Capacity & Equipment Scale

Our six core capabilities define what we can deliver — from raw material throughput to quality assurance and food-grade processing.Purity, consistency, and stability.Together they enable us to support brand owners, converters, and OEMs with the recycled plastics they need at scale.

協治關鍵能力

One of Taiwan's Few Vertically Integrated Recycling-to-Processing Operations

A supplier that controls quality from the source

Shyechih is one of the few companies in Taiwan to own both a collection network and a processing operation, with full control over collection, sorting and pre-treatment. This lets us manage material consistency starting from the baled feedstock, rather than patching problems downstream.

Reliable Supply Capacity

Multi-site footprint × dependable supply

Shyechih operates four sorting plants and one processing plant across southern Taiwan, with an average throughput of 3,000 tonnes per month. Multi-plant coordination avoids single-point risk and keeps supply uninterrupted.

Precision Sorting Technology

A three-layer architecture: turning the uncontrollable into the controllable

Shyechih builds quality stability on technology

NIR spectroscopy sorting

  • More consistent material
  • Material variances are quickly screened out

AI vision models

  • Details NIR can't catch — food-grade status, brand, color, contamination, regulatory compliance
  • AI inspection safeguards quality

Multi-stage washing (hot wash × ultrasonic)

  • Cleaner contamination removal
  • Reduced odor
  • Supports higher-grade applications

Recycled-Material Consistency

The more consistent the collection-side quality, the more stable the recycled material

Shyechih turns collection-side quality fluctuations into “material that manufacturers can trust” through its sorting and processing flow. Key recycled-material indicators — color tone, moisture content, contamination level, MFI/IV — are kept stable.

Food-Grade Processing Capability

Ready for bottle-to-bottle

Shyechih has built a food-grade PET processing line that uses a stricter washing process to deliver higher-purity, low-residue, low-contaminant PET flake.

This line is designed to support brands' bottle-to-bottle programs — turning PET back into PET to close the loop.

Confidence in Sustainability Management

Starting from the supply chain, making sustainability a practicable standard

Driving circular materials takes more than vision — it takes a supply-chain foundation. Through technology, upstream management and consistent material quality, Shyechih lets companies pursue sustainability and the circular economy in a more practical way.
