About SLS (PVT) LTD

Industrial PET Recycling & Flakes Manufacturing in Bangladesh

SLS (PVT) LTD is a Bangladesh-based manufacturer, supplier, and exporter of recycled Polyethylene Terephthalate (rPET) flakes. Operating from Dhaka, we collect and process post-consumer plastic beverage containers into high-purity industrial raw material for international manufacturers.

Our facility operates dedicated sorting, grinding, and washing lines designed to convert discarded plastic bottles into production-ready flakes. We eliminate common processing bottlenecks—such as high moisture, foreign polymer fines, and PVC contamination—by enforcing multi-stage friction washing, hot chemical cleaning, and strict float-sink density separation.

Our Environmental Commitment

SLS (PVT) LTD operates on a zero-compromise environmental and resource-efficiency policy. We minimize the carbon footprint of our operations by optimizing regional recovery routes and reducing transit times for raw plastic bottle bales arriving at our facility.

By building direct, traceable partnerships with domestic collection networks across Bangladesh, we divert discarded post-consumer PET containers from landfills, open waterways, and municipal waste streams. Sourcing regionally not only strengthens local recycling formalization, but it also ensures an uninterrupted, energy-efficient supply loop that converts urban plastic waste into high-grade industrial raw materials for global circular manufacturing.

Our company mission is to exceed expectations

Powering Circular Manufacturing Through Precision PET Recycling

At SLS (PVT) LTD, our mission is to convert post-consumer plastic waste into high-purity industrial raw materials that global manufacturers can rely on without compromise. We operate at the intersection of environmental recovery and technical manufacturing, transforming discarded PET beverage containers in Bangladesh into consistently graded, export-ready recycled PET flakes.

  • Purity at the Processing Level: Strict sorting, hot washing, and density separation ensure low PVC, minimal moisture, and uniform sizing.
  • 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.

Used to Produce

SLS (PVT) LTD executes a disciplined, multi-stage mechanical recycling workflow. Post-consumer PET bottles undergo rigorous manual and optical sorting, wet granulation, high-temperature washing, and continuous float-sink density separation to strictly control PVC and moisture levels. This systematic processing ensures our washed rPET flakes feed seamlessly into downstream polyester fiber spinning, rigid sheet extrusion, and packaging film production without melt-line disruptions.
