Andhra Pradesh PP Woven Bag Plastic Granulator Success Case, High-Efficiency Energy-Saving

Published: 8 4 月, 2026

Based in Visakhapatnam, Andhra Pradesh, Ms. Lakshmi operates a medium-sized plastic recycling workshop with 15 employees. With a high school education, she launched her business in 2020, driven by Andhra Pradesh’s 2025-30 Circular Economy and Waste Recycling Policy—an initiative focused on promoting waste-to-wealth conversion and supporting MSMEs in the recycling sector. Her workshop specializes in processing waste PP woven bags sourced from local agricultural markets and port logistics hubs. Notably, Andhra Pradesh generates 46,222 tonnes of plastic waste annually, with woven bags accounting for 35% of this total. Initially, Ms. Lakshmi relied on a low-cost local plastic granulator, but it failed to keep up with growing demand and policy compliance standards, resulting in lost business opportunities and potential penalties for non-compliance.

Plastic Granulator

The Challenge

Ms. Lakshmi encountered three critical challenges that hampered her business growth and ability to meet local environmental regulations. First, the traditional plastic granulator featured a low screw length-diameter ratio (L/D=28:1), leading to inadequate plasticization of PP woven bag fragments. This resulted in 18% of the granulated products having air bubbles and black spots, making them unsuitable for high-end injection molding factories. Second, the machine lacked an efficient vacuum exhaust system, leaving moisture (up to 12%, due to Visakhapatnam’s coastal humidity) in the recycled PP material—compromising granule quality and causing frequent machine jams. Third, unlike other plastic granulator suppliers, the previous manufacturer offered no after-sales training or maintenance support, leading to 8-10 hours of downtime per month and disrupting production schedules. Ms. Lakshmi needed a high-quality automatic plastic granulator to resolve these pain points, ensure policy compliance, and enhance her market competitiveness.

The Solution

We customized a high-efficiency plastic granulator (model: LGSJ-150) tailored to Andhra Pradesh’s market demands and Ms. Lakshmi’s specific processing needs, with the following professional configuration and technical parameters:

Screw L/D ratio: 38:1, crafted from high-wear-resistant alloy steel to ensure full plasticization of PP woven bag fragments and eliminate air bubbles.
Dual-position vacuum exhaust system, effectively removing moisture (reducing content to below 2%) and volatile substances from printed woven bags to improve granule purity.
Hydraulic screen changer, enabling online screen replacement without stopping the machine—reducing downtime by 90% compared to manual screen changers.
PLC full-automatic control system with touchscreen operation, requiring only 1 operator to monitor the entire granulation process and cutting labor costs by 30%.
Pre-sales on-site survey: Our technical team visited her workshop to assess space layout and power supply, adjusting the machine size to fit her existing facility. Post-sales support: 3 days of on-site employee training, 24/7 online technical assistance, and free replacement of wearing parts within 6 months—exceeding the service standards of local Indian suppliers.

The Results

After 3 months of operation, the plastic granulator delivered remarkable, verifiable results:

Production capacity: Increased from 120 kg/h to 170 kg/h, with a daily output of 1.36 tonnes (based on an 8-hour workday)—fully meeting the demand of local injection molding factories.
Energy efficiency: Unit energy consumption reduced by 18% (from 32 kWh/tonne to 26.24 kWh/tonne), saving approximately ₹12,000 in monthly electricity costs.
Product quality: The pass rate of PP granules rose from 82% to 99%, with no air bubbles or black spots—meeting injection molding grade standards. The granule price increased by ₹5/kg, boosting monthly revenue by ₹20,800.
Downtime: Reduced from 8-10 hours/month to 0.5 hours/month, significantly improving production efficiency.

Ms. Lakshmi commented: “This plastic granulator is a game-changer for my business! It’s efficient, energy-saving, and easy to operate, and the after-sales service is impeccable. Now I can meet policy requirements and sell high-quality granules at a better price—my business has grown by 40% in just 3 months!”
