Sri Lanka Colombo, Port Plastic Containers, Corrosion-Resistant Plastic Recycling Machine Success Case

Background: Mr. Dilshan Fernando, a 40-year-old with a diploma in marine engineering, launched his plastic recycling business in 2022 near Colombo Port—Sri Lanka’s largest seaport and a key hub for international trade. His 1,200-square-meter medium-sized factory employs 18 workers, focusing on processing waste plastic containers (drums, crates, bottles) discarded at the port. Colombo Port handles over 5 million tons of cargo annually, generating 7 tons of plastic waste each day—much of this waste is contaminated with saltwater and chemical residues. As a former port engineer, Dilshan witnessed the port’s plastic pollution crisis, which harms coastal ecosystems and violates Sri Lanka’s Marine Pollution Control Act. He invested in a corrosion-resistantPlastic Recycling Machine to process salt-contaminated plastics, aligning with the port’s “Green Port” initiative. A high-qualityplastic equipment  was essential to withstand the harsh coastal environment.

The Challenge

Mr. Dilshan faced three critical challenges. First, the plastic containers from Colombo Port had a high saltwater content (up to 7%), which caused rapid corrosion of the traditional Plastic Recycling Machine he initially tested—screws and feeding hoppers needed to be replaced every 2 months, increasing maintenance costs by 34%. Second, the containers varied in size and material (PE, PP, PET), leading to inefficient sorting and processing; his daily capacity was only 4.2 tons, which was unable to keep up with his 10-ton daily raw material collection. Third, chemical residues on the containers caused foul odors and black spots in recycled particles, reducing their market value and resulting in a qualification rate of just 62%. Additionally, he needed a plastic equipment  that could comply with Sri Lanka’s strict environmental standards (VOC < 40 mg/m³) to avoid penalties. Local plastic equipment  suppliers could not provide corrosion-resistant solutions, leaving him stuck.

The Solution

We provided Mr. Dilshan with a TL-850 corrosion-resistant Plastic Recycling Machine, customized for Colombo Port’s salt-contaminated plastics and local environmental standards—ideal for Sri Lanka’s coastal recycling projects. The specific configuration of this plastic equipment e, a high-quality corrosion-resistant plastic equipment , includes:

• 316 stainless steel screw and feeding hopper, designed to resist saltwater and chemical corrosion, extending part service life to 10 months and reducing maintenance costs for the plastic equipment .
• Intelligent sorting system with optical sensors, which automatically separates PE, PP, and PET plastics, reducing manual sorting by 85% and improving processing efficiency with the plastic equipment .
• Multi-stage cleaning system (alkaline cleaning + high-pressure rinsing), which removes 99% of saltwater and chemical residues, eliminating odors and black spots in recycled particles with the Plastic Recycling Machine.
• Waste gas purification system with activated carbon filters, reducing VOC emissions to below 35 mg/m³—fully complying with Sri Lanka’s environmental standards for theplastic equipment .
• Free on-site installation, 24/7 online technical support, and on-site maintenance within 24 hours in Colombo, plus a 1-year warranty for theplastic equipment .

The Results

After 5 months of operation, the Plastic Recycling Machine transformed Mr. Dilshan’s business. Corrosion issues were completely eliminated, cutting maintenance costs by 68% (saving 32,000 LKR per month) with theplastic equipment . The daily processing capacity of the plastic equipment   increased from 4.2 tons to 11 tons—a 162% improvement—allowing him to process all collected port plastic waste. The multi-stage cleaning system of the plastic equipment  boosted the qualification rate from 62% to 98%, with particles suitable for high-grade packaging. The selling price of recycled particles increased by 35% (from 45 LKR/kg to 60.75 LKR/kg), boosting his profits. Mr. Dilshan signed a long-term supply contract with a local plastic drum manufacturer, increasing his monthly income by 95% (from 1.2 lakh LKR to 2.34 lakh LKR). “This plastic equipment  is corrosion-resistant and high-quality—it handles port waste effortlessly and produces particles that sell for a premium,” Mr. Dilshan said. His business was also recognized by the Colombo Port Authority for reducing coastal pollution.
