From post-consumer PET bottles to certified hollow, hollow-conjugated and solid staple fiber — produced at our own 7.5-hectare plant in Tangerang, audited to GRS and OEKO-TEX Class I, and trusted by buyers across five continents.
PT. HARVESTINDO INTERNATIONAL operates a fully integrated recycling-to-fiber plant in Pasar Kemis, Tangerang, Banten — turning post-consumer PET bottles into hollow and solid polyester fiber under one roof, with no subcontracted processing.
Four product families — hollow, hollow-conjugated and solid grades — in raw-white, solution-dyed green and black, with multiple denier and cut-length combinations for filling and nonwoven applications.

Single-wall hollow profile that traps air for lightweight loft and warmth. The workhorse filling fibre for bedding and outerwear programmes.

Bicomponent conjugated fibre with permanent 3D spiral crimp. Delivers resilient, spring-like recovery and lasting loft — the premium choice for duvets and pillows.

Solid recycled fibre with a dense, full cross-section and a uniform spun-in black — the economical grade for nonwoven lines, wadding and programmes where price matters more than loft.

Clean raw-white solid fibre made from the same post-consumer PET bottles — a neutral base for nonwovens, wadding and blend spinning, and the cost-efficient option where hollow loft is not required.

Tested hollow ratio comfortably above the ≥12% industry standard — more trapped air, more warmth per gram.
Recovery rate well above the ≥70% benchmark. Filling stays lofty after repeated compression.
The hollow core cuts weight while keeping support — around 20% lighter than ordinary solid polyester fibre.
Permanent 3D crimp delivers high bulkiness and a springy hand feel that survives filling and washing.
Trapped air inside the fibre core insulates against cold — the physics behind warmer, lighter bedding.
Mechanical recycling through finished fiber happens entirely in-house — full chain-of-custody under GRS.
Internationally recognised standards, verified quality. A GRS Transaction Certificate is issued for every shipment, so the paperwork matches the cargo.
Every step — sorting, washing, flaking, spinning, conjugating and baling — happens inside our own walls in Tangerang.
