slices them into 5-10cm chunks. "This prevents jams in the granulator and makes stripping easier," Pak Joko explains.
Step 2: Stripping
– The pre-cut cables move to the scrap cable stripper equipment, where rotating blades gently remove outer plastic or rubber sheaths. For tricky cables with multiple layers (like those with aluminum shielding), the stripper adjusts pressure to avoid damaging the inner copper wires.
Step 3: Granulation
– The stripped cables enter the WCD-1200S Granulator, where a high-speed rotor with hardened steel blades grinds them into small granules (3-5mm). As the granules exit the granulator, a magnetic separator pulls out ferrous metals (like steel reinforcements), leaving a mix of copper and plastic.
Step 4: Air Separation
– The copper-plastic mix is blown through an air classifier, which uses wind force to separate lighter plastic granules from heavier copper. "The plastic is so light it floats, while the copper sinks—like panning for gold," Agus jokes.
Step 5: Material Handling
– Separated plastic granules are sucked into the plastic pneumatic conveying system equipment, which transports them to a storage silo. Copper granules fall into a collection bin, ready for melting into ingots.
Step 6: Emission Control
– Throughout the process, fumes and dust are captured by hoods and ducted to the air pollution control system equipment. The air passes through a cyclone separator to remove large particles, then a HEPA filter for fine dust, and finally an activated carbon bed to trap VOCs. Clean air is released back into the atmosphere.
Environmental Impact: Closing the Loop on Cable Waste
For PT. EcoRecycle, the new system isn't just about profits—it's about contributing to Indonesia's circular economy goals. By recycling 2,000 kg of scrap cables daily, the facility recovers approximately 1,200 kg of copper and 700 kg of plastic each day. Over a year, that's 438 tons of copper and 255 tons of plastic kept out of landfills.
"Mining copper requires massive energy and leaves scars on the earth," Agus points out. "Recycling one ton of copper saves 15 tons of ore and 90% of the energy needed to mine new copper. For Indonesia, which imports much of its copper, this is a step toward self-reliance."
The plastic recycling also plays a role. Instead of incinerating or burying plastic sheaths, PT. EcoRecycle sells the granules to local manufacturers for use in products like cable insulation, pipes, and even furniture. "We're not just recycling—we're creating a local supply chain," Agus says proudly.

Testimonial: A Partner for the Long Run
"When we first considered upgrading, we worried about the cost. But looking back, it was the best investment we ever made. The WCD-1200S system paid for itself in just eight months, and the support from the recycling machine supplier has been incredible. Last month, when a sensor on the hydraulic cutter equipment malfunctioned, their technician was on a plane to Jakarta the next day. They didn't just sell us a machine—they built a relationship. Today, we're not just a recycling company; we're a model for sustainable waste management in Indonesia. And it all started with the right equipment."
