Plastic Recycling – Sorteco Innovations Pvt. Ltd.

Granular Precision Sorting
Beyond basic polymer ID

What We Do

A Paradigm Shift in Plastic Recycling

Our AI-powered sorting solution goes far beyond traditional methods. By harnessing the sophisticated capabilities of computer vision and deep learning, our system achieves an unprecedented level of accuracy in identifying, classifying, and separating plastics — at true industrial throughput.

We don't stop at basic polymer identification. Sorteco's technology discerns plastics by polymer type, brand, colour, Melt Flow Index, and original end-use application. This granular level of sorting yields a pure, uncontaminated input stream — the foundation of genuinely high-grade recycled pellets.

The direct result? Recyclers can confidently produce commercially valuable rPET and rPP that meet the stringent demands of a true circular economy — including food-contact and bottle-to-bottle grade applications.

        This isn't incremental improvement. It's a fundamental leap toward unlocking the inherent value hidden within our plastic resources — one smart sort at a time.
      

How It Works

From Bale to Valuable Output — 5 Steps

Our intelligent sorting pipeline transforms contaminated plastic waste into clean, commercially valuable material streams with consistent, measurable results.

Infeed & Conveying

Material is fed onto high-speed conveyor belts, spread into a single layer for optimal vision scanning.

AI Vision Scanning

Hyperspectral, NIR, UV, and colour cameras capture material signatures in real time at high throughput.

Classification

Deep learning models classify each object by polymer type, grade, colour, MFI, brand, and application.

Precision Ejection

Targeted air jets eject specific material fractions with millisecond accuracy — no cross-contamination.

Clean Output Streams

Separated, high-purity material fractions are collected for direct use in recycling or reprocessing lines.

Plastic Identification

Every Resin Code. Sorted with Precision.

Our AI models are trained to identify all major plastic resin codes — ensuring no valuable material is misclassified or lost to landfill.

PET

Polyethylene Terephthalate

The most recycled plastic globally. Found in beverage bottles, food trays, and polyester fibres. Our AI achieves 98%+ purity for bottle-to-bottle grade rPET output.

Water BottlesFood TraysPolyester FibreBeverage Containers

HDPE

High-Density Polyethylene

Durable, chemical-resistant plastic used in milk jugs, detergent bottles, and pipes. Sorted by blow vs injection grade for maximised downstream value.

Milk JugsDetergent BottlesPipesToys

PVC

Polyvinyl Chloride

Used in window frames, pipes, flooring, and packaging films. Precise detection prevents PVC contamination in PET streams — a critical purity requirement.

Window FramesPipesFlooringCables

LDPE / LLDPE

Low-Density Polyethylene

Flexible packaging staple — found in cling wraps, squeezable bottles, and HM carry bags. Our system separates food-grade from non-food-grade flexible PE.

Cling FilmHM BagsSqueeze BottlesBubble Wrap

PP

Polypropylene

Widely used in food containers, automotive parts, and woven sacks. Sorted by melt flow index and application — delivering consistent rPP pellets for remanufacture.

PS / EPS

Polystyrene & Expanded PS

From disposable cutlery to foam packaging, PS streams are identified and separated accurately — enabling routes to recycling that are otherwise economically unviable.

The Challenge

Why Manual Sorting Falls Short

The global plastic recycling industry loses billions in material value every year — not because the plastic isn't there, but because it can't be sorted accurately enough to use.

⚠️

Invisible ContaminationMany contaminants — foreign polymers, dark additives, barrier coatings — look identical to clean material but destroy batch quality.

🐢

Human Speed & Fatigue LimitsManual sorters can process a fraction of what's needed, introduce inconsistency, and cannot distinguish polymer grades visually.

📉

Rejected Material & Revenue LossImpure output streams are downgraded or rejected entirely, converting recoverable material into a landfill cost rather than a revenue source.

Sorteco AI Solves All ThreeHigh-speed, always-on AI vision processes material 24/7 with sub-millisecond detection — making contamination visible and removal precise.
