OUR IDENTITY
Engineering High-Purity Raw Materials from Recovered Plastics
Headquartered in Dhaka, Bangladesh, SLS (PVT) LTD is a dedicated mechanical recycler, manufacturer, and exporter of recycled Polyethylene Terephthalate (rPET) flakes. We specialize in processing post-consumer plastic beverage containers into production-ready industrial raw materials.
International buyers sourcing secondary polymers often face inconsistent sorting, high moisture levels, and unexpected PVC contamination that cause expensive downtime in extrusion and spinning lines. SLS was built to eliminate these variables. By integrating systematic manual color separation, mechanical de-labeling, high-speed wet granulation, and intensive caustic hot washing, our operations produce rPET flakes that meet rigorous global manufacturing standards.
Dedicated Color Streams: Pure Clear, Washed Green, Amber Brown, and Lemon Flakes.
Contamination Control: Multi-point testing to keep PVC below 50 ppm and moisture under 1.0%.

MANUFACTURING INFRASTRUCTURE
Built for Export-Grade Mechanical Recycling
Our processing plant in Bangladesh operates purpose-built mechanical recycling lines configured to optimize flake cleanliness and particle sizing.
High-Capacity Infeed & Sorting
Debaling stations and wide, well-illuminated inspection conveyors allow our sorting teams to separate bottles by color while rejecting foreign polymers (PVC, HDPE) and non-plastic contaminants before cutting begins.
Caustic Hot & Friction Washing
Our lines combine mechanical friction washers with high-temperature caustic wash tanks ($85^\circ\text{C} – 90^\circ\text{C}$) to strip beverage syrups, dissolve label adhesives, and neutralize surface contaminants completely.
Float-Sink Density Separation
Continuous water density baths exploit specific gravity differences: high-density PET flakes sink directly to the extraction screw, while lightweight polypropylene and polyethylene bottle caps float away.

PURPOSE & INTEGRITY
Our Corporate Mission
To convert post-consumer plastic waste into dependable, high-purity secondary raw materials that help global manufacturers transition away from virgin petrochemical resins.
Purity at the Processing Level
Strict sorting, hot washing, and density separation ensure low PVC, minimal moisture, and uniform sizing to prevent extruder disruptions.
Dependable Cross-Border Supply
Industrial jumbo bag packaging and direct container shipping via Chattogram Port guarantee consistent, reliable delivery.
Tangible Circular Impact
Diverting post-consumer bottles from local landfills into industrial-grade rPET helps global manufacturers reduce virgin resin reliance.

QUALITY VERIFICATION
Batch-by-Batch Verification Before Dispatch
At SLS (PVT) LTD, quality assurance is an active in-line protocol, not a routine sign-off. We understand that even fractional increases in PVC or moisture content create melt instabilities, clogged spinneret packs, and brittle extruded sheets.
Our on-site testing facility verifies critical technical parameters for every production lot:
- Thermal Baking Tests: Laboratory oven exposure to identify and isolate PVC contamination below 50 ppm.
- Moisture Analysis: Ensuring centrifugal dewatering and heated pipeline drying maintain moisture under 1.0%.
- Polyolefin Flotation Verification: Continuous float testing ensuring zero residual floating caps (PP/PE < 50 ppm).
- Sieve Size Classification: Verifying standard 3–10 mm flake distribution with dust levels held under 1.0%.

LOCAL IMPACT, GLOBAL SUPPLY
Responsible Domestic Sourcing in Bangladesh
Our environmental commitment begins at the collection level. By sourcing post-consumer PET bottles directly through regional recovery channels across Bangladesh, we shorten raw material transit distances, lower transportation carbon footprints, and formalize local collection networks.
Every metric ton of recycled PET flakes produced by SLS diverts thousands of discarded soda and mineral water bottles from municipal landfills, city drainage systems, and riverways. We convert local plastic waste into an exportable industrial commodity that feeds circular manufacturing globally.
