SLS (PVT) LTD manufactures clean, color-sorted, and hot-washed recycled PET flakes in clear, green, brown, and lemon grades. Engineered for demanding industrial extrusion and fiber spinning, our flakes undergo multi-stage friction washing, chemical cleaning, and float-sink density separation to strictly control PVC, label residues, and polyolefin contaminants. Following centrifugal dewatering and continuous hot-air drying, our finished rPET flakes achieve minimal residual moisture and uniform flake sizing—delivering dependable, container-load raw material supply for international manufacturers.

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.
