HDPE LDPE Recycling Plant Manufacturer

As a specialist HDPE & LDPE recycling plant manufacturer in India, we engineer robust lines to convert post-consumer and post-industrial films, liners, carry bags, and rigid items into uniform, high-value granules. Our solutions cover shredding, agglomeration, hot & cold washing, friction cleaning, drying, melt filtration, degassing, and pelletizingâ€”balanced for Indian scrap profiles, utilities, and compliance.

Working Principle and Process Flow for HDPE/LDPE

HDPE/LDPE recycling begins with inspection and size reduction, followed by float-sink density separation to remove contaminants. Film flakes undergo hot wash and friction rinse to control ash and odour. In extrusion, force-feed or compactor systems ensure steady throughput; multi-stage filtration and vacuum degassing stabilise MFI and colour. Die-face cutting or strand pelletizing yields consistent granules. SCADA monitors kWh/kg, temperature bands, and output quality for traceability and preventive maintenance.

Plant Types We Manufacture

Compact LDPE film recycling lines (150â€“300 kg/hr) with agglomerator + vented extruderâ€”ideal for decentralised collection hubs and urban MRFs.
Medium-scale HDPE/LDPE twin-line systems (500â€“900 kg/hr) with redundancy to minimise changeovers and maintain uptime during maintenance.
High-throughput blown-film grade plants (1000â€“1500 kg/hr) featuring force-feed extruders, back-flush screen changers, and automatic pellet length control.
Rigid HDPE drum/crate lines with label remover, metal separation, intensive washer, and multi-stage drying tailored to higher bulk densities.
Wash-plus-pelletize turnkey packages including water-recycling modules, effluent treatment, and odour-control options for challenging feedstocks.

Key Features & Specifications

Energy-efficient motors with VFDs; documented kWh/kg benchmarks for films vs. rigids to plan operating costs accurately.
Automatic screen changers (back-flush/continuous), multi-zone heating, and dual-vent vacuum degassing for clean, stable melt.
Compactor/force-feed for light films; gravimetric dosing for calcium-filled or blended recipes; melt pumps for pressure stability.
SS304 wash contact parts, adjustable chemistry dosing, and friction wash to reduce ash, gels, and odour carry-over.
PLC-SCADA with recipe control, alarm logs, remote diagnostics, and preventive maintenance prompts for predictable uptime.

Applications of Recycled HDPE & LDPE

Blown film for carry bags, liners, courier/mailers, agriculture mulch, and shrink films with defined MFI windows and dart impact targets.
Extrusion and thermoforming sheets for packaging and protective applications where printability and seal strength are critical.
Injection-moulded crates, bins, caps, and houseware using rHDPE/rLDPE blends to balance stiffness, impact, and warpage.
Cable sheathing, pipes, and conduit where ESCR, UV stability, and carbon-black dispersion are controlled through process recipes.

Why Choose Our HDPE/LDPE Recycling Plants

Lower lifecycle cost through optimised energy consumption, water recirculation, and standardised spares available pan-India.
Consistent pellet quality from robust washing, multi-stage filtration, and degassingâ€”reducing gels, odour, and film defects downstream.
Higher productivity via automatic dosing, quick screen changes, steady compaction/feeding, and recipe-based start-ups.
Compliance & sustainability support with traceability data, EPR alignment, safety guarding, and audit-ready documentation.

Manufacturing & Supply Across India

We design, fabricate, and commission HDPE/LDPE recycling plants sized for Indian scrap realitiesâ€”thin films, printed laminates, foils, and rigid scrap. Deliverables include layout engineering, installation, operator training, FAT documents, and warranty support. Service reach spans Ahmedabad, Mumbai, Delhi-NCR, Coimbatore, Hyderabad, and more. Upgrades such as stainless contact parts, water-recovery systems, odour mitigation, and SCADA analytics are available to future-proof your investment.

Maintenance and Safety Tips

Track bearing temps, gearbox noise, and vacuum levels; act on deviations early to prevent melt degradation and specks.
Maintain wash chemistry TDS and pH; schedule tank cleaning and screen replacements to keep ash and gels under control.
Calibrate load cells, thermocouples, and pressure sensors; verify MFI against recipe targets for each polymer stream.
Enforce lockout-tagout, PPE, and hot-surface signage; check guards and E-stops at every shift change.
Stock critical spares (heaters, screens, seals, knives) in a dry, labelled store with FIFO practices and part traceability.

FAQs â€“ HDPE LDPE Recycling Plant Manufacturer

1. What throughput should I select for film vs. rigid HDPE? +

Match throughput to scrap availability, shift planning, and downstream demand. Films often need compactor/force-feed to stabilise density; rigids can run higher bulk rates but require intensive washing and drying. Modular scaling keeps quality stable as you expand.

2. Can one line handle printed and unprinted LDPE films together? +

Yesâ€”pre-segregation helps, but hot wash, friction cleaning, and multi-stage filtration are essential. Use recipe-based degassing and stabilisers to manage odour and gels when processing printed/laminated inputs.

3. Which utilities are critical for stable operation? +

Three-phase power, process water with recirculation, and compressed air are typical. Provide ETP for effluents and consider gensets or UPS for PLC/SCADA to avoid data loss during grid fluctuations.

4. How do I achieve consistent film-grade MFI? +

Stabilise feed density with compaction, maintain melt temperature zones, and use dual-vent degassing. Check MFI per batch and adjust screw speed/temperature and filtration fineness as needed.

5. What after-sales support is included? +

Installation & commissioning, operator training, preventive maintenance schedules, remote diagnostics, and assured spares. Define response times and performance guarantees tied to throughput, ash, odour, and pellet consistency.
