Assam HDPE Bottle Plastic Granulator Success Case, High-Purity & Profitable

Mr. Raju, a high school-educated businessman in Guwahati, Assam, operates a medium-sized plastic recycling factory with 20 employees. With 5 years of experience in the plastic recycling industry, he specializes in processing HDPE bottles collected from local markets and beverage factories. Assam generates 24,970.88 tonnes of plastic waste annually, with HDPE bottles accounting for 25% of the total—but the city’s plastic waste treatment rate is less than 1/3, leaving ample market space for recycling. Mr. Raju’s factory previously used a local plastic granulator, but the granulated HDPE particles had low purity, making it difficult to sell at a competitive price and limiting his profitability and ability to expand his customer base.

The Challenge

Mr. Raju faced three main challenges in his HDPE bottle granulation business. First, the traditional plastic granulator lacked an effective filtering system, resulting in 12% of the HDPE particles containing impurities (such as sand and plastic fragments)—confining them to low-grade sales (₹45/kg). Second, the machine’s poor plasticization effect led to uneven particle size, with 20% of the particles being too small or too large—increasing product waste. Third, unlike other plastic granulator suppliers, the local manufacturer offered no technical support, leaving Mr. Raju unable to resolve the low particle purity issue. He needed a high-purity HDPE plastic granulator to improve product quality, boost profitability, and tap into the high-end market.

The Solution

We customized a high-purity plastic granulator (model: LGSJ-130) for Mr. Raju, tailored to HDPE bottle processing in Assam, with the following configuration and technical parameters:

• Multi-layer filtering system (3 layers of filter screens), removing 99.8% of impurities from HDPE bottle fragments to ensure particle purity.
• Precision plasticization system: Screw L/D ratio 35:1, with temperature control accuracy ±1℃—ensuring uniform particle size (error ≤0.5 mm) and reducing product waste by 90%.
• Hydraulic screen changer with automatic pressure detection, allowing screen replacement without stopping the machine—ensuring stable production and consistent particle quality.
• Technical parameters: Screw diameter 130 mm, power 22 kW, production capacity 120 kg/h, daily output 0.96 tonnes, particle size 3-5 mm (adjustable).
• Pre-sales: Our technical team tested his HDPE bottle samples and adjusted the machine parameters for optimal granulation effect. Post-sales: 1-year warranty, free technical training, and on-site technical support whenever needed—helping him resolve the low particle purity issue.

The Results

After 4 months of operation, the plastic granulator significantly improved Mr. Raju’s product quality and profitability:

• Particle purity: Increased from 88% to 99.8% with no impurities, upgrading the particle grade from low-grade to high-grade. The selling price rose from ₹45/kg to ₹60/kg.
• Product waste: Reduced from 20% to 2%, saving 17.28 tonnes of raw materials annually—worth ₹1.0368 million.
• Production capacity: Daily output increased from 0.8 tonnes to 0.96 tonnes, boosting monthly revenue by ₹43,200.
• Market competitiveness: His HDPE particles now supply 2 major plastic pipe factories in Assam under a long-term cooperation agreement.

Mr. Raju commented: “This plastic granulator has changed my business! It produces high-purity, uniform particles that sell at a much better price. The technical support is excellent, and I no longer worry about product quality—my profitability has increased by 33%!”

FAQ

Q1: Can this plastic granulator process other types of HDPE waste besides bottles?
A1: Yes, it can also process HDPE pipes and containers, making it suitable for the diverse HDPE waste in Assam.

Q2: How often do I need to replace the filter screens?
A2: The filter screens can be used for 30 days, and we provide free filter screens for the first 6 months—reducing your maintenance costs.
